Purpose
Metropolitan, "metro," networks are the communications networks that link homes and businesses to larger, long-distance core networks. These networks are complex because they are filled with both old and new networking equipment and must carry all types of service traffic, including voice, data and video.
Driven by the exponential growth of the Internet, requirements for metropolitan optical transport networks are changing quickly from pure circuit networks to hybrid networks.
This evolution requires metro access networks to aggregate the local loop or last-mile bandwidth in order to integrate with the high-speed core/backbone networks. These requirements are driving metropolitan network evolution from traditional SONET multiplexers into more flexible, higher-speed, data-aware platforms-a necessity for optical edge solutions.

• LNW82 pack supports up to 8 OC-3 interfaces, 8 OC-12 interfaces, or 2 OC-48 interfaces. Although mixing of interface rates is supported, OC-48 interfaces are only supported on ports 1 and 5. When one of these ports is operating at the OC-48 rate, then the next three adjacent ports cannot be used. The backplane interfaces can operate at 2.5 Gb/s or at 622 Mb/s, supporting all VLF-compatible low-speed packs.
The LNW82 provides a total of 110G of Input/Output interfaces. The LNW82 has
130G of usable STS-1 fabric and 10G of usable VT fabric. (The pack could support a
170G STS-1 fabric and a 20G VT fabric with future tributary enhancements.)
• LNW504 pack supports up to 4 OC-192 interfaces or up to 3 OC-192 interfaces and 4
OC-48 interfaces. Although mixing of interface rates is supported, OC-192 interfaces are only supported on ports 1–4, and OC-48 interfaces are only supported on ports
5–8. The backplane interfaces can operate at 10 Gb/s and/or 2.5 Gb/s, supporting all
VLF-compatible low-speed packs. The LNW504 provides a total of 180G of
Input/Output interfaces. The LNW504 has 220G of usable STS-1 fabric and 30G of usable VT fabric. (The pack could support a 240G STS-1 fabric and a 45G VT fabric with future tributary enhancements.)
Very Large Fabric (VLF) Main circuit packs drastically increase the overall switch fabric capacity of Alcatel-Lucent 1665 DMX. Their ports can be equipped with PTMs. The
LNW59 pack supports OC–192 (1.3SR1, 1.5IR2, 1.5LR2, and DWDM) pluggable optics.
The LNW82 multi-rate pack supports OC-3 (1.3SR1, 1.3IR1. 1.3LR1 and CWDM)
OC-12 (1.3IR1, 1.3LR1, 1.5LR2, and CWDM), or OC-48 (1.3SR1, 1.3LR1, 1.5LR2, and
DWDM) pluggable optics. The LNW504 pack supports OC-48 (1.3SR1, 1.3LR1,
1.5LR2, and DWDM) and OC-192 (1.3SR1, 1.5IR2, 1.5LR2, and DWDM) pluggable optics.
VLF cards can also function in headless mode, providing switching and synchronization functionality without being equipped with optics. The VLF packs enable true 0x1 operation among the tributary slots by supporting unprotected 0x1 interfaces located in the same function or growth unit. All tributary circuit packs, with the exception of the
LNW7, are supported by the VLF packs.

Other hardware features
Alcatel-Lucent 1665 DMX also supports the following hardware:
Pluggable transmission modules (PTMs)
PTM optics are pluggable optics. Circuit packs using pluggable optics do not come equipped with optics; you can order only the number and type of optics required at the time of installation. Additional optics can then be ordered as new services are required which makes Alcatel-Lucent 1665 DMX interface density scalable to meet the unique needs of each customer. The PTM optics also allow for some versatility in the span lengths and rates that can be covered by the same pack.
PTMs are either SFPs or XFPs. OC-3, OC-12, OC-48, Fast Ethernet, and Gigabit Ethernet ports use optical SFPs. OC-192 port use optical XFPs. Electrical SFPs are also available for Fast Ethernet and Gigabit Ethernet ports The LNW705 (10G Muxponder) packs use
SFPs on the 8 client ports and an XFP on the OTU2 port.
The LNW63/64/87/170 packs support dual-function electrical SFPs that are provisionable for 100 or 1000 Mbps (electrical FE or GbE) traffic. They conform to the IEEE802.3
standards for 100BASE-T and 1000BASE-T in the respective settings (IEEE802.3z and
IEE802.3ab). Connectivity is provided for an RJ-45 Cat 5 cable and the SFP has a maximum span length of 100 meters.
External optical amplifiers
For OC-48/192 spans of up to 140 km, Alcatel-Lucent offers external optical amplifiers.
The external optical amplifier is a stand-alone shelf and can be used with both OC-48 and
OC-192 optics.

External optical amplifiers consist of one booster and one pre-amplifier part. The booster part is connected via a Dispersion Compensation Module (DCM) to the transmit interface of the respective OC-192 or OC-48 port unit. The pre-amplifier part is connected by means of a DCM to the receive interface of the associated port unit.
Passive optics units (POUs)
The Alcatel-Lucent Passive Optics Units (POUs) are a lower-cost solution to using
DWDM for transmitting large amounts of traffic on one fiber. This module fits into a bay frame, but reduces the number of Alcatel-Lucent 1665 DMX shelves in a bay to three.
The box does not require any electrical powering.
POU shelves are available to support the following applications:
• Optical add-drop module (OADM): 1, 2, or 4 wavelengths
• Optical add-drop module (OADM): one 1310 nm port and four 1550 nm ports
• 16 unidirectional/bidirectional wavelengths (2 versions): MUX/DMUX
• 32 wavelengths; 16 unidirectional/bidirectional wavelengths with a wavelength interleaver used to add another 16 wavelengths: MUXINT/DMUXINT
Cable management bracket
In the interest of helping customers organize the physical networking in their offices,
Alcatel-Lucent 1665 DMX provides a fiber management bracket that mounts to the apparatus blanks used in the unoccupied slots of the shelf. This bracket has hooks where fibers can be set until the pack to which they will be attached is installed. This bracket is available with either 16 or 24 LC fiber storage ports.
The bracket is designed to facilitate the organization and storage of pre-wired fibers that are expected to carry service to the shelf in the future. These brackets attach to the apparatus blanks via PEM nuts on the faceplate. PEM Nuts or PEM Fasteners are mounted flush on the faceplate. They provide a fixed receptacle to which the bracket can be screwed in.
This feature is available on both the standard and detectable apparatus blanks and also allows visibility via the CIT.
Electrical continuity test tool (LNW94)
Alcatel-Lucent 1665 DMX supports a circuit pack designed to aid technicians in the installation and maintenance of Electrical interfaces and cables. The Electrical Continuity
Test Tool (LNW94) can be placed in any Function Unit slot (A, B, C, and D) on the
Alcatel-Lucent 1665 DMX shelf. It is used to test the cables which will be connected to
DS1, DS3, or Ethernet electrical interfaces. LNW94 tests the integrity of electrical cables to both identify where trouble exists and which cables or DSX panels are faulty prior to installation and turn up.

In-service electric continuity test tool (LNW93)
The In-service Electrical Continuity Test Tool (LNW93) test circuit pack is used for upgrades in the Alcatel-Lucent 1665 DMX shelf. An in-service shelf might have a function unit with low capacity DS1 (LNW7) or DS3 (LNW16) packs. When these packs are upgraded with higher capacity packs (DS1, LNW8, DS3, LNW19B), as part of the upgrade procedure, new DS1 or DS3 connectorized cables are added to the DSX cross-connect frames and to the Alcatel-Lucent 1665 DMX shelf. The LNW93 pack is used to test out the new wiring without disrupting traffic on the in-service pack.
The LNW93 is very similar to the LNW94 test tool except that it has no backplane connectors for DS1 ports #1–28 or for DS3 ports #1–12. When the LNW93 is plugged in, it makes no contact with the wires on the backplane for those lower ports. Since there is no physical connection, the LNW93 does not interfere with the service of the pack in the other slot of the function unit. The LNW93 tests the integrity of electrical cables to both identify where trouble exists and which cables or DSX panels are faulty prior to installation and turn up of a high density DS1 or DS3 circuit pack.
Blank circuit packs
Alcatel-Lucent 1665 DMX provides blank cards to be used as fillers in unpopulated slots of the shelf. These fillers help to ensure proper air flow, cooling and EMC safety.
Some blanks can be detected and reported.
Alcatel-Lucent 1665 DMX supports two detectable blank circuit packs: LNW97 in an unequipped M2, LNW98 in unequipped Function and Growth slots.
The WaveStar
®
CIT reports the presence of a detectable blank in a slot by displaying a blank faceplate graphic instead of an empty slot graphic. No alarms are associated with the insertion or removal of the detectable blank.

Overview
This section briefly describes the major topologies supported for Alcatel-Lucent 1665
DMX.
High-speed (network interface) OC-192/48/12/3 UPSR for STS-n/VT1.5
Alcatel-Lucent 1665 DMX supports Unidirectional Path Switched Rings (UPSR) at the
STS-n and VT1.5 level. When both Main slots are equipped with OC-192/48/12 VLF or large VT fabric circuit packs, an STS-1/VT1.5 switching fabric (STS-1, STS-3c,
STS-12c, STS-48c, or STS-192c) supports the low-speed interfaces. OC-48/12 medium
VT fabric cards, supporting STS-1, STS-3c, STS-12c, and STS-48c are also available.
Each circuit pack establishes both an east-to-west and a west-to-east rotation on the ring.
A UPSR ring provides a very valuable and reliable foundation for services protecting against fiber cuts and node failures. On a per STS-n basis, Alcatel-Lucent 1665 DMX supports both revertive and non-revertive switching.
High-speed (Network interface) OC-192/48 BLSR for STS-1/VT1.5
Alcatel-Lucent 1665 DMX supports an OC-192/48 Bidirectional Line Switched Ring
(BLSR). When both Main slots are equipped with OC-192/48 high-speed circuit packs, an
STS-1 switch fabric supports the low-speed interfaces (STS-1, STS-3c, STS-12c, or
STS-48c. When both Main slots are equipped with VLF packs, in addition to low-speed interfaces (STS-1, STS-3c, STS-12c, STS-48c), STS-192c is also a supported rate. A
2-fiber bidirectional line-switched ring (BLSR) is a self-healing ring configuration in which bidirectional traffic travels over the same set of nodes in each direction.
Bidirectional switching makes use of redundant (protection) bandwidth on the bidirectional lines that interconnect the nodes in the ring to provide protection for traffic carried on the working bandwidth. Because the traffic is bidirectional, a single circuit does not necessarily consume bandwidth on every span in the ring. This leaves the spans between other nodes available for additional traffic. Therefore, with distributed switching patterns, a BLSR can carry more traffic than the same facilities could carry if configured for a unidirectional path-switched ring. In BLSR configurations, the VT switch fabric located in the MAIN packs is used only for Function Unit or Growth Slot hairpins.
Alcatel-Lucent 1665 DMX supports VT BLSRs on all high speed OC-192 interfaces and on high-speed OC-48 interfaces that have a 48 STS-1 VT fabric or VLF (LNW29,
LNW27, LNW56, LNW58, LNW59, LNW76, LNW82, LNW202, LNW502 ,LNW504).

Multiple BLSRs
Alcatel-Lucent 1665 DMX supports multiple BLSRs on the low-speed interfaces.
Alcatel-Lucent 1665 DMX supports 15 simultaneous BLSR protection groups in a single shelf. The 15 protection groups can be provisioned on any available OC-48 and OC-192 port pairs within the high-speed and low-speed groups.
True 0x1
When equipped with VLF Main packs (LNW59/LNW82/LNW504), Alcatel-Lucent 1665
DMX allows true 0x1 unprotected circuit pack applications. That means that any slot can be equipped with any pack (some restrictions apply). For example, an LNW170 could be used to provide switched Ethernet services in slot D1, while slot D2 could be equipped with another pack, like an LNW62. Two of the same circuit packs can also populate adjacent slots in the same group, yet certain restrictions apply. For more information on
0x1, including circuit pack/slot equipage restrictions, see
Chapter 6, “System planning and engineering” .
When VLF Mains are used, the 0x1 OCn application is used instead of 0x1Sn functionality. 0x1Sn is still supported when the shelf is equipped with non-VLF Mains.
0x1 is available on both low-speed/tributary packs, and VLF Main (M1/M2) interfaces.
When all lines on an OCn pack are set to 0x1, the pack becomes unprotected and the companion slot can be equipped with a different pack.
VT grooming and squelching
Alcatel-Lucent 1665 DMX supports GR-1230 compliant VT grooming and squelching on
OC-48/192 BLSRs. Alcatel-Lucent 1665 DMX also support the automatic generation of
VT squelch maps.
High-speed (network interface) OC-192/48/12/3 linear optical extensions
Alcatel-Lucent 1665 DMX supports 1+1 protected linear optical extensions. The high-speed linear optical extension may connect the Alcatel-Lucent 1665 DMX shelf, by way of OC-3/12/48/192 network interfaces in the MAIN slots, to an OC-3/12/48/192 node.
The following protection schemes are supported:
• Revertive, unidirectional 1+1
• Revertive bidirectional 1+1
• Non-revertive, unidirectional 1+1
• Non-revertive, bidirectional 1+1
You can change a 1+1 protection group from unidirectional to bidirectional in-service without deleting cross-connections.

Low-speed UPSRs (for STS-n termination and VT ring closure)
Alcatel-Lucent 1665 DMX can host multiple rings on the low-speed interfaces of the
Alcatel-Lucent 1665 DMX shelf. Each circuit pack establishes both an east-to-west and a west-to-east rotation on the ring. A UPSR ring provides a very valuable and reliable foundation for services protecting against fiber cuts and node failures.
Alcatel-Lucent 1665 DMX supports UPSRs on all lines of all equipped function group or growth slots.
Low-speed (tributary interface) linear optical extensions
Alcatel-Lucent 1665 DMX supports 1+1 protected linear optical extensions for data transport originating at a data device. The low-speed linear optical extension may connect the Alcatel-Lucent 1665 DMX shelf, by way of by way of OC-3/12/48/192 tributary interfaces in the Function or Growth slots, to an OC-3/12/48/192 node.
Single- and dual-homed ring extensions
Alcatel-Lucent 1665 DMX supports low-speed OC-3/12/48 0x1 protected broadband tributaries, including single- and dual-homed ring extensions. A DDM-2000 OC-3,
OC-12, FiberReach, Alcatel-Lucent 1665 DMXtend, Alcatel-Lucent 1665 DMX, or
Alcatel-Lucent 1665 DMXplore may be the add/drop multiplexer on the lower-speed ring.
Hairpinning
In "hairpinning" topologies, low-speed tributary traffic is routed into the system and back out without ever being placed on the high-speed (OC-12, OC-48 or OC-192) interfaces.
When a VLF Main pack is used, all cross-connects use the switch fabric located on the
VLF pack. Any switch fabrics located on low-speed, tributary packs are disabled when
VLF Mains are used.
Dual ring interworking
Alcatel-Lucent 1665 DMX supports UPSR DRI. The dual node ring interworking (DRI) cross-connections comply with Telcordia
®
GR-1400 (which refers to GR-253-CORE) standards. A service selector exists for each STS-N tributary provisioned for DRI.
Both DRI and dual homed rings are designed to protect against a failure of an interconnecting facility or a failure of the node at which the interconnection occurs. The choice of DRI vs. DHA is driven by the network topology. To provide protection when connecting between two UPSRs, DRI is used. To provide protection when connecting between a UPSR and a single NE, dual homing is used.

GbE Private Line
Alcatel-Lucent 1665 DMX GbE private lines (1000 Mbps) enable premium data transport services offering GbE transport with optional bandwidth provisioning up to full line-rate.
GbE private lines provide the user the ability to transport frames completely transparently between two Alcatel-Lucent 1665 DMX NEs. No VLAN knowledge or packet-layer provisioning is required by the user in this application. Simple, SONET cross-connect provisioning is all that is required when using "Private Line" or "no tag" mode. These
GbE capabilities allow the Alcatel-Lucent 1665 DMX to provide dedicated bandwidth for individual customers and fast SONET-layer restoration.
Fast Ethernet Private Line
Alcatel-Lucent 1665 DMX Fast Ethernet (10/100 Mbps) private lines enable premium data transport services offering 10/100 Mbps transport with optional bandwidth provisioning up to 100Mbps (variable bandwidth provisioning of 1, 2, or 3 STS1s. Fast
Ethernet private lines provide the user the ability to transport frames completely transparently between two Alcatel-Lucent 1665 DMX NEs. No VLAN knowledge or packet-layer provisioning is required by the user in this application. Simple, SONET cross-connect provisioning is all that is required. These Fast Ethernet capabilities allow the Alcatel-Lucent 1665 DMX to provide dedicated bandwidth for individual customers and fast SONET-layer restoration. LNW74 or LNW87 must be used to enable Fast
Ethernet private lines.
GbE packet rings
Alcatel-Lucent 1665 DMX supports Gigabit Ethernet (GbE) packet rings that enable cost-effective Internet access and business-to-business LAN services. GbE packet rings allow interworking among 10/100 Mbps and 1000 Mbps (GbE) Ethernet lines while
VLAN tagging ensures individual customer privacy. These GbE capabilities allow
Alcatel-Lucent 1665 DMX to support various Quality of Service (QoS) features, including fast packet-layer restoration.
4093 VLANs
Alcatel-Lucent 1665 DMX allows the provisioning of up to 4093 separate IEEE 802.1q
VLANs. VLANs are a way in which LAN users at the enterprise level, located on physically separated LAN networks, are assigned priority access privileges across a WAN backbone. Although they are in different locations, they appear to be on the same physical segment of an enterprise-level LAN. Thus, VLANs are logical groupings of various users, regardless of their physical location on the network.
Stacked VLANs (VLAN transparency)
Alcatel-Lucent 1665 DMX allows customer traffic to be identified and segregated using
"stacked" IEEE 802.1q VLAN tags. VLAN tags enable the formation of Virtual Private
Networks (VPNs) by segregating various units of traffic and isolating different

end-customers. This allows data from different customers to efficiently share common bandwidth while simultaneously ensuring a basic level of security for each customer
(hence VPN).
The notion of VLAN "transparency" comes from the fact that individual customer packets are tagged using a second tag, a default port tag (default port tag is provided by customer equipment). There is no need to coordinate VLAN tags between the customer and service provider. Therefore, customer packets are transmitted through a service provider's network "transparently".
G.8032 Ethernet ring protection
Alcatel-Lucent 1665 DMX support Ethernet Ring Protection (ERP) functionality, based on ITU-T G.8032 on the LNW170 circuit pack. This feature provides rapid (50ms) revertive switching for
• Physically-connected optical Ethernet links connected in a ring configuration
• Ethernet PTM-based ports
On the LNW170 Ethernet PTM-based ports, local signal failure is declared when any of the following conditions are present:
– Signal failure (LOS) detected on the port
– TX_FAULT bit active on optical PTMs (not on electrical PTMs)
– PTM failures (for example, rate check failure.)
– PTM removal
– port in Admin-down state (admin=disable in ed-eport)
• VCGs
On VCGs, local signal failure is declared when the VCG is failed or transitions into
AUTO state (because all cross-connections have been removed).
Wave Division Multiplexing in Alcatel-Lucent 1665 DMX shelves (WDMX)
WDMX is the name of the family of features that adds metro WDM capabilities to the
Alcatel-Lucent 1665 DMX product line. For additional details see,
“WDMX optical multiplexing network models” (p. 3-51) .
LNW910 aggregator applications
The LNW910 can be provisioned to support several aggregation application.
VCG aggregator application (EoS)
• One-to-many mapping between the 10GbE face-plate port and 64 VCGs
• Each VCG can have at most 1 user-provisionable VCG.
• Bridging/switching based on the VLAN.

In-service PTM upgrades
Alcatel-Lucent 1665 DMX supports in-service, per port upgrades of the OC-3, OC-12,
OC-48 PTMs on the multi-port, multi-rate LNW82 and LNW55 circuit packs.
In-service electrical upgrade from low to high-density DS1/DS3 circuit packs
Alcatel-Lucent 1665 DMX supports an in-service electrical upgrade on the High-Capacity shelf, enabling you to increase DS1/DS3 capacity without affecting service. There is an outage of 100 to 200 milliseconds when upgrading DS1 circuit packs. By upgrading the
28-port LNW7 to the 56-port LNW8 or LNW801, the total DS1 capacity is increased from 112 to 224 DS1 interfaces per shelf.
By upgrading the 12-port LNW16 to the 48-port LNW19B/20, the total DS3/EC1 capacity is increased from 48 to 192. Electrical in-service upgrades can be performed on shelves hosting a mix of DS1 and DS3/EC1 circuit packs without affecting service. The
Alcatel-Lucent 1665 DMX High-Capacity shelf is required when using high-density
DS1/DS3 circuit packs.
The LNW16, LNW18, LNW19/19B, can be upgraded in-service to the LNW20.
LNW70 to LNW170 circuit pack upgrade
Alcatel-Lucent 1665 DMX supports upgrading an unprotected LNW70 (DA'd January
2010) circuit pack to an LNW170 circuit pack in the same slot. Since the LNW70 circuit pack cannot be protected, this is not an in-service upgrade. However, this upgrade can be performed without removing cross-connections or other provisioning. The LNW170 circuit pack supports all the functionality of the LNW70 circuit pack and adds equipment protection.
Networking capabilities
Overview
This section briefly describes the major networking capabilities supported by
Alcatel-Lucent 1665 DMX.
Multicast Ethernet packets
Alcatel-Lucent 1665 DMX supports multicast Ethernet packets. A multicast packet is identified by the first bit in the MAC destination address. Such a MAC address will never appear as a source address, and so multicast destination addresses (TIDs) are not learned.
Since unknown destination addresses are treated as broadcast, multicast packets/frames are sent to ALL ports in the VLAN (IEEE 802.1Q) or Transparent LAN (customer/port tag) for that packet.

SAN networking via Alcatel-Lucent 1665 DMX
With the LNW73/73C, Alcatel-Lucent 1665 DMX supports native SAN interfaces integrated into the Alcatel-Lucent 1665 DMX shelf. The LNW73/73C is a Storage Area
Networking (SAN) interface card designed to facilitate SAN distance extensions via the use of GFP-T (G.7041) to encapsulate SAN traffic and transport it over SONET networks. It utilizes PTM optics to provide the option of FICON, ESCON, or
Fibre-channel interfaces natively on the Alcatel-Lucent 1665 DMX shelf. Each pack must be equipped with only one type of PTM (either FICON/FC or ESCON) and can be housed in Slot A1, B1, C1, D1, or G1. The LNW73/73C can operate at 1 Gbps or 2 Gbps.
When the pack is operating at 2 Gbps only every other port may be used. So, the total number of SAN interfaces on an Alcatel-Lucent 1665 DMX shelf is 20 when the
LNW73/73C is operating at 1G FC/FICON or ESCON, and 10 when it is set to 2G
FC/FICON.
For information about Alcatel-Lucent 1665 DMX interworking as certified by EMC eLab
Testing, see
“EMC certification” (p. A-91) .
Data compression for SAN traffic
The implementation of SAN compression enables a high throughput of up to two full-line rate FC-2G interfaces in a single pack.
Data compression is supported on LNW73C SAN packs. The LNW73C is able to compress asynchronous Fibre Channel traffic and conserve up to 50% of bandwidth versus uncompressed asynchronous FC traffic in typical applications.
Compression for asynchronous FC traffic is pre-standard and will be standardized by
FC-BB-4.
Fast spanning tree/ IEEE802.1w rapid re-configuration
Ethernet requires a network with a tree structure in order to work effectively. Ethernet bridges and switches build tables that define the paths to specific devices. A MAC bridge, for example, will have a filtering database that defines where to send any packets addressed to a specific MAC within the network. The tables are built based on input from devices within the network. Alcatel-Lucent 1665 DMX supports an improved/faster spanning tree algorithm, documented in IEEE 802.1w Rapid Re-configuration.
LNW170 support spanning tree on LAN ports in addition to VCG ports.
If there is a loop in the network, that is, if there is more than one way to get to a destination device, two problems can result:
Frames may be duplicated in the network.
• That is, the same frame may be sent to a node via two different paths.

....................................................................................................................................................................................................................................
The address information is changed as packets from that device are received across different paths. In a meshed network, the re-configuration of the filtering database can begin to use up all the network resources, so that little bandwidth is left for data traffic.
The spanning tree accomplishes two important functions:
• It removes loops from the bridged network
• It allows Ethernet layer re-configuration if a link fails.
Important! Alcatel-Lucent 1665 DMX has been designed with multi-vendor interoperability in mind. As many vendors' equipment (including legacy equipment) may not be able to use IEEE802.1w, Alcatel-Lucent 1665 DMX can automatically fall back on IEEE802.1d in the event that other NEs in the network are running standard spanning tree protocol. However Alcatel-Lucent 1665 DMX employs IEEE 802.1w as a default spanning tree protocol.
Rapid spanning tree (RSTP) maintenance enhancements for LNW170 circuit packs
The RSTP maintenance enhancements for the LNW170 circuit packs include the following:
• New performance monitoring counters for VCG and LAN ports or Link Aggregation
Groups (LAGs) to record spanning tree modification status
• Spanning tree group Automatic Lock parameter to disable a port which is unstable or rapidly reconfiguring. When the Automatic Lock parameter is enabled and any port in the Spanning Tree Group experiences a threshold-crossing alert (TCA) on the spanning tree state counter, the port is moved to the disabled-failure state preventing traffic flow until released.
Link aggregation
Link aggregation can be used to enable hitless bandwidth increases and both facility and equipment protection on LNW170 or LNW910 LAN ports.
Alcatel-Lucent 1665 DMX supports link aggregation on any two LNW170 LAN ports of the same rate (i.e. 100 or 100 Mbps) operating in switched mode. With the LNW170, the ports can be on the same or different LNW170 packs in an equipment-protected pair.
The LNW910 supports load-balanced LAG or active/standby LAG. If the LNW910 is unprotected, LAG is supported on all FE or GbE ports. If the LNW910 is protected,
LAGs are created automatically for all FE/GbE ports and can also be provisioned for the
10GbE port.
Ordinarily, multiple Ethernet links between two bridges form loops (unless a spanning tree blocks all but one) so they can't be used to increase bandwidth. Link Aggregation causes defined groups of links to be treated as a single logical link, making multiple LAN ports appear as one. In this way, Bandwidth can be increased without requiring an upgrade to a higher rate link.

Link aggregation can also remove failed links automatically, thereby providing a means of facility protection. More links than are needed can be added to the group and each is active until it fails (similar to utilizing LCAS protection for SONET). When two links are on different packs they can provide both, facility and equipment protection. In
Active/Standby LAG, one link of the LAG is designated as the protection link and the other is the working link. Only the working link carries MAC client traffic when none of the links fails. When the working link fails, the traffic switches to the protection link. The protection switching is bi-directional and revertive.
MAC address locking
Alcatel-Lucent 1665 DMX allows MAC locking on the LNW170. MAC locking prevents unauthorized users from gaining access to the network through an Ethernet port, thereby providing a level of security against intrusion attempts. MAC locking restricts access to a bridged Ethernet network by requiring that the source address of traffic entering a locked port be registered with that port. Any number of ports, LANs, VCG, or link aggregation groups (LAGs) can be locked. Alcatel-Lucent 1665 DMX permits registering of multiple addresses with a single entity.
True 0x1 operation for optical ports on LNW74 10/100T/F circuit packs
Series 1:2 or higher LNW74 circuit packs are supported in both slots of the same function/growth group in systems equipped with VLF circuit packs in the Main slots provided there are no loopbacks provisioned on the electrical ports or cross-connections provisioned on the VCG tributaries of any of the electrical ports. The LNW74 circuit pack supports user-provisionable Ethernet port mode configurations that allow true 0x1 optical operation. When operating in the true 0x1 configuration, the optical LAN ports and their associated VCGs/tributaries are fully operational while all operations on the electrical
LAN ports and their associated VCGs/tributaries are denied.
Additional Ethernet features (LNW74/87/170/910)
Many hardware and software-based features require the use of the LNW74. LNW87,
LNW170, and LNW910 circuit packs. The features with a circuit pack listed in parenthesis are available only with the use of the indicated pack.
• Committed and Peak rate controls (CIR and PIR) (LNW170)
• 4 classes of services (LNW170)
• 4xGbE density with PTM optics (LNW170)
• Larger MAC tables (LNW170)

QoS on EoS VCGs
Quality of service (QoS) on Ethernet over SONET (EoS) VCGs is designed to enable aggregation of diverse data streams in multiple topologies amongst LNW170 circuit packs. These topologies include packet rings, hub-and-spoke with LNW170 at the hub, and hybrid ring/hub-and-spoke with LNW170 at the hub.
QoS on EoS VCGs functions by giving EoS VCG ports the same classification options for incoming packets, rate control capabilities for Ethernet services (PIR, CIR), queuing/scheduling capabilities for outgoing, and the same packet transformation functions as on 802.3 LAN ports.
1 Mbps rate limiting
Alcatel-Lucent 1665 DMX supports rate control at the level of 1 Mbps for Ethernet interfaces. This means that Alcatel-Lucent 1665 DMX can automatically establish
Ethernet transmission channels to fit the need of the user upon connection. For each connection, the Alcatel-Lucent 1665 DMX will create a virtual channel of the appropriate size (in 1 Mbps intervals) to facilitate the desired Service Level Agreement (SLA). Rate limiting at the 1Mbps level provides a transmission ceiling for highly efficient allocation of shared bandwidth for data communications.
Ethernet interworking with DDM-2000
To facilitate affordable and more immediate delivery of Ethernet services on SONET networks, Alcatel-Lucent 1665 DMX now interworks with new Ethernet circuit packs available for the DDM-2000.
DDM-2000 now supports a circuit pack providing one 100BASE-LX (100 Mbps p/s) and four 10/100BASE-T ports with data transport at the rate of 10/100 Mbps using standard
Ethernet switching (IEEE 802.1), standard encapsulation according to ITU G.7041 for
Generic Framing Procedure (GFP), ITU G.707 for Virtual Concatenation (VCAT). The
DDM-2000 can transmit Ethernet signals across spans as long as 100 meters. The

DDM-2000 circuit pack is designed specifically to support Fast Ethernet Private Line applications. Each circuit pack can support 4 private lines. The pack supports VT1.5,
STS-1, and STS-3c cross-connections.
The DDM-2000 circuit pack can interwork with the LNW74 and LNW87 circuit packs.
Alcatel-Lucent 1665 DMX/Alcatel-Lucent 1675 LambdaUnite MSS bay configuration
The compact size of the Alcatel-Lucent 1665 DMX allows you to place two
Alcatel-Lucent 1665 DMX shelves and one Alcatel-Lucent 1675 LambdaUnite MSS in the same bay. As the needs of an access site grow to the point where equipment is required to hub more than 6 OC-48 rings, it becomes advantageous to upgrade an
Alcatel-Lucent 1665 DMX shelf to an Alcatel-Lucent 1675 LambdaUnite MSS. The
Short Reach (SR) OC-48 and OC-192 optics supported by the Alcatel-Lucent 1665 DMX are designed for such an application. Once the Alcatel-Lucent 1675 LambdaUnite MSS is installed as the hub-node, the Alcatel-Lucent 1675 LambdaUnite MSS node can hub 64
OC-48 rings or 16 OC-192 rings while simultaneously using the original Alcatel-Lucent
1665 DMX as a drop node or mini-DCS.
1+1 protection switching
Alcatel-Lucent 1665 DMX supports revertive and non-revertive unidirectional and bidirectional protection switching for all OC-n interfaces.
Beginning in Release 9.0, you can change 1+1 protection group from unidirectional 1+1 to bidirectional 1+1 in-service without deleting cross-connections.
High-speed VT1.5 granularity
VT1.5 granularity is provided across any 12 STS-1 signals within the OC-12 high-speed
OLIUs (LNW48, LNW50, LNW203). VT1.5 granularity is provided across 48 STS-1 signals within the OC-48 OLIUs (LNW27, LNW29, LNW76, LNW202). VT1.5
granularity is provided across 192 STS-1 signals within the OC-192 OLIUs (LNW56,
LNW58, and LNW502).
On VLF mains, the available VT bandwidth is not pre-allocated to high-speed and/or low-speed interfaces. Instead, both high- and low-speed interfaces have access to any available STS-1 connection to the VT fabric. For the LNW59 and LNW504, 30G of VT bandwidth is shared by the local high-speed and low-speed interfaces. For the LNW82,
10G of VT bandwidth is shared by the local high-speed and low-speed interfaces.
VT1.5 granularity is provided across 96 STS-1s on the LNW80 (Main Switch Pack).
For the VT granularity of the tributary (low-speed) packs, see
“Optical, tributary interface circuit packs” (p. 2-5) .

Loopbacks
Terminal loopbacks are used during installation and maintenance procedures to test the integrity of near and far-end interfaces as well as fibers and system circuitry. Facility loopbacks are used to test the integrity of the customer to provider network link by looping the signals back at the far end and comparing counts of sent and received frames.
Terminal
Alcatel-Lucent 1665 DMX supports terminal loopbacks on:
• All OC-3/12/48/192 high-speed (network side) interfaces
• All OC-3/12/48/192 low-speed (tributary side) interfaces
• DS1, E1 and DS3 interfaces
• All Ethernet interfaces, both optical and electrical
Facility
Alcatel-Lucent 1665 DMX supports facility loopbacks on:
• All OC-3/12/48/192 high-speed (network side) interfaces
• All OC-3/12/48/192 low-speed (tributary side) interfaces
• DS1, E1 and DS3 interfaces
• Optical and electrical interfaces of the LNW78 and LNW170 packs.
State check before loopback
Beginning in Release 9.1,
ENT-SYS
supports a new parameter, loopback port check
(lpbk_port_ck). The parameter controls how loopbacks are handled for PDH, EC1 and
Ethernet ports based on the state of those ports.
Test access
Test access, a traditional DCS function, allows the user visibility into any DS1/DS3 signal in the network. Test access aids users in turning up connections and in identifying faults in existing service connections.
Alcatel-Lucent 1665 DMX supports two different types of test access. The non-intrusive method simply taps the channel as it passes through the system and routes it to an external testing device. The more intrusive mode splits the VT1.5 or STS-1 from the incoming signal and sends it to an external testing device. Test access facilitates Alcatel-Lucent
1665 DMX functioning in a DCS application.
PRBS generation/detection
Test access using PRBS generation/detection via the internal test head on the VLF Main allows the user to test network, NE, and facility performance/integrity without an external test head. The VLF Mains contain an internal test head that can generate and detect errors in Pseudo Random Bit Sequences (PRBSs). This capability is not meant to wholly eliminate the use of external equipment for tests, but can be used for expediency, less

complicated tests, and where non-manual set-up is advantageous. PRBS enabled test access involves initiating test access, inserting a test signal (i.e. a PRBS) generated internal to the NE, and/or monitoring a received test signal internal to the NE. PRBS generation/detection is supported on STS1, STS3c, and VT1.5 tributaries.
Alcatel-Lucent 1665 DMX allows up to 12 test access sessions at a time and for a mix of test access sessions that specify tatrib(s) and test access sessions to the internal test head within the 12 allowed sessions. The generators and detectors are separately allocated.
The internal test head hardware supports signal generation on up to 12 STS1s, and signal detection on up to 12 STS1s. Internal VT1.5 test access uses one of available STS1s and multiple internal VT test access sessions use the same STS1. Internal VT test access count as the available access sessions even though they are inside the STS-1 Internal test access is supported on STS3c signals; requests using the tatrib parameter(s) are denied. When a generator or detector is allocated to an STS3c session, it uses 3 of the 12-STS1 capacity, and that 3 generators or detectors on the STS3c boundary must be available.
SS bits per circuit pack or port
By default Alcatel-Lucent 1665 DMX transmits 00 in the outgoing SS pointer bits for compatibility with SONET interfaces. Alcatel-Lucent 1665 DMX provides the ability to set the outgoing SS bits to 10 on an optical pack basis for compatibility with older SDH equipment. Alcatel-Lucent 1665 DMX ignores incoming SS bits regardless of the outgoing SS bit provisioning. Most SONET equipment ignores SS bits. Alcatel-Lucent
1665 DMX is provisionable to support SS bits on a per pack basis. This prevents LOP defects and allows SONET/SDH interworking.
The following circuit packs can be provisioned for 00 or 10 SS bits on a per port basis:
• LNW55
• LNW59
• LNW62
• LNW82
• LNW504
• LNW603
Starting in Release 10.0, SS bit mismatches may be alarmed. The user can configure the
"inc. STSN SS Bit Mismatch" alarm to be reported when SS bits received do not match
SS bits transmitted.
Automatic ring discovery for BLSR interworking
Alcatel-Lucent 1665 DMX supports automatic ring discovery to better facilitate BLSR interworking with Alcatel-Lucent 1675 LambdaUnite MSS, FT-2000, WaveStar

Nonpreemptive unprotected traffic
Alcatel-Lucent 1665 DMX allows the manual provisioning of nonpreemptive unprotected traffic (NUT) for multi-point Ethernet and 0x1 cross-connections on service tributaries.
Though this traffic is unprotected, its transmission priority will not be preempted by other service or protection traffic.
E-NNI control plane connections
E-NNI control plane connections are supported from a single-node access domain to an
I-NNI capable edge node of a core domain. Alcatel-Lucent 1665 DMX or Alcatel-Lucent
1665 DMXtend NEs can serve as single-node domain edge nodes and Alcatel-Lucent
1675 LambdaUnite MSS or other vendors’ NEs can serve as the core domain nodes. The transport topology for the E-NNI is SONET linear. Unprotected 0x1 connections and line
1+1 protection are supported.
This capability is supported for Alcatel-Lucent 1665 DMX equipped with LNW59,
LNW82, or LNW504 Main circuit packs. When VLF Main circuit packs are installed,
LNW62 and LNW55 OLIUs can be installed in the shelf, and can support this capability on their low-speed interfaces. For additional information, see
“Control plane E-NNI interface” (p. 3-68) .
Cross-connection types
Allowable cross-connections
This section highlights some of the cross-connections types supported by Alcatel-Lucent
1665 DMX. For an in depth look at all cross-connections supported by the Alcatel-Lucent
1665 DMX, see
in
Chapter 6, “System planning and engineering”
of this document.
Atomic cross-connections
Alcatel-Lucent 1665 DMX employs atomic cross-connections for all cross-connect provisioning. Atomic cross-connections are one-way cross-connections between logical ring channels which can be set up and taken down by a single command, and which cannot be broken down into smaller parts. Logical ring channels are the tributaries of a port or port protection group used for transmission in the absence of any line or equipment protection.

Hairpinning cross-connections
Low-speed tributary traffic is routed into the system and back out without being placed on the high-speed (OC-12, OC-48 or OC-192) interfaces. With a VLF Main pack
(LNW59/LNW82/LNW504), all cross-connections use the switch fabric located on these packs. Any switch fabrics located on low-speed, tributary packs are disabled when VLF
Mains are used.
With the VLF Mains, Alcatel-Lucent 1665 DMX can cross-connect any input on a circuit pack in a function or growth slot to any output on a circuit pack in the same or different function or growth slot. Both slots in a function group can be provisioned independently for working traffic, whether they are the same or different packs. Certain restrictions apply, see
“Very large fabric (VLF) engineering rules” (p. 6-15)
for more information.
These flexible cross-connect capabilities allow you to use a combination of add/drop and hairpinning of compatible payloads through a variety of interfaces. You can bring traffic in from one remote site and cross-connect it at the VT1.5, STS-1, STS-3c, STS-12c,
STS-48c, or STS-192c level back out to other remote sites without consuming any capacity on the ring/line interface.
If hairpinning cross-connections are being provisioned between any interface and a 0x1 unprotected interface, 1-way cross-connections must be used. 1-waypr cross-connections are not allowed in 0x1 unprotected scenarios.
Bridge and roll cross-connections
Bridge and roll cross-connections are coordinated activity between two NEs designed to move traffic from one facility to another, affecting service by a maximum of 10 milliseconds.
Bridged cross-connections
Bridging of an existing cross-connection consists of adding a one-way cross-connection with the same input tributary as that of an existing cross-connection, resulting in a 1x2 multicast from an input tributary to two output tributaries. Alcatel-Lucent 1665 DMX supports bridging for each of the supported SONET cross-connection rates. You can bridge any existing cross-connection to a second output port without impairing the existing signal. Conversely, either half of a bridged signal can be taken down without impairing the remaining cross-connected signal.
Rolling a bridged cross-connection
Alcatel-Lucent 1665 DMX provides the capability to change the location or source of the input tributary of a given cross-connection. Alcatel-Lucent 1665 DMX supports facility rolling for all supported signal rates as follows:
• Disconnection of the circuit cross-connecting input tributary to output tributary
• Cross-connection of either a new input tributary to the corresponding input tributary

Unprotected cross-connections
With unprotected cross-connections on a UPSR Alcatel-Lucent 1665 DMX does not select the best signal from both rotations of a UPSR. Instead, traffic is added and dropped
(locked) from one rotation of the ring only (provisionable). The main advantage of locked
VT or DS3 cross-connections is the lack of UPSR switching which results in the ability to reuse time slots around a UPSR.
Alcatel-Lucent 1665 DMX has the ability to mix unprotected (locked), protected
(unlocked), and pass-through VT1.5s within the same STS-1, and to allow both rotations of a ring to be used simultaneously.
Unprotected cross-connections are also supported to Ethernet VCGs.
Multi-point (Ethernet only)
The data specific multi-point cross-connect is a bidirectional cross-connection between two STS-1 Virtual Concatenation Groups (VCGs) on 100BASE-T or 1000BASE-X ports to two different ring interfaces.
Pipe-mode (adaptive-rate) cross-connections
Pipe mode is a fault monitoring and performance monitoring feature whereby each automatically adapts to changes in the constituent payload structure of a provisioned
STS-n rate cross-connection. Fault and PM are based on the payloads carried within a cross-connection rather than the cross-connection rate. Path protection switching continues to operate at the provisioned cross-connect rate.

Operations features
Overview
Alcatel-Lucent 1665 DMX supports a three tiered operations philosophy consisting of the system controller functions and visual indicators, local interface to the shelf via serial ports and LAN ports and remote OS interface over a Data Communications Channel. The following features highlight a few of the key operations features that provide effective operation and maintenance of the system.
WaveStar
®
CIT with GUI
WaveStar
®
CIT manages the Alcatel-Lucent 1665 DMX system through the TL1/CIT port, providing TL1 messaging, software download, and full operations and provisioning capability via a Graphic User Interface (GUI) or TL1 cut-through. WaveStar
®
CIT can run a full-featured GUI or TL1 scripts. Using the GUI, a crafts person can access all
Alcatel-Lucent 1665 DMX software functions and context-sensitive help. The TL1 cut-through, also known as the TL1 Translation Device (T-TD), is a flexible TL1 interface that supports full TL1 management through TCP/IP or RS-232 interfaces.
WaveStar
®
CIT is not used to download release software to the system (the PC is used, but not the CIT software). Release software can be copied to other NEs remotely, provided the initial download of Alcatel-Lucent 1665 DMX release software has occurred on each system.
TL1 management
The TL1 cut-through interface provides full TL1 management via the Serial and IAO
LAN interfaces.
TL1 management via TCP/IP
TL1 message exchange is supported over TCP/IP via IAO LAN, OSI LAN, and
WaveStar
®
CIT interfaces. IAO LAN supports TCP/IP protocol and OSI protocol. These provide a communication link from an Alcatel-Lucent 1665 DMX to a local node that may serve as a gateway to the network.
Beginning in Release 9.1, TL1 command entry in TL1 cut-through mode is simplified.
The last TID entered is remembered and used in all subsequent commands in which a TID is not specified until a different TID is entered.
Integrated TCP/IP management interface
Alcatel-Lucent 1665 DMX supports two types of IP Access. In one case, Alcatel-Lucent
1665 DMXcan serve as a TL1 Translation Device (T-TD) by being a gateway network element that allows a OMS and/or WaveStar

elements (NEs) on an OSI network through an IP access network. In the second instance, the Alcatel-Lucent 1665 DMX can functionally encapsulate IP packets within OSI packets to be transmitted through the OSI network to the proper NE. This capability is called IP tunneling.
TL1 translation
Alcatel-Lucent 1665 DMX can copy the application information within an IP packet into an OSI packet. Thus, all IP protocol information is lost. This translation is performed at the application layer. Separate gateways can be provided by a single Alcatel-Lucent 1665
DMX.
IP tunneling
IP tunneling allows for file transfer through an IP access network. IP tunneling is used to perform end-to-end FTP through the OSI portion of the IP access network. In this instance the Alcatel-Lucent 1665 DMX serves as a gateway network element (GNE) that encapsulates an IP packet within an OSI packet. When the final destination of the file is reached, the IP packet is removed from within the OSI packet and processed by the
TCP/IP stack. Thus, IP tunneling allows an OMS and/or CIT to reach NEs in an OSI based DCN network with FTP over IP. In this case, the end points of the IP tunnel are the actual terminating points for the IP traffic.
Proxy ARP
In normal ARP usage for an Ethernet LAN, the sending system broadcasts an ARP request on the physical LAN. The ARP request contains the target IP address and asks the system with this IP address to respond with its physical Ethernet address. All systems on the LAN receive the request, but only the system which recognizes the target IP address as its own will send a point-to-point ARP reply to the sending system. The broadcast ARP request on a physical LAN only reaches systems which are attached to this physical LAN.
If the sending system and the target system are on different physical networks, the target system will not receive the ARP request and thus can not respond to it. Proxy ARP lets a system, called ARP subnet gateway, answer ARP requests received from one of its physical (LAN) networks for a target system which is not attached to this physical network.
To allow SNMP manager/NTP server located in the IP-based access Data Communication
Network (DCN) to communicate with NEs located in the OSI-based DCN,
Alcatel-Lucent 1665 DMX supports IP tunneling solution to encapsulate and route IP packets over OSI-based embedded DCN. The provisioning of static routes on the external router(s) is required to route the IP packets from the access DCN to the embedded DCN.
The Proxy ARP support on the Gateway Network Element (GNE) will eliminate this need of static routes on the external router(s).

ARP subnet gateway
The ARP Subnet Gateway implementation adheres to RFC1027 which states that, if the
IP networks of the source and target hosts of an ARP request are different, an ARP subnet gateway implementation should not reply to the request. This is to prevent the ARP subnet gateway from being used to reach foreign IP networks and possibly bypass security checks provided by IP gateways.
Because of this RFC requirement, the IP addresses of both the GNE and RNE must be in the same network with respect to network class (A, B and C). For example, if the GNE has a class C IP address 192.168.170.1, the RNE must have an IP address in the same
Class C network, in the form 192.168.170.x. For proxy ARP to function properly, the
Remote NE IP address must be in the same subnet as the IP address of the router, as specified by the network mask on the router. Otherwise, the router will not send the ARP request to the appropriate LAN port, and will instead route the packet through its default
IP gateway into the IP cloud.
However, the IP address of the remote NE should not be in the same subnet as the IP address of the GNE, from either the GNEs network mask perspective or the RNEs network mask perspective. An easy way to achieve this on the RNE is to assign a 32-bit network mask to all RNEs.
FTP/FTAM gateway for remote software download
Also referred to as FTTD (File Transfer Translation Device), the FTTD allows
Alcatel-Lucent 1665 DMX to function as a Gateway Network Element (GNE) that can facilitate the download of files located at FTP servers to remote NEs connected to the
Alcatel-Lucent 1665 DMX.
SSH File Transfer Protocol (SFTP)
Beginning in 9.0, the LNW2 SYSCTL circuit pack supports SSH File Transfer Protocol
(SFTP) for software download, database backup, and database restoration. SSH File
Transfer Protocol (SFTP) is a new protocol defined by IETF which runs over a secure
SSH channel and provides secure file transfers. Network configurations, user names, passwords, FTP commands and transferred files are protected.
Note: You must have IP connectivity between your NE and your SFTP server, and your NE must have a defined IP address. The WaveStar
®
CIT is not SSH FTP (SFTP) server. You must have access to an SSH FTP server to use this feature.
Software download over DCC
This feature enables software (upgrade) to be downloaded to remote NEs from a central office site via the data communications channel (DCC).

OSI associations and TCP/IP connections
When used as a GNE, Alcatel-Lucent 1665 DMX supports a total of 300 OSI associations
(logins). Each TCP/IP (or Telnet) connection can support 300 associations. The
Alcatel-Lucent 1665 DMX GNE supports up to 20 TCP/IP connections. The combined number of OSI associations on all TCP/IP sessions cannot exceed 300.
OSI seven-layer protocol stack
This feature provides interworking using the Open Systems Interconnection (OSI) seven-layer protocol stack over the data communications channel (DCC). The OSI seven-layer protocol stack refers to the OSI reference model, a logical structure for network operations standardized by the International Standards Organization (ISO).
Maximum number of OSI nodes
Alcatel-Lucent 1665 DMX can support a total of 250 NEs per Level 1 area.
Remote NE status
This feature partitions a subnetwork into maintenance domains (alarm groups). An Alarm
Group is a set of NEs that share status information. Alarm groups can be nodes in a ring or any other logical grouping such as a maintenance or geographical group. Each Level 1 area can be identified as a separate Alarm Group, as long as it does not exceed 50 nodes.
You must provision one NE in an Alarm Group as an alarm gateway NE (AGNE) to support office alarms and a summary alarm information of remote NEs in the local alarm report. More than one AGNE can be provisioned per alarm group, but this is not recommended.
TARP
Alcatel-Lucent 1665 DMX is compatible with any other-vendor NEs that support Target
ID Address Resolution Protocol (TARP), OSI, IAO LAN, and TL1 as specified in
Telcordia
®
GR-253.
SONET
Many of the traditional SONET maintenance, provisioning, operations, control, and synchronization features are included in the Alcatel-Lucent 1665 DMX. The flexible
SONET standard provides a formidable foundation for Alcatel-Lucent 1665 DMX to build upon.
Security
Security features include 1–999 day password aging, customized login proprietary message, and 150 users.

Remote Authentication Dial In User Service (RADIUS) authentication for user logins
When the network element is provisioned to use RADIUS authentication, any user
TL1/CLI/Web GUI login attempt triggers the network element, if the maximum number of logins is not reached, to query the designated RADIUS server(s) and act on the response.
Performance monitoring
Performance monitoring (PM) data is reported on the VT1.5, VC12, STS-1, STS-3c,
STS-12c, STS-48c, STS-192c, DS1, E1, DS3, EC-1, Ethernet (LAN and VCG ports),
SAN, OC-3, OC-12, OC-48, and OC-192 levels.
Alarm severity assignment profiles (ASAPs)
Alcatel-Lucent 1665 DMX supports adjustable ASAPs. With ASAPs, alarms are grouped into categories called "Profile Types". Each Profile Type can have multiple views
(ASAPs). These views include the default view and various user created/provisioned profiles. Each ASAP within a profile type has the same alarms, but alarm severity levels are user provisionable. The user can then assign ASAPs to entities within the shelf.
ASAPs make it possible to assign different alarm severity levels for all alarms. This feature also allows the user to assign different alarm severity levels for the same probable cause to different entities within the shelf. Once alarm severity levels are set, the user can assign the same level to different entities without re-provisioning the level itself.
These capabilities give the user greater control over alarm reporting.
Improved circuit pack failure alarms
Improved circuit pack failure alarms are supported to identify circuit packs that contribute to the failure of another circuit pack. The existing circuit pack failure alarms are augmented by reporting the
CP contributing to a pack failure alarm for all circuit packs that are contributing to the circuit pack failure. The severity level is provisionable using alarm severity assignment profiles.
TIRKS/NMA/transport compatibility
Alcatel-Lucent 1665 DMX is supported by Telcordia
®
OSs: TIRKS, NMA, and
Transport.
Multivendor operations interworking

OMS operations support
Alcatel-Lucent 1665 DMX supports operations via OMS and 1340INC.
Support of Simple Network Management Protocol
Alcatel-Lucent 1665 DMX supports Simple Network Management Protocol (SNMP). It is a language protocol for communications between network elements and management systems. As such, it includes verbs (commands), nouns (objects) and a structure and rules
(protocol). It has a degree of standardization that is much greater than TL1, particularly with respect to the commands and objects and it’s intended to be a very simple UDP/IP based protocol, with few commands, that is easy to implement at low cost, for monitoring and managing low cost bridges and routers.
Alcatel-Lucent 1665 DMX supports a maximum of 10 enabled SNMP Users for request functionality and a maximum of 10 enabled SNMP Users for receiving traps. However, the NE only supports 16 users total.
The three basic SNMP components are:
• The protocol defines the rules and specifications for exchanging information between a manager and an agent. This includes the detailed specification of the SNMP commands, messages and the command/message PDUs (packet data units) as well as the way security is handled.
• Management Information Base (MIB) is the set of managed objects on which the
SNMP commands operate. These managed objects can be provisionable or status parameters or alarms and events entities.
SNMP applications use public and private Management Information Bases (MIBs) that define the equipment and Ethernet/SONET/SDH/PDH performance monitoring parameters (objects) and alarm/event messages (traps) that can be communicated.
Public MIBs are specified in standards. Private MIBs are unique to . The public and private MIBs are stored on the PC that is running the SNMP application.
• Structure of Management Information (SMI) is the rules for the definition of managed objects, including the object name, the Object Identifier (OID), and the object syntax, which in SNMP uses ASN.1 standard encoding.

Alcatel-Lucent 1665 DMX provides SNMP support of certain reports and traps for all
Ethernet interfaces. For more information, see
“SNMP parameters and traps” (p. 5-112)
in
Chapter 5, “Operations, administration, maintenance, and provisioning” .
Alcatel-Lucent 1665 DMX supports SNMP on DS1/E1 and DS3/EC-1 interfaces. SNMP support of these TDM interfaces includes traps and performance monitoring parameters.
Beginning in 9.0, the Alcatel-Lucent 1665 DMX circuit packs independently support
SNMPv3 protocol to monitor individual circuit pack operation. SNMPv3 was developed to provide a higher level of security through the use of encryption.
SNMPv3
SNMPv3 provides secure access by a combination of authenticating and encrypting packets over the network. The
SNMPv3 security features are:
• Message integrity - ensuring that a packet has not been tampered with in-transient.
• Authentication - Determining that the message is from a valid source.
• Encryption - Scrambling the contents of a packet to prevent it from being seen by an unauthorized source.
SNMPv3 control is through a View BasedAccess Control model (VACM). In VACM, users are assigned to groups which define and specify:
• The SNMP version, (v1, v2c or v3) specifies the SNMP version provides the means for allowing some users to access the NE via the earlier SNMP versions with minimum security while allowing other users to access the NE via the more secure
V3. While the VACM groups are user provisionable starting with the phase 2 implementation, it would be expected that write access will generally be allowed only to VACM groups that specify SNMPv3.
• The access policy for the users assigned to the group. For example, the SNMP MIBs and objects that can be accessed for reading, writing and creating. The SNMP MIBs and objects are specified in the VACM as a text strings identifying a MIB groups.
• The list of notifications the group’s users can receive. Notifications are also specified in the VACM group as a text strings identifying a MIB groups.

• The security model and security level for the group’s users. SNMPv3 specifies 3 levels of security:
– noAuthNoPriv: without authentication and without privacy — for DMX, this is equivalent to the minimal authentication currently provided for SNMPv2
– authNoPriv: with authentication but without privacy. This level of security uses
MD5 and the Secure Hash Algorithm as keyed hashing algorithms to protect against data modification attacks and to provide data origin authentication and to defend against masquerade attacks
– authPriv: with authentication and with privacy. In addition to secure authentication, this level of security uses the Data Encryption Standard (DES) to encrypt the message content to protect against disclosure.
Synchronization
Synchonization configurations
The OC-3/12/48/192 high-speed circuit packs (as well as LNW80) contain an embedded
Stratum 3 timing generator. This timing generator is used when the Alcatel-Lucent 1665
DMX is configured in a free running mode.
Line timing and external timing are also supported by Alcatel-Lucent 1665 DMX. Line timing is derived from an incoming MAIN or tributary OC-3/12/48/192 line, while external timing is derived from an external timing source. Line timing from tributary optical interfaces is supported. The timing generator also provides a BITS clock output derived from the incoming line signal.
Note: Line timing source cannot be derived from an LNW705 circuit pack.
Timing output
Alcatel-Lucent 1665 DMX can generate a DS1 timing output to time other externally-timed systems. The DS1 output is derived from a line reference.
Alcatel-Lucent 1665 DMX also supports E1 timing output when equipped with a VLF
Main circuit pack.
Important! When the Alcatel-Lucent 1665 DMX is provisioned for SONETSYNC, both input ext timing reference and ext reference output are DS1. When the
Alcatel-Lucent 1665 DMX is provisioned for SDHSYNC, both input ext timing reference and ext reference output are E1.
Synchronization status messages (SSM)
Alcatel-Lucent 1665 DMX uses Synchronization Status Messages (SSMs), transported in the S1 byte of the SONET or SDH overhead. To pass timing status information to different nodes in an access transport network, Alcatel-Lucent 1665 DMX also supports

SSMs in the DS1 or E1 external timing reference inputs and outputs. They contain clock quality labels that allow the NE to select the most suitable synchronization reference from the set of available references. The purpose of the SSMs is to allow the NEs to reconfigure their synchronization references autonomously while avoiding the creation of timing loops.
Line timing from optical tributary packs
Alcatel-Lucent 1665 DMX can derive timing references from any SONET/SDH optical line entering Main, Function Unit, or Growth slots.
All optical circuit packs, except the LNW705 and LNW785, can derive a 6.48 MHz timing signal from an incoming optical line.
Network Time Protocol
Network Time Protocol (NTP) assures accurate synchronization of the Alcatel-Lucent
1665 DMX with reference to radio and/or atomic clocks located on the Internet.

Established network evolution
Overview
Alcatel-Lucent 1665 DMX offers a capacity upgrade from an OC-3 or OC-12 network to an OC-12/48/192 network. Implementing an Alcatel-Lucent 1665 DMX ring at the edge of the network, in combination with pre-existing OC-3 and OC-12 rings, provides increased network capacity and flexibility with the opportunity to interwork with or replace current–Generation access multiplexers.
Description
Alcatel-Lucent 1665 DMX can interwork with existing Alcatel-Lucent and other-vendor
SONET network elements to support all of the applications and topologies described in this section. The figures below show the network evolving from an OC-3/OC-12 network to an OC-48/192 network.

Ethernet Private Line
Overview
Ethernet private lines provide the user the ability to transport frames completely transparently between two Alcatel-Lucent 1665 DMX NEs. No VLAN knowledge or packet-layer provisioning is required by the user in this application. Simple, SONET
STS-1 cross-connect provisioning is all that is required. These Private Line capabilities allow the Alcatel-Lucent 1665 DMX to provide dedicated bandwidth for individual customers and fast SONET-layer restoration in the event of a facility-based failure.
Ethernet Private Line (point-to-point Ethernet) for enterprise LAN transport
Alcatel-Lucent 1665 DMX utilizes standard STS-1 (STS-3(c) can also be used) with virtual concatenation (ITU G.707) to transport 10/100 Mbps or 1000 Mbps Ethernet services over a SONET OC-12/48/192 UPSR/BLSR ring. In this configuration, Ethernet traffic from an end customer may be fed to a core router in the central office (CO), while

Similar to the figure discussed in the previous section, the figure below shows a customer
(Customer 1) with a Private LAN connecting multiple sites. In such applications, multi-point connectivity enables simultaneous connectivity to all sites serviced by the
Private LAN at all times. Ethernet Private LAN links are sized independently and are configured for 802.1q or Transparent VLAN mode. Finally, in multi-point Ethernet applications, the intermediate nodes (the Alcatel-Lucent 1665 DMX at the bottom of the ring in the figure below) provide a simple bridging function, passing-through all Ethernet traffic on the Private LAN. As such, the intermediate nodes do no require Ethernet functionality.

Ethernet rate control services
Overview
Rate-controlled services offer a statistical multiplexing model that makes efficient use of shared bandwidth. Alcatel-Lucent 1665 DMX currently supports two of the primary forms of rate control. The two primary forms of rate control are rate limiting and guaranteed rate services (plus various combinations of both).
Rate limiting is achieved using Peak Information Rate (PIR) provisioning. Guaranteed rate service is achieved using Committed Information Rate (CIR) provisioning. PIR institutes a limit, or "ceiling", of maximum bandwidth to be allocated to a particular customer at any time. CIR, on the other hand, provides a guaranteed minimum, or "floor" throughput even during periods of high congestion. Alcatel-Lucent 1665 DMX provides support of CIR.

Description
The figure above demonstrates the relationship between CIR and PIR services for a single customer's “bursty” data stream. Again, PIR represents the maximum bandwidth a particular customer will be allocated at any time, while CIR is guaranteed minimum bandwidth that insures a constant level of service even during periods of high congestion.
As the figure above suggests, if the maximum bandwidth for a customer (PIR) is exceeded, surplus packets may be dropped. Rate guarantees can be changed in-service and are provisionable at sub-rate levels (1 Mbps).
Policing takes place first in order to ensure that a customer meets the CIR/PIR stipulations of their contract. The priority queuing relative to other customer's traffic then occurs providing another QoS capability.

Application advantage
Rate control provides the capability to offer a maximum "ceiling" throughput at all times
(PIR). It also supports commitments to minimum bandwidth availability (CIR). This combination of CIR and PIR rate control enables Alcatel-Lucent 1665 DMX to both help service providers meet detailed service level agreements (SLAs) and to ensure adequate capacity for end-users at all times. SLAs also can be offered with sub-rate guarantees.
Rate control can enable oversubscription with increased revenue potential. Finally, all
Private Line traffic is protected by time-tested SONET layer protection (1+1, UPSR, and
BLSR).

Hitless bandwidth provisioning with LCAS
....................................................................................................................................................................................................................................
Hitless bandwidth provisioning with LCAS
Overview
Link Capacity Adjustment Scheme (LCAS) enables in-service (or non-service affecting) bandwidth increases/decreases for Ethernet links. LCAS is a two-way protocol, to function it requires a return path for signaling. It works with two-way cross connects or pairs of one-way cross connects on the span.
Description
Alcatel-Lucent 1665 DMX supports standard LCAS per ITU G.7041. Bandwidth changes to Ethernet links are done one span at a time. Without LCAS, provisioning a bandwidth change on the first span of a packet ring takes down Ethernet service around the rest of the ring until the entire ring is set to operate at the same capacity.
With LCAS, planned increases and/or decreases of bandwidth are hitless (that is, they do not affect service). As the figure below illustrates, when capacity changes to each span around the packet ring are provisioned, service is not interrupted. While the span between nodes A&B is set to 15 STS-1s, the remaining spans continue to function at 10 STS-1s.

Application advantages
As the global market for communication services is in continuous flux, both advances in technology and changes in state, regional, and national economies exert various pressures on your network. Accordingly, capacity changes to your network are necessary on a regular basis.
LCAS enables you to meet the challenges of today's market without affecting service.
With LCAS, you are not in danger of violating stringent Enterprise customer SLAs. You can also deploy you SONET network according to long-term growth forecasts, and get the most out of the ability to adjust Private Line and packet ring capacity within your
SONET lines.
Link aggregation
Overview
Alcatel-Lucent 1665 DMX supports link aggregation on an unprotected LNW170 for any two LAN ports of the same rate (i.e. 100 or 1000 Mbps), operating in switched mode.
When a slot pair is equipped with LNW170 circuit packs, provisioning the slot to the protected state sets the packs to be equipment protected and assigns certain corresponding ports on the companion circuit packs to the same fixed link aggregation groups. When the slot is provisioned to the unprotected state, if the NE is equipped with VLF MAINs, the
LNW170 circuit packs are unprotected and the corresponding ports on the companion packs operate independently. If the NE is equipped with non-VLF MAINs, the LNW170 in the slot is unprotected and any circuit pack in the companion slot is alarmed.
Alcatel-Lucent 1665 DMX supports link aggregation on the 10GbE port and FE/GbE ports on the LNW910. When equipment protection is provisioned on the LNW910 packs,
LAG is only supported only on the 10GE port.
Description
Ordinarily, multiple Ethernet links between two bridges form loops (unless a spanning tree blocks all but one) so they can't be used to increase bandwidth. Link Aggregation causes defined groups of links to be treated as a single logical link, making multiple LAN ports appear as one. In this way, Bandwidth may be increased without requiring an upgrade to a higher rate link.
Link aggregation can also remove failed links automatically, thereby providing a means of facility protection. When a link fails, traffic is shifted to the remaining links in that
Link Aggregation Group (LAG). More links than are needed can be added to the group

and each is active until it fails (similar to utilizing LCAS protection for SONET tributaries). When two links are on different packs they can provide both, facility and equipment protection.
Active/Standby LAG
In Active/Standby LAG, one link of the LAG is designated as the protection link and the other is the working link. Only the working link carries MAC client traffic when none of the links fails. When the working link fails, the traffic switches to the protection link. The protection switching is bidirectional and revertive.
Link aggregation example
The figure below depicts link aggregation on two LNW170 LAN ports functioning at
100Mbps. The top portion of the figure shows two ports receiving separate 100 Mbps inbound flows. The bottom portion depicts the same two flows being equally split across the two outbound ports in the LAG. In this example, no failure has occurred and both ports comprising the LAG are in-service.
Traffic entering incoming ports is aggregated into a LAG. While both ports are in-service, outgoing traffic is split between working ports.
Figure 3-10 Link aggregation at 100 Mbps (all ports in-service)
The instance pictured above represents the ideal case, in which there are at least 2 flows, each a maximum of 100Mbps. In this case they can be equally split over the two ports comprising the LAG. The ability to split two or more flows across multiple ports depends on the distribution of MAC or IP addresses used to identify the flows.
Link aggregation employs an algorithm that assigns traffic flows to member ports to prevent mis-ordering. A given flow can be assigned to only one port and cannot be split across multiple ports in the same LAG. To increase flexibility, Alcatel-Lucent 1665 DMX allows a flow to be defined by either a MAC source and destination address pair or an IP

source and address pair. The algorithm uses the XOR of the least significant bits of the address pairs to assign a port/link. Therefore, the actual load balancing achieved depends on the distribution of MAC/IP addresses.
Application advantage
Link Aggregation provides a means of supporting facility protection and bandwidth increases/decreases on LAN ports. Link Aggregation causes defined groups of links to be treated as a single logical link and removes failed links automatically, thereby enabling bandwidth changes and facility protection on 2 paired links comprising a LAG. When the two ports of a LAG are on separate packs, the active-WAN pack (the one selected to send and receive on the SONET network side) is protected against failure by the selection of the second pack. The LNW170 and LNW910 support this combination of facility and equipment protection.
Virtual LAN services
Overview
The Virtual LAN (VLAN) Service application provides a packet-based Ethernet connection via a shared packet over SONET connection.
Description
VLAN Service applications can be utilized by multiple customers over a shared ring for improved bandwidth efficiency. Alcatel-Lucent 1665 DMX uses VLANs and allows bandwidth to be shared among customers. Up to 4093 VLANs can be assigned to guarantee privacy among various customers.
Multiple customers can use the VLAN interconnect (multipoint LAN) capability of

Best effort Ethernet service
Overview
Best effort Ethernet Services is an over-subscription service model that functions without rate control. Ideal for broadband Internet access within a metro area, Best Effort Ethernet
Service enables service providers/carriers to offer an economy-class of service that maximizes revenue potential of a fixed amount of bandwidth.
Description
In the Best Effort service model customers share common bandwidth and are given no quality of service (QoS) or throughput rate guarantees. Thus best effort applications function without rate control services and provide customers with throughput relative to available bandwidth only.
If customers require that their traffic be separated from common network traffic (for security purposes), this can be achieved by VLAN tagging (IEEE 802.1q) or Transparent
VLANs (see the sections above). Traffic in best effort applications may also be prioritized via IEEE 802.1p tags.
Protection in this application is provided by both standard SONET layer switching within the WAN and Rapid Spanning Tree protocol (IEEE 802.1w) in the Ethernet environment.

IPsec Tunnels. These enhanced IP services allow service providers to offer customers state-of-the-art networking capabilities such as network based VPNs, built-in QoS, bullet-proof security, multi-tenant Internet access, voice/data convergence, and other next generation applications.
Description
While Alcatel-Lucent 1665 DMX single-handedly enables such things as voice/data convergence, it is important to state that the majority of the services listed above are supported by various IP Services platforms (Alcatel-Lucent's Access Point
®
Routers, and
Brick Firewall Family for example). The Alcatel-Lucent 1665 DMX, however provides an efficient and crucial link between metro area networks and these IP Services platforms located in the network core.
In the figure below the Alcatel-Lucent 1665 DMX is hosting an OC-48/192 metro ring connected to an OC-12/48 access ring on one end, and the metro core on the other. On the access ring side, Alcatel-Lucent 1665 DMX provides a link to CPE sized multiplexers
(which are in turn connected to routers or firewalls) or directly to IP routers (over
10/100/1000 Mbps Ethernet interfaces).

1000BASE-X, along with electrical 10/100BASE-T and 1000BASE-T ports on one card for data traffic aggregation at the metro edge or data traffic hand-off at the metro core.
Application advantages
Alcatel-Lucent 1665 DMX provides superior Ethernet aggregation and switch capacity with the LNW170. Each LNW170 supports an industry leading, single circuit pack capacity of 2.5Gbps. It supports both optical 100BASE-ZX/LX/FX and
1000BASE-SX/LX/ZX, along with electrical 10/100BASE-T and 1000BASE-T optical ports on the same pack, allowing you to provision the most appropriate and rate-specific data cross-connections for your network. This helps you to get the most out of your investment in both metro edge and data core NEs.
With an array of Ethernet topologies to choose from, Alcatel-Lucent 1665 DMX allows you to deploy the most appropriate network for your customers' needs. Support of industry standard private lines and Packet rings, with both SONET and spanning tree protection schemes, ensures your ability to interwork with CPE networks and provide your customers with the highest level of reliability possible. R5.1 also makes such billable services as CIR and PIR available in structuring Enterprise SLAs. Meeting the reliability requirements of stringent SLAs is easier given R5.1's support of LCAS, which enables hitless bandwidth provisioning.
Alcatel-Lucent 1665 DMX provides all of these capabilities within an industry leading
TDM NE that scales from DS1/E1 to OC-192 in the same, compact unit. This makes
Alcatel-Lucent 1665 DMX capable of aggregating both Ethernet and SONET traffic with the highest levels of speed, security, and sophistication possible.
SAN distance extensions with Alcatel-Lucent 1665 DMX
Overview
With today's increasing regulations and heightened concern with Business Continuity and
Disaster Recovery, both large and small businesses must consider alternate storage architectures for distance extensions. Alcatel-Lucent 1665 DMX can provide a ubiquitous, flexible, highly reliable platform for both TDM and data-based transport, including voice, DSn Private Line, Ethernet, and storage (SAN) traffic.

....................................................................................................................................................................................................................................
Description
When SAN deployments began in corporations and colleges, it was to serve the needs of various, unique departments within a larger organization. The resulting situation, depicted in the figure below, is one of multiple SAN Islands made up of disparate technology with various management and transport requirements.
Figure 3-16 SAN islands today
There are three options available to connect SAN islands: IP, WDM, and SONET. IP is attractive due to its high availability, but it is non-deterministic and prone to packet loss.
This makes IP incapable of providing both the capacity and reliability necessitated by enterprise requirements. WDM is not widely available for enterprises today, but is a good choice for large data center connectivity and those enterprises that require many storage ports.
SONET, on the other hand, is ubiquitously available and accepted as a data transport platform by business customers. It provides the most attractive balance of QoS and capacity for small to large-sized Enterprises running both synchronous (disk mirroring) and asynchronous (data replication/backup) applications. With new technology such as
GFP, VCAT, and LCAS, SAN over SONET enables simple deployment and traffic engineering for carriers, while ensuring efficient transport by way of low overhead byte count and flexible framing. Due to SONET's advanced protection capabilities it can guarantee little or no packet loss for SAN transport. Plus, given Ethernet's incorporation into SONET platforms, SAN management can be easily centralized and performed over
IP. For reliability, capacity, and ease of deployment/management SONET is the clear choice when considering the creation of corporate and campus SAN extensions.
Application advantages
In addition to GFP, VCAT, and LCAS, 1665 products incorporate a full array of SAN interfaces on a single card to enable efficient SAN transport over SONET. The SAN card uses PTM (Pluggable Transmission Module) optics, to provide FICON, ESCON, and
Fibre-channel interfaces. The same card can be used on both the Alcatel-Lucent 1665
DMX and Alcatel-Lucent 1665 DMXtend, enabling rollout of new services from the metro core to edge, where and when they are requested. It can be equipped with four
200Mbps ESCON ports or four 1Gbs, two 2Gbs, or a mix of one 2Gbs and two 1Gbs

In addition to protecting their existing investments in hardware, this approach also enables the continued use of platforms and procedures used to manage their internal LAN. On the SP side, integrated access amounts to enabling converged service offerings with similar advantages. SPs can deliver more revenue generating services without the use of multiple CPEs/CO access devices. This is both an attractive prospect for enterprises, and allows SPs to keep OPEX under control. As
SONET-based platforms, the 1665 Product Family can interoperate with SP management systems and be easily integrated into their network.
Across the board, industry analysts agree that OPEX and CAPEX reductions are the compelling force for upgrading to next–Generation network elements. And with a small footprint, great scalability, and fully integrated multi-service interfaces, Alcatel-Lucent

Functionality via LNW20
Before the LNW20 was introduced, Alcatel-Lucent 1665 DMX could support TransMUX functionality on DS3 signals using the LNW18. It could also support EC-1 signals using the LNW16/19B.
With the LNW20, Alcatel-Lucent 1665 DMX can support DS3, EC-1, and/or TransMUX using a single circuit pack. As the figure shows, it also supports the portless DS3 mode that allows TransMUX functionality without using any of the physical interfaces on the circuit pack (for ports in portless mode).
When a port is provisioned for Portless DS3 operation, a channelized DS3 signal within an STS-1 tributary from a SONET interface on a different circuit pack (OC-n or EC-1) or the same circuit pack (an EC-1 on another port) is terminated and demultiplexed into

constituent DS1 signals. The DS1 signals are encapsulated into VT1.5 signals and cross-connected at the VT-level within the cross-connection fabric on the Main circuit pack to any other interface that supports DS1 signal transport, including a DS1 interface, a channelized DS3 interface, an EC-1 or OC-n interface. This requires two bidirectional backplane STS-1 signals to convert a single (bidirectional) STS-1 channel.
If the Main slots are equipped with Very Large Fabric LNW59, LNW82, or LNW504 circuit packs, portless operation is supported on all ports when the LNW20 circuit pack is installed in any Function/Growth group.
If the Main slots are equipped with large fabric (non-VLF) circuit packs, portless DS3 operation is supported on the odd ports only when the LNW20 circuit pack is installed in any Function/Growth group. The corresponding even port (odd port plus one) is unavailable.
If the Main slots are not equipped with large fabric or very large fabric OLIU circuit packs, portless DS3 operation is not supported and any attempts to provision portless DS3 operation will be denied.
Application advantage
Enhanced TransMUX functionality with the LNW20 enables Alcatel-Lucent 1665 DMX to:
• Upgrade density for TransMUX to 48 ports per pack
• Support DS3, EC-1 and TransMUX on a single pack
• Portless functionality allows Alcatel-Lucent 1665 DMX to cross-connect any channelized DS3 entering the shelf to any port that accepts VT-mapped STS-1s without using the electrical interfaces on the LNW20 itself.
• Groom DS1s for channelized DS3s
• Eliminate the need for separate M-13 MUXs at the DS1 aggregation site
• Pack DS3s with multiple DS1s to use bandwidth back to the network core most efficiently

WDMX optical multiplexing
Overview
Alcatel-Lucent 1665 DMX offers WDM optical transmitters for main optical packs and also offers non-integrated mux/demux, optical amplification and transponders through the
Wavelength Extension Services (WES) portfolio. WDMX is the integration of these types of WDM functions directly on the Alcatel-Lucent 1665 DMX shelf platform. It provides metro transport markets with a state of the art low-cost converged MSPP/MSTP solution for both TDM and WDM. The LNW705 supports this integration on Alcatel-Lucent 1665
DMX.
WDMX comprises feature sets that add the ITU-T Optical Transport Network (OTN) layered structure for WDM within the Alcatel-Lucent 1665 DMX shelf footprint. The optical transport network layered structure consists of optical channel, optical multiplex section and optical transmission section. Pre-existing Alcatel-Lucent 1665 DMX WDM interfaces may also be directly connected to the optical multiplex section without using the ITU defined optical channel encapsulation.
Applications
WDMX is designed for application by service providers in metro access, metro core, and extended metro deployments, as well as high capacity enterprise and campus networks.
Triple play applications
Alcatel-Lucent 1665 DMX R7.1.1 provides a great solution to the low cost Triple Play
(voice, video and data) distribution application focusing on data rates below OC48.
Service providers are dealing with the problem of enhancing video distribution and
Ethernet broadcast distribution and making it affordable. WDMX is perfectly matched to meet a major portion of that need.
Some customers have a requirement for full C-band tunable lasers and very long reach without regeneration for their video backbone networks. Although WDMX is not intended as a full range multi-haul system, it can lead to dramatic savings for the service provider. WDMX is expected to be the first system to focus the latest full set of optimized technologies for metro deployments.
Video applications typically have a two tiered network. One tier consists of national video broadcast feeds through a national core network into local Video Broadcast (VBC) and
Video-On-Demand (VoD) servers at the regional and local Video Hub Offices (VHO).
The second tier connects the VHOs with Video Service Offices (VSO). The VSO distributes the multicast VBC paths and manages the unicast connections for VoD paths.An Ethernet Aggregation Router collects and distributes traffic to and from
DSLAMs and routers in the access network.

The typical VSO will house 2 Edge Aggregation Routers (EARS). Each of the EARs will interface to:
• 2 GbE circuits (uni-directional protected east/west) for Multicast Video Channels
• 1 GbE for Internet Data (dropped and added east/west)
• 2 to 3 GbE for Video On Demand (VOD).
This is a total of 6 to 9 GbE. So, most VSOs will require less than 8 wavelengths.
However, the VHOs and Optical hubs will require more than 8 wavelengths.
MSPP exhaust applications
There are cases where there is a large jump in high bandwidth service demands along the path of an existing MSPP ring. If such services are projected to exceed the ring capacity
(capacity exhaust), WDMX can be used. Alcatel-Lucent 1665 DMX R7.1.1 allows an existing partially filled Alcatel-Lucent 1665 DMX shelf to add 10G wavelengths for client interfaces with data rates of OC-48 or below. The wavelengths added are passed transparently, which is critical to applications that would lose proprietary functionality if the client signals attempted to use standard section and line termination of SONET for transport.
Large data center/SAN high availability applications
The substantial disasters of the last ten years have caused both industry and the government to require geographical redundancy of mission critical data in real-time or near real-time to assure high availability. This requires substantial high capacity transport of Ethernet and Fibre Channel data for Fortune 1000 Enterprises.

Path switched rings
Overview
This section describes the unidirectional path switched ring configuration available with
Alcatel-Lucent 1665 DMX.
Purpose of path switched rings
The need to prevent service outage caused by network failure has created path switched ring applications. The path switched rings configuration provided by Alcatel-Lucent 1665
DMX is a self-healing network that automatically protects against service outages caused by cable cuts and equipment failures, which in turn protects customer traffic and increases revenue opportunity.
Alcatel-Lucent 1665 DMX path switched rings operate in an easily-managed, integrated, single-ended fashion. Restoration is fast and reliable. Complex network-level coordination is not necessary to restore traffic. Furthermore, bandwidth administration and network reconfigurations (for example, adding or deleting nodes) are simple because path switching does not require special time slot assignment rules.
Typical path switched ring application
A network that requires the majority of its traffic to be dropped at a single node is an ideal application for path switched rings. A typical access network, where most traffic is between the customer locations and a point-of-presence (POP) or end office, fits this mold. Such an application calls for reliable delivery between customers and POPs. In cases where a mixture of wideband and broadband services is required, an Alcatel-Lucent
1665 DMX path switched ring is ideal.
OC-3/12/48/192 path switched rings
The OC-3/12/48/192 path switched ring allows several remote sites to share the two-fiber ring facility back to the CO. Alcatel-Lucent 1665 DMX interfaces to the ring through the
Main slots at the OC-3/12/48/192 rate and uses its programmable VT1.5/STS-1/STS-
3c/STS-12c/STS-48c/STS-192c cross-connect capability. Path switching can be done on
VT1.5, STS-1, STS-3c, STS-12c, STS-48c, or STS-192c paths, or a mixture of these, and all can be added/dropped from the Alcatel-Lucent 1665 DMX path switched ring at any node. Using the ring's path protection scheme, time slots are reserved all the way around the ring. Cross-connections offer full flexibility in assigning signals between low-speed ports and the high-speed interface at each node. Alcatel-Lucent 1665 DMX can easily adapt to unpredictable growth at a ring node.

OC-3/12/48/192 UPSRs are supported on the low-speed (tributary) interfaces with the same characteristics as the high speed UPSRs described above. Alcatel-Lucent 1665
DMX supports path switching on STS-1, STS-3c, STS-12c, STS-48c, STS-192c and
VT1.5 paths only. On a per STS-n basis, Alcatel-Lucent 1665 DMX supports both revertive and non-revertive switching.
Ring topology
The ring topology routes traffic between a CO site and a set of remote sites, or between multiple COs, while providing complete protection. In addition, only two OLIUs are needed per Alcatel-Lucent 1665 DMX, which provides a cost savings. Traffic can also be routed between remote nodes. The ring can start with as few as two nodes and grow to support many nodes through in-service node additions.
For protection against a CO failure, it may be desirable to include a second CO node in the ring. Alcatel-Lucent 1665 DMX's support for dual homing architectures allows all services to be routed to the alternate CO while the first CO is out of service.
Operation
The Alcatel-Lucent 1665 DMX OC-3/12/48/192 path switched ring operates as shown in
Figure 3-23, “Path switched rings” (p. 3-41) . Traffic entering a path switched ring node is
sent onto both rotations of the ring. At the receiving node, the signal having the highest integrity (based on SONET path information) is selected and dropped as outgoing traffic.
At intermediate nodes, the traffic is "passed-through" without changing the SONET path information. The Alcatel-Lucent 1665 DMX VT1.5/STS-1/STS-3c/STS-12c/STS-
48c/STS-192c cross-connect capabilities make the provisioning of add/drop and pass-through traffic quick and easy.

The self-healing nature of the path switched ring is shown in
Figure 3-23, “Path switched rings” (p. 3-41)
(b). In this case, the fiber failure between nodes C and D causes node C to switch from the counterclockwise ring to the clockwise ring, thus maintaining service between all nodes on the ring.

Configuration advantage
Path switched rings are the industry standard for self-healing networks, providing reliable transport for access networks while accommodating almost any type of application.
2-Fiber BLSRs
Overview
A 2-fiber bidirectional line-switched ring (BLSR) is a self-healing ring configuration in which bidirectional traffic travels over the same set of nodes in each direction.
Bidirectional switching makes use of redundant (protection) bandwidth on the bidirectional lines that interconnect the nodes in the ring to provide protection for traffic carried on the working bandwidth. Because the traffic is bidirectional, a single circuit does not necessarily consume bandwidth on every span in the ring. This leaves the spans between other nodes available for additional traffic. Therefore, with distributed switching patterns, a BLSR can carry more traffic than the same facilities could carry if configured for a unidirectional path-switched ring.

2-Fiber BLSRs
....................................................................................................................................................................................................................................
Alcatel-Lucent 1665 DMX supports 15 simultaneous BLSR protection groups in a single shelf. The 15 protection groups can be provisioned on any available OC-48 and OC-192 port pairs within the high-speed and low-speed groups.
For example, you can have an application with two high-speed OC-192 2-fiber BLSR and
13 low-speed OC-48 BLSRs. The low-speed OC-48 BLSRs are hosted by OC-48 circuit packs housed in the Function slots and can add and drop traffic with the high-speed
OC-192 circuit packs housed in the Main slots. The low-speed OC-48 BLSRs can also add and drop traffic with interfaces in other tributary (low-speed) slots (includes both
Function Units and Growth slots).
Traffic capacity
The following figure shows working and protection traffic capacities in an OC-192
2-fiber BLSR. The OC-48 2-fiber BLSR operates in the same way, but has 48 STS-1 time slots in each direction, 24 for working traffic and 24 for protection.

Self-healing rings
Alcatel-Lucent 1665 DMX 2-fiber BLSRs are self-healing in that transport is automatically restored after node or fiber failures. Each OC-192 line carries 96 STS-1 equivalent time slots of working capacity plus 96 STS-1 equivalent time slots of protection capacity. Each OC-48 line carries 24 STS-1 equivalent time slots of working capacity plus 24 STS-1 equivalent time slots of protection capacity. In the event of a fiber or node failure, service is restored by switching traffic from the working capacity of the

Protection switching
When a line failure triggers a protection switch, the nodes adjacent to the failure switch traffic on to protection capacity. Traffic heading toward the failure is looped back on to the protection capacity traveling away from the failure to reach its destination by traveling the opposite way around the ring (see the figure below). Service is reestablished on the protection capacity in ≤50 milliseconds after detection of the failure (for catastrophic failures in rings without existing protection switches or extra traffic).

Protection traffic flow
In the figure above, traffic going from Node A to Node C that normally passes through
Node E and Node D on "working 2" capacity is switched at Node E on to the "protection
2" capacity of the line leaving Node E in the direction of Node A. The traffic passes through Nodes A, B, and C on the protection bandwidth to Node D where it is looped back to Node C. Similarly, traffic going from Node C to Node A that normally passes through Node D and Node E on "working 1" capacity is switched at Node D on to the
"protection 1" capacity of the line leaving Node D in the direction of Node C. The traffic passes through Nodes C, B, and A on the protection bandwidth to Node E where it is looped back to Node A. Only the nodes adjacent to the failure perform loopback protection switches. The same approach is used for a node failure. For example, if Node
D fails, Nodes C and E perform loopback protection switches to provide an alternate route for ring traffic. However, traffic that is added and dropped at the failed node, Node
D, cannot be protected by ring switching and is therefore squelched at the switching nodes.
Extra traffic
Alcatel-Lucent 1665 DMX supports extra traffic
• OC-48 BLSR on non-VLF mains
• OC-192 BLSRs (Main and FN) in systems with VLF mains

(OC-192 VLF mains are required in all contiguous nodes participating in the extra traffic part of the network.)
The extra traffic capability allows the protection channels to carry additional low-priority traffic during fault-free conditions. The extra traffic is established by provisioning cross-connections to the high-speed (main) BLSR protection channels. Provisioning cross-connections on the protection channels is only supported on high-speed BLSRs.
Pass through cross-connections are provisioned on the protection channels at intermediate nodes. (Protection channels that are not carrying Extra Traffic are terminated at the intermediate nodes.)
If a BLSR protection switch occurs, traffic is switched from the working channels to the protection channels and extra traffic is preempted.
If extra traffic circuits are preempted, AIS-P is used to squelch the circuits. When the
BLSR protection switch clears, the extra traffic is restored.
Nonpreemptive unprotected traffic
Non-preemptible unprotected traffic is traffic carried on (working and/or protection)
BLSR channels for which protection switching has been provisioned as disabled. As the name implies, NUT is unprotected and not preempted in the event of a protection switch.
BLSR protocols allow the available bandwidth of a BLSR to be partitioned into three types of channels:
• working channel to carry working traffic.
• protection channel which may be used to carry extra traffic.
• NUT channel to carry non-preemptible unprotected traffic.
Working traffic is protected against failure events via the BLSR APS protocol, while extra traffic is unprotected traffic carried on the protection channels. Any failure event that may require the protection channels for protection purposes shall preempt the extra traffic.
NUT carried on non-preemptible unprotected channels affords a higher level of survivability as compared to extra traffic, which is preempted during a protection switch, but a lower level of survivability as compared to working traffic, which is carried on its corresponding protection channel during a protection switch. Note that non-preemptible unprotected traffic is not considered extra traffic.
Important! Alcatel-Lucent 1665 DMX supports NUT on 2-fiber OC-48 and OC-192
BLSRs.

Packet rings
Overview
Packet Ring configurations provide business-to-business networking of routers and data switches using Ethernet transport over a reliable, low-cost multiservice network.
Alcatel-Lucent 1665 DMX provides the unique capability for a packet ring to span multiple ring topologies. As shown in the figure below packet rings hosted by
Alcatel-Lucent 1665 DMX can span multiple OC-192, OC-48, OC-12, OC-3 ring configurations (UPSRs or BLSRs). Additionally, packet rings hosted by Alcatel-Lucent
1665 DMX can reach into areas serviced by dual and single-homed ring extensions (see the figure below).
Ethernet over SONET
A Packet Ring is a set of packet switches connected in a ring topology that use the inherent redundancy of the ring configuration to provide durability and fast restoration in the event of failures.
Packet rings can be used with or without SONET layer protection. At the packet layer, the rapid spanning tree protocol (as defined in IEEE 802.1) is used to provide protection.

Alcatel-Lucent 1665 DMX uses standard Generic Framing Procedure (GFP) encapsulation (ITU G.7041) for Ethernet over SONET mapping. Packet rings provide efficient aggregation and transport for Ethernet traffic. Alcatel-Lucent 1665 DMX's virtual concatenation capability (ITU G.707) provides flexible bandwidth granularity in the wide area network (WAN), which can grow with your service demand.
Packet rings over a BLSR
Alcatel-Lucent 1665 DMX allows the manual provisioning of nonpreemptive unprotected traffic (NUT) for multi-point Ethernet cross-connections that originate on low-speed
(tributary) interfaces and share bandwidth on the high-speed (Network side) BLSR ring.
When using multi-point cross-connections through a BLSR, packets do not receive standard BLSR protection due to the necessary functioning of NUT. Yet, protection on all data packets is provided for with rapid spanning tree protocol (IEEE 803.1w).
Packet ring capacity
Alcatel-Lucent 1665 DMX supports 16 packet rings on each 100/1000 Mbps GbE circuit pack (LNW170).
Specific applications supported
Alcatel-Lucent 1665 DMX supports the following enterprise LAN (local area network) interconnect and transport applications:
• Ethernet Private Line
• Ethernet Rate Control Services
• Virtual LAN Services
• Transparent LAN Services
• Best Effort Service
• Ethernet/TDM Access to Frame Relay or ATM Network
• Ethernet/TDM Access to IP Network
• DSLAM Access
Each of these packet ring applications are detailed in the "Service Applications" section of this chapter.

WDMX shelf models
Overview
WDMX can be implemented by using spare slots in existing Alcatel-Lucent 1665 DMX
SONET shelves that already make use of the main slots, and a subset of the function unit and growth slots. For these applications, WDMX is a WDM overlay on top of the existing
SONET applications.
Multi-service transport over OTU-2
With the LNW705 muxponder pack, WDMX can be used without requiring SONET application packs in the shelf. Main packs are required for system timing. The LNW705
XM10G/8 Muxponder circuit pack is a highly integrated pack that multiplexes up to 8 ports of the most common high bandwidth client interfaces onto a single 10G wavelength.
The 8 client ports can be a mix of the following signals: 1GE, FC100, FICON, FC200,
FICON_EXP, 1000BASE-ZX, or OC3/12/48. One GE is mapped using VCAT and
GFP-F. All FC signals and FICON signals are mapped using VCAT and GFP-T. The client signals are mapped into a single STS-192 and then encoded into an OTN OTU-2 signal (including forward error correction) and is transmitted out on a DWDM XFP. The circuit pack is bi-directional and simultaneously handles the inverse function in the receive direction.

In the figure, multiple client signals are coming into the LNW705 on the Alcatel-Lucent
1665 DMXtend. The LNW705 multiplexes up to 8 client ports onto the single OTU-2 for transport over the fiber. The LNW705 in the Alcatel-Lucent 1665 DMX demuliplexes the signals and sends them onto another NE.
One-line unamplified 8 channel end terminal node
This model consists of an Alcatel-Lucent 1665 DMX shelf, shelf controller, 1 or 2 main packs for shelf timing, an 8 channel OMD pack (LNW785), and the following, optionally directly connected to the OMD:
• Existing Alcatel-Lucent 1665 DMX packs and functions (with the interconnect to the
LNW785 OMD pack)
• Alien wavelengths from other equipment
The OMD pack (LNW785) may be equipped in any unequipped function or growth slot.
OSMINE supported models for Alcatel-Lucent 1665 DMX allow function groups A, B,
C, and D. Growth slots on the Alcatel-Lucent 1665 DMX do not have an OSMINE model because the pass-through fibers between two growth slots on the Alcatel-Lucent 1665
DMX shelf would have to pass around the main-1 slot and the controller slot.
A one-line 8 channel end terminal can have 1 or 2 main packs, 1 LNW2 controller, 1
WDM line, 8 optical channels, and 64 client ports in a single shelf.

WDMX optical multiplexing network models
Overview
A WDM line (OTS) is a bidirectional multicolored composite optical line that connect
WDM systems into networks. If only one WDM line is used, the system is referred to as an end terminal and can be used in point to point networks or at the end of chain of ring nodes. Two lines are required for optical add/drop multiplexers (OADMs) used as rings, nodes, and in linear chains: one line faces West (slot 1 of an OMD [LNW785] pack pair, e.g., d1-ots), and the other line faces East (slot 2 of an OMD [LNW785] pack pair, e.g., d2-ots).
The following network examples illustrate various arrangements of end-terminals and add/drop ring nodes that can be used for WDMX. In the following examples, a single line represents two-fiber connections between NEs.
Point-to-point/end-terminal-to-end-terminal

Double-terminated ring
The double terminated ring is also expected to be very a common topology. It is composed of two EAR rings, joined at the end-terminals. The End terminals typically are the hubbing locations that sync and source the traffic. The Ring nodes typically allow relatively small counts of wavelengths to enter the network and send it in diversely routed directions toward independent end-terminals. This allows for the protection of services.

This arrangement provides greater flexibility. However, care must be taken to assure optical noise loops (lasing) are not created. This is accomplished by creating high attenuation on pass-throughs for all optical channels that are not equipped.

WDMX channel wavelengths
The WDMX channel wavelengths are based on the industry standard ITU-T grid at 100
GHz spacing in the Cband. The lowest frequency is 195200 GHz and the highest is
195900 GHz. The channels are generally described using only the middle four digits. For example, ITU channel 55 is at frequency 195500 GHz. Some device labeling only uses middle 2 digits. For example, 195500 GHz could also be represented on device labeling

as frequency “55”. These 8 channels overlap with the 32 channel wavelength plan of the
Lucent Wavelength Extension Solutions (WES) product, and 6 of the 32 channel wavelength plan of the EON system. (EON uses ITU-T channel 52 - 57 in common with
WDMX.)
The optical components of WDMX are optimized for transport of XFP based 10G transmitter for metro access and metro core applications. This optimization allows for lower cost of WDMX and allows for better interoperability with the alien wavelengths expected in the metro access and metro core.
DWDM optics
Overview
Alcatel-Lucent 1665 DMX supports low-cost DWDM optics. These optics include 16 different OLIUs (2 wavelengths per OLIU) for OC-48 transmission, the OMD5/8
8-channel mux/demux (LNW785), and a choice of 5 different Passive Optics Units
(POUs) where the various wavelengths are combined for transmission over one fiber. The
DWDM wavelengths or channels are chosen at 100 GHz increments per the ITU grid.
DWDM PTM-based circuit packs
Alcatel-Lucent 1665 DMX PTM-based OC-48 main and tributary packs support OC-48
DWDM PTMs. In conjunction with the POUs , these packs increase fiber capacity. The
PTM-based OC-48 main and tributary packs also support OC-48 CWDM PTMs. The
PTM-based OC-192 main and tributary packs support OC-192 DWDM PTMs. In conjunction with a mux/demux system, these packs canincrease the fiber capacity.
OC-48 DWDM/CWDM PTMs
The following circuit packs support OC-48 DWDM/CWDM PTMs
• LNW55
• LNW62
• LNW82
• LNW202
• LNW402
• LNW504
For a list of the DWDM OC-48 PTMs, see

Passive optics units
As the variety of applications listed above suggests, there are various versions of the
POU, each designed to maximize functionality in a variety of deployment scenarios. The list below details the various forms of POUs:
• 16 Channel MUX or DMUX (odd numbered channels): This POU supports unidirectional and bidirectional transmission systems.
• 16 Channel MUX or DMUX with Interleaver (even numbered channels): This POU supports unidirectional and bidirectional transmission systems, and includes an interleaver to support 16 additional channels.
• Dual 1-Channel Optical Add Drop: This POU supports unidirectional transmission systems and can add/drop one channel from a DWDM line carrying up to 32 different channels.
• Dual 2-Channel Optical Add Drop: This POU supports unidirectional transmission systems and can add/drop two channels from a DWDM line carrying up to 32 different channels.
• Dual 4-Channel Optical Add Drop: This POU supports unidirectional transmission systems and can add/drop four channels from a DWDM line carrying up to 32 different channels.
• Dual 1310 + 4x1550 MUX/DMUX: This POU provides one I/O port for 1310 nm signals and four I/O ports for 1550 nm signals. This POU supports unidirectional transmission systems and can MUX or DMUX a 1310 channel and four 1550 bands to/from a DWDM line.
Important! The last four bulleted items in the list above describe the various OADMs and MUX/DMUX as "Dual". "Dual" is in reference to the fact that each of these specific POUs are comprised of two complete sets of OADMs or MUX/DMUX units.
Thus, the dual 1-channel OADM POU contains 2 OADMs interfaces, enabling it to support 1 add/drop in each direction.

Protection
The passive optic port units support the same protection modes as the standard port units.
For example, both sets of passive port units support BLSR, UPSR, and 0x1 protection.
The DWDM passive OLIUs also support 1+1 protection.
MUX/DMUX example
The figure below shows 16 lines to and from Alcatel-Lucent 1665 DMX systems. The
OC-48 traffic from the 8 incoming (receive) and 8 outgoing (transmit) lines is transmitted over one fiber using DWDM on the Alcatel-Lucent passive optics shelf to a remote
Alcatel-Lucent passive optics shelf. The traffic is similarly transmitted and received by that system. Alternatively, the equipment can be set up to handle 16 or 32 transmit lines on one end of the passive optics unit and 16 or 32 receive lines on the other end.

Increased span length: external DWDM optical amplifiers
(OAs)
Overview
For OC-192 spans of up to 140km, Alcatel-Lucent offers DWDM optical amplifiers. The
DWDM optical amplifier is a stand-alone shelf and can be used with both regular and
DWDM OC-48 and OC-192 optics.
Concept
Optical amplifiers consist of one booster and one pre-amplifier part. The booster part is connected via a Dispersion Compensation Module (DCM) to the transmit interface of the respective OC-192 or OC-48 port unit. The pre-amplifier is connected by means of a
DCM to the receive interface of the associated port unit.
Applications
The DWDM optical amplifier has two main applications:
• Single span application
• Multiple span application
A simple example for a single span application is shown in the following figure.

Dual node ring interworking
Overview
Dual node ring interworking (DRI) is a configuration that provides path-level protection for selected STS-N circuits that are being carried through two UPSRs. Protection for the route between the two rings is provided by interconnecting the rings at two places (see
Figure 3-33, “Dual ring interworking protection” (p. 3-59) .
Each circuit that is provisioned with DRI protection is dual-homed, meaning it is duplicated and subsequently passed-through at two different nodes on a ring. The two interconnecting nodes in each ring do not need to be adjacent.
DRI protection
The self-healing mechanisms of the two UPSRs remain independent and together protect against simultaneous single failures on both rings (not affecting the interconnections).
The DRI configuration additionally protects against failures in either of the interconnections between the rings, whether the failure is in a facility or an interconnection node.
Ring interworking
All Alcatel-Lucent 1665 DMX tributary SONET interfaces (OC-3, OC-12, and OC-48) support DRI. The Alcatel-Lucent 1665 DMX high-speed ring can be an OC-12/48/192
UPSR. An Alcatel-Lucent 1665 DMX ring supports DRI with UPSRs, including rings using the following products:
• Alcatel-Lucent 1665 DMX
• WaveStar

TDM 2.5G/10G (2-Fiber)
• WaveStar
®
BandWidth Manager
• DDM-2000 OC-3
• DDM-2000 OC-12
• FT-2000 ADR
Additionally, there can be intermediate network elements in the interconnection routes between the two rings.
UPSR-to-UPSR interworking
In the UPSR to UPSR interworking both UPSR DRI nodes select the better of two paths travelling in the drop direction and pass traffic to one rotation of the ring in the add direction.

UPSR drop and continue
Alcatel-Lucent 1665 DMX supports the drop and continue method of DRI, in which both
UPSR DRI nodes select the better of two paths travelling in the drop direction and pass traffic to one rotation of the ring in the add direction. Each node drops the circuit in the direction of the other ring and a pass-through circuit to the other DRI node is made. The best of the 2 resulting signals is dropped at the terminating node of the new ring.
UPSR to UPSR protection switching example
The figure below illustrates a failure of the interconnection to a DRI node at the point labeled "X" in the figure. A failure in the route from Node A to Node Z results in a path switch at the surrounding nodes adjacent to the failure. The DRI nodes themselves will only perform the protection switch if they are the nodes adjacent to the failure. As you can see, while all nodes and lines remain fully functional, DRI functions as described in the section above. Both DRI nodes in the top ring select the best of the 2 signals received from that ring, and transmit them to the DRI nodes in the lower ring. The best of the signals received at the terminating node is dropped.
A path protection switch in an Alcatel-Lucent 1665 DMX occurs in <50 milliseconds (not counting the detection time) at the nodes adjacent to any failure.

Single- and dual-homing
Overview
End users are demanding service with high availability. Service providers are responding with tariffs that rely on self-healing networks to offer high availability service. Some of these tariffs even call for penalties for the service provider when service is interrupted or has a high error rate. The Alcatel-Lucent SONET product family offers many options for meeting Alcatel-Lucent 1665 DMX service needs. One of these, OC-3/12/48 ring transport on Alcatel-Lucent 1665 DMX ring networks, can be implemented in single- and dual-homing configurations.
For lower-density TDM applications, Alcatel-Lucent 1665 DMX can provide an
OC-3/12/48 optical ring termination for a DDM-2000 OC-3 Multiplexer, DDM-2000
OC-12 Multiplexer, DDM-2000 FiberReach, or any other compliant network element.
This feeder ring is useful for evolving lower-density access transport applications into high-rate access networks.
Description
The figure below shows a dual-homed OC-3 extension from two remote nodes on an
Alcatel-Lucent 1665 DMX access ring. OC-3 extensions from Alcatel-Lucent 1665 DMX rings are available when the Alcatel-Lucent 1665 DMX Function Unit groups are equipped with OC-3 OLIU circuit packs. OC-12/48 extensions from Alcatel-Lucent 1665
DMX rings are also available. The host nodes must be Alcatel-Lucent 1665 DMX NEs.

The figure below provides an example of both single and dual-homing. Path protection switching is employed for dual-homed and single-homed applications in the same manner. That is, 50 millisecond path switching is supplied by the remote DDM-2000
OC-3/OC-12/FiberReach nodes and the Alcatel-Lucent 1665 DMX systems. The
Alcatel-Lucent 1665 DMX host node dual homing configuration differs from that used for single-homing because each host node transports only one leg of the
OC-3/OC-12/OC-48 extension. At each host node, a connection is made from the single
OC-3/OC-12/OC-48 extension to just one rotation of the Alcatel-Lucent 1665 DMX host ring. Dual- and single-homed extensions can also be mixed at a host node, allowing the access network to be tailored efficiently to different groups of customers. Host nodes could also be Alcatel-Lucent 1665 DMXtend.

Hairpinning
Overview
Alcatel-Lucent 1665 DMX supports both inter-function group, intra-function group, intra-port as well as pass-through hairpinning cross-connections. These capabilities allow you to route traffic in and out of Alcatel-Lucent 1665 DMX without consuming bandwidth on the high-speed (OC-3/12/48/192) interfaces, and to host multiple rings on the low-speed interfaces of the Alcatel-Lucent 1665 DMX shelf (OC-48, OC-12, OC-3).
Inter-function group hairpin
In a "hairpinning" topology, low-speed tributary traffic is routed into the system and back out of the system without ever being placed on the high-speed (OC-12/48/192) UPSR interfaces (this description assumes that the MAINs are provisioned for UPSR protection, but intra-function group hairpins are supported on all MAIN application/protection schemes). The cross-connection capability of connecting any input on a circuit pack in a function or growth slot to any output on a circuit pack in a different function or growth slot of the same shelf allows you to use a combination of add/drop and hairpinning of compatible payloads through a variety of interfaces. You can bring traffic in from one remote site and cross-connect it at the VT, STS-1, STS-3c, STS-12c, STS-48c, or
STS-192c level back out to other remote sites without consuming any capacity on the high-speed UPSRs.

Low-speed ring closure
Alcatel-Lucent 1665 DMX can host multiple rings on the low-speed interfaces of the
Alcatel-Lucent 1665 DMX shelf. This is accomplished by either protected drops from a
UPSR or UPSR pass-throughs. Alcatel-Lucent 1665 DMX can close a low-speed ring by supporting a cross-connection between a receive port on one circuit pack and a corresponding transmit port on another companion circuit pack in the same function or growth group (cross-connections can also be made to ports in any other slot on the shelf).
All protection switching advantages/capabilities of UPSR configurations still apply in the low-speed ring closure application shown below.

Intra-function group hairpin
Alcatel-Lucent 1665 DMX supports intra-function group, hairpin cross-connections that are cross-connections between different tributaries on different ports within the same function group. Again, the application above could be enabled by either intra-function group hairpins or UPSR pass-throughs. Intra-function group hairpins are available in all protection schemes, not just in UPSR applications.
Intra-port hairpin
Alcatel-Lucent 1665 DMX supports the provisioning of intra-port cross-connection on
UPSR interfaces. Intra-port characterizes cross-connections between channels/time slots/tributaries hosted on the same port.

Linear optical extensions
Overview
An additional topological flexibility offered by the Alcatel-Lucent 1665 DMX is 1+1 protected linear OC-3, OC-12, OC-48, OC-192 optical extensions from the
Alcatel-Lucent 1665 DMX ring. Using this capability, Alcatel-Lucent 1665 DMX can support many of the new network configurations desired in evolving access networks.
Description
An access provider can use linear optical extensions from an OC-12/48/192 ring to provide OC-3, OC-12, and OC-48 signals directly to end users. This gives the end users the bandwidth they need for large bandwidth applications, such as video, data, and ATM.
Linear optical extensions can also be used to interconnect SONET subnetworks.
Examples include interconnection of two access networks and interconnection between access and interoffice rings. Optical extensions can be used to interconnect
Alcatel-Lucent 1665 DMX ring networks to an OC-3, OC-12, or OC-48 terminal, an
OC-3, OC-12, OC-48, or OC-192 add/drop network, or another OC-3, OC-12, OC-48, or
OC-192 ring. Intra-port hairpins are supported on 1+1 protected interfaces.

Overview
The Alcatel-Lucent 1665 DMX hubbing topology provides metropolitan-area and regional-area network infrastructures based on a single NE.
Description
An Alcatel-Lucent 1665 DMX high-speed UPSR ring can serve as a core feeder ring, transporting voice and data from metropolitan networks to the optical core network and vice versa.
As shown in
Figure 3-39, “Hubbing application” (p. 3-67) , one Alcatel-Lucent 1665
DMX node is configured as a core feeder node, providing a conduit from the optical core to the OC-48/192 access network. On the ring, another Alcatel-Lucent 1665 DMX is configured as the hub node, where several Alcatel-Lucent 1665 DMX and DDM UPSR rings are terminated. The hub node grooms the traffic and cross-connects it to the appropriate ring.
One Alcatel-Lucent 1665 DMX can be configured as a hub node for up to 80 OC-3 rings,
40 OC-12 rings, 20 OC-48 rings, or, as pictured below, a mixture of high- and low-speed rings.

Control plane E-NNI interface
Overview
The basic functions of a control plane for an Automatically Switched Optical Network
(ASON) are signaling and routing. Signaling is used to establish, maintain, and tear down end-to-end connections. Routing is used to select the most appropriate path between and within network domains. The data communications network for transferring this control plane information (signaling and routing messages) is called Signaling Communications
Network (SCN).
In this release, the Alcatel-Lucent 1665 DMX supports the control plane E-NNI logical interface over inter-domain links for single node access domain configuration. The signaling protocol is RSVP-TE and routing protocol is OSPF-TE, based on OIF specifications.
E-NNI Functions
An example of a control plane network with Alcatel-Lucent 1665 DMX E-NNI connecting to an I-NNI capable core is shown below. In this example Alcatel-Lucent
1665 DMX NEs serve as edge nodes and Alcatel-Lucent 1675 LambdaUnite MSS NEs, or other vendors’ NEs, serve as core nodes. The core domain nodes support I-NNI within the domain and E-NNI between the domains.

The transport topology is SONET linear for the E-NNI, and mesh for the I-NNI. SONET linear topology supports unprotected and line 1+1 protection schemes. The mesh topology supports control plane-based protection schemes including 1+1 path (network) protection, dynamic reroute, and unprotected.
The primary function offered by such a network is the ability to create and delete end-to-end DS3, OCn, and Ethernet Private Line services between an ingress and an egress client-facing edge port. The connection setup and release are invoked by TL1 commands sent to the source edge node from OS, and carried out by the control plane
(E-NNI and I-NNI). The connection can be either unidirectional or bi-directional. The signal rates for connections are restricted to STS-1, STS-3c, STS-12c, STS-48c, and
STS-192c.
In Alcatel-Lucent 1665 DMX, an optical port is configured as TRADITIONAL, EDGE or
ENNI, with TRADITIONAL as the default. The TRADITIONAL ports are outside of the control plane topology. The setup of cross connects associated with TRADITIONAL ports is managed as it was previous to the introduction of ENNI on Alcatel-Lucent 1665
DMX. The setup of cross connects associated with ENNI ports is controlled by the E-NNI control plane. The EDGE ports function as add/drop ports of the end-to-end control plane connections. A sub-network point (time slot) in an EDGE port can be used for either end-to-end control plane connections or traditional connections.

Signaling Communications Network (SCN)
Control plane signaling (particularly E-NNI in this feature) and routing messages must be transferred between network entities by a dedicated IP based data communications network, which is referred to as Signaling Communications Network (SCN). It should be noted that the SCN topology is not necessarily the same as that of the transport network.
Alcatel-Lucent 1665 DMX SCN supports both in-fiber (Line DCC) and out-of-fiber
(LAN, specifically LAN-3) communication interfaces as signaling control channels. The inter-domain routing for SCN is based on manual routes.
Multi-shelf DCS utilizing a single TID
Purpose
The multi-shelf DCS feature provides a method of adding additional DS1 and DS3
(TMUX) I/O capacity to a system, through the addition of DS1 and/or DS3 add/drop sub-shelves, while maintaining the ability to externally manage the entire multi-shelf system via a single TID. Most features and provisioning currently supported on a
Alcatel-Lucent 1665 DMX are supported on the main shelf in the multi-shelf DCS configuration.
Multi-shelf requirements
A main shelf must be equipped with VLF mains to support sub-shelves. The pack types supported in the add/drop sub-shelves are restricted. Each sub-shelf type (DS1 or DS3) supports a fixed set of cross-connections between the DS1/DS3 ports and the main ports in the subshelf. The user can provision cross-connections independently to each DS1/DS3

port in the subshelf. The transmission link between the main shelf and each sub-shelf is a unidirectional, non-revertive 1+1 protected OC-n link (OC-12 for a DS1 sub-shelf and
OC-192 for a DS3 sub-shelf).
Maximum number of sub-shelves
Alcatel-Lucent 1665 DMX supports either
• 12 DS1 sub-shelves and 1 DS3 sub-shelf
• 2 DS3 sub-shelves
When the total number of sub-shelves exceeds the limit, the sub-shelf commands are not available from the main shelf.
The operations connection between the main shelf and the sub-shelves is through the
LAN3 (J18 DLAN) port on the backplane.
DS1 sub-shelf
A fully-populated DS1 sub-shelf supports up to 4 pairs of LNW801 packs in the function group slots and one pair of OC-12 packs (LNW48, LNW50, LNW203) in the main slots.
Any other pack is alarmed as an unexpected circuit pack. The LNW801 ports are configured as DS1 ports. E1 interfaces are not supported. The OC-n ports on the main packs are configured as a unidirectional, nonrevertive 1+1 protection group.
DS1 sub-shelf cross-connects
The following 2-way cross-connectivity is fixed within a DS1 sub-shelf. These cross-connections provide non-blocking access from the main shelf to all 224 DS1s in the sub-shelf.

Mixed release rings
Switched Ethernet and/or LCAS and BLSR
Alcatel-Lucent 1665 DMX supports the following mixed releases in the same ring:
• R5.1.3/R5.1.6/R6.0.3 and R7.0.3
• R5.1.3/R5.1.4/R5.1.6/R6.0.1/R6.0.4 and R7.1.2
• R7.0.2/R7.0.3 and R7.1.2
• R7.1.2 and R8.0
Considerations for mixed release rings
In a mixed network, features are limited to the content of the lowest release for a given node pair.
All nodes should be upgraded to the same release prior to adding or deleting a node in a ring.
All nodes should be upgraded to the same release prior to upgrading the ring to a higher rate (OC-3/STM-1 to OC-12/STM-4) .
A Gateway Network Element (GNE) should be upgraded to the latest release.

Shelf description
Overview
Alcatel-Lucent 1665 DMX is a single-shelf multiplexer that can house DS1/E1,
DS3/EC1, TransMUX, OC-3, OC-12, OC-48, OC-192, 10/100T (optical and electrical),
1G T/SX/LX/ZX, and SAN (FICON/ESCON/FC) circuit packs.
High-capacity shelf
The High-Capacity shelf is the standard shelf design and can operate using any release of
Alcatel-Lucent 1665 DMX software. It incorporates DS1/DS3 D-SUB cable connectors on the rear of the shelf that were not available on an earlier design, and enable
Alcatel-Lucent 1665 DMX to support 224 DS1/E1s or 192 DS3/EC-1s. In order to support this amount of traffic, the Alcatel-Lucent 1665 DMX High-Capacity shelf must be equipped with high-density DS1/E1 and DS3/EC-1 circuit packs.
The High-Capacity shelf also has the following characteristics:
• Width: 17.6 inches
• Height: 19 inches (includes integral fan unit)
• Depth front to back with rear cover installed
– 16 inches with flush front cover installed
– 17 inches with extended front cover installed
– Removal of rear cover subtracts 0.8 inches from the depth of the shelf
• Weight (with circuit packs): 57 pounds
• Weight (without circuit packs): 38 pounds
Up to four Alcatel-Lucent 1665 DMX High-Capacity shelves can fit in a bay (including integral fan unit), and all shelves are individually mounted.
The Alcatel-Lucent 1665 DMX High-Capacity shelf is is equipped with 30 amp circuit breakers.
Capacity
When equipped with VLF Mains (LNW59, LNW82, and LNW504), each Function Unit and Growth slot in the Alcatel-Lucent 1665 DMX shelf has a 10 Gb/s IO capacity. The
LNW59 VLF Mains increase the capacity of the Main slots to 20 Gb/s. The LNW504
VLF Mains increase the capacity of the Main slots to 40 Gb/s.
When VLF Mains are not used, each Function Unit slot in the Alcatel-Lucent 1665 DMX shelf has a 2.5 Gb/s IO capacity. Even though the Growth slots have 5 Gb/s capacity only
2.5Gb/s is used. The Main slots have 10 Gb/s.

Interface density
Alcatel-Lucent 1665 DMX provides a VT1.5 and STS-1 cross-connect fabric.
Alcatel-Lucent 1665 DMX's main switch fabric is contained in each of the high-speed
(network-side interface) circuit packs, located in the MAIN slots. The MAIN slots house
OC-3, OC-12, OC-48, and OC-192 high-speed interfaces.
They can also house the LNW80 switch pack. The LNW59, LNW82, and LNW504 VLF
Main circuit packs support true 0x1 Function/Growth slot equipage. True 0x1 allows different types of circuit packs to be mixed within a function or growth group. In many cases, this doubles the overall capacity of the shelf. A high-speed OC-n line can also be provisioned as 0x1.
The table below details the maximum number of signals that Alcatel-Lucent 1665 DMX can transport if all Function Unit groups, and Growth Slots where applicable, are equipped with a particular circuit pack. For example, if the required VLF Main circuit pack is installed, and both slots in the four Function Unit groups and both Growth slots are equipped with the LNW64 circuit packs, then 80 1000BASE-SX/LX/ZX ports are supported. This results from 5 pairs of LNW64 packs, a total of 10 packs, each supporting
8 ports.

Notes:
1.
Alcatel-Lucent 1665 DMX does not allow installation of two packs with electrical interfaces in adjacent slots within the same Function Unit or Growth Group (other than an equipment-protected pair). only supports electrical packs in Slot 1 of a group. However, another optical (Ethernet or SONET) pack may be installed in the other slot.
Alcatel-Lucent 1665 DMX also provides virtual concatenation (VCAT) at the STS-1,
STS-3c, or VT1.5 rates, depending on the pack. VCAT increases flexibility when managing Ethernet services.

When the shelf is equipped with non-VLF Mains, Ethernet and SAN circuit packs are restricted to slot 1 of a function unit (for example, slot D1). If slot 1 of a function unit is equipped with an Ethernet or SAN circuit pack, then slot 2 must be equipped with a 177D apparatus blank or an LNW98 detectable blank circuit pack.
When the shelf is equipped with the LNW59, LNW82, or LNW504 VLF Mains, Ethernet and SAN packs can reside in Slots 1 and 2 of a function unit. See
Chapter 6, “System planning and engineering”
for restrictions.
Growth slots
Growth slots G1 and G2 can be equipped, depending on the application, with the following circuit packs:
• DS1/DS3/EC-1 TransMUX (LNW20)
• OC-3 PTM-based (LNW37, LNW45)
• OC-12 PTM-based (LNW49)

• Detectable Blank (LNW98)
• Blank (177D)
Note: The G slots can only support electrical Ethernet services through electrical
PTMs. When the LNW74 is installed in the Growth slots, only the optical ports are functional. Because the LNW74 does not support electrical PTMs, 10/100BASE-T ports cannot be utilize when the LNW74 are installed in a Growth slot.
Since the LNW87 and LNW170 packs support electrical PTMs the PTM-based
100/1000BASE-T ports are supported in the Growth slots when these backs are installed.
When the shelf is equipped with non-VLF Mains, Ethernet and SAN circuit packs are restricted to slot G1. If slot G1 is equipped with an Ethernet or SAN circuit pack, then slot G2 must be equipped with a 177D apparatus blank or an LNW98 detectable blank circuit pack.
When the shelf is equipped with VLF Mains, Ethernet and SAN packs can reside in Slots
G1 and G2. See
Chapter 6, “System planning and engineering”
for restrictions.
The LNW20 (48 DS3/EC1TransMUX) will not function in Portless mode when the shelf is equipped with certain Main interface packs. It is also restricted to Portless mode only when installed in Growth Slots. Therefore the LNW20 cannot be used in the Growth Slots when certain Main packs are used. Refer to
Table 4-3, “Main circuit packs that allow portless LNW20 operation” (p. 4-20) .

Main slots
The main slots M1 and M2 can be equipped, depending on the application, with the following circuit packs:
• OC-12 OLIU circuit pack: LNW48, LNW50, LNW203
• OC-48 OLIU circuit packs: LNW27, LNW29, LNW76, LNW202
• OC-3/12/48 multi-rate VLF OLIU: LNW82
• OC-192 OLIU circuit packs: LNW56 and LNW58, or LNW502
• OC-192 VLF OLIU: LNW59
• Main Switch Circuit Pack: LNW80
• OC-48/192 multi-rate VLF OLIU: LNW504
The Stratum 3 timing generator and central TDM switch fabrics are embedded in all of the MAIN circuit packs. If main slot M1 or M2 is not equipped with a circuit pack, the slot must be equipped with a 177E apparatus blank or an LNW97 detectable blank circuit pack. There is no switch fabric on the blank circuit packs.
Alcatel-Lucent 1665 DMX supports LNW59, LNW82, and LNW504 VLF Main circuit packs. VLF Mains are designed to drastically increase the overall switch fabric capacity of Alcatel-Lucent 1665 DMX. When Alcatel-Lucent 1665 DMX is equipped with VLF
Mains, the switch fabrics of the low-speed, tributary packs are not used. Rather, all switching functions are performed on the VLF Main Fabric.
Control slot
The control slot CTL is reserved for the non-redundant System Controller (SYSCTL) circuit pack. Current software requires the use of the LNW2 SYSCTL.

Notes:
1.
In order to support Ethernet and SAN packs in both Slot 1 and 2 of a Function or Growth Group,
Alcatel-Lucent 1665 DMX must be equipped with VLF Mains (LNW59/LNW82/LNW504). When the shelf is equipped non-VLF mains, the Ethernet circuit packs are only supported in Slot 1 of a group. However, when the LNW170 is in equipment-protected mode, it is supported in both slots of a group with VLF and non-VLF mains.
2.
Alcatel-Lucent 1665 DMX does not allow installation of two packs with electrical interfaces in adjacent slots within the same Function Unit or Growth Group (other than an equipment-protected pair). Telcordia
®
OS systems only support electrical packs in Slot 1 of a group. However, another optical (Ethernet or SONET) pack may be installed in the other slot.
3.
When populating the MAIN slots in the Alcatel-Lucent 1665 DMX shelf, it is imperative that both MAIN 1 and MAIN 2 contain circuit packs with identical VT switch fabric size. The Alcatel-Lucent 1665 DMX
OC-48 circuit packs, for example, contain fabrics ranging from 12 STS-1 to VLF capacity. It is therefore very important that you look carefully at the switch fabric sizes of your high-speed circuit packs while planning your order.
4.
These PTM-based circuit packs are OSP hardened, but they must also be equipped with OSP-hardened
PTMs to operate in OSP environments.
Circuit pack descriptions
Overview
This section briefly describes Alcatel-Lucent 1665 DMX circuit packs.
System Controller (LNW2)
The SYSCTL provides communication with other circuit packs on the Alcatel-Lucent
1665 DMX shelf. The SYSCTL supports all Alcatel-Lucent 1665 DMX operations interfaces, including IAO LAN (OSI or TCP/IP), CIT, office alarms, and miscellaneous discretes. The SYSCTL also supports DCC terminations for each optical line interface.

Product description
Circuit pack descriptions
....................................................................................................................................................................................................................................
The SYSCTL faceplate has push-button switches, alarm/status LEDs, and a 35-segment numeric LED display to facilitate local operations. Data redundancy is provided by two separate NVMs. Transmission is not affected if the SYSCTL fails.
The SYSCTL circuit pack provides a microprocessor, nonvolatile memory to store the generic program software and provisioning database, and additional memory for system operation. The SYSCTL circuit pack also has interfaces across the backplane to monitor and control every circuit pack in the shelf.
The SYSCTL supports CIT front access to the Alcatel-Lucent 1665 DMX via the IAO
LAN and a serial RS-232 port located on the back of the Alcatel-Lucent 1665 DMX shelf.
LNW2 comes equipped with two removable Non-volatile Memory (NVM) cards that can also be ordered separately. An Alcatel-Lucent 1665 DMX shelf will only function properly when it is equipped with an LNW2 card that contains two fully functioning
NVM cards. The NVM cards are removable/replaceable.
28DS1PM (LNW7)
Note: The LNW7 circuit pack is not supported when Alcatel-Lucent 1665 DMX is equipped with VLF Main (LNW59/LNW82/LNW504) circuit packs.
The LNW7 circuit pack contains 28 DS1 ports that can be cross-connected to VT1.5 time slots when the system is operating with a UPSR, 1+1, or BLSR Main interface. Hairpin cross-connections to OC-n and other electrical interfaces are also supported. The circuit pack is 1x1 protected, and non-revertive protection switching is supported. Line build-outs and DS1 signal encoding are software provisionable. The pack terminates up to
28 bidirectional DS1 electrical signals and supports the transport of DS1 signals coded in either alternate mark inversion (AMI) or bipolar 8-zero substitution (B8ZS) modes. The signals received from the DSX-1 are mapped into SONET VT1.5 signals and then routed to the high-speed OLIU circuit pack.
The LNW7 circuit pack can occupy Function Unit groups A, B, C, and D. All electric interface circuit packs are 1x1 hardware protected. So, although both slots in each group can house an LNW7 circuit pack, one slot in each group populated by LNW7 circuit packs is always used for hardware protection. Thus the Alcatel-Lucent 1665 DMX shelf supports up to 112 working ports when four Function Unit groups are equipped with the
LNW7 circuit pack.
In addition to maintenance and provisioning functions, the 28DS1PM circuit pack provides performance monitoring capabilities.

56DS1/E1 (LNW8/LNW801)
The LNW8 and LNW801 circuit packs can be used only in the High-Capacity shelf and contain 56 DS1/E1 ports that can be cross-connected to VT or STS-1 time slots in DS1 mode and STS3(c) time slots in E1 mode. The LNW8/LNW801 circuit packs have common functionality and they are directly interchangable. Beginning in Release 9.1, an
LNW8 and an LNW801 can occupy companion slots at the same time.
The 56DS1/E1 packs are 1x1 protected by default, and non-revertive protection switching is supported. The LNW8/LNW801 does not support true 0x1 operation. The LNW8 and
LNW801 can be used as a protection pair. For unprotected operation, install an
LNW8/LNW801 in one slot and leave the companion slot empty. There is no application parameter to provision. The Alcatel-Lucent 1665 DMX does not allow electrical TDM packs (and other packs that require rear access) to be paired with any other working packs in the same Function group or Growth group. For a detailed description of circuit pack equipage guidelines, see
Chapter 6, “System planning and engineering” .
Line build-outs and DS1 signal encoding are software provisionable. These packs terminate up to 56 bidirectional DS1 electrical signals and support the transport of DS1 signals coded in either alternate mark inversion (AMI) or bipolar 8-zero substitution
(B8ZS) modes. The signals received from the DSX-1 are mapped into SONET VT1.5
signals and then routed to the high-speed OLIU circuit pack. DS1 signals can be connected directly to high-speed BLSRs at the VT1 rate. DS1 Bipolar Violations indicate if the BPV threshold has been exceeded and the DS1 signal incoming from the DSX-1 is being translated to an outgoing far-end DS1 signal LOS or LOF.
The E1 ports have 120 Ohm terminations, and are HDB3-encoded. The mapping is E1
<-> VC-12 <-> TU-12 <-TUG2 <-> TUG3 <->VC-4 (treated as an STS3c). When the
LNW8/LNW801 is provisioned for E1 interfaces the output of the card will always be an
STS-3c regardless of the amount of traffic it is actually handling.
56DS1/E1 circuit packs can occupy Function Unit groups A, B, C, and D. Electric interface circuit packs are 1x1 hardware protected. So, although both slots in each function group can house LNW8/LNW801 circuit packs, one slot in each function group populated by LNW8/LNW801 circuit packs is always used for hardware protection. Thus the Alcatel-Lucent 1665 DMX shelf supports up to 224 working ports when four
Function Unit groups are equipped with the LNW8/LNW801 circuit pack.
In addition to maintenance and provisioning functions, the 56DS1/E1 circuit pack provides performance monitoring capabilities.
12DS3/EC1 (LNW16)
The 12DS3/EC1 (LNW16) circuit pack contains 12 ports and supports non-revertive protection switching. The 12DS3/EC1 circuit pack provides bidirectional transport of 12
DS3 or EC-1 signals and maps the DS3s into STS-1 signals, and supports transport of

DS3 signals coded in bipolar 3-zero substitution (B3ZS). DS3 or EC-1 service is provisionable on a per-port basis within each pack. LNW16 is environmentally hardened for outside plant (OSP) deployments.
The LNW16 does not support 0x1 operation. For unprotected operation, only install an
LNW16 in one slot and leave the companion slot empty. There is no application parameter to provision. The LNW16 may occupy Function Unit groups A, B, C, and D.
Electrical interface circuit packs are 1x1 hardware protected. So, although both slots in each function group can house an LNW16 circuit pack, one slot in each function group populated by LNW16 circuit pack is always used for hardware protection. Thus the
Alcatel-Lucent 1665 DMX shelf supports up to 48 working ports when four Function
Unit groups are equipped with the LNW16 circuit packs.
TransMUX circuit pack (LNW18)
Alcatel-Lucent 1665 DMX supports a 12-port TransMUX card that can collect various
DS1 signals from around a ring and combine them into a channelized DS3 signal. The
LNW18 circuit pack is environmentally hardened for outside plant (OSP) deployments.
The LNW18 circuit pack may occupy Function Unit groups A, B, C, and D. Electric interface circuit packs are 1x1 hardware protected. So, although both slots in each function group can house an LNW18 circuit pack, one slot in each function group populated by LNW18 circuit pack is always used for hardware protection. Thus the
Alcatel-Lucent 1665 DMX shelf supports up to 48 working ports when four Function
Unit groups are equipped with the LNW18 circuit packs.
The TransMUX circuit pack functions in the following manner:
Transmit Functions
• Receives a B3ZS-encoded DS3 signal from a DSX-3
• Recovers DS3 clock and NRZ data
• Calculates parity errors on the DS3 input
• Demultiplexes the M13 or C-bit formatted DS3 signal into 28 DS1s
• Maps the 28 DS1s into VT1.5s and then into an STS-1
• Inserts STS-1 path overhead
• Provides the STS-1 signal to the OLIU circuit packs
Receive Functions
• Interprets the STS-1 pointer values
• Terminates the STS-1 path
• De-interleaves the STS-1 signal into 28 VT1.5s and interprets VT pointer values
• Converts the VT1.5 signals to 28 DS1 signals
• Multiplexes the 28 DS1 signals to an M13 or C-bit formatted DS3 signal

• B3ZS encodes the outgoing DS3 signal
• Pre-equalizes the DS3 signal (with LBO) and transmits it to a DSX-3
48DS3/EC1 (LNW19B)
The 48DS3/EC1 (LNW19B) circuit pack contains 48 ports and supports non-revertive protection switching. The 48DS3/EC1 circuit pack provides bidirectional transport of 48
DS3 or EC-1 signals and maps the DS3s into STS-1 signals, and supports transport of
DS3 signals coded in bipolar 3-zero substitution (B3ZS). DS3 or EC-1 service is provisionable on a per-port basis within each pack. LNW19B is environmentally hardened for outside plant (OSP) deployments. The LNW19B supports DS3 terminal loopbacks.
The LNW19B does not support 0x1 operation. For unprotected operation, only install an
LNW19B in one slot and leave the companion slot empty. There is no application parameter to provision. The LNW19B may occupy Function Unit groups A, B, C, and D.
Electric interface circuit packs are 1x1 hardware protected. So, although both slots in each function group can house an LNW19B circuit pack, one slot in each function group populated by LNW19B circuit pack is always used for hardware protection. Thus the
Alcatel-Lucent 1665 DMX shelf supports up to 192 working ports when four Function
Unit groups are equipped with the LNW19B circuit packs.
48DS3/EC1/TransMUX (LNW20)
The LNW20 circuit pack provides 48 ports supporting DS3, EC1, and TMUX functionality on a port-by-port basis. Each port can be individually provisioned EC1, ported channelized DS3, ported unchannelized DS3, or portless DS3. With the LNW20, one high-density pack can be used for all DS3, EC1, and/or TransMUX applications.
LNW20 can be 1x1 protected or function in 0x1 unprotected mode. It supports hairpins to other packs in the shelf, and between ports on the same pack.
Portless DS3 mode does not utilize any of the electrical ports on the pack. When a port is provisioned for Portless DS3 operation, a channelized DS3 signal within an STS-1 tributary from a SONET interface on a different circuit pack (OC-n or EC-1) or the same circuit pack (an EC-1 on another port) is terminated and demultiplexed into constituent
DS1 signals. The DS1 signals are encapsulated into VT1.5 signals and cross-connected at the VT-level within the cross-connection fabric on the Main circuit pack to any other interface that supports DS1 signal transport, including a DS1 interface, a channelized DS3 interface, an EC-1 or OC-n interface. This requires two bidirectional backplane STS-1 signals to convert a single (bidirectional) STS-1 channel.
If the Main slots are equipped with Very Large Fabric LNW59, LNW82, or LNW504 circuit packs, portless operation is supported on all LNW20 ports when the circuit pack is installed in any Function/Growth group.

If the Main slots are equipped with large fabric (non-VLF) circuit packs, portless DS3 operation is only supported on the odd ports in the Function/Growth groups. The corresponding even port (odd port plus one) is unavailable.
Unless the Main slots are equipped with large fabric or very large fabric OLIU circuit packs, portless DS3 operation is not supported and any attempts to provision portless DS3 operation are denied.
LNW20 only functions in portless mode in G1/G2 and only large fabric and VLF Mains support portless mode. If other packs are installed in the main slots, the LNW20 cannot be used in G1/G2.

Alcatel-Lucent 1665 DMX does not allow 2 electrical TDM packs of different types (or any packs that require rear access) to occupy adjacent slots in the same Function Group.
So, although 0x1 functionality allows LNW20 to function unprotected, overall capacity is not increased. A total of 192 ports are available when all slots are equipped with LNW20 circuit packs (a maximum of 240 ports are available when the LNW20 is functioning in portless mode and the shelf is equipped with VLF Mains). This is because LNW20 must function in portless mode when installed in the Growth Slots. Though the LNW20

(MPMR), pack with integrated STS and VT fabrics. The pack supports a maximum of 12
OC-3 interfaces, 12 OC-12 interfaces or 4 OC-48 interfaces. The LNW55 is only supported in systems that are equipped with VLF Main circuit packs.
The mixing of interface rates is supported with the following restrictions:
• OC-48 interfaces are only supported on ports 1, 4, 7 and 10.
• When one of these ports is operating at the OC-48 rate, then the next two adjacent ports cannot be used.
For example, if port 1 is operating as an OC-48 port, then ports 2 and 3 are unavailable for use.
OC-3, OC-12 or OC-48 operation can be selected independently on a per port basis, up to the maximum number of ports supported for each interface type. The supported protection applications (1+1, 1+1_OPTM, UPSR, 0x1 and BLSR [OC-48]) can also be provisioned on a per port basis. The system supports SONET ports on the TDM optical packs.
However, the ports are capable of interworking with older SDH interfaces by provisioning the outgoing SS bits to 10. If there is a mismatch in the provisioned
(transmitted) SS bits and the received SS bits, an inc. STSN SS Bit Mismatch is declared.
The pack supports true 0x1 operation and can be installed in the function and growth slots of Alcatel-Lucent 1665 DMX and Alcatel-Lucent 1665 DMXtend shelves.

FC-DATA optical SAN interface (LNW73 and LNW73C)
The LNW73 and LNW73C circuit packs are 4-port Storage Area Networking (SAN) interface cards designed to facilitate SAN distance extensions via the Alcatel-Lucent
1665 DMX platform using GFP-T (G.7041). These cards employ standard encapsulation, and standard STS-1 and VT virtual concatenation according to ITU G.707. For extended
FC/FICON interfaces, the LNW73/73c also supports buffer_to_buffer credit management spoofing consistent with ANSI T11 FC-BB-3_GFPT draft standard.
They utilize PTM optics to provide the option of FICON, ESCON, or Fibre-channel interfaces natively on the Alcatel-Lucent 1665 DMX shelf. Each circuit pack must be equipped with only one type of PTM (FICON/FC or ESCON). The LNW73/73c can operate at 1 Gbps or 2 Gbps and in either Asynchronous or Synchronous transmission modes. When operating in async Fibre Channel (FC) mode, 2 ports are available at 2Gbps
FC, or 4 ports at 1Gbps FC, or 1 port at 2Gbps FC and 2 ports of 1Gbps FC. When operating in synchronous FC mode, 1 port is available at 2Gbps FC, or 2 at 1Gbps FC.
While the capacity of each port is 2Gbps, the true capacity of each port is relative to the type of PTM it is equipped with. For ESCON traffic, the PTM ports have a capacity of
200 Mbps. The 2Gbps capacity of the ports is sufficient to support FC2G and FICON
Express.
While the LNW73 and LNW73C circuit packs do support LCAS, the LNW73 only uses
LCAS with asynchronous FC traffic.
The LNW73C circuit pack differs from the LNW73 circuit pack in that it enables compression of SAN traffic.
The implementation of SAN compression enables a high throughput of up to two full-line rate FC-2G interfaces in a single pack.
The LNW73C circuit pack is able to compress asynchronous Fibre Channel traffic and conserve up to 50% of bandwidth versus uncompressed asynchronous FC traffic in typical applications.
Compression for asynchronous FC traffic is pre-standard and will be standardized by
FC-BB-4. The R6.0 implementation of SAN compression enables a high throughput of up to two full-line rate FC-2G interfaces in a single pack.
The backplane capacity of the LNW73/73C is 2.5G. When Alcatel-Lucent 1665 DMX is not equipped with VLF Main (LNW59/LNW82/LNW504) circuit packs, the LNW73/73C circuit packs can only occupy slot 1 of any Function or Growth Unit group on the shelf.
When Alcatel-Lucent 1665 DMX is equipped with VLF circuit packs in the Main slots,
FC-DATA circuit packs can occupy both Slot 1 and 2 of a Function or Growth Unit.
When VLF Mains are not used, if the LNW73/73C circuit packs occupy slot 1 of a
Function Unit group, slot 2 must be populated with an apparatus blank.

10/100BASE-T and 100BASE-ZX/LX/FX (LNW74) Fast Ethernet interface
This LNW74 is a 24-port Fast Ethernet Private Line circuit pack. The LNW74 uses standard GFP encapsulation (G.7041) and standard STS-1 and VT virtual concatenation according to ITU G.707. The LNW74 circuit pack provides 8 ports for optical
100BASE-ZX/LX/FX transport at 100 Mbps The LNW74 circuit pack also provides 16 electrical ports for the 10/100BASE-T interfaces. These electrical ports transmit at 10/100
Mbps using standard Ethernet switching IEEE 802.1, standard encapsulation, and standard STS-1 and VT virtual concatenation according to ITU G.707. For specific details about the supported configurations, see
“Ethernet port configurations” (p. A-19) . The
LNW74 circuit pack electrical interfaces can transmit signals across spans as long as 100 meters.
The LNW74 circuit pack is an unprotected circuit pack and is OSP hardened. However, you must install PTMs that are approved for industrial temperatures (OSP hardened) to use the LNW74 in OSP applications. When VLF Mains are not used, if the LNW74 circuit packs occupy slot 1 of a Function Unit group, slot 2 must be populated with an apparatus blank.
The LNW74 circuit pack is designed specifically to support Fast Ethernet Private Line applications. Each LNW74 circuit pack can support 24 private lines. The LNW74 circuit pack can also support STS-3(c) cross-connections instead of virtual concatenation.
The backplane capacity of the LNW74 is 2.5G. When the Main slots are equipped with
VLF circuit packs, LNW74 circuit packs can be installed in either slot 1 or 2 of Function
Unit or Growth groups to support true 0x1 on optical ports. The LNW74 circuit pack can be installed next to another optical TDM or Ethernet circuit pack within the same group.
The LNW74 circuit pack features Pluggable Transmission Module (PTM) optics for all
100BASE-ZX/LX/FX interfaces. PTM optics are "pluggable" in the sense that they can be plugged into a circuit pack as they become necessary. This allows customers to grow their network incrementally, only realizing the full cost for optics as the need to provision service on (and thus receive revenue from) them becomes necessary. LNW74 circuit packs are purchased and shipped with no ports populated with functioning optics. The ports remain empty until the customer decides to place optics in them. 8 ports are available for 100BASE-ZX/LX/FX optics. There are 24 internal WAN ports (capable of transmitting signals to the MAIN circuit packs) in the LNW74 circuit pack.
OC-48 OLIU (LNW76)
The LNW76 high-speed circuit pack is a short-reach, OC-48 1310 nm optical line interface unit. It is designed for intra-office transmission. The LNW76 supports OC-48 add/drop, BLSR, UPSR, and 1+1 configurations, single- and dual-homing, non-revertive linear and bidirectional 1+1 protection switching, and VT1.5, STS-1, STS-3(c),
STS-12(c), and STS-48(c) signal transport. The Stratum 3 timing generator and central
TDM switch fabrics are embedded in the OC-48 OLIU.

The LNW76 circuit pack can cross-connect VTs in all 48 STS-1s of the OC-48 signal.
The LNW76 may occupy Main slots 1 and 2. Fiber access is provided via a pair of
LC-type connectors on the LNW76 faceplate.
Main switch pack (LNW80)
The LNW80 high-speed circuit pack is designed to save cost in CO hub applications where there is no need to transmit traffic over network-side interfaces. LNW80 is best used in a DCS type of application. It can cross-connect signals amongst multiple low-speed tributary interfaces and perform VT mapping into OC-3/12/48 tributaries. It can cross-connect signals at the VT1.5, STS-1, STS-3(c), STS-12(c), and STS-48(c) level. The Stratum 3 timing generator and central TDM switch fabrics are embedded in the LNW80.
The LNW80 circuit pack design is based on the design/capabilities of the LNW27 pack, minus the optical interfaces.
The LNW80 circuit pack supports VT mapping in 96 STS-1s.
The LNW80 may occupy Main slots 1 and 2 and contains NO interfaces on the faceplate of the pack. Due to the increased switch fabric size and the absence of any optics on the pack's faceplate, the LNW80 cannot be upgraded to a high-speed optical pack.
OC-3/OC-12/OC-48 OLIU (LNW82)
The LNW82 high-speed circuit pack is an 8-port, multi-port., multi-rate (MPMR) OC-3,
OC-12, OC-48 VLF Main circuit pack. The pack supports a maximum of 8 OC-3 interfaces, 8 OC-12 interfaces or 2 OC-48 interfaces and has integrated STS and VT fabrics.
Mixed interface rates are supported with the following restrictions.
• OC-48 interfaces are only supported on ports 1 and 5.
• When one of these ports is operating at the OC-48 rate, then the next three adjacent ports cannot be used.
For example, if port 1 is operating as an OC-48 port, then ports 2, 3, and 4 are unavailable for use.
The LNW82 is hardened for outside plant (OSP) temperature ranges. However, you must install PTMs that are approved for industrial temperatures (OSP hardened) to use the
LNW82 in OSP applications.
The pack supports true 0x1 operation for low-speed packs. The backplane interfaces can operate at 2.5 Gb/s or at 622 Mb/s, supporting all VLF-compatible low-speed packs. The
LNW7 circuit pack is not VLF-compatible.

....................................................................................................................................................................................................................................
The overall capacity of the LNW82 is a 10G optical main with 130G of STS switch fabric and 10G VT switch fabric. When the Alcatel-Lucent 1665 DMX is equipped with
LNW82 VLF mains, all switching takes place on the LNW82 circuit packs. The switch fabrics on the low-speed, tributary optical circuit packs are disabled. The LNW82 further upgrades the overall capacity of the shelf by enabling the Function and Growth slots to house circuit packs with up to 10G bandwidth for a total input/output capacity of 110G.
The LNW82 provides increased flexibility for equipping low-speed OC-n interfaces with increased port density. OC-3, OC-12, OC-48, or OC-192 operation can be selected on a per port basis, up to the maximum number of ports supported for each interface type. The supported protection applications (1+1, 1+1_BIDIR, 1+1_OPTM, UPSR, 0x1, and BLSR
[OC-48 only]) can also be provisioned on a per-port basis. The system supports SONET ports on the TDM optical packs. However, the ports are capable of interworking with older SDH interfaces by provisioning the outgoing SS bits to 10. If there is a mismatch in the provisioned (transmitted) SS bits and the received SS bits, an inc. STSN SS Bit Mismatch is declared.
FE/GbE Private Line (LNW87) Ethernet interface
The LNW87 circuit pack is an 4-port, PTM-based Private Line Fast Ethernet/Gigabit
Ethernet pack. The ports can be populated with either, 4 optical, 4 electrical PTMs, or a mix of electrical and optical PTMs. The port mode is provisionable on per port basis. The
LNW87 contains 4 internal VCG ports supporting enhanced Private Line services such as high-order virtual concatenation (VCAT) and Link Capacity Adjustment Scheme (LCAS).
LNW87 supports STS-1 and STS-3c cross-connections with or without VCAT, and
STS-12c cross-connections without VCAT. All ports are capable of transmitting at wire speed (1000 Mbps) simultaneously, making full capacity of the pack 84 STS-1s.
The LNW87 is an unprotected pack. The LNW87 can be used with VLF Mains or non-VLF mains and can occupy both slots 1 and 2 of a Function/Growth unit, making the total capacity of a systems fully populated with LNW87s, 40 GbE Private Line ports. The backplane capacity of the LNW87 is 10G.
The LNW87 is hardened for outside plant (OSP) temperature ranges. However, you must install PTMs that are approved for industrial temperatures (OSP hardened) to use the
LNW87 in OSP applications.

to DS1, DS3, or Ethernet electrical interfaces. LNW94 tests the integrity of electrical cables to both identify where trouble exists and which cables or DSX panels are faulty prior to installation and turn up.
In-service electric continuity test tool (LNW93)
The In-service Electrical Continuity Test Tool (LNW93) test circuit pack is used for upgrades in the Alcatel-Lucent 1665 DMX High-Capacity shelf. An in-service shelf might have a function unit with low capacity DS1 (LNW7) or DS3 (LNW16) packs.
When these packs are upgraded with higher capacity packs (DS1, LNW8/LNW801; DS3,
LNW19B), as part of the upgrade procedure, new DS1 or DS3 connectorized cables are added to the DSX cross-connect frames and to the Alcatel-Lucent 1665 DMX shelf. The
LNW93 pack is used to test out the new wiring without disrupting traffic on the in-service pack.
The LNW93 is very similar to the LNW94 test tool except that it has no backplane connectors for DS1 ports #1–28 or for DS3 ports #1–12. When the LNW93 is plugged in, it makes no contact with the wires on the backplane for those lower ports. Since there is no physical connection, the LNW93 does not interfere with the service of the pack in the other slot of the function unit. The LNW93 tests the integrity of electrical cables to both identify where trouble exists and which cables or DSX panels are faulty prior to installation and turn up of a high density DS1 or DS3 circuit pack.
Detectable blank circuit packs
Alcatel-Lucent 1665 DMX supports detectable blank circuit packs: LNW98 in unequipped Function and Growth slots, LNW97 in an unequipped M2.
The WaveStar
®
CIT reports the presence of a detectable blank in a slot by displaying a blank faceplate graphic instead of an empty slot graphic. No alarms are associated with the insertion or removal of the detectable blank.
100/1000BASE-X/T (LNW170) switched Ethernet interface
The LNW170 circuit packs provide four IEEE 802.3-compliant (1000Mbps) GbE interfaces and four IEEE 802.3-compliant (100 Mbps) fast Ethernet interfaces. The
LNW170 circuit packs provide Ethernet private line or switched services, with QoS.
The LNW170 packs feature Pluggable Transmission Module (PTM) electrical and optical interfaces. PTMs are "pluggable" in the sense that they can be plugged into a circuit pack as they become necessary. This allows customers to grow their network incrementally, only realizing the full cost for optics as the need to provision service on (and thus receive revenue from) them becomes necessary.

....................................................................................................................................................................................................................................
The LNW603 may occupy any Function Unit group on the Alcatel-Lucent 1665 DMX shelf (including Growth slots), and up to 10 ports are addressable when all Function Unit slots are equipped with the LNW603 circuit pack.
XM10G/8 muxponder pack (LNW705)
The LNW705 XM10G/8 Muxponder circuit pack is a highly integrated pack that multiplexes up to 8 ports of the most common high bandwidth client interfaces onto a single 10G wavelength. The circuit pack name is XM10G/8: the “X” indicates that the client ports can be SONET/SDH, 1GE or Fibre Channel type interfaces; the “M” represents multiplexer; the “10G” represents the 10G line-side interface; the “8” represents the 8 client ports.
The XM10G/8 circuit pack is 25 mm wide and transports up to 8 client ports. The ports can be a mix of the following signals: 1GE, FC100, FICON, FC200, FICON_EXP, or
OC3/12/48. One GE is mapped using VCAT and GFP-F. All FC signals and FICON signals are mapped using VCAT and GFP-T. The client signals are mapped into a single
STS-192 and then encoded into an OTN OTU-2 signal (including forward error correction) and is transmitted out on a DWDM XFP. The circuit pack is bi-directional and simultaneously handles the inverse function in the receive direction.
The circuit pack faceplate is equipped with standard LED indicators; 1 fault LED, 1 active LED, and 1 LED for each port.
The LNW705 must be installed in a shelf with an LNW2 and at least one Main pack
(VLF or non-VLF).
The LNW705 may occupy any Function Unit or Growth slot on the Alcatel-Lucent 1665
DMX shelf.
Beginning in Release 9.1, the Forward Error Correction (FEC) mode for an OTU2 port is provisionable. Valid values are:
• EFEC: Enhanced Forward Error Correction (default)
• NOFEC: No Forward Error Correction
• RSFEC: Industry-standard Reed-Solomon Forward Error Correction
OMD5/8 DWDM Mux/Demux (LNW785)
The LNW785 circuit pack provides optical multiplexing and demultiplexing of 8 dense-wavelength-division-multiplexed (DWDM) channels (ITU-T channels 52 through
59 [195.20-195.90 THz]). The LNW785 circuit pack has variable optical attenuators
(VOAs) on the inputs for individual channel-power control. It can perform automatic channel power balancing of the add channels via the VOAs.

....................................................................................................................................................................................................................................
The LNW785 circuit pack allows Alcatel-Lucent 1665 DMX to have channel-powermanaged DWDM within the shelf. The LNW785 circuit pack can be installed in any
Alcatel-Lucent 1665 DMX function or growth slots. A one-channel system can be upgraded to an 8-channel-capable system by installing one or more LNW785 circuit packs into any open function or growth slot.
The LNW785 circuit pack requires the use of extended shelf covers for Alcatel-Lucent
1665 DMX shelves, which provide 25-mm additional clearance (67-mm total) as opposed to the current shelf covers. This is because additional clearance is required to angle the multiple connectors on this card.
The LNW785 circuit pack is the first Alcatel-Lucent 1665 DMX circuit pack with intra-shelf fiber routing. Special short jumpers are used to connect pass-through channels when two LNW785 circuit packs in adjacent slots are used as an optical add-drop multiplexer (OADM).
The LNW785 must be installed in a shelf with an LNW2 and at least one Main pack
(VLF or non-VLF).
Optical cross-connections
The following 1-way optical cross-connections are supported on the OCH interfaces of the LNW785 series.
• OCH to/from OCH pass-through cross-connections
• OCH to/from OTU2 add/drop cross-connections
• OCH to/from OC-192 Line add/drop cross-connections
• OCH to/from Alien (remote shelf) add/drop cross-connections
For cross-connections to or from OCH ports, the NE checks that the expected frequency of the port to which the OCH is cross-connected matches the frequency of the OCH port.
However, frequency matching is not required on cross-connections between an OCH port and an alien port.
FE/GBE/10GBE Ethernet pack (LNW910)
The LNW910 FE/GBE/10GBE circuit pack is 25 mm wide and transports up to 10
SFP-based optical or electrical GbE/FE ports and one XFP-based 10GbE port. The supported PTM rates include, 100/1000BASE-T (industrial temp), 100BASE-LX,
1000BASE-SX/LX/ZX, and 10GBASE-LR/ER/ZR, The LNW910 must be installed in a shelf with an LNW2 and at least one VLF Main pack. The pack can support up to 64
VCGs, aggregate packet processing capacity of 20 Gbps, and MEF E-Line and ELAN operation.
In unprotected mode, LAGs can be created from 2 FE/GE ports on the pack. In protected mode, LAGs are automatically created for ports 1–10. If required, the user can provision a LAG on port 11 (10GbE port).

The LNW910 may occupy any Function Unit or Growth slot on the Alcatel-Lucent 1665
DMX shelf.
Cable management bracket
In the interest of helping customers organize the physical networking in their offices,
Alcatel-Lucent 1665 DMX provides two types of fiber management brackets that mount to the apparatus blanks used in the unoccupied slots of the shelf. These brackets have LC fiber storage ports where fibers can be set until the pack to which they will be attached is installed. One bracket has 16 hooks and the other has 24 hooks.
The bracket is designed to facilitate the organization and storage of pre-wired fibers that are expected to carry service to the shelf in the future. These brackets attach to the apparatus blanks via PEM nuts on the faceplate. PEM Nuts or PEM Fasteners are mounted flush on the faceplate. They provide a fixed receptacle to which the bracket can be screwed in.
Passive optics units (POUs)
Passive optics units
The Passive Optics Units (POUs) are a lower-cost solution to using DWDM for transmitting large amounts of traffic on one fiber. The shelf fits in a bay frame with
Alcatel-Lucent 1665 DMX. If the POU is used in the same bay frame with Alcatel-Lucent
1665 DMX, then the number of Alcatel-Lucent 1665 DMX shelves in that bay frame is limited to three. The POUs do not need any power supply or management system.
POU shelves are available to support the following applications:
• Dual optical add-drop module (OADM): 1, 2, or 4 wavelengths
• Dual optical add-drop module (OADM): one 1310 nm port and four 1550 nm ports
• 16 unidirectional/bidirectional wavelengths: MUX or DMUX
• 32 wavelengths using 16 unidirectional/bidirectional wavelengths (MUX or DMUX) with a wavelength interleaver used to add another 16 wavelengths: MUXINT or
DMUXINT

Important! The last four bulleted items in the list above describe the various OADMs and MUX/DMUX as "Dual". "Dual" is in reference to the fact that each of these specific POUs are comprised of two complete sets of OADMs or MUX/DMUX units.
Thus, the dual 1-channel OADM POU contains 2 OADMs, enabling it to support 1 add/drop in each direction.
The following figure shows a diagram of transmission with up to 32 wavelengths
(channels) being received and passed-through one of the Add/Drop units. Also, the diagram shows how 1, 2, or 4 wavelengths can be added and/or dropped from a passive

External optical amplifiers
Overview
The Alcatel-Lucent external optical amplifier provides service providers, system integrators, and network equipment manufacturers with one of the key technologies needed to build next generation DWDM and OADM networks. With the optical amplifier, operators enhance system performance while minimizing capital expenditures.
The optical amplifier can be configured to provide variable gain between 13 dB and 22 dB. This enables users to optimize optical transmission performance as needs grow. After gain setting is provisioned, the amplifier dynamically controls and maintains signal levels even as the number of amplified wavelengths change.

Interfaces
The optical amplifiers provide a 10/100 Mbps and an RS-232 port for operations and maintenance communications (similar to Alcatel-Lucent 1665 DMX). The optical amplifier continuously monitors its own electrical and optical performance. If operating parameters exceed user-specified thresholds, autonomous alarms are reported.
The optical amplifier may be managed by any of the following means:
• Simple Network Management Protocol (SNMP Version 1 and 2c)
• TL1 messages (GR-833 CORE)
• File Transfer Protocol (FTP) (RFC 956)
• Alarm relay contact closures.
For more information about the Alcatel-Lucent external optical amplifiers, consult your account executive.
Control
Overview
Alcatel-Lucent 1665 DMX provides extensive control features, accessible through a number of technician and operations system (OS) interfaces. In addition to accessing local Alcatel-Lucent 1665 DMX NEs through direct interfaces, technicians and OSs can use the operations features supported via the DCC in the optical signals to access remote
NEs. Control functions are supported by the SYSCTL circuit pack.
Three-tiered operations interface
Alcatel-Lucent 1665 DMX maintenance procedures are built on three levels of system information and control. The first tier is provided by the LEDs, displays, and push-button switches located on the faceplate of the SYSCTL circuit pack. The second tier uses
WaveStar
®
CIT to provision and retrieve detailed reports of performance monitoring, alarm and status, and system configuration for both local and remote NEs. The third tier uses the OS interfaces such as TL1 and TL1 over IAO LAN (TCP/IP or OSI) or CIT to monitor performance, gather alarm information, and configure the system. Also, the IAO
LAN interfaces provisioned for TCP/IP support software download and provisionable database backup/restore via FTP.
SYSCTL faceplate
The faceplate of the SYSCTL circuit pack contains indicators that provide system-level information and control functions. The condition of the individual transmission circuit packs can be determined using faceplate LEDs.

The figure on the following page, shows the SYSCTL faceplate. There is a 35-segment numeric LED display and three push-button switches for Update/Initialize (UPD/INIT),
ACO/test (ACO/TEST), and Select (SEL) for local operations.
LNW2 comes equipped with two removable Non-volatile Memory (NVM) cards that can also be ordered separately. The Alcatel-Lucent 1665 DMX shelf will only function properly when it is equipped with an LNW2 that contains two fully functioning NVM cards.
In addition to the Active and FAULT LED, there are also seven alarm/status LEDs on the
SYSCTL faceplate, listed below. The FAULT LED is lit if the SYSCTL detects its own failure:
• Critical (CR)
• Major (MJ)
• Minor (MN)
• Abnormal (ABN)
• Far End Activity (FE)
• Near End Activity (NE)
• Alarm Cut-Off (ACO)

SYSCTL faceplate (operations level 1)
Office alarms are provided by a set of discrete relays that control office audible and visual alarms. Separate relays handle critical (CR), major (MJ), and minor (MN) alarms, although the CR and MJ alarms can be wire ORed and reported as office major, if desired.
The light-emitting diodes (LEDs) and push buttons on the SYSCTL faceplate allow routine tasks to be performed without a CIT or any test equipment. The SYSCTL faceplate LEDs provide system-level alarm and status information for the local NEs and a summary for all remote NEs in the alarm group. The circuit pack faceplate FAULT LEDs allow fast and easy fault isolation to a particular circuit pack.
The SYSCTL faceplate LEDs default to show local system information. The highest active alarm level is shown by the red LEDs for CR and MJ alarms. Yellow LEDs are shown for MN alarms. An ACO button is used to activate the alarm cutoff function. When activated, the LED is on. The ACO button also initiates an LED test when the button is depressed and held. A green PWR ON LED shows that the power is on and the terminal is receiving a −48V source. Three yellow status LEDs show abnormal (ABN) conditions,

near-end activity (NE), and far-end activity (FE). The yellow ABN LED is lighted when a temporary condition, potentially affecting transmission, exists. For example, this condition could be a manual protection switch or lockout, loopback, or system test in progress.
The Update/Initialize (UPD/INIT) button addresses the local system. The recessed
UPD/INIT button serves several functions during installation and circuit pack replacement. During the first 10 seconds after powering up the SYSCTL circuit pack, depressing this button initializes the nonvolatile memory with provisioning and state information. Secondly, after removing a circuit pack, optical module, or low-speed input, depressing this button updates the system equipment list to show the slot, socket, or signal is now unequipped.
The SYSCTL faceplate's remote display functions serve the single-ended maintenance needs of access transport applications. When any alarm or status condition exists at a remote Alcatel-Lucent 1665 DMX shelf in the same alarm group, the FE LED on the faceplate is lit.
The table below details the various LEDs and push-button switches and describes their functions.

Circuit pack LEDs
To supplement the SYSCTL faceplate's system-level view, each circuit pack provides a red FAULT LED on its faceplate. A lighted FAULT LED shows that the Alcatel-Lucent
1665 DMX has isolated a failure to that circuit pack. On transmission circuit packs, a flashing FAULT LED shows that an incoming signal to that circuit pack has failed.
Important! All circuit packs that use PTM optics have per-port LEDs. The per-port
LED is lit solid if there is a socket failure, and blinks if there's an incoming port
(signal) failure.
Local craft interfaces (operations level 2)
The local craft interfaces include the CIT, which may be utilized in a variety of ways.
Alcatel-Lucent 1665 DMX has two serial ports for CIT access, one in the front and one at the rear of the shelf.
TL1 is supported for both serial ports, but software download is supported via the front serial port only.
Alcatel-Lucent 1665 DMX also has two LAN ports for CIT (and/or OS) access, one in the front and one in the rear. Both TL1 over OSI and TL1 over TCP/IP are supported via these two LAN ports. Software download via FTAM or FTP and FTTD are also supported.
Remote Operations System (OS) TL1/LAN interfaces (operations level 3)
The third operations level consists of the remote access to OS interfaces. Access for TL1 and related SONET network monitoring is provided via the CIT LAN and serial connection to the SYSCTL.

TL1
The TL1 message-based OS interface provides remote OS access, as well as detailed reporting and control capabilities. The interface uses standard TL1 and needs no mediation device (i.e., the interface can be connected directly). The remote user could be an OS or a user at a terminal. Alcatel-Lucent is involved in an active OSMINE process to ensure compatibility of Alcatel-Lucent 1665 DMX NEs with Telcordia
®
OSs.
Alcatel-Lucent 1665 DMX supports TL1 alarm surveillance and performance monitoring with OSs such as Telcordia
®
Network Monitoring and Analysis (NMA). Alcatel-Lucent
1665 DMX supports service provisioning with memory administration OSs such as
Alcatel-Lucent's OMS or Telcordia
®
TEMS. Alcatel-Lucent 1665 DMX also supports remote recovery and control functions, installation provisioning, and security over the
TL1 link. The TL1 message set used has been updated to offer full remote reporting capabilities.
The OS can use more than one NE as a GNE to provide redundancy and/or to distribute
TL1 message volume. The TL1 GNE serves as a single interface to the OS for the NEs in the same subnetwork. The TL1 GNE receives operations information from all the NEs through the DCC and reports this information, as well as its own information, to the OS.
The operations information is in the form of TL1 messages. Through the GNE, the OS can send TL1 commands to any NE in the subnetwork. Alcatel-Lucent's OMS, as well as other-vendor NEs that adhere to GR-253-CORE, can serve as the TL1 GNE for the
Alcatel-Lucent 1665 DMX.
CIT (TL1 over TCP/IP)
The CIT is a small CIT interface that provides a flexible TL1 command instructor. The
CIT connects to an Alcatel-Lucent 1665 DMX using either the front or rear serial ports, the front IAO LAN port, or the rear IAO LAN port. The CIT supports TCP/IP (or OSI) through both the front and rear IAO LAN interfaces.
The CIT is used for report generation, as well as command and system response. Access to the system is provided via serial or IAO LAN interfaces.
Front IAO LAN
The front IAO LAN interface provides a connection to the CIT and supports OSI or
TCP/IP communications. The front IAO LAN is located on the faceplate of the SYSCTL circuit pack.
Rear IAO LAN
The primary purpose of the rear IAO LAN port is to provide remote OS access such as
OS TL1 access over TCP/IP Gateway. It also supports a faster software download from any FTP server using file transfer protocol (FTP) to Alcatel-Lucent 1665 DMX systems when software is being upgraded (both the rear and front IAO LAN ports support this functionality). This rear IAO LAN port can also be used for CIT OSI-based interfaces and
TCP/IP support.

IAO LAN ports (detail)
Overview
Alcatel-Lucent 1665 DMX supports a front and rear IAO LAN port. Each IAO LAN port operates independently (Alcatel-Lucent 1665 DMX does not support an internal IAO
LAN hub). The front IAO LAN port is recommended for convenient, temporary local
WaveStar
®
CIT access. When, for example, the WaveStar
®
CIT is directly connected to either IAO LAN port, a LAN crossover cable is required (to connect the transmit wire-pair at one end to the receive wire-pair at the other end, and vice versa).
The rear IAO LAN port is recommended for permanent local WaveStar
®
CIT access and all remote WaveStar
®
CIT access via TCP/IP as well as for OS access. Alcatel-Lucent
1665 DMX's rear IAO LAN port is typically expected to be connected to an Ethernet
LAN hub in CO applications, but unused at remote sites.
The Alcatel-Lucent 1665 DMX IAO LAN ports support 10/100BaseT Ethernet (per
Telcordia
®
GR-253, ANSI/IEEE 802.2 and 802.3, and ISO 8802.2 and 8802.3) over four-wire twisted pair using an RJ-45 connector. Each IAO LAN port automatically adapts its rate to 10 Mb/s or 100 Mb/s to match the capability of the other nodes on the same IAO LAN, with 10 Mb/s as the default rate.

OSI on the IAO LAN
When the OSI protocol stack is used on an IAO LAN port, the term "OSI LAN" is sometimes used. The OSI LAN is effectively an extension of the DCC. All remote operations supported over the DCC are also supported over the OSI LAN. The term
"DCC connectivity" is used throughout this document to mean DCC and/or OSI LAN connectivity.
OSI communications on the IAO LAN port can be enabled or disabled. By default, OSI is enabled on the front IAO LAN port, but disabled on the rear IAO LAN port.
TCP/IP on the IAO LAN
The IAO LAN ports also support the TCP/IP protocol stack. TCP/IP communications on the IAO LAN ports can be enabled or disabled. By default, TCP/IP is disabled on the IAO
LAN ports.
When the TCP/IP protocol stack is used on an IAO LAN port, the term "TCP/IP LAN" is sometimes used.
Alcatel-Lucent 1665 DMX supports TL1 over TCP/IP for the IAO LAN. As a TL1 responder, the Alcatel-Lucent 1665 DMX TCP/IP GNE accepts incoming TL1 connections to the following TCP ports with corresponding TL1 code.
• FTP: user-provisionable, default port 21
• SSH FTP: user-provisionable, default port 22
• SNMP traps: 162 NTP: port 123
• RADIUS: user-provisionable, default port 1812
• Port 3081: Length-Value Encoding. With length-value encoding,each TL1 message is encapsulated into the TCP data stream as follows:
– Version number (1 byte, value set to 3)
– Reserved (1 byte, value set to 0)
– Length (2 bytes, value set to length in bytes of TL1 message + 4)
– TL1 Message (variable length)
The length-value encoding is the preferred encoding for machine-machine interactions.
• Port 3082: Raw Encoding. Each raw encoded TL1 message is encapsulated into the
TCP data stream of length 1–4096 bytes. The TL1 message must be parsed to find the boundary between successive TL1 messages (see Telcordia
®
GR-831 CORE for the syntax of TL1 messages).
• Port 3083: Telnet Encoding. The telnet encoding is a variation on the raw encoding. It encapsulates TL1 messages in a TCP stream and uses Telnet for transmitting text over
TCP/IP.

Operations philosophy
Overview
Alcatel-Lucent 1665 DMX has incorporated an operations philosophy that is optimized for operations in the access transport environment. This allows operation and maintenance of remote NEs from a single location. Similarly, a technician working at a remote site can gain access to other NEs. In addition, OSs are available to allow operation of the Alcatel-Lucent 1665 DMX NEs from a centralized operations center.
Alcatel-Lucent 1665 DMX uses the SONET data communications channel (DCC) to provide remote CIT access, remote CO alarms, remote alarm reports, and remote OS access. The terms remote operations, single-ended operations (SEO), and Operations
Interworking (OI) are synonymous.
SEO capability
The figure below shows the SEO capability that provides remote access to all
Alcatel-Lucent 1665 DMX systems in a subnetwork from a single Alcatel-Lucent 1665
DMX location. This minimizes the need for technician travel because most maintenance,

Alarm groups
An alarm group is a set of NEs that share status information between themselves, such as alarms, LEDs, and ACO status. The set of remote NEs that an NE can exchange status information which is determined by the value of the local alarm group parameter. This parameter is provisioned at each local NE and specifies whether that local NE does or does not exchange remote NE status with other Alcatel-Lucent NEs in the same SONET subnetwork. In Alcatel-Lucent 1665 DMX, all NEs are defaulted into the same alarm group (number 255).

....................................................................................................................................................................................................................................
Alarm groups can be nodes in a ring, nodes of a linear extension, or any other logical grouping such as a maintenance group or geographical group. For example, 24 NEs could be provisioned into three alarm groups with eight NEs that share a community of interest such as the same OC-3 low-speed optical interface.
All members of the same alarm group share NE status information but do not share information with other alarm groups.
Alarm group functions
Depending on provisioning, a member of an alarm group can:
• Know the alarm/status of all members of the same alarm group and, if the NE is at the
CO, activate audible office alarms for the alarm group.
• List a report of the summary alarm or status condition of other NEs in the group.
• Display composites of the highest alarm level among other member NEs in the same alarm group.
Alarm Gateway Network Element (AGNE)
Members of an alarm group exchange information through one or more alarm gateway
NEs (AGNEs) that are defined in the same alarm group. All Alcatel-Lucent 1665 DMX
NEs use the DCC to receive and report alarm and status information to the AGNE(s). The
AGNE rebroadcasts all alarm and status information from one NE to all the other NEs in the same alarm group.
This information is used to activate remote far-end summary alarm reports and remote office alarms for each NE in the alarm group. At least one NE in each alarm group must be provisioned as the AGNE. An additional AGNE can be provisioned for redundancy, but it is recommended that only one AGNE be provisioned for each alarm group.
Considerations for choosing an NE as an AGNE include being central to the group to make communications links easily accessible for maintenance purposes.
The AGNE and TL1 GNE should be separate NEs. Furthermore, the AGNE is a
"collection point" and does not have to be a NE in a CO.

To support multi-vendor OI, the Alcatel-Lucent 1665 DMX supports Target ID Address
Resolution Protocol (TARP).
TARP provides NSAP-TID translations and is the established multi-vendor standard for
SONET NEs that support TL1 OS interfaces. Alcatel-Lucent 1665 DMX supports the
TARP Data Cache (TDC) function to reduce the frequency of TARP propagation throughout the subnetwork and to improve performance.
Compatibility
Alcatel-Lucent 1665 DMX is developed to be compatible with any other-vendor NEs that support TARP, OSI, IAO LAN, and TL1 as specified in Telcordia
®
GR-253. In addition,
Alcatel-Lucent 1665 DMX's TARP Manual Adjacency feature enables it to operate in networks that include CMISE-based NEs which may not support TARP propagation.
Alcatel-Lucent 1665 DMX supports user provisioning of several OSI parameters to allow users to adjust their operations network, if necessary. For example, to support Level 2
Routing in large networks, Alcatel-Lucent 1665 DMX supports user provisioning of
NSAP area addresses and Level 2 Intermediate System (IS) functionality.
Alcatel-Lucent 1665 DMX's compatibility with other-vendor NEs may be tested by customers or independent third parties such as Telcordia
®
.
Data Communications Channel (DCC)
Provisioning the DCC
To support remote operations over the DCC embedded in the SONET section overhead of the optical signal, the DCC itself must be provisioned as indicated in the following paragraphs.
DCC enable/disable
By default, the DCC is enabled on all optical ports. DCC communications can be enabled or disabled on each port independently.
DCC protection mode
The DCC protection mode is determined by the transmission protection mode assigned to each optical port (per the application parameter). The protection mode can be linear (1+1) identical, or distinct (UPSR). Linear (1+1) identical is the default for the low-speed optical ports. Support is provided for 15 low-speed OC-48 BLSRs.

For complete coverage of Alcatel-Lucent 1665 DMX's software download procedures, see the Alcatel-Lucent 1665 Data Multiplexer (DMX) User Operations Guide,
365-372-301.
Local software download
Alcatel-Lucent 1665 DMX supports the following local software downloads.
• Local software installation via File Transfer Protocol (FTP) from a WaveStar
®
CIT connected to the
CIT LAN
(IAO LAN) port on the SYSCTL circuit pack faceplate or the
J16 IAOLAN
(IAO LAN) port on the shelf backplane. Software installation via
FTP requires the following:
– FTP Client software is enabled on the NE
– IP parameters are provisioned on the NE.

Software download (generic)
....................................................................................................................................................................................................................................
Important! FTP must be used to install software when using the Microsoft Windows
®
XP Operating System.
Operating software for Alcatel-Lucent 1665 DMX can be downloaded or upgraded remotely over the data communications channel or the operations network.
Via the DCC
Software and software upgrades can be downloaded to remote NEs from a central office site or any Alcatel-Lucent 1665 DMXtend/Alcatel-Lucent 1850 TSS-5 connected to the
Alcatel-Lucent 1665 DMX via the data communications channel (DCC).
Remote software download
Remote software download reduces the need to travel to remote sites when the software version of multiple Alcatel-Lucent 1665 DMX systems is being upgraded throughout a network.
• Beginning in Release 9.0, remote software installation via SSH File Transfer Protocol
(SFTP). SFTP is a new protocol defined by IETF which runs over a secure SSH channel and provides secure file transfers. Network configurations, user names, passwords, FTP commands and transferred files are protected.
• Remote software download via an FTAM-FTP gateway to Alcatel-Lucent 1665 DMX.
The FTAM-FTP gateway is also referred to as the file transfer translation device
(FTTD).
• File Transfer Protocol (FTP) from the WaveStar
®
CIT over the IAO LAN connected to the LAN port on the SYSCTL. This requires that FTP is enabled on the NE, and that IP is enabled and properly configured on the SYSCTL LAN port.
• File Transfer and Access Management (FTAM) protocol from the WaveStar
®
CIT over the IAO LAN connected to the LAN port on the SYSCTL. You must have OSI connectivity (via your OSI LAN or DCC) to the network element to use FTAM.
• FTTD (FTAM-FTP gateway) without TCP/IP connectivity.
• Software copy from the local Alcatel-Lucent 1665 DMX to a remote Alcatel-Lucent
1665 DMX.
Software copy from the local Alcatel-Lucent 1665 DMX to a remote:
– Alcatel-Lucent 1665 DMX
– Alcatel-Lucent 1665 DMXtend
– Alcatel-Lucent 1665 DMXplore
– DDM-2000 OC-3
– DDM-2000 OC-12
– FiberReach
Important! The software must be in the dormant area of Alcatel-Lucent 1665 DMX.
Both the local and remote NEs must have an active software generic.

Impact of software download and activation
Initial local software installation temporarily disrupts operations communications because the system controller is reset to activate the software immediately.
Other local software downloads temporarily disrupt operations communications, too, because a system controller reset is involved, but the dormant software is not activated immediately.
Remote software download or copy of compressed dormant software is accomplished without any disruption of operations communications (that is, no system controller resets), because the dormant software is not activated immediately.
If there is no valid generic or database on the controller, or if there are multiple valid generics or databases when the shelf resets, the shelf enters maintenance mode, using the default database. If necessary, the WaveStar
®
CIT wizard will guide the user through the download/restore process and prompt generic and database selection.
Remote software download compatibility
The following list identifies the products to which you can perform remote software downloads using the WaveStar
®
CIT connected to Alcatel-Lucent 1665 DMX.
• Alcatel-Lucent 1665 DMX
• Alcatel-Lucent 1665 DMXplore
• Alcatel-Lucent 1665 DMXtend
• Alcatel-Lucent 1850 TSS-5
• DDM-2000 OC-3
• DDM-2000 OC-12
• FiberReach
Important! Alcatel-Lucent 1665 DMX shelves running pre-R6.0 software releases can only perform downloads to other pre-R6.0 Alcatel-Lucent 1665 DMX or other pre-R4.0 Alcatel-Lucent 1665 DMXtend. Any shelf running R6.0 and later releases can download previous releases.
Digital signature capability
Alcatel-Lucent 1665 DMX can verify software downloads using a digital signature. When
FTP over TCP/IP is used for a software download, a digital signature is transmitted with the software download and verified by the network element. If the verification fails,
Alcatel-Lucent 1665 DMX reports an autonomous message and the software download fails. The digital signature is discarded after verification.
Checking the digital signature of software download can be enabled or disabled using the
Configuration
→ Software → Software Download command.

Database backup and restore
Overview
This section describes the database backup and restore feature in Alcatel-Lucent 1665
DMX. IP tunneling is required to support remote database backup/restore for remote
Alcatel-Lucent 1665 DMX systems.
Alcatel-Lucent 1665 DMX uses the following connections to perform database backup and restore:
• A direct IP connection
• OSI connectivity to an FTP GNE.
• FTAM Backup and Restore
Database backup
Alcatel-Lucent 1665 DMX can back up all provisionable data via a local or remote FTP file transfer. Data can be backed up to a remote operations system via an FTAM-FTP gateway. The FTAM-FTP gateway is also referred to as the file transfer translation device
(FTTD).
The backup database is stored on a WaveStar
®
CIT, and OMS, or another FTP server. For information about the
Configuration
→ Software → Remote Backup command, see the
WaveStar
®
CIT help.
Database restore
In the event of a catastrophic failure, Alcatel-Lucent 1665 DMX can restore all provisionable data (from the backup file) via local or remote FTP. Data can be restored from a remote operations system via an FTAM-FTP gateway. The FTAM-FTP gateway is also referred to as the file transfer translation device (FTTD).
The backup database maybe stored on a WaveStar
®
CIT, and OMS, or another FTP server. For information about the
Configuration
→ Software → Remote Restore command, see the WaveStar
®
CIT help. For more information about restoring the network element database, see the Alcatel-Lucent 1665 Data Multiplexer (DMX) User
Operations Guide, 365-372-301.
Automatic database backup
Alcatel-Lucent 1665 DMX supports automatic database backups. This allows users to establish a backup interval, date, and time. The database backups may be saved on the
WaveStar
®
CIT or another FTP server.

The user can also specify the number of backups to destination files before overwriting those same files with subsequent backups. To eliminate the scenario of multiple
Alcatel-Lucent 1665 DMX systems initiating automatic backups simultaneously,
Alcatel-Lucent 1665 DMX does not support a default scheduled backup date/time; the user must provision their own date/time. For information about the

Maintenance signaling
Compliance
Maintenance signaling is compliant with SONET (Telcordia
®
GR-253) and asynchronous (Telcordia
®
TR-TSY-000191) network requirements. Alarm indication signals include SONET OC-n line AIS, STS-1 path AIS, virtual tributary (VT) path AIS,
DS3 AIS, and DS1 AIS. Remote defect indication signals include STS-1 path RDI and
VT path RDI. Other maintenance signals include STS-1 path unequipped, VT path unequipped, Loss of Signal (LOS, Loss of Frame (LOF), and Loss of Pointer (LOP).
Fault detection, isolation, and reporting
Overview
Alcatel-Lucent 1665 DMX continuously monitors incoming signals and internal system conditions.
Incoming signals
Incoming signals are monitored at the line level for loss of signal (LOS), loss of frame
(LOF), and Alarm Indication Signal (AIS), and BER threshold crossings. Incoming signals are monitored at the path level for loss of pointer (LOP), Alarm Indication Signal
(AIS), unequipped (UNEQ), and BER threshold crossings.
At the OTS and OCH levels, Alcatel-Lucent 1665 DMX monitors for and reports on loss of signal - path (LOS-P) alarms.
At the OTUk level, Alcatel-Lucent 1665 DMX monitors for and reports on loss of signal path (LOS-P), backward defect indicator (BDI), signal Degrade (DEG), loss of frame
(LOF), loss of multiframe (LOM), and server signal failed (SSF) alarms. (AIS is not reported as the reported SSF is sufficient.)
At the ODUk level, Alcatel-Lucent 1665 DMX monitors for and reports on backward defect indicator (BDI), signal Degrade (DEG), locked (LCK), open connection indication
(OCI), and server signal failed (SSF) alarms. AIS is detected but not reported.

The BER threshold crossings are detected for DS1, DS3, E1, EC-1, VT1.5, OC-3, OC-12,
OC-48, OC-192, STS-1, STS-3c, STS-12c, STS-48c, and STS-192c signals.
Fault detection
In addition to detecting line and path faults, the system also detects internal circuit pack faults. When an internal fault is detected, automatic diagnostics isolate the faulty circuit pack. Faults are reported to local technician and OSs so that technician dispatch and repair decisions can be made. If desired, OS personnel and local technicians can use the
CIT to gain more detailed information on the fault condition.
Fault isolation
All detected fault conditions are stored and are available to be reported on demand. In addition, a history of past alarm and status conditions and events is maintained and available for on-demand reporting. Each event is real-time and date stamped.
Fault reporting
Alcatel-Lucent 1665 DMX reports all detected alarm and status conditions through the appropriate office alarm relays, SYSCTL faceplate LEDs, transmission circuit pack
LEDs, and TL1 interfaces.
Alarm masking
In order to minimize the number of alarm conditions reported by the NE, Alcatel-Lucent
1665 DMX automatically masks (suppresses the reporting of) alarms of the same root cause. Alarms/status conditions of the same root cause are arranged in a hierarchical order. When more than one alarm or status condition in a hierarchical group exists in a single NE, only the top level condition in that hierarchy is reported.
Loopbacks and tests
Overview
Alcatel-Lucent 1665 DMX allows technicians to perform loopback tests on all low- and high-speed interfaces. Low-speed DS1, DS3, E1, and EC-1 electronic loopbacks, directed toward the high-speed line (terminal loopback), are individually controllable from the
CIT or the OS interface. Active electronic loopbacks are shown by the ABN LED on the
SYSCTL faceplate and in the alarm and status report. EC-1, E1, DS1, DS3, and Ethernet facility loopbacks toward the DSX are also available.
Optical loopbacks
Alcatel-Lucent 1665 DMX supports facility, terminal and manual optical loopbacks.

Loopbacks and tests
....................................................................................................................................................................................................................................
Facility loopbacks
Alcatel-Lucent 1665 DMX supports facility optical loopbacks on high-speed
OC-3/12/48/192 ports and low-speed OC-3/12/48/192 ports.
Terminal loopbacks
Alcatel-Lucent 1665 DMX supports facility optical loopbacks on high-speed
OC-3/12/48/192 ports and low-speed OC-3/12/48/192 ports.
Manual loopbacks
Front access to the optical connectors on the optical line interface unit (OLIU) circuit pack allows easy manual optical loopback. This loopback is performed by connecting a fiber jumper from the OLIU circuit pack output to its input. In some cases a lightguide build-out assembly is required to prevent receiver overload when performing loopbacks.
DS1, E1, DS3 loopbacks
Alcatel-Lucent 1665 DMX supports terminal and facility loopbacks on DS1, E1 and DS3 interfaces.
Ethernet loopbacks
Beginning in Release 9.1, Ethernet loopbacks are allowed even when Remote Client Fail
(RCF) or Far End Failure Indicator (FEFI) is active.
Ethernet terminal loopbacks
Alcatel-Lucent 1665 DMX supports terminal loopbacks on all Ethernet interfaces.
Ethernet facility loopbacks
Alcatel-Lucent 1665 DMX supports facility loopbacks on the LNW78 and LNW170.
Facility loopbacks are supported on both individual ports and Link Aggregation Groups
(LAGs). Loopbacks on LAGs are permitted simultaneously for both ports in the group because they are treated as failed members allowing transmission on unlooped members.
If a facility loopback is set up on a LAG, alarms are suppressed on both the member ports and the LAG.

State check before loopback
Beginning in Release 9.1,
ENT-SYS
supports a new parameter, loopback port check
(lpbk_port_ck). The parameter controls how loopbacks are handled for PDH, EC1 and
Ethernet ports based on the state of those ports.
• DISABLE (default): The execution of loopbacks for PDH, EC1 and Ethernet ports ignores the value of cmdmode in
OPR-LPBK
.
• ENABLE: The execution of loopbacks for PDH, EC1 and Ethernet ports is a function of the respective port’s primary state and the value of cmdmode in
OPR-LPBK
. If
cmdmode=NORM, the loopback is denied unless the port is out of service. If
cmdmode=FRCD, the loopback executes irrespective of port state.
Note: This parameter does not affect loopback operation for OC-n lines.
Internal testing capabilities
Technicians can use the internal testing capabilities for installation and manual troubleshooting. The DS1 and DS3 test signal generators and detectors are integrated into the system, eliminating the need for external test equipment to perform transmission tests.
Specific testing
Alcatel-Lucent 1665 DMX also allows technicians to test specific system components. In addition to the automatic diagnostics, Alcatel-Lucent 1665 DMX provides tests for LEDs, office alarms, and the SYSCTL circuit pack.
Test access
Overview
Test access, a traditional DCS function, allows the user visibility into any VT1.5/STS-1 signal in the network. Test access aids users in turning up connections and in identifying faults in existing service connections. Alcatel-Lucent 1665 DMX supports three different types of test access. The non-intrusive method simply taps the VT1.5/STS-1 channel as it passes through the system and routes it to an external testing device. The more intrusive mode splits the VT1.5/STS-1 from the incoming signal and sends it to an external testing device. The third form of test access involves using the internal test head, located on the
VLF only, to generate and detect Pseudo Random Bit Sequences (PRBSs) on up to 12
STS-1s or 4 STS-3(c) signals. Test access facilitates Alcatel-Lucent 1665 DMX functioning in a DCS application.
PRBS generation/detection
For detailed information regarding internal test access using PRBS, see
“PRBS generation/detection” (p. 5-40) .

Test access interworking
Alcatel-Lucent 1665 DMX supports interworking with various Test-Head vendors.
Test access rates
Alcatel-Lucent 1665 DMX supports test access sessions at the STS-1, STS3(c) and VT1.5
rates.
Integrated test access sessions
The STS1 used to transport a STS1 signal from/to the internal test generator is chosen so as to minimize the number of STS3c units of bandwidth required to transport test signals from/to the internal test signal generator/ monitor.
The test signal for an integrated STS3c test access session is composed of 3 STS1 test signals.
The interface to the internal test signal generator/monitor is 12 STS-1s. 3 contiguous
STS-1s on an STS-3c boundary (an STS-3c unit of bandwidth) are required to support an integrated STS-3c test access session.
Test signals for all VT1 tsn-initiated test access sessions are transported within the same
STS1 interface on the test signal generator/monitor. The test signal for an integrated VT1 test access session is a VT1.5 containing an unframed T1 signal based on a 220 -1 quasi-random signal sequence (QRSS).
Test access modes
Alcatel-Lucent 1665 DMX supports test access sessions in the following modes:
• MONE
• MONEF
• SPLTE
• SPLTEF
• SPLTA (for PRBS generation/detection only)
MONE mode
The MONE mode is used to monitor the E Tributary input signal of a one-way cross-connection or an idle E Tributary input signal (no cross-connection).

If the F Tributary is entered, the F Tributary must be the destination of a one-way cross-connection that has the E Tributary as the source. If the E Tributary is part of a one-way multicast cross-connection, entering the F Tributary is optional. The system automatically retrieves the other end. The E Tributary or F Tributary can not be on an
Ethernet circuit pack.

If more than one independent one-way cross-connection exists to the E Tributary, the SPLTE mode is denied. The E Tributary can also be idle (no cross-connection). The E Tributary or F Tributary cannot be on an Ethernet circuit pack.

PRBS generation/detection
Test access using PRBS generation/detection via the internal test head on the VLF Main allows the user to test network, NE, and facility performance/integrity without an external test head. VLF Mains contain an internal test head that can generate and detect errors in
Pseudo Random Bit Sequences (PRBSs). This capability is not meant to wholly eliminate the use of external equipment for tests, but can be used for expediency, less complicated tests, and where non-manual set-up is advantageous. PRBS enabled test access involves initiating test access, inserting a test signal (i.e. a PRBS) generated internal to the NE, and/or monitoring a received test signal internal to the NE. PRBS generation/detection is supported on STS1, STS3c, and VT1.5 tributaries.
Alcatel-Lucent 1665 DMX allows up to 12 test access sessions at a time and for a mix of test access sessions that specify tatrib(s) and test access sessions to the internal test head within the 12 allowed sessions. The generators and detectors are separately allocated. The internal test head hardware supports signal generation on up to 12 STS1s, and signal detection on up to 12 STS1s. Internal VT1.5 test access uses one of available STS1s and multiple internal VT test access sessions use the same STS1. Internal VT test access count as the available access sessions even though they are inside the STS-1 Internal test access is supported on STS3c signals; requests using the tatrib parameter(s) are denied. When a generator or detector is allocated to an STS3c session, it uses 3 of the 12-STS1 capacity, and that 3 generators or detectors on the STS3c boundary must be available.
Generation and detection functionality
PRBS Generation is totally independent of detection and error counting. The only similarity is that they both occur in the context of test sessions. One session may produce a signal that is detected/measures by a different session (in the same, or different
Alcatel-Lucent 1665 DMX).

While measurement/monitoring of incoming PRBS signals is occurring, the shelf collects total measurement session counts and PM-style counts, including 15-minute and day bins tied to the time-of-day clock. The bins are retrieved by the user on-demand and are freed when the test access session (not the measuring session) ends. Bins survive a shelf restart and are initialized by a power-up of the shelf.
Modes allowed for PRBS functionality
Alcatel-Lucent 1665 DMX supports PRBS enabled internal test access sessions in the following modes:
• MONE
• SPLTE
• SPLTA
Alcatel-Lucent 1665 DMX must be in MONE mode to initiate a PRBS enabled test access session. The mode must then be changed to either SPLTE or SPLTA in order to support the configurations detailed below.

Alcatel-Lucent 1665 DMX supports network test access configurations where a single test head is shared by multiple NEs, at different locations (i.e., a subnetwork). It requires that some (small) bandwidth among nodes in the subnetwork be “reserved” for testing purposes. This bandwidth is shared dynamically by the NEs, under the control of an external OS. The NE needs provides the ability to assign test access tributaries to arbitrary higher rate interfaces. Intermediate NEs see the pass-through, or add/drop test access tributaries as normal cross connections, on their way to the test head somewhere else in the subnetwork. To assist in this application, Alcatel-Lucent 1665 DMX supports the assignment of protected UPSR tributaries as test access tributaries.

Protection switching
Overview
Purpose
This section describes the types and functions of protection switching in Alcatel-Lucent
1665 DMX.
Contents
Protection switching application modes
Path protection switching (path switched rings)
Line protection switching (line switched rings)
Protection switching application modes
Overview
There are five types of protection application modes, listed below:
• BLSR (OC-48 and OC-192)
• UPSR (revertive [STSn only] and non-revertive)
• Linear 1+1
-Unidirectional 1+1 (revertive and non-revertive)
-Bidirectional 1+1 (revertive and non-revertive)
-Bidirectional optimized 1+1
• 0x1
• 0x1Sn
The UPSR application mode provides ring path protection switching on all high-speed and low-speed OC-3/12/48 interfaces and on OC-192 high-speed interfaces.
The linear 1+1 application is functionally equivalent to a 1+1 protected configuration, providing path switching on all paths within a high-speed line if that particular line fails.

0x1Sn mode
When equipped with non-VLF Main packs, Alcatel-Lucent 1665 DMX supports an unprotected 0x1Sn mode. This option is user-provisionable on a per-port basis. 0x1S1 and
0x1S2 are provisionable applications for LS OC-n port pairs. For 0x1S1, the port in slot 1 is unprotected and the companion port in slot 2 is unused. For 0x1S2, the port in slot 2 is unprotected and the companion port in slot 1 is unused.
True 0x1 mode
When equipped with VLF main packs, Alcatel-Lucent 1665 DMX supports true 0x1 unprotected circuit packs. Any function or growth slot can be equipped with any pack
(some restrictions apply) and two of the same circuit pack can also populate adjacent slots in the same group (this includes some Ethernet packs). For detailed information on circuit pack/slot equipage restrictions in 0x1 mode, see
“Very large fabric (VLF) engineering rules” (p. 6-15) .
In the case of SONET packs, all ports in a pack must be set to 0x1 application in order for a different pack to be used in the companion slot. If any pair of lines is provisioned for a protected application (1+1, UPSR, BLSR), then both packs in the group must be of the same type.
True 0x1 replaces 0x1Sn functionality when VLF Mains are used. True 0x1 supports all the capabilities 0x1Sn allow, but adds the capability for both slots of a single group to function independently. 0x1Sn is still supported when the shelf is equipped with non-VLF
Mains. True 0x1 is available on the low-speed/tributary circuit packs, and VLF Main
(M1/M2) interfaces.
When two circuit packs in the same low-speed group are operating in 0x1 mode, all provisioning, reporting and retrieval (of alarms) associated with the pack, ports and tributaries in Slot 1 are independent of the provisioning, reporting and retrieval associated with the pack, ports and tributaries in Slot 2.
When provisioned for 0x1 operation, the affect on service and severity of alarms issued against a pack in Slot 1 of a particular group are independent from the affect on service and the severity of the alarms issued against the pack in Slot 2 of that group.
When Alcatel-Lucent 1665 DMX is equipped with VLF Mains, all 1-way cross-connections supported on an unprotected port/line (including ports/lines on an unprotected pack) in one slot of an LS group can be supported independently and simultaneously on an unprotected port/line in either slot of a Function or Growth group.
1-waypr cross-connections are not allowed to be sourced from 0x1 interfaces.
True 0x1 enables hairpin cross-connections between channels on packs in different slots of the same Function or Growth group.

Ethernet interface protection
On the WAN (SONET) side of the network, Alcatel-Lucent 1665 DMX utilizes standard
IEEE 802.1D and fast 802.1w spanning tree protection for multipoint applications and/or
STS-1 UPSR protection (for point-to-point applications). See the section entitled
for more information.
Alcatel-Lucent 1665 DMX supports link aggregation on any two LNW170 LAN ports of the same rate (i.e. 100 or 1000 Mbps), operating in switched mode. The LNW170 circuit pack supports LAG operation across two LNW170 circuit packs.
LAG is also supported on the LNW910 pack. In unprotected mode, LAGs can be created from 2 FE/GE ports on the pack. In protected mode, LAGs are automatically created for ports 1–10. If required, the user can provision a LAG on port 11 (10GbE port).
Link aggregation can also provide facility protection on LNW170/LNW910 LAN ports.
For more information on link aggregation, see
“Link aggregation” (p. 5-59) .
Line protection switching
Overview
Alcatel-Lucent 1665 DMX offers 5 modes of linear protection switching: unidirectional
1+1 non-revertive line switching, bidirectional 1+1 non-revertive, unidirectional 1+1 revertive line switching, bidirectional 1+1 revertive, and bidirectional optimized 1+1 protection switching. All linear protection switching occurs automatically in response to detected faults, or in response to external commands from technicians at a local or remote
CIT or OS.
Beginning in Release 9.0, you can change 1+1 protection group from unidirectional to bidirectional in-service without deleting cross-connections.

Protection switching priorities
Alcatel-Lucent 1665 DMX uses standard protection switching priorities as follows:
• Lockout of protection
• Forced switch (FS)
• Automatic switch: signal fail (SF)
• Automatic switch: signal degrade (SD)
• Manual switch (MS)
Alcatel-Lucent 1665 DMX allows you to provision these parameters with different priorities in relation to each other. For example, SF can be set with a higher priority than
FS and vice versa.
Unidirectional and bidirectional 1+1 non-revertive and revertive line switching use switch procedures as specified by the SONET standards.
Alcatel-Lucent 1665 DMX offers bidirectional optimized 1+1 protection switching which uses switching procedures specified in ITU-T G.841, Annex B. Bidirectional optimized
1+1 is designed to enable interoperability between Alcatel-Lucent 1665 DMX and SDH equipment. It is a separate switching scheme from standard 1+1 bidirectional and does not work with standard 1+1.
Automatic line switching
Automatic line switches are initiated by signal fail and signal degrade conditions on the received OC-n signal. This signal's BER is calculated from violations in the SONET line overhead B2 parity byte. Signal fail is declared for incoming loss of signal, loss of frame, line AIS, or a BER exceeding a provisionable 10
-3 exceeding a provisionable 10
-5 to 10
-9 to 10
-5 threshold, while a BER threshold causes the signal degrade condition. A line protection switch is completed within 50 milliseconds of the onset of a hard failure such as a fiber cut.
In multispan applications (for example, hubbing), each OC-n span switches independently. For example, in hubbing applications, a switch on the central office-to-hub span will not cause switches on any of the hub-to-remote spans. Similarly, a line switch on a hub-to-remote span will not propagate to other hub-to-remote or central office-to-hub spans.

Path protection switching (path switched rings)
Overview
Alcatel-Lucent 1665 DMX supports path switched ring applications using the path protection switching schemes described in Telcordia
®
GR-1400. This scheme offers
60-millisecond restoration times and simple network administration for access applications. The ring facility consists of two fibers, with service and protection rotating in opposite directions. Each input is bridged and transmitted in both directions around the ring. The receiving end terminal monitors the quality of both signals and selects the best signal to drop.
UPSR configurations
Alcatel-Lucent 1665 DMX supports the following OC-3/OC-12/OC-48/OC-192 path switched ring configurations:
• OC-3: VT1.5/STS-1/STS-3c
• OC-12: VT1.5/STS-1/STS-3c/STS-12c
• OC-48: VT1.5/STS-1/STS-3c/STS-12c/STS-48c
• OC-192: VT1.5/STS-1/STS-3c/STS-12c/STS-48c/STS-192c
Path protection is user-provisionable on a per-cross-connection basis when the port is set to UPSR. A manual path protection switching command allows switching to the other path for ease of ring maintenance. Beginning in Release 10, a UPSR path switching can be provisioned as nonrevertive (default) or revertive on a per STS-n path-protected cross-connection basis. The designation of the working path, also referred to as the preferred path, is provisionable on a per-path-selector basis. STS-n path switching is triggered by path defects Path AIS (AIS-P), UNEQ-P, LOP-P, F BER (excessive BER) and SD. The system also supports VT path protection switching based on VT AIS
(AIS-V), LOP-V, UNEQ-V, and VT SD. Line level defects (LOS, LOF, AIS) indirectly contribute to path switching because these errors generate downstream path AIS (AIS-P).
Mixed protection modes
By supporting protection mode provisioning on a per port basis, Alcatel-Lucent 1665
DMX provides for the mixing of protection modes across the ports of a multi-port pack.
Ethernet interface protection
On the WAN (SONET) side of the network, Alcatel-Lucent 1665 DMX utilizes standard
IEEE 802.1D and fast 802.1w spanning tree protection for multipoint applications and/or
STS-1 UPSR protection (for point-to-point applications).

Locked cross-connections
In the "locked" mode, Alcatel-Lucent 1665 DMX does not select the best signal from both rotations of a UPSR. Instead, traffic is added and dropped (locked) from one rotation of the ring only (provisionable). The main advantage of locked VT cross-connections is the lack of UPSR switching which results in the ability to reuse time slots around a
UPSR.
Locked cross-connections are only used in systems that are not equipped with VLF Mains because VLF mains allow unprotected (linear) UPSR cross-connections which allow users to independently provision cross-connections on UPSR tributaries. In systems with non-VLF Mains, once a locked cross-connection is established from a UPSR tributary, the companion tributary cannot be cross-connected.
Alcatel-Lucent 1665 DMX has the ability to mix locked, unlocked, and pass-through
VT1.5s within the same STS-1, and to allow both rotations of a ring to be used simultaneously.
Linear/Unprotected UPSR
Alcatel-Lucent 1665 DMX provides an unprotected cross-connection mode, referred to as
Linear/Unprotected UPSR, on OC-3/12/48 low-speed ports and OC-3/12/48/192 high-speed UPSRs. Alcatel-Lucent 1665 DMX allows both rotations of a ring to be used simultaneously. Simultaneous 1WAY cross-connections can be sourced from the 2 associated ring channels in a UPSR application. Simultaneous 1WAY cross-connection can be sourced from a ring channel. Support is also provided for 1WAY or 1WAYPR destined to the associated ring channel.
Line protection switching (line switched rings)
Overview
A 2-fiber bidirectional line-switched ring (BLSR) is a self-healing ring configuration in which switching is bidirectional between each pair of adjacent nodes and is protected by redundant bandwidth on the bidirectional lines that interconnect the nodes in the ring.
Because switching is bidirectional between nodes, traffic can be added at one node and dropped at the next without traveling around the entire ring. This leaves the spans between other nodes available for additional traffic. Therefore, with distributed traffic patterns, a BLSR can carry more traffic than the same facilities could carry if configured for a unidirectional line-switched ring.
Alcatel-Lucent 1665 DMX supports 15 simultaneous BLSR protection groups in a single shelf. The 15 protection groups can be provisioned on any available OC-48 and OC-192 port pairs within the high-speed and low-speed groups.

Self-healing rings
Alcatel-Lucent 1665 DMX 2-fiber BLSRs are self-healing in that transport is automatically restored after node or fiber failures. Each OC-192 line carries 96 STS-1 equivalent time slots of working capacity plus 96 STS-1 equivalent time slots of protection capacity. Each OC-48 line carries 24 STS-1 equivalent time slots of working capacity plus 24 STS-1 equivalent of protection capacity. In the event of a fiber or node failure, service is restored by switching traffic from the working capacity of the failed line to the protection capacity in the opposite direction around the ring. In the event of a node failure, traffic added and dropped from the failed node is not protected by line switching.
Protection switching
When a line failure triggers a protection switch, the nodes adjacent to the failure switch traffic on to protection capacity. Traffic heading toward the failure is looped back on to the protection capacity traveling away from the failure to reach its destination by traveling the opposite way around the ring. Service is reestablished on the protection capacity in 50 milliseconds after detection of the failure (for catastrophic failures in rings without existing protection switches or extra traffic).
Spanning tree
Overview
This section provides information on the spanning tree protocol and spanning tree groups.
Alcatel-Lucent 1665 DMX now supports a faster spanning tree algorithm documented in
IEEE 802.1w.
Important! Alcatel-Lucent 1665 DMX has been designed with multi-vendor interoperobility in mind. As many vendor's equipment (including legacy equipment) may not be able to use IEEE802.1w, Alcatel-Lucent 1665 DMX can automatically fall back on IEEE802.1d in the event that other NEs in the network are running standard spanning tree protocol. However, Alcatel-Lucent 1665 DMX employs IEEE 802.1w
as a default spanning tree protocol.
Function of spanning tree
Ethernet requires a network with a tree structure in order to work effectively. Ethernet bridges and switches build tables that define the paths to specific devices. A MAC bridge, for example, will have a filtering database that defines where to send any packets addressed to a specific MAC within the network. The tables are built based on input from devices within the network.

Spanning tree
....................................................................................................................................................................................................................................
If there is a loop in the network, that is, if there is more than one way to get to a destination device, two problems can result:
• Frames may be duplicated in the network. That is, the same frame may be sent to a node via two different paths.
• The address information is changed as packets from that device are received across different paths. In a meshed network, the re-configuration of the filtering database can begin to use up all the network resources, so that little bandwidth is left for data traffic.
The spanning tree accomplishes two important functions:
• It removes loops from the bridged network
• It allows re-configuration if a link fails.
How it works
The spanning tree works as follows:
1. Initially, every node in the group thinks it is the root node.
2. As information about the network becomes clear, one node is designated the root node. It is from this node that the distance to any point in the network may be measured.
3. Configuration BPDUs are sent from each node to determine the most economical route from each node to the root node.
4. Some ports are blocked so that there are no loops in the network and so that the network provides the most efficient paths from the root to the nodes. This effectively creates a tree structure for the network.
5. If an active link fails, the network is re configured so that previously blocked links can be used for traffic.
The following figure illustrates the spanning tree:

The configuration provides the shortest (most efficient) path from each node to the root.
The configuration also provides only one path from the root node to any other node.
Re-configuration
If one of the active links were broken, the network would re-configure to allow traffic to get to the nodes. For example, if the link between 3 and 4 were broken, the link between 5 and 4 would be enabled. When the failure/break is repaired, the network will revert to the original configuration.
Spanning tree on LAN ports
Alcatel-Lucent 1665 DMX supports spanning tree on the LAN (customer facing) ports.
STP on LAN ports ensures that single LAN interconnects are protected. Because redundant LAN interconnects create loops, STP manages the loops. STP is supported on the LAN ports of the LNW170 only.
Both LAN ports and VCGs can belong to STP groups. A LAN port can belong to only one STP group at a time. The BDPU VLAN ID is provisionable. VLAN IDs are provisionable on a per-port basis.

Rapid spanning tree maintenance enhancements
Alcatel-Lucent 1665 DMX supports the following rapid spanning tree maintenance enhancements:
• Additional performance monitoring counters for VCG and LAN ports or Link
Aggregation Groups (LAGs) to record spanning tree modification status
• Spanning tree group Automatic Lock parameter to disable a port which is unstable or rapidly reconfiguring. When the Automatic Lock parameter is enabled and any port in the Spanning Tree Group experiences a threshold-crossing alert (TCA) on the spanning tree state counter, the port is moved to the disabled-failure state preventing traffic flow until released.

Link aggregation
Overview
Alcatel-Lucent 1665 DMX supports link aggregation on any two LNW170 LAN ports of the same rate (that is, 100 or 1000 Mbps), operating in switched mode. The LNW170 supports LAG operation across LNW170 packs, and equipment protected link aggregation.
LAG is also supported on the LNW910 pack. In unprotected mode, LAGs can be created from 2 FE/GE ports on the pack. In protected mode, LAGs are automatically created for ports 1–10. If required, the user can provision a LAG on port 11 (10GbE port).
Hitless bandwidth increase/decrease
Ordinarily, multiple Ethernet links between two bridges form loops (unless a spanning tree blocks all but one) so they can't be used to increase bandwidth. Link Aggregation causes defined groups of links to be treated as a single logical link, making multiple LAN ports appear as one. In this way, Bandwidth may be increased without requiring an upgrade to a higher rate link.
Facility protection
Link aggregation can also remove failed links automatically, thereby providing a means of facility protection. When a link fails, traffic is shifted to the remaining links in that
Link Aggregation Group (LAG). More links than are needed can be added to the group and each is active until it fails (similar to utilizing LCAS protection for SONET tributaries). When two links are on different packs they can provide both, facility and equipment protection.
Active/Standby LAG
In Active/Standby LAG, one link of the LAG is designated as the protection link and the other is the working link. Only the working link carries MAC client traffic when none of the links fails. When the working link fails, the traffic switches to the protection link. The protection switching is bidirectional and revertive.
Equipment protection
The LNW170 and LNW910 circuit packs can be provisioned for equipment protection, in which link aggregation plays a role.
LNW170
The LNW170 supports equipment protection of function group pairs (e.g. D1, D2) using an interpack interface. Only ports 1, 2, 5 and 6 are usable. Ports 3, 4, 7 and 8 cannot be used. Signals of all usable LAN ports are fed to both LNW170 cards via the interpack interface, so that the same-numbered port of each pack belongs to a preset Link

Aggregation Group. When a pair of LNW170s is used in equipment protection mode, both LNW170s are provisioned identically, except for certain physical layer parameters that remain independent. They send and receive the same signals across the backplane toward the Mains. The Mains select which of the pair is the ActiveWAN.
Link aggregation control protocol
Link Aggregation is specified in IEEE 802.3 clause 43, formerly specified in 802.3ad. An pack can be configured to either use this standard protocol to control link aggregation
(which negotiates with the equipment at the other end of the link) or to simply force aggregation without a control protocol. Both ends should be provisioned to use the same protocol
General link aggregation rules
Link aggregation behaves along the following basic guidelines:
• Available for LAN ports on the LNW170 in switched mode only
• Maximum of 4 LAGs per pack, 2 ports per LAG, and 8 LAGs per function unit or growth group. There are 8 ports on each LNW170 pack.
• The two ports in a LAG must be on the same pack, and be functioning at the same rate (i.e. 100 or 1000 Mbps).
• All links in a LAG are in-service until they fail. Standby links, providing 1x1
SONET-style protection, are a future feature.
• When a LAG is created, the attributes (VLAN, virtual switch, and other L2 provisioning) of the first port used to establish the LAG are transferred to the LAG.
When the second port is added, it then inherits the L2, VLAN and Virtual Switch (VS) characteristics of the LAG for the time it remains a member. It can not be part of a VS or have any VLAN provisioning when added.
– Both member ports can also be added simultaneously and Alcatel-Lucent 1665
DMX recognizes a parameter that distinguishes the "Lead Port". The LAG (and by association, the other port in the LAG) inherits the L2, VLAN, and VS attributes of the Lead Port.
• When a port is removed from a particular LAG, it is no longer a member of a VS.
• A port must have L2 and VS provisioning in order for a port to be used as the Lead port or to establish a LAG (VLAN provisioning not required). This information is then transferred to the LAG once it's created.

• The last port/member of a LAG cannot be removed from the LAG; the LAG itself must be deleted. The last port/member of a LAG inherits the LAG's L2, VLAN, and
VS attributes.
– If the last member in the LAG was the first member added originally, and if there were no subsequent changes to L2 and VLAN attributes, the port will effectively revert to its original state when the LAG is deleted.
– If the last member/port in the LAG was not the first added initially it will inherit the characteristics of the LAG rather than reverting to its original state.
Link aggregation example
The figure below depicts link aggregation on two LNW170 LAN ports functioning at
100Mbps. The top portion of the figure shows two ports receiving separate 100 Mbps inbound flows. The bottom portion depicts the same two flows being equally split across the two outbound ports in the LAG. In this example, no failure has occurred and both ports comprising the LAG are in-service.
Traffic entering incoming ports is aggregated into a LAG. While both ports are in-service, outgoing traffic is split between working ports.
Figure 5-14 Link aggregation at 100 Mbps (all ports in-service)
The instance pictured above represents the ideal case, in which there are at least 2 flows, each a maximum of 100Mbps. In this case they can be equally split over the two ports comprising the LAG. The ability to split the two flows across multiple ports also depends on the distribution of MAC/IP addresses.
Link aggregation employs an algorithm that assigns traffic to member ports to prevent misreading. A given flow can be assigned to only one port and cannot be split across multiple ports in the same LAG. To increase flexibility, Alcatel-Lucent 1665 DMX allows a flow to be defined by either a MAC source and destination address pair or an IP source

and address pair. The algorithm uses the XOR of the least significant bits of the address pairs to assign a port/link. Therefore, the actual load balancing achieved depends on the distribution of MAC/IP addresses.
Link aggregation transparency
Link aggregation allows multiple physical links between Ethernet switches to be treated as a single link. This provides for more bandwidth between the switches than can be transmitted over a single Ethernet port and it can provide protection from a cable,
Ethernet port, or Ethernet circuit pack failure.
The Alcatel-Lucent 1665 DMX supports link aggregation transparency, as shown in the following figure. This allows the attached equipment to use link aggregation without participation by the Alcatel-Lucent 1665 DMX provisioning.

The figure shows two Ethernet devices running link aggregation interconnected via
Ethernet circuit packs and a SONET Network. The Alcatel-Lucent 1665 DMX shelves and the SONET network are invisible to the two Ethernet devices. The Ethernet traffic is transparently transferred between the external devices. Link aggregation is typically implemented using two dedicated unprotected point-to-point links (Ethernet Private Line
Service) for each pair of external ports.
Link aggregation transparency requires a default VLAN ID tag or port tag in 802.1Q and
Transparent Tagging mode. If a default VLAN or port tag is not specified at the port, the link aggregation messages are dropped.

Equipment protection
True 0x1 mode
The VLF Main circuit packs (LNW59, LNW82, and LNW504), allow true 0x1 unprotected operation for circuit packs. That means that tributary circuit packs can function unprotected and any slot can be equipped with any pack (some restrictions apply). Two unprotected circuit packs of the same type can also populate adjacent slots in the same group (this includes some Ethernet packs). For detailed information on circuit pack/slot equipage restrictions in 0x1 mode, see
“Very large fabric (VLF) engineering rules” (p. 6-15) .
For OC-n ports, the 0x1 application is provisionable on a per-port basis. This allows packs with multiple ports to function in mixed modes with some ports running in a protected mode (UPSR, BLSR, 1+1), while others can be 0x1 unprotected.
In order for an OC-n pack to be unprotected, allowing 2 packs of the same kind to populate adjacent slots as stated above, all ports on the pack must be provisioned for 0x1.
When unprotected, all provisioning, reporting and retrieval (of alarms) associated with the pack, ports and tributaries in Slot 1 are independent of the provisioning, reporting and retrieval associated with the pack, ports and tributaries in Slot 2.
When provisioned for 0x1 operation, the affect on service and severity of alarms issued against a pack in Slot 1 of a particular group are independent from the affect on service and the severity of the alarms issued against the pack in Slot 2 of that group.
Protection switching priorities
The following protection switching priorities on equipment are user-controllable through
TL1 commands:
• inhibit switch (low-speed interfaces only)
• forced switch (low-speed interfaces only)
• signal fail (low and high-speed interfaces)
• manual switch (low and high-speed interfaces)
If protection is not desired, interfaces can be provisioned for no protection by not equipping the adjacent Function Unit slot.

Performance monitoring terms
Overview
Alcatel-Lucent 1665 DMX uses performance monitoring (PM) to support proactive maintenance of the network and tariffed service performance verification. Proactive maintenance refers to the process of detecting degrading conditions not severe enough to initiate protection switching or alarming but indicative of an impending hard or soft failure. Hard and soft failures result in reactive maintenance. PM conditions are reported on both SONET and electrical interfaces.
Proactive maintenance
Proactive maintenance consists of monitoring performance parameters associated with the
SONET sections, lines and paths within the SONET network, as well as incoming and outgoing bytes and frames on electrical (DS1/3) ports. The
“Standard SONET PM MIB module” (p. 5-112)
section, lists the SONET performance parameters monitored by
Alcatel-Lucent 1665 DMX. Thresholds are set for these parameters to identity degraded performance. When a performance-monitoring threshold is crossed, it is reported to the message-based operations system where all threshold crossings associated with a particular path can be correlated, and the likely source of the degradation can be identified. Electrical performance monitoring parameters are listed later in this section.
The figure below shows DS1/DS3 line and path and DS3 path performance monitoring.
Alcatel-Lucent 1665 DMX monitors DS3 line and path parameters from the DSX-3 and
DS3 path parameters from the optical path.

Section parameter
No Far-End PM parameters are defined for the Section layer. The system, as it receives
SONET signals, terminates the SONET Section and Line layers and therefore is involved with Section layer PM. Section layer PM applies to optical and electrical SONET interfaces. It also applies to service and protection sections of optical sections.

Line parameter
A line is a physical transport vehicle that provides the means of moving digital information between two points in a network. The line is characterized by a metallic transmission medium and its specific coding type. A line is bounded by its two end points, known as line terminations. A line termination is the point where the electrical, bipolar line signal is generated and transmitted, or received and decoded.
Path parameter
A path is a framed digital stream between two points in a network and represents digital signal transport at a specified rate, independent of the equipment and media providing the physical means of transporting the signal. A path is defined by its two end points, called path terminations, where its frame structure is generated and decoded. A path may be carried wholly within one transport segment (line), or it may span a sequential arrangement of two or more transport segments.
Optical transmission section (OTS) parameter
The OTS layer is the lowest layer of the optical layer network (OLN)/optical transport network (OTN) that provides physical transport of the optical multiplex section (OMS) layer signal via the optical terminal multiplexer (OTM). The OTS layer is terminated on the OTS terminating equipment. The OTS layer represents the server layer for the OMS layer. The OTS layer is comparable in function to the SONET section layer.
Optical channel layer (OCH) parameter
The OCH layer is the top layer of the OLN that provides transport of client signals (e.g.,
SONET, GbE, OTUk). The OCH layer is terminated on an OCH terminating equipment.
The OCH is the information structure used to support the OCH trail. The OCH layer represents the client layer for the OMS layer. The OCH layer is comparable in function to the SONET path layer. The OCH is an information structure consisting of the information payload with a certain bandwidth and non-associated overhead for management of the optical channel.
The LNW785 has 8 OCH ports, supporting ITU-T DWDM channels 52 through 59
(195.20–195.90 THz).

DS1 performance monitoring
Tariffed service verification consists of monitoring performance parameters that can be associated with the customer's end-to-end service. Alcatel-Lucent 1665 DMX provides this capability for DS1 services with the DS1 performance monitoring feature. Based on
ANSI T1.403 extended superframe format (ESF), this capability retrieves performance messages written into the ESF data link by the customer's terminal equipment. From these messages, Alcatel-Lucent 1665 DMX can determine and report the end-to-end error performance of the entire DS1 link as seen by the customer. The parameters, listed in
Table 5-9, “DS1 performance parameters” (p. 5-72) , are set and reported to indicate
degraded performance. The counts are retrieved by the message-based operations system to determine if the service is operating within tariffed limits.
Application of the DS1 performance monitoring feature for tariffed service verification is shown in the figure below. This shows an ANSI T1.403 ESF format DS1 service carried between points A and Z, using an OC-48/OC-192 system and terminated at the customer's premises with channel service units (CSUs). At the "A" end, the received error performance, (Z–A) is detected and written by the customer CSU onto the outgoing
(A–Z) ESF data link as a performance report message (PRM). The DS1 PM circuit pack interfacing the A end reads the incoming DS1 signal's PRM (received from the customer's premises) and reports the Z–A performance. Likewise, the OC-48/OC-192 system interfacing the Z end reports the A–Z performance by reading the PRM from the customer's "Z" CSU. By reviewing data from each OC-48/OC-192 system, the service provider can determine the complete end-to-end performance (A–Z) and Z–A) of the customer's service.

DS1PM circuit pack
Additionally, each PM enabled DS1 circuit pack measures the near-end performance of the incoming DS1, allowing the service provider to determine if a good DS1 signal was received from the customer before transporting it through the network. This information can aid in isolating any reported performance problems. The circuit pack can also provide this same near-end information for super frame (SF) formatted (sometimes known as "D4 framing") DS1 services, but complete end-to-end performance verification is limited due to the lack of the PRM in the SF format.

DS3 performance monitoring
Alcatel-Lucent 1665 DMX provides DS3 performance monitoring with three DS3 path
PM options: P-bit (parity bit), adjusted F&M bit (frame and multiframe bit), and C-bit.
P-Bit
When FMT is set to P-bit, P-bit errors are used as the basis for determining code violation counts. When provisioned for P-bit, the system calculates and provides counts of DS3
P-bit coding violations (CV), errored seconds (ES), and unavailable seconds (UAS) incoming from the fiber. Quarter-hour and day registers are provided with provisionable threshold crossing alerts (TCAs) on a per-shelf basis. Severely errored frame seconds
(SEFS) are also monitored.
Because P-bits can be corrected at nodes provisioned for VMR along a DS3 path, the DS3
P-bit PM data may not provide a complete report of the end-to-end DS3 path errors.

Adjusted F&M bit
When FMT is set to FM-bit, F&M bits are used as the basis for determining code violation counts. Adjusted F&M bit performance monitoring provides an alternative method for determining and accumulating DS3 path performance data based on an error estimation technique using errors on the F&M framing bits to approximate the actual error counts in the DS3 path payload. F&M bits are not corrected at nodes provisioned for
VMR along a DS3 path. When provisioned for adjusted F&M bit, the system calculates and provides estimated counts of DS3 adjusted F&M bit coding violations (CV), errored seconds (ES), severely errored seconds (SES), and unavailable seconds (UAS) incoming from the fiber.
Quarter-hour and current day registers are provided with provisionable threshold crossing alerts (TCAs) on a per-shelf basis. Severely errored frame/AIS seconds (SAS-P) are also monitored.
C-Bit
When FMT is set to cbit, C-bit errors are used as the basis for determining code violation counts.
The system provides counts of DS3 C-Bit parity coding violations (CV-P), errored seconds (ES-P), severely errored seconds (SES-P), and unavailable seconds (UAS-P) incoming from the DSX-3 and the fiber. The type of performance monitoring is provisioned per DS3 service by a CIT command.
For C-bit PM, the DS3 service can be provisioned in violation monitor (VM) or violation monitor and removal (VMR) modes. In VM mode, the C-bit errors are not corrected as in the P-bit option.
Quarter-hour and day registers are provided with provisionable threshold crossing alerts
(TCAs). The TCAs are provisionable on a per-shelf basis. Severely errored frame seconds
(SEFS) counts are also provided.
Performance monitoring reports
Summary reports and status reports are available to perform performance monitoring.
TCA summary report
Alcatel-Lucent 1665 DMX provides a report that lists the number of SONET, DS1, and
DS3 performance-monitoring parameters that have crossed their thresholds. This report provides a snapshot of the system performance level. If there is signal degradation, it is quickly pinpointed so that corrective action may be taken before customers are affected, thus supporting proactive maintenance. Threshold-crossing alerts (TCAs) are reported on the Ethernet parameters listed in the table above.

Performance status reports
These reports provide detailed information on the current and previous 8 hours in quarter-hour (15-minute) increments, as well as the current and previous day's performance. Threshold crossing alerts are clearly identified and the time the performance registers were last initialized is also shown. Any registers that may have been affected by this initialization are marked. There are separate reports for section, line, and path parameters, as well as Ethernet parameters.
Ethernet performance monitoring
Alcatel-Lucent 1665 DMX provides PM capabilities for the 10/100/1000T, 1G SX, and
1G LX, and 1G ZX Ethernet interfaces. PM data is collected at each LAN and WAN interface in the network for both incoming and outgoing directions. The WAN interface provides a connection to a SONET Virtual Concatenation Group (VCG).
For details regarding Ethernet PM and SNMP capabilities, see

DS1 performance monitoring parameters
Overview
This section describes the performance monitoring parameters relevant to DS1 signals incoming from the fiber or DSX-1.
DS1 ESF format
Tariffed service verification consists of monitoring performance parameters that can be associated with the customer's end-to-end service. Alcatel-Lucent 1665 DMX provides this capability for DS1 services when equipped with 28DS1 circuit packs with the DS1 performance monitoring feature (28DS1PM [LNW7]) and the high density
LNW8/LNW801 56DS1/E1 circuit pack. Based on ANSI T1.403 extended superframe format (ESF), this capability retrieves performance messages written into the ESF data link by the customer's terminal equipment. From these messages, Alcatel-Lucent 1665
DMX can determine and report the end-to-end error performance of the entire DS1 link
as seen by the customer. The counts are retrieved by the message-based operations system to determine if the service is operating within tariffed limits.

DS1 SF format
Each 28DS1PM and 56DS1/E1 circuit packs measure the near-end performance of the incoming DS1 signals, allowing the service provider to determine if a good DS1 signal was received from the customer before transporting it through the network. This information can then aid in isolating any reported performance problems. The 28DS1PM and 56DS1/E1 circuit packs can also provide this same near-end information for super frame (SF) formatted (sometimes known as "D4 framing") DS1 services, but complete end-to-end performance verification is limited due to the lack of the PRM in the SF format.

DS1 line parameters
Alcatel-Lucent 1665 DMX monitors the near end DS1 line parameter on incoming (from the DSX-1 cross-connect) DS1 signals. The parameter is measured at the input of the DS1 circuit pack on the DS1 line side (also referred to as facility, customer terminal, or DSX side).

Coding violations (CV-L)
The Near-End Line Coding Violation (CVL) parameter for each SONET Line is monitored. The Near-End CVL parameter increments once for every occurrence of a BIP error detected at the Line layer (i.e. using the B2 byte in the incoming SONET signal). Up to 8*N BIP errors can be detected per STS-N frame.
Errored seconds (ES-L)
The near end ES-L parameter increments once for each second during which
Alcatel-Lucent 1665 DMX detects either one or more bipolar violations (BPVs) or excessive zeros (EXZ), or one or more LOS defects.
Severely errored seconds (SES-L)
The Near-End Line Severely Errored Seconds (SESL) parameter for each SONET Line is monitored. The Near-End SESL parameter increments once for every second that contains at least K BIP errors detected at the Line layer (at any point during the second), or an
AIS-L defect was present. The value of K is hard-coded, see table 7 for a list of the values

TMUX circuit pack on the DS1 line side (also referred to as facility, customer terminal, or
DSX side).
Coding violations (CV-P)
For the SF format, the CV-P parameter increments once for each frame synchronization bit error (FE) detected at the path level. For the ESF format, the CV-P parameter increments once for each cyclic redundancy check error (CRC) detected at the path level.
Errored seconds (ES-P)
For the SF format, he ES-P parameter increments once for each second during which
Alcatel-Lucent 1665 DMX detects FE errors, CS events, SEF defects, or AIS defects. For the ESF format, he ES-P parameter increments once for each second during which
Alcatel-Lucent 1665 DMX detects CRC errors, CS events, SEF defects, or AIS defects.
Severely errored seconds (SES-P)
For the SF format, the SES-P parameter increments once for each second during which
Alcatel-Lucent 1665 DMX detects 8 or more FE events (if Ft and Fs bits are measured) or
4 or more FE events (if only Ft bits are monitored), or SEF defects, or AIS defects.

Far end DS1 path parameters
Alcatel-Lucent 1665 DMX monitors the following far end DS1 path parameters at the local network element. If the far end network element detects an incoming error, the far end network element communicates the error back to the local near end network element using Performance Report Message (PRM) frames or a Remote Alarm Indication (RAI) signal.
The far end parameters are measured at the input of the local DS1 or TMUX circuit pack on the DS1 line side (also referred to as facility, customer terminal, or DSX side).
Important! The format must be set to ESF to monitor the far end parameters
(CV-PFE, ES-PFE, SES-PFE, and UAS-PFE).

DS3 performance monitoring parameters
Overview
This section describes the performance monitoring parameters that are monitored on DS3 signals incoming from the high speed fiber and from the local DSX-3 cross-connect.
In order to generate DS3 PM reports, the port Primary State must be IS (in service).
(When the PST parameter is provisioned as AUTO and a valid DS3 signal is detected, the
PST parameter automatically transitions to the IS state.) The VM mode should be off because the P-bits can be corrected at nodes where the VM Mode is provisioned on, and the DS3 P-bit PM data may not provide a complete report of the end-to-end DS3 path errors.
Monitored parameters
The following table lists the DS3 line and path performance parameters that

Near end DS3 path parameters
Alcatel-Lucent 1665 DMX monitors the following ingress and egress near end DS3 path parameters at the local network element. Ingress refers to parameters that are measured on incoming DS3 signals at the input of the local DS3 or TMUX circuit pack on the DS3 line side (also referred to as facility, customer terminal, or DSX side). Egress refers to parameters that are measured on incoming DS3 signals at the input of the local DS3 port unit on the SONET side (also referred to as fiber side).
Coding violations (CV-P)
The near end CV-P parameter increments once for each parity error detected at the path level. The CV-P parameter applies to all performance monitoring signal formats.
In the P-bit parity signal format, P-bit errors corresponding to the same DS3 M-frame also increment the CV-P parameter.
For CP-bit parity signal format, the three C-bits in subframe 3 of a C-bit formatted DS3 frame carry the DS3 path-parity information. At the DS3 transmitter, the CP bits in the
DS3 C-bit frame are set equal to the two P-bits in frame "n". These CP bits are then inserted into frame "n+1". Since the CP bits are not modified in any way while passing through the network, the DS3 high-speed receiver can determine if errors occurred in the

DS3 path. The DS3 receiver computes the parity of frame "n" and compares that parity with the value received in the CP bits in frame "n+1". If the values do not match, DS3 path parity violations are counted.
Errored seconds (ES-P)
The near end ES-P parameter increments once for each second during which
Alcatel-Lucent 1665 DMX detects either one or more parity errors, one or more SEF defects, or one or more AIS defects. The ES-P parameter applies to all performance monitoring signal formats.
Severely errored seconds (SES-P)
The near end SES-P parameter increments once for each second during which
Alcatel-Lucent 1665 DMX detects either one or more AIS or SEF defects, 2444 or more
BPVs at a minimum BER of 7.5 X 10

Unavailable seconds (UAS-P)
A near end UAS-P is a second during which the path is unavailable. A path is considered unavailable from the beginning of 10 consecutive severely errored seconds until the beginning of 10 consecutive seconds, none of which are severely errored. The UAS-P parameter applies to the P-bit parity and FM-bit parity performance monitoring signal formats.
Severely errored frame/alarm indication signal seconds (SAS-P)
The SAS-P parameter increments once for each second during which Alcatel-Lucent 1665
DMX detects either one or more severely errored frame defects, or one or more AIS defects. The SAS-P parameter applies to all performance monitoring signal formats.

Far end DS3 path parameters
Alcatel-Lucent 1665 DMX monitors the following ingress and egress far end DS3 path parameters at the local network element. If the far end network element detects an incoming error, the far end network element communicates the error back to the local near end network element using far end block error (FEBE) bits in the DS3 path overhead. (This allows the local near end Alcatel-Lucent 1665 DMX to perform the PM accumulation, storage, threshold, and reporting functions for both the near end and far end.)

DSX side). Egress refers to far end parameters that are measured at the input of the local
DS3 port unit on the SONET side (also referred to as fiber side).
Important! The DS3 signal format must be provisioned for C-Bit and the performance monitoring signal format must be provisioned for CP-Bit Parity to monitor the far-end parameters.
Coding violations Far End (CV-PFE)
The CV-PFE parameter increments as reported by the FEBE indication in the line overhead. At the far end if an incoming DS3 path error (for example, C-bit, F-bit, or
M-bit error) is detected, an error indication is communicated back to the near end equipment by using the far end block error (FEBE) bits.
The FEBE message sent back from the far end is set to "111" if no path errors are detected. If a path error is detected, the FEBE message is set to "not 111." The FEBE monitor parameter (CV-PFE) increments once for each occurrence of a received "not all ones" pattern in the received FEBE message.
Errored seconds Far End (ES-PFE)
The ES-PFE parameter increments once for each second containing one or more
M-frames with the three FEBE bits not all set to ONE or one or more far-end SEF or one or more far-end AIS defects.
Severely errored seconds Far End (SES-PFE)
The SES-PFE parameter increments once for each second where 2444 or more FEBE errors at a minimum BER of 7.5 X 10

1 X 10
-6 are detected as reported by the FEBE indication of the path overhead or one or more far-end SEF or one or more far-end AIS defects are detected.
Unavailable seconds Far End (UAS-PFE)
The UAS-PFE parameter is a count of 1 second intervals for which the DS3 path is unavailable at the onset of 10 contiguous SES-PFEs. The 10 SES-PFEs are included in the unavailable time. Once unavailable, the UAS-PFE continues to increment once for each second until ten consecutive seconds without SES-PFE are detected. The 10 seconds without SES-PFEs are excluded from the unavailable time.
Severely errored frame/alarm indication signal seconds Far End (SAS-PFE)
The SAS-PFE parameter increments once for each second where one or more far end severely errored frame defects, or one or more far end AIS defects are detected.

....................................................................................................................................................................................................................................
If the A-Bit equals 1 in four or more double frames, then there is an RDI defect.
FEBE is based on the E-bit (ITU-T G.704).
Unavailable seconds (UAS-P)
The Near-End E1 Path UAS Seconds (UASP) parameter for each E1 path is monitored.
The UAS parameter is a count of 1 second intervals for which the E1 path is unavailable at the onset of 10 contiguous SESs. The 10 SESs are included in the unavailable time.
Once unavailable, the UAS continues to increment once for each second until ten consecutive seconds without SES are detected. The 10 seconds without SESs are excluded from the unavailable time. The UAS parameter applies to both FAS frame and
CRC-4 MultiFrame formats.
The Far-End E1 Path UAS Seconds (UASP) parameter for each E1 path is monitored.
The Far-End UASP parameter is a count of 1 second intervals for which the E1 path is unavailable at the onset of 10 contiguous SESs. The 10 SESs are included in the unavailable time. Once unavailable, the Far-End UASP continues to increment once for each second until ten consecutive seconds without SES are detected. The 10 seconds without SESs are excluded from the unavailable time. The Far-End UASP parameter applies to both FAS frame and CRC-4 MultiFrame formats.

Errored seconds (ES-P)
The Near-End STS Path Errored Seconds (ESP) parameter for each SONET path is monitored. The ESP parameter increments once for each second where one or more STS
Path layer BIP errors are detected or an AIS-P, LOP-P, or UNEQ-P defect is detected.
The Far-End VT Path Errored Seconds (ESP) parameter for each SONET path is monitored. The VT Far-End ESP parameter increments once for each second where one or more Far-End VT Path layer BIP errors were reported by the far-end VT-PTE (using the REI-V indication), a one-bit RDI-V defect was present, or an ERDI-V (if supported) defect is detected.
Alcatel-Lucent 1665 DMX detects 1-bit RDI, but treats it as though it is the high order bit of a 3-bit ERDI in that it includes UNEQ.
Severely errored seconds (SES-P)
The Near-End STS Path Severely Errored Seconds (SESP) parameter for each SONET path is monitored. The SESP parameter increments once for each second where K or more STS Path layer BIP errors are detected or an AIS-P, LOP-P, or UNEQ-P defect is detected. The integer value for K is set by standards and is selectable (values are shown in
Table 8). Alcatel-Lucent 1665 DMX detects 1-bit RDI, but treats it as though it is the high order bit of a 3-bit ERDI in that it includes UNEQ.
The Far-End VT Path Severely Errored Seconds (SESP) parameter for each SONET VT path is monitored. The VT Far-End SESP parameter increments once for each second where K or more BIP errors are reported by the far-end VT-PTE (using the REI-V indication), or a one bit RDI-V defect was present or (if ERDI-V is supported), an
ERDI-V defect is detected. The integer value for K is set by standards (values are shown in Table 10).
Alcatel-Lucent 1665 DMX detects 1-bit RDI, but treats it as though it is the high order bit of a 3-bit ERDI in that it includes UNEQ.
Unavailable seconds (UAS-P)
The Near-End STS Path Unavailable Seconds (UASP) parameter for each SONET path is monitored. The UASP parameter increments once for each second where SESP is detected after ten consecutive seconds with SESP detected. UASP continues to increment once for each second until ten consecutive seconds without SESP are detected.
The Far-End VT Path Unavailable Seconds (UASP) parameter for each SONET path is monitored. The VT Far-End UASP parameter increments once for each second where VT
Far-End SESP is detected after ten consecutive seconds with VT Far-End SESP detected.
VT Far-End UASP continues to increment once for each second until ten consecutive seconds without VT Far-End SESP are detected.

VC-12 path parameters
Background block errors (BBE-P)
The Near-End E1 Background Block Errors (BBE-P) parameter for each E1 Path is monitored. The number of Near-End BBE-Ps in a one second period is equal to the
Near-End EBC if the second is not a Near-End SES. Otherwise, the BBE-P is set to zero for that second.
The Far-End Background Block Errors (BBE-P) parameter for each Low Order Path is monitored. The number of Far-End VC-n BBE-Ps in a one second period is equal to the
F_EBC if the second is not a Far-End SES and if the second is not a N_DS. Otherwise, the Far-End BBE-P is set to zero for that second.
ITU-T standards refers to this parameter as F_BBE, but for consistency within the
Alcatel-Lucent 1665 DMX product, this parameter is referred to as BBE-P with a locn value of FEND to indicate that it is the Far-End Background Block Errors.

Errored seconds (ES-P)
The Near-End VC-n Errored Seconds (ESP) parameter for each Low Order VC-n is monitored. A Near-End VC-n ES parameter increments for each second in which there is one or more N_Bs (detected at the Low Order Path Layer) or a N_DS defect is present.
ITU-T standards refers to this parameter as N_ES, but for consistency within the
Alcatel-Lucent 1665 DMX product, this parameter is referred to as ES with a locn value of NEND to indicate that it is the Near-End Errored Seconds.
The Far-End VC-n Errored Seconds (ESP) parameter for each Low Order VC-n Path is monitored. A Far-End VC-n ES parameter increments for each second in which the
Far-End errored block count (F_EBC) is equal to or greater than 1 or when at least one
F_DS defect is present for that second, and there is no N_DS present for that second.
ITU-T standards refers to this parameter as F_ES, but for consistency within the
Alcatel-Lucent 1665 DMX product, this parameter is referred to as ES with a locn value of FEND to indicate that it is the Far-End errored seconds.
Severely errored seconds (SES-P)
The Near-End VC-n Severely Errored Seconds (SESP) parameter for each Low Order
VC-n is monitored. An Near-End VC-n SES parameter increments for each second in which the N_EBC is equal to or greater than K, or an N_DS defect is present. The integer value for K is set by standards (values are shown in Table 9). ITU-T standards refers to this parameter as N_SES, but for consistency within the Alcatel-Lucent 1665 DMX product, this parameter is referred to as SES with a locn value of NEND to indicate that it is the Near-End Severely Errored Seconds parameter.
The Far-End Severely Errored Seconds (SESP) parameter for each Low Order VC-n Path is monitored. A Far-End VC-n SES parameter increments for each second in which the
Far-End errored block count (F_EBC) is equal to or greater than K or at least one F_DS defect is present for that second, and there is no N_DS defect present for that second. The integer value for K is set by standards (values are shown in Table 9).
ITU-T standards refers to this parameter as F_SES, but for consistency within the
Alcatel-Lucent 1665 DMX product, this parameter is referred to as SES with a locn value of FEND to indicate that it is the Far-End Severely Errored Seconds.
Unavailable seconds (UAS-P)
The Near-End VC-n Unavailable Seconds (UASP) parameter for each Low Order Path is monitored. The Near-End VC-n UAS parameter increments once for every second that the Low Order Path was considered unavailable (at any point during the second). A Low
Order Path becomes unavailable at the onset of 10 consecutive seconds that qualify as
Near-End VC-n SESP, and continues to be unavailable until the onset of 10 consecutive seconds that do not qualify as Near-End VC-n SES.

The (un)available time can not be determined if it is unknown whether the previous 10 seconds are Severely Errored on non-Severely Errored. Thus the SES must be processed to determine whether the SES are consecutively present or absent. ITU-T standards refers to this parameter as N_UAS, but for consistency within the Alcatel-Lucent 1665 DMX product, this parameter is referred to as UAS with a locn value of NEND to indicate that it is the Near-End Unavailable Seconds.
The Far-End Unavailable Seconds (UASP) parameter for each Low Order Path is monitored. The Far-End VC-n UAS parameter increments once for every second that the
Far-End Low Order Path was considered unavailable (at any point during the second). A
Far-End Low Order Path becomes unavailable at the onset of 10 consecutive seconds that qualify as Far-End VC-n SESs, and continues to be unavailable until the onset of 10 consecutive seconds that do not qualify as Far-End VC-n SESs.
The (un)available time cannot be determined if it is unknown whether the previous 10 seconds are Severely Errored on non-Severely Errored. Thus the Far-End VC-n SES must be processed to determine whether the Far-End VC-n SES are consecutively present or absent.

Failure counts path (FC-P)
The Near-End VC-n Path Failure Counts (FC-P) parameter for each Low Order path is monitored. The FC-P parameter increments once for the beginning of each TU-AIS event
(TU-AIS detected and cleared), TU-LOP event (TU-LOP detected and cleared),
LP-UNEQ event (LP-UNEQ detected and cleared), HP-LOM event (HP-LOM detected and cleared). A failure that begins in one period and ends in another period, is counted in the period in which it begins.
The Far-End VC-n Path Failure Counts (FC-P) parameter for each Low Order path is monitored. The VC-n Far-End FC-P parameter increments once for the beginning of each
RDI event (RDI detected and cleared). A failure that begins in one period and ends in another period, is counted in the period in which it begins.

OC-N section parameter
Alcatel-Lucent 1665 DMX monitors the following near end SONET section parameters for incoming (from the lightguide cross-connect) OC-N signals. The parameters are measured at the input of the OC-N OLIU circuit pack on the line side (also referred to as
LGX side).
Coding violations (CV-S)
The Section Coding Violations (CV-S) parameter for each SONET section is monitored.
The CV-S parameter is a count of BIP errors at the Section Layer (i.e., B1 errors). Up to eight Section BIP errors can be detected per STS-N frame, each error increments the
CV-S current second register.
Errored seconds (ES-S)
The Section Errored Seconds (ESS) parameter for each SONET section is monitored. The
ESS parameter increments once for each second in which at least one Section Layer BIP error was detected or an SEF or LOS defect was present.

OC-N line parameters
Alcatel-Lucent 1665 DMX monitors the following near end SONET line parameters for incoming (from the lightguide cross-connect) OC-N signals. The parameters are measured at the input of the OC-N OLIU circuit pack on the OC-N line side (also referred to as
LGX side).
Coding violations (CV-L)
The Near-End Line Coding Violation (CVL) parameter for each SONET Line is monitored. The Near-End CVL parameter increments once for every occurrence of a BIP error detected at the Line layer (i.e. using the B2 byte in the incoming SONET signal). Up to 8*N BIP errors can be detected per STS-N frame.
Errored seconds (ES-L)
The Near-End Line Errored Seconds (ESL) parameter for each SONET Line is monitored. The Near-End CVL parameter increments once for every second that contains at least one BIP error detected at the Line layer (at any point during the second), or an
AIS-L defect was present.
Severely errored seconds (SES-L)
The Near-End Line Severely Errored Seconds (SESL) parameter for each SONET Line is monitored. The Near-End SESL parameter increments once for every second that contains at least K BIP errors detected at the Line layer (at any point during the second), or an
AIS-L defect was present. The value of K is hard-coded, see table 7 for a list of the values
Unavailable seconds (UAS-L)
The Near-End Line Unavailable Seconds (UASL) parameter for each SONET Line is monitored. The Near-End UASL parameter increments once for every second that the
Line was considered unavailable (at any point during the second). A Line becomes unavailable at the onset of 10 consecutive seconds that qualify as Near-End SESLs, and continues to be unavailable until the onset of 10 consecutive seconds that do not qualify as Near-End SESLs.

Far-end line failure counts (FC-L)
The Far-End Line Failure Counts (FC-L) parameter for each SONET line is monitored.
The Far-End FC-L parameter increments once for the beginning of each RFI-L event
(RFI-L detected and cleared). A failure that begins in one period and ends in another period, is counted in the period in which it begins.
Protection switch count (PSC-L)
The PSC parameter records the number of times that service traffic switched to or from another line either automatically, by a WaveStar
®
CIT command, or operations system command. The Near-End Protection Switch Counts (PSC-L) parameter for each SONET line (that supports 1+1 protection switching for that line) is monitored. Separate PSC counters is provided for differentiating between working and protection for each SONET line that supports 2F BLSR for that line. In a 2 Fiber ring, two separate PSC counts are maintained for the working and protection fibers in a given line. These parameters are defined as PSC-W and PSC-P for Protection Switch Counts-Working and Protection
Switch Counts-Protection respectively.
Pointer justifications counts difference (PJCDIFF-P)
This is a calculation of the absolute value of the PJC parameters listed under the headings below. PJCDIFF-P is used to calculate the difference between calculate the difference between the PPJC-PGEN, NPJC-PGEN and between PPJC-PDET and NPJC-PDET.
Alcatel-Lucent 1665 DMX monitors the first cross-connected STS. From this STS, the calculation is to (A) calculate the difference between the PPJC-PGEN, NPJC-PGEN. (B)
Calculate the difference of the PPJC-PDET, NPJC-PDET. The resulting PJC is the absolute value of the difference between A and B.
Negative pointer justifications counts detected (NPJC-PDET)
This parameter summarizes all Negative Pointer Justifications detected by the system.
Alcatel-Lucent 1665 DMX monitors negative line Pointer Justifications on an STS-1 within the OC-n line in 1 second intervals. (Users may select which STS-1 to monitor by provisioning the PJC Monitoring point parameter using the
Performance
→ Provision
PM
command.) The count increments for each incoming negative STS pointer justification.
Positive pointer justifications counts detected (PPJC-PDET)
This parameter summarizes all Positive Pointer Justifications detected by the system.
Alcatel-Lucent 1665 DMX monitors positive line Pointer Justifications on an STS-1 within the OC-n line in 1 second intervals. (Users may select which STS-1 to monitor by provisioning the PJC Monitoring point parameter using the
Performance
→ Provision
PM
command.) The count increments for each incoming positive STS pointer justification.

STS-N performance parameters
Overview
This section describes the performance monitoring parameters on terminated (STS-1) and intermediate STS-N (STS-1, STS-3c, STS-12c) paths that are cross-connected through the system. Intermediate SONET STS-N path performance monitoring applies to STS-N paths cross-connected to another SONET interface. Terminated SONET STS-N path performance monitoring applies to STS-N paths cross-connected to a non-SONET interface (for example, DS3).

Alcatel-Lucent 1665 DMX monitors the following near end SONET STS path parameters on incoming (from the SONET interface) STS-N signals.
Coding violations (CV-P)
The Near-End STS Path Coding Violations (CVP) parameter for each SONET path is monitored. The CVP parameter increments once for each BIP error detected at the STS path layer (the B3 byte of the incoming SONET STS Path overhead). Up to 8 BIP errors can be detected per frame.
The Far-End STS Path Coding Violations (CVP) parameter for each SONET path is monitored. The Far-End CVP parameter increments as reported by the REI-P indication of the STS path overhead.
Errored seconds (ES-P)
The Near-End STS Path Errored Seconds (ESP) parameter for each SONET path is monitored. The ESP parameter increments once for each second where one or more STS
Path layer BIP errors are detected or an AIS-P, LOP-P, or UNEQ-P defect is detected.
The Far-End STS Path Errored Seconds (ESP) parameter for each SONET path is monitored. The Far-End ESP parameter increments once for each second where one or more Far-End STS Path layer BIP errors are detected as reported by the REI-P indication of the line overhead or an RDI-P defect is present, or an ERDI-P (if supported) defect is detected.
Alcatel-Lucent 1665 DMX detects 1-bit RDI, but treats it as though it is the high order bit of a 3-bit ERDI in that it includes UNEQ.
Severely errored seconds (SES-P)
The Near-End STS Path Severely Errored Seconds (SESP) parameter for each SONET path is monitored. The SESP parameter increments once for each second where K or more STS Path layer BIP errors are detected or an AIS-P, LOP-P, or UNEQ-P defect is detected. The integer value for K is set by standards and is selectable (values are shown in
Table 8). Alcatel-Lucent 1665 DMX detects 1-bit RDI, but treats it as though it is the high order bit of a 3-bit ERDI in that it includes UNEQ.

Coding violations (CV-L)
The Near-End Line Coding Violation (CVL) parameter for each SONET Line is monitored. The Near-End CVL parameter increments once for every occurrence of a BIP error detected at the Line layer (i.e. using the B2 byte in the incoming SONET signal). Up to 8*N BIP errors can be detected per STS-N frame.
Errored seconds (ES-L)
The Near-End Line Errored Seconds (ESL) parameter for each SONET Line is monitored. The Near-End CVL parameter increments once for every second that contains at least one BIP error detected at the Line layer (at any point during the second), or an
AIS-L defect was present.
Severely errored seconds (SES-L)
The Near-End Line Severely Errored Seconds (SESL) parameter for each SONET Line is monitored. The Near-End SESL parameter increments once for every second that contains at least K BIP errors detected at the Line layer (at any point during the second), or an
AIS-L defect was present. The value of K is hard-coded, see table 7 for a list of the values
Unavailable seconds (UAS-L)
The Near-End Line Unavailable Seconds (UASL) parameter for each SONET Line is monitored. The Near-End UASL parameter increments once for every second that the
Line was considered unavailable (at any point during the second). A Line becomes unavailable at the onset of 10 consecutive seconds that qualify as Near-End SESLs, and continues to be unavailable until the onset of 10 consecutive seconds that do not qualify as Near-End SESLs.
Far-end line failure counts (FC-L)
The Far-End Line Failure Counts (FC-L) parameter for each SONET line is monitored.
The Far-End FC-L parameter increments once for the beginning of each RFI-L event
(RFI-L detected and cleared). A failure that begins in one period and ends in another period, is counted in the period in which it begins.
Pointer justifications counts difference (PJCDIFF-P)
This is a calculation of the absolute value of the PJC parameters listed under the headings below. PJCDIFF-P is used to calculate the difference between calculate the difference between the PPJC-PGEN, NPJC-PGEN and between PPJC-PDET and NPJC-PDET.
Alcatel-Lucent 1665 DMX monitors the first cross-connected STS. From this STS, the calculation is to (A) calculate the difference between the PPJC-PGEN, NPJC-PGEN. (B)
Calculate the difference of the PPJC-PDET, NPJC-PDET. The resulting PJC is the absolute value of the difference between A and B.

Ethernet parameters
Alcatel-Lucent 1665 DMX monitors several Ethernet parameters.
Ethernet dropped frames (congestion) (EDFC)
The EDFC parameter counts the number of incoming Ethernet frames dropped at a specific LAN/WAN port due to buffer overflow. Buffer overflow occurs when the network is congested.
For LNW170, this count represents the number of frames that could not be transmitted on the specified port because of congestion. For all other circuit packs, this count represents the number of frames that could not be received on the specified port because of congestion. This parameter does not apply to the LNW74 circuit pack.
Ethernet dropped frames (errors) (EDFE)
The EDFE parameter counts the number of incoming Ethernet frames dropped at a
LAN/WAN port due to a frame check sequence (FCS) error or another defect in the frame.
For the LNW73: this count represents frames received with invalid CRC on data port. For
VCG, this count represents dropped GFP super-block frames due to CRC error.
This parameter is valid only for VCGs; not valid for LAN ports.
Ethernet dropped frames (policer) (EDFP)
This parameter is valid only for VCGs - not LAN ports.

Performance monitoring data storage
Quarter-hour and current day registers
For each parameter supported, Alcatel-Lucent 1665 DMX provides one current
15-minute, one current day, one previous 15-minute, one previous day, and 32 recent
15-minute accumulation and storage registers.
Access/Initialization
Alcatel-Lucent 1665 DMX can initialize these registers through the TL1 interfaces at any time, as well as retrieve and report their contents.
The registers are not initialized by a shelf restart (unless caused by a power failure).
Performance parameter thresholds
Provisioning
The current quarter-hour and current day thresholds for each parameter type are provisionable, on a per-shelf basis (PSD-L, FC-L, and FC-P do not have thresholds). If values other than the defaults are used, only one value for each parameter type needs to be set.
The FC-DATA packs (LNW73 and LNW73C SAN interfaces) provide a different set of parameters. For more information on the parameters supported by these packs, see
“Performance monitoring” (p. 5-64) .
Threshold crossing alerts (TCAs)
Whenever the current quarter-hour or the current day threshold for a given parameter is exceeded, Alcatel-Lucent 1665 DMX generates a threshold-crossing alert (TCA) that is entered into the performance monitoring exception report and reported to the OS through the TL1 interface.

Interface Index
Interface description (mfg, product, version)
Type of interface
Interface maximum rate (bps) - for GbE circuit pack, this is
“1,000,000,000”, for FE circuit pack, value is based on value of the line rate parameter. If the line rate is 10M, ifSpeed value is “10,000,000”. If the line rate parameter is 100M, ifSpeed value is “100,000,000”.
MAC Address
Administration status (up, down or testing) (read only). Value is always
“up”.
Operational status (up, down, testing, unknown, dormant, notPresent or lowerLayerDown). If board/port is removed, value is “notPresent”. If there is an existing alarm on the port, i.e., Loss of signal (LOS) or
Auto-Negotiation Mismatch (ANM) on the port, then the value is
“down”, else the value is “up”.

Overview
Purpose
Alcatel-Lucent 1665 DMX allows the user to customize many system characteristics through provisioning features. Provisioning parameters are set by software controls.
This section describes the many types of provisionable parameters available in
Alcatel-Lucent 1665 DMX.

Automatic provisioning on circuit pack replacement
Default provisioning
Default values
Installation provisioning is minimized with thoughtfully chosen default values set in the factory. Every parameter has a factory default value. These factory defaults for software parameters are maintained in the SYSCTL circuit pack, and a single command is provided to restore all default values. The original values assigned at the factory cannot be changed. However, the current values can be overridden through local or remote provisioning. All provisioning data is stored in nonvolatile memory to prevent data loss during power failures and maintenance operations.
A parameter is a characteristic of the system that affects its operation. The parameter value may be a number, text string, or other menu selection.

Remote provisioning
Overview
Software control allows remote provisioning of Alcatel-Lucent 1665 DMX NEs. This feature is provided especially for provisioning parameters likely to change in service, in support of centralized operations practices.
Cross-connection provisioning
Overview
Alcatel-Lucent 1665 DMX can be provisioned for signal routing. Depending on the application, VT1.5, STS-1, STS-3(c), STS-12(c), STS-48(c), or STS-192(c) signal cross-connections may be established to route traffic in a specific manner.
Cross-connections may be bidirectional or unidirectional.
Alcatel-Lucent 1665 DMX employs atomic cross-connections for all cross-connection provisioning. Atomic cross-connections are one-way cross-connections between logical ring channels which can be set up and taken down by a single command, and which cannot be broken down into smaller parts. Logical ring channels are the tributaries of a port or port protection group used for transmission in the absence of any line or equipment protection.
Atomic cross-connections are more flexible than the cross-connection provisioning structure employed previously. They allow for the support of more detailed applications because you are able to provision each portion of a cross-connection.
Typical cross-connections
Any VT1.5 or STS-n signal may be provisioned for the following signal routes:
• Main to Main
• Main to Function Unit.
• Hairpin (Function Unit to Function Unit).
Alcatel-Lucent 1665 DMX supports unidirectional cross-connections.
STS-1 cross-connections to Ethernet interfaces are also available. The 1WAY and
1WAYPR cross-connection is used for UPSR point-to-point Ethernet applications. A
1WAY UNSWITCHED cross-connection is used for multipoint Ethernet applications.
The unidirectional pass-through cross-connection is used to pass VT1.5 or STS-n signals through the NE all on the same time slot. For pass-through cross-connections, the channel state default is NMON rather than AUTO as with other cross-connections.

OCH cross-connections
Alcatel-Lucent 1665 DMX also supports optical channel (OCH) cross-connections between dense wavelength division multiplexing (DWDM) compatible circuit packs/pluggable transmission modules. The OCH cross-connections are used to inform the network element about manual fiber connections.
The following OCH cross-connections are supported:
• DWDM-compatible OC-192 port to/from OCH port
• OTU2 port to/from OCH port
• Remote DWDM-compatible wavelength (remote shelf) to/from OCH port
• OCH port to/from OCH port (pass through)

Automatic provisioning on circuit pack replacement
Overview
Replacement of a failed circuit pack is simplified by automatic provisioning of the original circuit pack values. A provisioning map for the entire shelf is stored redundantly within the SYSCTL (LNW2).
Auto provisioning
Auto provisioning is the ability of an NE to detect the presence of equipment, validate it, and then assign default original values or pre-provisioned parameter values to new equipment. Nonvolatile memory (NVM) and/or hardware registers maintain the parameter values. If you have predefined or pre-provisioned some or all of the parameters, the auto provisioning function validates the request and assigns the pre-provisioned values or default values as required. Auto-provisioning allows an NE to be set up initially with minimal user intervention. Auto-provisioning also supports a self inventory function which allows operations center personnel to learn about and track activities at a remotely located NE.
Automatic provisioning on circuit pack replacement
When a failed circuit pack is replaced, it is automatically provisioned with the original circuit pack values. The provisioning map for the entire shelf is stored redundantly within the SYSCTL (LNW2). It doesn't need to be uploaded from other packs. In order to

replace the LNW2, remove the NVM from the old LNW2 and place it in the new LNW2.
Alternatively, you may backup the database, install a factory-fresh LNW2 (with new
NVM cards), enter maintenance mode, download the generic, and restore the database.
Items auto provisioned
Some items that are auto-provisioned include the following:
• System target identifier (TID) (which can be changed at initial start-up)
• Default threshold-crossing alert (TCA) profiles
• Circuit packs
• Synchronization default mode
Equipment removal
The NE detects and reports the removal of equipment. The removal of equipment does not cause the NE to delete any entities. Removal of a piece of equipment may result in equipment alarms and insertion of maintenance signals when the state related data is updated. However, removal of equipment does not necessarily mean that the provisioning of the shelf slot has changed. The user must execute specific commands to remove an entity from the system database.
Port state provisioning
Overview
Port state provisioning is a feature provided on Alcatel-Lucent 1665 DMX NEs that can help suppress alarm reporting and performance monitoring by supporting multiple states for DS1, DS3, E1, EC-1, OTS, OCH,OTU2, and Ethernet LAN ports.
The DS1, DS3, E1, EC-1, OTS, OCH, OTU2 port states are:
• automatic (OOS-MA-AS)
• in-service (IS)
• not monitored (OOS).
Ethernet LAN port states are:
• automatic (AUTO)
• in-service (IS)
• not monitored (NMON).

Port states
Ports without signals (undriven) are in the automatic state until changed to the in-service state. Ports are changed to the in-service state when a signal is present or they can be provisioned as in-service by the user. Commands allow a user to retrieve and change the state of a port to the not-monitored state or from the not-monitored state to the automatic state.
Client port (LNW705) primary states follow the rules of their provisioned signal type.
Channel state provisioning
Overview
Automatic channel state provisioning is a capability provided on Alcatel-Lucent 1665
DMX NEs that suppresses reporting of transient alarms and events during provisioning by supporting multiple states (see previous section) for VT1.5, VC-12, STS-1, STS-3(c),
STS-12(c), STS-48(c), or STS-192(c) channels.
Automatic channel state provisioning
While an end-to-end circuit is being set up, particularly during VT1.5/VC-12 and STS-n cross-connection provisioning, several transient maintenance signals result. Without automatic channel state provisioning, these are reported as alarms and events. The technicians are expected to ignore these transient alarms and initiate corrective action only if the alarms persist after the provisioning is completed. To avoid the confusion created by this, Alcatel-Lucent 1665 DMX provides automatic channel state provisioning.
Channel states
A VT1.5 or STS-n channel is kept in the default automatic (OOS-MA-AS) state until the reception of a valid signal (for STS channel states, a valid signal is one free of LOP-P,
AIS-P, UNEQ-P, and SF-- for VT channel states, a valid signal is one free of LOP-V,
AIS-V, and UNEQ-V.) in that channel. While in OOS-MA-AS state, no alarms or events are reported on the channel. On receiving a valid signal, which occurs when the end-to-end circuit is completely provisioned, the channel automatically changes to the in-service (IS) state, where it resumes normal alarm and event reporting. An additional state, not-monitored (OOS), is also supported in which alarm and event reporting is suppressed regardless of the validity of the signal being received on the channel. Like the port state provisioning capabilities already provided for physical ports like DS1, DS3, and
EC-1, the user can submit commands to manually change a channel from IS or
OOS-MA-AS to OOS, and from OOS to OOS-MA-AS. A user cannot manually change from OOS-MA-AS or OOS to IS.

Channel state provisioning
....................................................................................................................................................................................................................................
For pass-through cross-connects, the channel state transitions from OOS-MA-AS to OOS upon receiving a good signal. This is different than what happens on dropped tribs. On dropped tributaries, the channel state automatically transitions from OOS-MA-AS to IS upon receiving a good signal.
Note: LOP-P is reported regardless of channel state. STS LOP (LOP-P) is reported on any cross-connected tributary, even when the STS channel state is HOSANNAS or
OOS. For BLSR, LOP-P is also reported on all working and protection tributaries, independent on whether or not there is a cross-connect.
Line state provisioning
Overview
The state of the low-speed OC-3/12/48 and the high-speed OC-12/48/192 ports can be set manually to not monitored (OOS). On OLIUs with multiple ports, the line state default is automatic (OOS-MA-AS). It is also possible to manually provision any equipped line to in-service (IS).
For more information about the AUTO line state, see

A description of the condition (for example, controller failure, incoming high-speed signal failure, synchronization hardware or reference failure, etc.) is included in the reports along with a time stamp indicating when the condition was detected, its severity, and whether it is service affecting or not. The option to display specified subsets of alarm conditions is provided (for example, critical alarms only).
Circuit pack status conditions
Circuit pack status conditions include:
• Manually initiated abnormal conditions (for example, forced switch, manual lockouts, loopbacks, system testing)
• Incoming AIS detected
• ACO active.
A description of the status condition (for example, DS1 loopback active, DS3 facility loopback active, etc.) is included in the report along with a time stamp indicating when the condition began.

Alcatel-Lucent 1665 DMX supports of Alarm Severity Assignment Profiles (ASAPs).
With ASAPs, any alarm supported for a particular circuit pack/interface can also be a status condition.
Performance monitoring reports
TCA summary report
Alcatel-Lucent 1665 DMX provides a report that lists the number of SONET performance-monitoring parameters that have crossed their thresholds. This report provides a snapshot of the system performance level. If there is signal degradation, it is quickly pinpointed so that corrective action may be taken before customers are affected, thus supporting proactive maintenance.
This report provides separate parameter summaries for each signal level in the system, including SONET section, line, and path, as well as dropped/incoming/outgoing Ethernet bytes and frames. The parameter summaries show the user which performance status to request if they want further information.
Performance status reports
These reports provide detailed information on the current and previous 8 hours in quarter-hour (15-minute) increments, as well as the current and previous day's performance. Threshold crossing alerts are clearly identified and the time the performance registers were last initialized is also shown. Any registers that may have been affected by this initialization are marked. There are separate reports for section, line, and path parameters, as well as Ethernet parameters.
Maintenance history reports
Overview
A maintenance history report contains the following past conditions:
• alarms
• status
• protection switching
• user interface commands (e.g., provisioning, loopback request, manual protection, etc.)

365-372-301, for details on the history log.
State reports
Overview
The state report shows the protection state of all circuit packs installed in the system and the state of the individual low/high-speed channels.
Circuit pack states
The circuit pack state is reported as "active" or "standby."
Path states
The state of the individual VT1.5/VC-12 /STS-n channels and paths may be one of the following:
• not monitored (NMON)
• in service (IS)
• auto (AUTO).
The system reports this information on all interfaces. For VT1.5/VC-12/STS-n channels and paths, the AUTO state would transition to the IS state if a good signal is detected.
Line and port states
The state of individual lines may be IS, NMON, or AUTO for all OC-n ports.

Software upgrades
Overview
Alcatel-Lucent 1665 DMX provides an in-service software installation capability to update the generic program in local and remote systems. Upgrades are distributed on
CD-ROMs containing the new software and an installation program. These software upgrades are the primary mechanism to add new feature enhancements to the in-service
Alcatel-Lucent 1665 DMX network.
Beginning in R6.0, Alcatel-Lucent 1665 DMX employs provisionable alarm severity profiles known as ASAPs. Therefore, previous alarm severity level provisioning is lost when upgrading to R6.0. Also, because R6.0 introduces atomic cross-connections, any existing 2WAY, 2WAYPR, and MLTPT cross-connects will be automatically replaced with equivalent 1WAY, 1WAYPR, and UNSWITCHED cross-connects.

Software download
In the Alcatel-Lucent 1665 DMX system, software download takes place in two stages. In the first stage, the new generic software is downloaded into a dormant "flash" area as a compressed file. In the second stage, the new generic is uncompressed and moved into an active "flash" space. During this process, the old release continues to run from random access memory (RAM). Installation is not service-affecting, so down time is limited to the reboot time.
Note: During the database initialization phase of the SYSCTL startup, the
ACO
LED is continuously lighted and the
FAULT
LED flashes. Following completion of the database initialization, the
ACO
and
Fault
LEDs return to their normal operation.
Local installation procedure
The procedure is straightforward. The technician connects a personal computer (PC) to the IAOLAN port on the local Alcatel-Lucent 1665 DMX, starts the installation program, and is prompted with a few warnings before the upgrade installation actually begins. After the technician confirms to proceed, the PC takes over the process and completes the installation.
Installation may also be performed via Alcatel-Lucent's OMS or CIT over the IAO LAN interface using FTP or FTAM.

IP Access for network management
Overview
For network management purposes, Alcatel-Lucent 1665 DMX supports the following types of IP Access:
• Alcatel-Lucent 1665 DMX can serve as a TL1 Translation Device (T-TD) by acting as a gateway network element that allows OMS and/or WaveStar
®
CIT to communicate to other network elements (NEs) through an IP access network. This capability allows you to send TL1 commands from OMS or WaveStar
®
CIT located on a TCP/IP based network to various NEs connected on an OSI network.
• Alcatel-Lucent 1665 DMX can functionally encapsulate IP packets within OSI packets to be transmitted through the OSI network to the proper NE. Thus
Alcatel-Lucent 1665 DMX supports IP based protocols such as FTP by providing end-to-end IP connectivity between OS and NE. This capability is called IP tunneling.
IP tunneling is required to support remote database backup/restore in between
Alcatel-Lucent 1665 DMX systems.
• Alcatel-Lucent 1665 DMX can also serve as a File Transfer Translation Device
(FTTD) by acting as an FTAM-FTP gateway network element. The FTAM-FTP gateway network element translates FTAM over OSI presentation to FTP over
TCP/IP. The FTAM-FTP gateway supports software downloads, database backups, and database restores.
• Alcatel-Lucent 1665 DMX also supports Simple Network Management Protocol
(SNMP). Alcatel-Lucent 1665 DMX provides limited support for certain reports and traps (alarms and events autonomous messages).
• Alcatel-Lucent 1665 DMX also supports Network Time Protocol (NTP) using IP tunneling to synchronize the time and date to a standard time reference.
TL1 GNE (T-TD)
Alcatel-Lucent 1665 DMX can copy the application information within an IP packet into an OSI packet. This translation is performed at the application layer. When acting as a
TL1 translation device, Alcatel-Lucent 1665 DMX must be provisioned with a list of

possible OSs. If an OS is not on the list residing within the system, a connection from that
OS will not be accepted. When Alcatel-Lucent 1665 DMX is used as a TL1 translation device it is referred to as the T-TD GNE (Gateway Network Element).

OSI associations and TCP/IP connections
When used as a GNE, Alcatel-Lucent 1665 DMX supports a total of 300 OSI associations
(logins). Each TCP/IP (or Telnet) connection can support 300 associations. The
Alcatel-Lucent 1665 DMX GNE supports up to 20 TCP/IP connections. The combined number of OSI associations on all TCP/IP sessions cannot exceed 300.
IP tunneling
Today, Telecom networks mix a wide range of heterogeneous protocols and applications.

The Alcatel-Lucent IP tunneling solution consists in encapsulating IP packets inside
CLNP (ISO 8473 ConnectionLess Network Protocol) PDU, in order to be able to use an existing OSI-based embedded Data Communications Network (DCN) for IP traffic.
With the IP tunneling over CLNP solution, Alcatel-Lucent 1665 DMX NE can support the following two customer applications: IP access and IP fringe.
An IP access application is shown in
Figure 5-19, “IP tunneling” (p. 5-164) , where an IP
based OS (for example, SNMP manager) located in the IP access DCN manages a remote
Alcatel-Lucent 1665 DMX NE located in the OSI-based embedded DCN. The IP application initiated at the OS terminates at the remote NE.

An IP fringe application, where an IP based OS located in the IP access DCN manages an
IP managed NE (non Alcatel-Lucent 1665 DMX) on the fringe of Alcatel-Lucent 1665
DMX OSI-based embedded DCN. The IP application initiated at the OS terminates at the
IP managed NE. If the IP managed NE is not directly connected to Alcatel-Lucent 1665
DMX remote NE via the LAN, but can be reached via additional routers, some static routes have to be provisioned manually on the routers.
Alcatel-Lucent 1665 DMX and Alcatel-Lucent 1850 TSS-100/Alcatel-Lucent 1850
TSS-320 IP tunneling interworking
In a typical network, the Alcatel-Lucent 1665 DMX is a remote NE (RNE) interworking with an Alcatel-Lucent 1850 TSS-100 or Alcatel-Lucent 1850 TSS-320 functioning as the gateway NE (GNE). The Alcatel-Lucent 1850 TSS-100/Alcatel-Lucent 1850 TSS-320
GNE supports T-TD (TL1 Translation Device) to translate TL1 over TCP/IP to TL1 over
OSI. This allows TL1 management of a remote Alcatel-Lucent 1665 DMX.
However, to fully support IP tunneling interworking between a remote Alcatel-Lucent
1665 DMX and the Alcatel-Lucent 1850 TSS-100/Alcatel-Lucent 1850 TSS-320 GNE,
Alcatel-Lucent 1665 DMX supports a provisionable NSAP selector and a reduced
Maximum Transmission Unit (MTU) size.
To support interworking with the Alcatel-Lucent 1850 TSS-100/Alcatel-Lucent 1850
TSS-320, the NSAP selector parameter must be provisioned to f0 (04 default value) at the remote Alcatel-Lucent 1665 DMX. This allows software operations
(download/backup/restore) to a remote Alcatel-Lucent 1665 DMX using FT-TD (File
Transfer Translation Device) to translate FTP over TCP/IP to FTAM over OSI.
Encapsulating IP packets
The Alcatel-Lucent 1665 DMX GNE acts as the tunnel entrance, i.e., the interface between IP and CLNP. When an IP packet is received from the LAN interface of the
GNE, if it is not destined for the GNE, the received IP packet is encapsulated into CLNP
PDU(s) as simple CLNP user data, loosing any IP protocol meanings (such as IP addressing and life time), as shown in the figure below.

For the CLNP PDU that contains the encapsulated IP packet, the CLNP source address is the NSAP of the NE where the IP packet is encapsulated (tunnel entrance), and the CLNP destination address is the NSAP of the NE where the IP packet will be de-capsulated
(tunnel exit). The CLNP PDU then is routed via the ISO-10589 "IS to IS intra-domain information exchange protocol (IS-IS)" within the embedded OSI DCN. Therefore, the IP tunneling over CLNP is transparent for the IP world. The CLNP world is only used to carry the IP traffic and there is no possible connections between the OSI applications and the IP applications. The IP tunnel serves as a normal point-to-point link for the IP traffic between two NSAP entities (the tunnel entrance and tunnel exit). Because the IP traffic flows in both directions between two NSAP entities, the tunnel entrance entity also serves as the tunnel exit entity, and vice versa.
In the tunnel entrance, the way to associate an IP destination address in the IP packet with an OSI NSAP address (the NSAP of tunnel exit entity) can be derived by the static user provisioned information or by the automatic distributed tunnel routing information, called
Tunnel Auto Provisioning (TAP).
Tunnel auto provisioning (TAP)
In the OSI networks, the network elements use the ISO-10589 "IS to IS intra-domain information exchange protocol (IS-IS)" to exchange the topology information. The knowledge by every network element of the whole network topology at a given time allows the computation of the optimal route to any possible destination on the network.
The IS-IS protocol provides for the inclusion of optional variable length fields in all IS-IS packets. This allows additional IP specific information to be added to the OSI IS-IS routing packets.
The topological information between network elements (or called intermediate systems) is communicated by sending a specific IS-IS PDU called LSP (Link-State PDU). In the
LSP optional fields, the NEs send (advertise) information about the IP subnets that can be reached via that NE. By default, this will be locally attached, but other subnets can also be provisioned for the advertisement.
Advertising IP information using LSP options can be enabled or disabled via the user interfaces. Based on the specification of the IS-IS protocol, any intermediate systems that can not recognize the encoded optional fields just ignores this and passes them through unchanged. This makes it possible that the NEs that advertise both OSI and IP routing information can seamlessly interwork with the NEs that advertise the OSI routing information only.
With automatic distribution of IP routing information via IS-IS LSP, a NE, which learned such information, then can associate an IP destination address of an IP packet with an OSI
NSAP address, and uses this NSAP address as the destination address of CLNP PDU(s) which encapsulates the IP packet.

FTAM-FTP gateway network element
Alcatel-Lucent 1665 DMX can serve as a File Transfer Translation Device (FTTD) by acting as an FTAM-FTP gateway network element. The FTAM-FTP gateway network element translates FTAM over OSI presentation to FTP over TCP/IP. The FTAM-FTP gateway supports software downloads, database backups, and database restores.
The figure below shows an Alcatel-Lucent 1665 DMX provisioned as an FTAM-FTP gateway network element. The FTAM-FTP gateway network element allows remote
Alcatel-Lucent 1665 DMX network elements to request software downloads and database restores from an FTP server. The FTAM-FTP gateway network element also allows remote Alcatel-Lucent 1665 DMX network elements to backup databases to an FTP server.

IP over DCC
The sections above described how Alcatel-Lucent 1665 DMX can act as a GNE providing
FTTD and TTD functionality. If there is no Alcatel-Lucent 1665 DMX in a particular office where GNE can connect, via IAO LAN interface, to the IP WAN, these options can prove ineffective. For this reason Alcatel-Lucent 1665 DMX incorporates IP communications over the DCC channel. This feature allows operations communications to flow through another device (like Ciena Core Director) to the Alcatel-Lucent 1665
DMX GNE via an IP over DCC link. This feature also enables interworking with Ciena
Core Director (CD).
Management traffic flow (OMS to Alcatel-Lucent 1665 DMX)
OMS originates IP packets destined to Alcatel-Lucent 1665 DMX GNE, and uses Router
R1 as the Default Router. Router R1 routes the packets via IP access DCN to Router R2.
Router R2 forwards the packets to CD via Proxy ARP supported by CD. Based on the static routing, CD forwards the IP packets to Alcatel-Lucent 1665 DMX GNE via IP over
DCC link. Alcatel-Lucent 1665 DMX GNE translates IP messages to OSI messages and routes CLNP packets to the remote NE (RNE) via OSI embedded DCN.
Management traffic flow (Alcatel-Lucent 1665 DMX to OMS)
Alcatel-Lucent 1665 DMX RNE originates CLNP packets destined to Alcatel-Lucent
1665 DMX GNE, and routes CLNP packets to Alcatel-Lucent 1665 DMX GNE via OSI embedded DCN. The Alcatel-Lucent 1665 DMX GNE translates OSI messages to IP messages, and originates IP packets destined to OMS. Based on static routing, the
Alcatel-Lucent 1665 DMX GNE uses the IP over DCC link to forward the IP packets to the CD. CD forwards the IP packets to Router R2 via default routing provisioned by user.
Router R2 routes the IP packets via IP access DCN to Router R1.Router R1 forwards the
IP packets to OMS.

Access control list
The access control list adds a layer of control in addition to the TL1 user ID and password. When the access control list is enabled, an IP-based OS can log in to a remote target NE via a GNE (T-TD) only if the GNE, represented by its TID or NSAP, is included on the target network element access control list. Up to 50 different entries can be included on the access control list.
An OSI-based OS can log in to a remote target NE only if the OSI-based OSI, represented by its NSAP, is included on the target network element access control list.
Important! Specifying a GNE's NSAP is more secure than specifying the TID. Since the TID is provisionable and are generally available, a user attempting unauthorized access to the NE could present a TID that duplicates a TID on the access control list, thereby, bypassing the security provided by the access control list.
Time and date synchronization
Overview
Synchronizing the time and date among all NEs in a network is useful to correlate events reported by different NEs.
The time and date is synchronized:
• Manually using the WaveStar
®
CIT
Administration
→ Set Date and Time command.
• Automatically from another NE via the DCC.
• Automatically by the OS
Provisioning
In a new installation, it is recommended that the time and date be manually provisioned in at least the first Alcatel-Lucent 1665 DMX in each ring. Each subsequent Alcatel-Lucent
1665 DMX that is added to the network tries to learn the current time and date from one of the existing NEs automatically.
After start-up (or any subsequent controller resets), the Alcatel-Lucent 1665 DMX's time and date revert back to the last time and date before the reset. Alcatel-Lucent 1665 DMX waits 5 minutes, in case other NEs are also resetting (for example, as part of a software upgrade of the network), before starting to check with other NEs for the current time and date. If necessary, the Alcatel-Lucent 1665 DMX checks with all remote NEs for the current time and date.
Alcatel-Lucent 1665 DMX allow up to 2 minutes for each remote NE to respond before checking with the next remote NE for the current time and date, and keep checking until a valid current time and date is found.

Time and date synchronization
....................................................................................................................................................................................................................................
Alcatel-Lucent 1665 DMX accepts a provisioned time and date value or any remote NE date later than
00-01-01 as a valid current time and date.
Network time protocol
Network Time Protocol (NTP) assures accurate synchronization of Alcatel-Lucent 1665
DMX with reference to radio and/or atomic clocks located on the Internet.
Considerations
The automatic time and date synchronization is intended to achieve time and date synchronization among compatible NEs with DCC connectivity in a network, but such synchronization can not be guaranteed at start-up for all network configurations or over the course of time.
TL1 command responses and autonomous messages include Alcatel-Lucent 1665 DMX's current time and date. As an alternative to manually provisioning and confirming the current time and date in each Alcatel-Lucent 1665 DMX in a network, OMS, automatically checks the current date and time, periodically or on-demand.

Office alarms interface
....................................................................................................................................................................................................................................
Office alarms interface
Description
The office alarms interface is a set of discrete relays controlling audible and visible office alarms. Relays are provided for the following types of alarm conditions:
• CR (critical)
• MJ (major)
• MN (minor)
If desired, critical and major alarm outputs can be wired so that either, neither, or both of the outputs control the major office alarm.
Steady state current
The steady state current for office alarm connections must not exceed 1.0 Amp at 60 Volts or 1.8 Amps at 30 Volts. The maximum transient currents (20 msec duration) during initial contact closure must not exceed 9 Amps at 60 Volts or 18 Amps at 30 Volts.
Provisionable alarm delay and alarm clear delay
Alcatel-Lucent 1665 DMX provides provisionable incoming signal alarm delay and alarm clear delay. The office alarms are not activated unless an incoming signal condition of greater duration than the alarm delay occurs. When a failure clears, a provisionable alarm clear delay prevents premature clearing of the alarm.
Multiple alarms
When multiple alarm conditions occur, the highest-level office alarm (audible and visible) is activated. When the highest-level alarm condition clears, the office alarm "bumps down" to the next highest level alarm condition.
If enabled, the Remote NE Status feature includes alarms at other NEs in the same alarm group as the local NE to determine when to activate the local office alarm and the appropriate alarm level.
Alarm cut-off
The audible office alarms are silenced through activation of the alarm cut-off (ACO) function. Visible alarms are not extinguished by the ACO function.
If the ACO function has been activated to silence the active audible alarm and a "bump down" occurs, the audible alarm remains silent (that is, the lower level visible alarm is activated, but the corresponding audible alarm is not reactivated). If another alarming condition occurs while the ACO is active, the highest level audible alarm is activated

even if the new condition is a lower level. For example, if a major (MJ) alarm was active and silenced using the ACO function and a minor (MN) alarming condition occurs, the
MJ audible alarm will sound.
Remote NE status
Overview
If enabled, the Remote NE Status feature reflects the summary alarm/status level for both the local and remote NEs in the same alarm group as the local NE with the following local indications.
Office alarms
The local office visual alarm always shows the highest alarm level. The local office audible alarm is activated in response to each new alarm occurrence among the local and remote NEs. Thus alerting on-site craft of problems in the network with an indication of the severity.
SYSCTL faceplate LEDs
The CR, MJ, or MN LED on the local SYSCTL circuit pack faceplate shows the highest alarm level among the local and remote NEs. The FE LED on the local SYSCTL circuit pack faceplate is illuminated if any remote NE has an active alarm, abnormal status
(indicated by the ABN LED), or "activity" status condition, thus identifying the local NE to query further. (Although not dependent on the Remote NE Status feature, the Near-End
LED on the local SYSCTL circuit pack faceplate is only illuminated if the local NE itself has an active alarm, abnormal status, or "activity" status condition.)
Remote NE status and alarm/status retrieval
The local NE can retrieve the highest alarm/status level of each NE in a network with an active alarm, abnormal status, or "activity" status condition, thus identifying the remote
NE to further query.
Determination of the highest alarm/status level of each NE includes the alarm/status level of active miscellaneous discrete alarm/status inputs.
The Remote NE Status feature can be used to expedite maintenance activities for NEs that report TL1 autonomous alarm/status messages to a maintenance OS at an operations center.
The Remote NE Status feature may be enabled or disabled. By default, the Remote NE
Status feature is disabled.

Alarm group
By default, all Alcatel-Lucent 1665 DMX systems are assigned to alarm group 255. This is typically sufficient for small networks of up to 50 nodes. All NEs with DCC connectivity that have the same alarm group number are members of the same alarm group. All alarm group members share summary alarm/status information with each other but not with NEs in different alarm groups. To take advantage of the remote activation of local office alarms, in particular, at least one member of the alarm group should be located in a central office.
In large networks, with IS-IS Level 2 Routing and multiple Level 1 areas, each alarm group must be confined to within a single Level 1 area only. For example, a network with three different Level 1 areas would require a minimum of three alarm groups, that is, one alarm group for each Level 1 area. If desired, multiple alarm groups can be defined within a Level 1 area, also. The maximum number of NEs in an alarm group is limited by the maximum number of nodes in a Level 1 area.
Alarm gateway NE (AGNE)
By default, no NE is enabled as an AGNE. Even if the default alarm group number for all
NEs is used, at least one NE in each alarm group must be enabled as an AGNE. Any NE in an alarm group can be enabled as an AGNE, for example, an AGNE does not need to be located in a central office, in fact, it is recommended that an AGNE should not also be a TL1 TCP/IP GNE or IS-IS Level 2 Router.
A second NE in each alarm group may be enabled as a backup AGNE, if required. It is recommended that the maximum number of AGNEs per alarm group be limited to at most two to assure good performance.
Instead of having every NE exchange alarm/status information with every other NE in the same alarm group directly, only the AGNE receives alarm/status information from every
NE directly, and the AGNE distributes the accumulated alarm/status information for all the NEs to every NE in the alarm group.

Provisioning sequence
If there is no AGNE, each NE in an alarm group reports an
AGNE Communications Failure alarm; therefore, the following provisioning sequence is recommended:
1. Provision one or two (at most) NEs as the AGNE
• Enable the Remote NE Status parameter
• Enable the network element as an Alarm Gateway
• Provision the alarm group number, if different than the default.
2. Provision the other NEs in the same alarm group
• Enable the Remote NE Status parameter
• Provision the alarm group number, if different than the default.

Network size
Overview
There is no inherent limit to the total number of NEs in a SONET transmission network, but there is a limit to the number of nodes that can be part of the same OSI domain, that is, with OSI LAN and/or DCC connectivity for operations communications among the
NEs.
Maximum number of OSI nodes
Alcatel-Lucent 1665 DMX supports a total of 300 OSI associations per TCP and 300 OSI associations for TL1 per Gateway Network Element (GNE). Alcatel-Lucent 1665 DMX can support a total of 250 NEs per Level 1 area.
IS-IS level 2 routing
IS-IS Level 2 Routing involves the assignment of NEs to multiple areas of less than 50 nodes each. Level 2 routers support OSI communications between the NEs in different areas. Both the assignment of NEs to areas and the enabling of NEs as Level 2 routers is accomplished by provisioning.
Directory services
What are directory services?
OS and WaveStar
®
CIT users access remote Alcatel-Lucent 1665 DMX using the remote
Alcatel-Lucent 1665 DMX Target Identifier (TID, name) but remote Alcatel-Lucent 1665
DMX are addressed on the DCC using Network Service Access Point Address (NSAP).
Therefore, a method to provide TID-to-NSAP (name-to-address) and NSAP-to-TID
(address-to-name) translations is necessary. Target Identifier Address Resolution Protocol
(TARP) provides this capability.
For SONET NEs that support TCP/IP and TL1 OS interfaces, TARP is a directory services standard that supports multi-vendor OI compatibility. TARP is specified in
Telcordia
®
GR-253-CORE, SONET Transport Systems: Common Criteria.
TID provisioning
Each NE in a network must be provisioned with a unique TID. The Alcatel-Lucent 1665
DMX's default TID is "LT-DMX". The terms TID and source identifier (SID) are generally used interchangeably.
....................................................................................................................................................................................................................................

Administration
Directory services
....................................................................................................................................................................................................................................
Important! Some other-vendor NEs may require that all TIDs adhere to specific rules, for example, that each TID start with an alphabetic character and/or that each
TID consist of at least 6-to-7 characters.
To be compatible with other products, Alcatel-Lucent 1665 DMX TIDs should not include special characters "%" and "#". Even though Alcatel-Lucent 1665 DMX TID provisioning allows those special characters, T1.245 SONET Directory Services
(SDS) does not support those special characters.
NSAP provisioning
By default, each Alcatel-Lucent 1665 DMX has a unique Network Service Access Point
(NSAP) address, thus no NSAP provisioning is necessary in small networks. If the network size exceeds 250 OSI nodes, NSAP provisioning is required.
TARP provisioning
Although TARP functions automatically without any user provisioning, using standard default values, Alcatel-Lucent 1665 DMX allows provisioning of the following TARP parameters. All TARP parameters are provisionable:
• Lifetime
• Manual Adjacency
• Timers
• Loop Detection Buffer (LDB) Flush Timer
• TARP Data Cache (TDC) Enable/Disable
• TDC TID-NSAP Entries.
It is recommended that the TARP default values always be used.
TARP TID-to-NSAP translations
The three operations that depend on TARP TID-to-NSAP translations are:
1. TL1 OS access
2. WaveStar
®
CIT access
3. Remote (Software) Install Program/Copy Program.
When a TL1 TCP/IP Gateway Network Element (GNE) receives a TL1 login request for a
TL1-RNE, the TL1 login request includes the TL1-RNE's TID. The TL1–GNE relies on
TARP to determine the TL1-RNE's NSAP. The TL1–GNE needs the NSAP to establish an
OSI association with the TL1-RNE. The TL1 login request is forwarded to the TL1-RNE over that OSI association.
The local Alcatel-Lucent 1665 DMX serves as a TL1–GNE and uses TARP as described above for WaveStar
®
CIT access via Alcatel-Lucent 1665 DMX's serial ports or TCP/IP.

performs the TL1–GNE function and uses TARP in a similar manner, also. The local
Alcatel-Lucent 1665 DMX uses TARP as described above to support remote Install
Program/Copy Program.
TARP propagation
The first time a TL1–GNE (or local Alcatel-Lucent 1665 DMX) requires a TARP
TID-to-NSAP translation for each remote NE, the TL1–GNE originates a TARP query.
The TARP query is propagated to all NEs in the same OSI routing area, and if no response is received from within the area, up to two additional TARP queries are propagated throughout the OSI domain. Each NE forwards the TARP queries to each of its neighboring OSI nodes (that is, adjacencies), except the neighbor from which the
TARP query was received.
When the TARP query reaches the remote NE with the requested TID, that remote NE responds to the originating NE with the remote NE's NSAP address. If there is no response to any of the TARP queries for a TID, after the third query times out, an error response (for example,
TL1–GNE unknown TID or
TID not found
) is returned to the originating NE.
TARP NSAP-to-TID translations
When an Alcatel-Lucent 1665 DMX is commanded to perform this translation, it knows the NSAPs of the remote NEs to be included in the responses but relies on TARP to determine the corresponding TIDs.
To ensure that the responses to these commands always include the most up-to-date network information, real-time TARP queries are originated instead of relying on the
TARP Data Cache or TDC (although the TDC is updated, as appropriate, based on the responses to these NSAP-to-TID queries).
Because the NSAPs are known, these TARP queries are addressed directly to each remote
NE (TARP propagation is not necessary). Each remote NE responds to the originating NE with the remote NE's TID.
TARP data cache
In order to reduce the frequency of TARP propagation, and to improve the performance of the affected operations, Alcatel-Lucent 1665 DMX supports a TDC option. By default, the TDC is enabled.
Each Alcatel-Lucent 1665 DMX maintains its own TDC, independently. The TDC consists of TID-NSAP translations. Each Alcatel-Lucent 1665 DMX automatically updates its own TDC based on the responses to previous TARP queries. The TDC may also be updated upon receipt of an unsolicited, automatic notification from another NE in

the same OSI domain of a TID or NSAP change. The TDC has a maximum number of 16 entries; up to 15 entries may be manually entered. A circular buffer is used for the dynamic entries in the TARP Data Cache.
Alcatel-Lucent 1665 DMX checks its TDC to see if it already has a required
TID-to-NSAP translation before originating a TARP query. If a translation is not found in the TDC, the response to that TARP query is used to update the originating
Alcatel-Lucent 1665 DMX's TDC. Alcatel-Lucent 1665 DMX assures that its TDC maintains only one TID-NSAP translation for each unique TID. Alcatel-Lucent 1665
DMX supports TDC sizes of up to 110 TID-NSAP translations. If the TDC is disabled or
Alcatel-Lucent 1665 DMX's system controller is reset, the contents of the TDC are deleted.
TDC accuracy
In the unlikely event that a TDC includes an inaccurate TID-to-NSAP translation,
Alcatel-Lucent 1665 DMX confirms that both the NSAP and TID of the remote
Alcatel-Lucent 1665 DMX are correct before a remote operation proceeds. If there is a mismatch, an error response (for example,
TL1-RNE unknown TID
,
Inconsistent
TID
, or
Association Setup Failure
) is returned to the originating NE.
To correct such a situation, delete the subject TID (L4tdctid) from the TDC, then re-request the remote operation for the subject TID. The subsequent TARP query results in an accurate TID-to-NSAP translation, and the TDC is updated accordingly. A broader solution is to disable and re-enable the TDC in which case all TDC entries are deleted.
Security
Capabilities
Alcatel-Lucent 1665 DMX provides security capabilities to protect against unauthorized access to the system.
User types
Five types of users (with tiered restriction levels) are allowed access to the system with a valid user ID and password:
• An Administrator user has access to all the security functional capabilities. Only the privileged and administrator users have access to the security and access functions.
These functions include assigning/changing user ID/passwords for other users, setting target identifier (TID) names, resetting the system, and system initialization functions.
• Privileged users can execute all commands

A privileged user has access to all the system functional capabilities. Only the privileged and administrator users have access to the security and access functions.
These functions include assigning/changing user ID/passwords for other users, setting target identifier (TID) names, resetting the system, and system initialization functions.
A privileged user can terminate the login session of other individual users (including other privileged users) or terminate all login sessions of non-privileged users.
• General users have access to all the system functional capabilities except security, access, system initialization and software installation functions.
• Maintenance users can only execute commands that access the system, extract reports and execute maintenance functions through a specific set of commands. No privileged commands may be executed by maintenance users.
• Reports-only users can only execute commands that retrieve reports from the system.
Security can be set to a "lockout" state, which blocks non-privileged users from logging in to the system.
System initialization
When the system is first initialized, three privileged default user IDs and passwords are provided. Up to 147 user IDs and passwords can be added, deleted, and/or changed by any of the privileged users. Timeouts are provisionable on a per-user basis.
User IDs and passwords
The WaveStar
®
CIT always asks the user for the NE user ID and password with the first
NE connection. The user ID and password can be saved for subsequent connections, but the user ID and password can not be saved past the current WaveStar
®
CIT session. User
ID and password parameters must be administered on a per-NE basis. You may have a different user ID and/or password on one NE than you have on other NEs.
Each time the number of invalid sequential login attempts reach or exceed the provisionable user ID lockout threshold, the network element reports a Security Alert alarm.
Inactivity timeout period
The inactivity timeout period is the number of minutes after which a user with an inactive session is logged out. A provisionable inactivity timeout period is supported on a per-user basis.

Password aging
The password aging interval is the number of days allowed before a user's password expires. When a user's password expires, the user is prompted to select a new password prior to login. The values for the password aging interval are zero (0) or a range from 7 to
999 days. A value of zero (0) disables password aging. The default value is 0. Password aging does not apply to privileged users' passwords.

CIT default user IDs and passwords
Two default Privileged user IDs and passwords are initially installed in the WaveStar

CIT are LUC01 and LUC02 (LUC-zero-one, and LUC-zero-two). Their associated passwords are LUC+01, LUC+02, (LUC-plus sign-zero-one, LUC-plus sign-zero-two), respectively.
NE default user IDs and passwords
Three default Privileged user IDs and passwords are initially installed in the NE is
LUC01, LUC02, or LUC03 (LUC-zero-one, LUC-zero-two, and LUC-zero-three). The default password is DMX2.5G10G.
RADIUS authentication for user logins
When the network element is provisioned to use Remote Authentication Dial In User
Service (RADIUS) authentication for user logins, any user login triggers the network element to query the designated RADIUS server(s) and act on the response.
Access-Accept
The Access-Accept packet informs the RADIUS client that the user’s login attempt is authenticated and authorized. No further local validation is required.
The Access-Accept message supports a vendor-specific attribute for the purposes of identifying the user access privilege.
The vendor-specific attribute is provisioned on the RADIUS server; it is not provisioned on the NE. Whomever is responsible for provisioning the RADIUS server to needs to know the vendor-specific attribute information for Alcatel-Lucent 1665 DMX.
The integer values of the fields of this attribute are:
• Type: 26
• Length: 9
• Vendor-ID: 7483 (The SMI Network Management Private Enterprise Code of
Alcatel-Lucent)
• Vendor-type: 100 (User Access Privilege)
• Vendor-length: 6

• Vendor-value: select from one of the following integers
– 1 PRIVILEGED
– 2 ADMINISTRATION
– 3 GENERAL
– 4 MAINTENTENANCE
– 5 REPORTS-ONLY
If the above defined Vendor-Specific attribute is not included in an Access-Accept packet, the user access privilege is treated as REPORTS-ONLY.
Access-Reject
The Access-Reject packet informs the RADIUS client that the user’s login attempt is rejected due to invalid username and/or password.
If no response is returned within approximately 5 seconds to the RADIUS client, the
Access-Request packet is re-sent one time. If the retry to the primary RADIUS server fails, the RADIUS client sends the Access-Request packet to the secondary RADIUS server (if provisioned).
If no response is received after retries to the primary and secondary RADIUS servers, the network element validates the user login using the local database.
Access-Request
The network element (RADIUS client) sends a RADIUS Access-Request packet to the
RADIUS server via the IP network. The Access-Request packet contains the User-Name,
User-Password, and the network element IP address. The User-Password is hidden
(encrypted).
When the RADIUS server receives the Access-Request packet, it validates the sending
RADIUS client. A RADIUS client and server must have a provisioned shared secret (the password shared between the RADIUS client and server). If the shared secret is not valid, the Access-Request packet is silently discarded without sending a response. If the shared secret is valid, the RADIUS server searches the user database. If the username is found and the password is correct, the RADIUS server returns an Access-Accept packet to the
RADIUS client.
MAC address locking
Alcatel-Lucent 1665 DMX allows MAC locking on the LNW170. MAC locking prevents unauthorized users from gaining access to the network through an Ethernet port, thereby providing a level of security against intrusion attempts. MAC locking restricts access to a bridged Ethernet network by requiring that the source address of traffic entering a locked port be registered with that port. Any number of ports, LANs, VCG, or link aggregation groups (LAGs) can be locked. Alcatel-Lucent 1665 DMX permits registering of multiple addresses with a single entity.

– The provisioned maximum password length is provisionable to be equal to or greater than the minimum password length; the maximum is 20 characters.
• If the provisioned value of the maximum password length is less that or equal to 10 characters, the following password composition rules apply:
– Passwords must contain at least one alphabetic character and at least three non-alphabetic characters (numeric and the special characters)
– At least one of the non-alphabetic characters must be a numeric character and at least one must be one of the special characters.
• If the provisioned value of the maximum password length is greater than 10 characters, the following password composition rules apply:
– Passwords must contain a mix of upper-case alphabetic characters, lower-case alphabetic characters, numeric characters, and special characters, including at least two of each type.
– Passwords cannot contain consecutive identical characters.
– A password cannot contain the user login.
• When passwords are changed, the old and new passwords must be different in at least three-character positions. The original password, or a significant substring of it, must not be part of the new password.

User-settable miscellaneous discrete interface
Overview
This section describes the miscellaneous discrete environmental alarm/status input points and (external) control output points.
Description
The user-settable miscellaneous discrete interface allows users to monitor and control equipment collocated with Alcatel-Lucent 1665 DMX through a set of discrete input and output points. There are 19 miscellaneous discrete inputs to monitor environmental conditions such as open doors or high temperature, and 4 miscellaneous discrete outputs to control equipment such as fans and generators.
Local miscellaneous discrete input points are included in the determination of the summary alarm/status level for each NE. But even if the Remote NE Status feature is enabled, the alarm/status of individual miscellaneous discrete inputs/outputs is not exchanged among NEs.

If a miscellaneous discrete input point is provisioned as an alarm (minor, major, or critical), TL1 autonomous message REPT ALARM EVT is used to report the alarm occurrence. This identifies the remote NE to further query.
If a miscellaneous discrete input point is provisioned as not alarmed (that is, status), TL1 autonomous message REPT EVT CON is used to report the condition. This identifies the need to retrieve any active miscellaneous discrete status conditions.
Miscellaneous discrete input description
The description to be associated with each miscellaneous discrete input alarm or status point may be provisioned. The provisioned description appears as the almmsg or conddescr parameter value in applicable TL1 messages. The default description for each miscellaneous discrete input point is environment1
, environment2
, and so forth.
Note: Miscellaneous discrete Input Point 15 is reserved for fan failure.
Miscellaneous discrete output description
The description to be associated with each miscellaneous discrete output control point may be provisioned. The default description for each miscellaneous discrete output point is control1
, control2
, and so forth. Control points for miscellaneous discrete outputs may be operated and then released.
Fan failure
Miscellaneous Discrete #15 is reserved for fan failure. The possible alarm levels are CR,
MJ, MN, with MJ being the default.

Overview
Purpose
This section summarizes basic system planning and engineering information to plan procurement and deployment of Alcatel-Lucent 1665 Data Multiplexer (Alcatel-Lucent
1665 DMX).
There are a number of considerations that should be kept in mind when planning the
Alcatel-Lucent 1665 DMX's role in the network. Projected customer requirements will determine initial capacity needed, as well as evolution to higher capacities. The advanced networking capabilities of the Alcatel-Lucent 1665 DMX offer many economic and planning benefits, and certain guidelines should be followed to maximize these benefits.
Physical installation considerations will be guided by the installation location (central office, uncontrolled, or customer locations). Initial network configuration will determine synchronization requirements. Synchronization should be planned on a network basis considering items like topology, reliability, internetwork connectivity, and service evolution.

Requirements
The SYSCTL LNW2 circuit pack must be located in the control CTL slot.
At least one Main (M1/M2) circuit pack is always required in Alcatel-Lucent 1665 DMX to provide timing for the shelf. M1 and M2 can be equipped with any of the following types of packs:
• The Main Switch Pack (LNW80) must be located in the main M1 and M2 slots for protected service.
• OC-12 OLIU LNW48, LNW50, LNW203 must be located in the main M1 and M2 slots for protected service.
• OC-48 OLIUs LNW27, LNW29, LNW76, LNW82, LNW202, LNW504 must be located in the main M1 and M2 slots for protected service.
• OC-192 OLIUs LNW56, LNW58, LNW59, and LNW502 must be located in the main
M1 and M2 slots for protected service
• The VLF LNW59, LNW82, or LNW504 OLIU circuit packs are required in the main
M1 and M2 slots when LNW55, LNW62, LNW64, LNW603 OLIU circuit packs are installed in the function/growth slots.
The tributary slots (A1, A2, B1, B2, C1, C2, D1, D2, G1, G2) can be occupied by a variety of service interface packs. Refer to
“Tributary interface circuit packs” (p. 2-4)
for a comprehensive list of the tributary circuit packs. The following rules apply to the tributary packs.
• The LNW37 and LNW45 (OC-3), LNW49 (OC-12), and LNW31, LNW55, LNW62,
LNW402 (OC-48) packs may be used interchangeably.
• Except for unprotected applications, the same circuit pack type is required in the service and protection slots of a function/growth group (for example, D1 and D2) and growth slots G1 and G2. When the main slots are equipped with VLF circuit packs,
Alcatel-Lucent 1665 DMX supports true 0x1 configurations. Slots 1 and 2 of a group can be equipped with the same circuit pack type or with different circuit pack types
(certain restrictions apply). When a companion slot is unoccupied, an apparatus blank must be installed in the empty slot regardless of the software release or the circuit pack types installed in the shelf.
• The electrical interface circuit packs (LNW7, LNW8, LNW801, LNW16, LNW18,
LNW19B, and LNW20) must be located in function unit slots A - D. Growth slots do not support electrical interface circuit packs. However, when the LNW20 circuit pack is installed in the Growth slots, portless DS3 port operation is supported. LNW7 circuit packs are not supported in shelves equipped with VLF circuit packs.
• When non-VLF Main circuit packs are used, the Ethernet circuit packs (LNW63,
LNW87, LNW170) must be located in slot 1 of a function unit (including growth slots). The other slot must contain a 177D apparatus blank or an LNW98 detectable blank circuit pack. When VLF Main circuit packs are used, Ethernet circuit packs can be used in both slots of a group. Certain restrictions apply. See
(VLF) engineering rules” (p. 6-15) .

Medium and large fabric engineering rules
Overview
This section describes the functionality and limitations resulting from the use of the medium and large switch fabrics in high-speed circuit packs. Use this section to help plan the use of circuit packs in Main slots of the Alcatel-Lucent 1665 DMX shelf. Because of the smaller switch fabric in these circuit packs, they are less costly; however, the smaller switch fabric (12 STS-1) can not handle the same volume of cross-connections as the large switch fabric (48 STS-1). Therefore, circuit packs with medium-size switch fabrics have cross-connection restrictions.

A shelf equipped with medium switch fabric main circuit packs has the following capabilities:
• Function Groups A, B, C, and D are general purpose slots and support all low-speed circuit packs. Some low-speed packs supported in Function Group slots also require the installation of VLF Main circuit packs in the shelf.
• Function Group G is referred to as the growth slot. The growth slot supports only optical, low-speed circuit packs, these includes all of the OC-3/12/48/192 port cards as well as the LNW63, LNW73/73C, LNW74, LNW87, and LNW170 Ethernet cards.
(Some low-speed packs supported in Growth slots also require the installation of VLF
Main circuit packs in the shelf and are therefore not supported by the medium fabric main packs.)
When the LNW74 is installed in slot G1 or G2, only optical PTMs can be used.
• Function groups A, B, and C have an STS add/drop capacity of 24 STS-1s. This is a hardware-based restriction imposed by the use of the medium-sized STS switch fabric in the MAIN cards.
• Function Groups A, B, and C support up to 24 ported TMUX DS3 or EC1 ports.
• Function Group D supports up to 48 ported TMUX DS3 or EC1 ports.
• Function Group G does not support TMUX circuit packs.

• Function Group G is referred to as the growth slot. The growth slot supports optical, low-speed circuit packs. These include all of the OC-3/12/48 packs, the LNW705 and
LNW785, as well as the LNW63, LNW73/73C, LNW74, LNW87, and LNW170
Ethernet. (Some low-speed packs supported in Growth slots also require the installation of VLF Main circuit packs in the shelf, and are therefore not supported by the large fabric main packs.) Growth slots can also house LNW20 TransMUX packs functioning in portless mode.
When the LNW74 is installed in slot G1 or G2, only optical PTMs can be used.
• All function groups have an STS add/drop capacity of 48 STS-1s.
• Function Groups A, B, C, and D support up to 48 ported TMUX DS3 or EC1 ports, 24 portless TMUX DS3 ports
• Function Group G supports up to 24 portless TMUX DS3 ports

Engineering restrictions at the circuit pack level
This section describes engineering/cross-connection restrictions when using medium switch fabric circuit packs.
OC-12 medium fabric
The LNW48, LNW50, and LNW203 employ a 12 STS-1/VT1.5 switch fabric with the following capacity:
• 784x784 VT matrix
• 216x216 STS matrix
Function Groups A, B, and C support 24 STS-1 add/drop capacity
• Additional pass-through traffic is supported
• Any circuit pack with a capacity of 48 STS-1s is limited to 24 STS-1s (ex. 24 DS-3 add/drop capacity with LNW19B)
• 1 virtual concatenation group (VCG) pair is accessible to GbE circuit packs
Function Groups D and G support 48 STS-1 add/drop capacity
• Full add/drop capacity to circuit packs capable of 48 STS-1s
OC-48/192 large fabric
The LNW27, LNW29, LNW56, LNW58, LNW76, LNW80, LNW202, and LNW502 circuit packs employ a large 48 STS-1/VT1.5 switch fabric with the following capacity:
• 2688x2688 VT matrix
• 432x432 STS matrix (for OC-48); 720x720 STS matrix (for OC-192)
Function Groups A, B, C, D, and G support 48 STS-1 add/drop capacity
• Full add/drop capacity to circuit packs capable of 48 STS-1s
• Two VCG pairs are accessible to GbE circuit packs
Source/destination engineering rules
Due to hardware limitations in medium switch fabric Mains, cross-connections may be denied even though the capacity of the cross-connect fabric has not been exceeded.
In addition to the position of the shelf, source/destination demarcation is also determined by the STS number. The lower STS number is the source and the higher STS number is the destination.

Once a cross-connect utilizing a VT1.5 within an STS-1 is established, no part of that
STS-1 can be used in a cross-connect to a slot/group on the other side of the shelf. For example, if a VT1.5 from an STS-1 entering the shelf at Function Group B1 (FNB1) was cross-connected to FNA1, another VT1.5 in that same STS-1 could not be cross connected to FNC, FND, or FNG.
Cross-connections made with the LNW7 circuit packs are exceptions to this rule. This pack is always the cross-connect destination. Hairpin cross-connections between these packs are not allowed.
Intra-port hairpins are supported by Alcatel-Lucent 1665 DMX. Yet when an
Alcatel-Lucent 1665 DMX is equipped with medium fabric mains, intra-port hairpins are not allowed.
Very large fabric (VLF) engineering rules
Overview
This section describes the functionality and limitations relating to circuit pack/slot equipage and electrical/optical port availability when the VLF Main circuit packs are used. Use this section to help plan the use of circuit packs in the Function and Growth units of a shelf equipped with VLF Mains.
VLF circuit packs
Alcatel-Lucent 1665 DMX can be equipped with LNW59, LNW82, or LNW504 VLF
Main circuit packs. These circuit packs support true 0x1 configurations, in some cases resulting in double the overall port density for a given interface type.
LNW59 pack supports up to two OC-192 interface and provides a total 140G of
Input/Output interfaces. The LNW59 has 180G of usable STS-1 fabric and 30G of usable
VT fabric.
LNW504 pack supports up to 4 OC-192 interfaces or up to 3 OC-192 interfaces and 4
OC-48 interfaces and has integrated STS and VT fabrics. Although mixing of interface rates is supported, OC-48 interfaces are only supported on ports 5–8, and OC-192 interfaces are only supported on ports 1–4. The backplane interfaces can operate at 10
Gb/s, supporting all VLF-compatible low-speed packs. The LNW504 provides a total of
180G of Input/Output interfaces. The LNW504 has 220G of usable STS-1 fabric and 30G of usable VT fabric.

The LNW82 main pack supports 8 PTM-based multi-rate (OC-3, OC-12, OC-48) ports and integrated STS and VT fabrics. The pack supports a maximum of 8 OC-3 interfaces,
8 OC-12 interfaces or 2 OC-48 interfaces. The LNW82 has a 170G non-blocking, STS fabric and a 20G VT fabric. VLF mains can support 10G per slot or 20G per function/growth group. The pack supports up to 10G of VT1.5s.
• Function Groups A, B, C, and D are general purpose slots and support all low-speed circuit packs (except the LNW7).
Function Group G is referred to as the growth slot. The growth slot supports only optical, low-speed circuit packs, these include all of the OC-3/12/48/192 packs, the
LNW705 and LNW785, as well as the LNW63, LNW64, LNW73/73C, LNW74,
LNW87, and LNW170 packs. Growth slots can also house LNW20 TransMUX packs functioning in portless mode.
VLF Mains provide up to 10G add/drop capacity to each low-speed slot in the shelf.
• Function groups D and G have an STS add/drop capacity of 48 STS-1s.
• Function Groups A, B, C, and D support up to 48 ported TMUX DS3 or EC1 ports, 48 portless TMUX DS3 ports
• Function Group G supports up to 48 portless TMUX DS3 ports
However, there are certain restrictions with regard to which packs can reside next to each other in the same Function Unit or Growth slot. This section details these restrictions and provides general guidelines for circuit pack/slot equipage with the VLF Mains.
With VLF circuit pack in the Main slots, all switching and cross-connect functions are centralized on the STS and VT fabrics located on the VLF Main circuit pack. This is in contrast to shelves equipped with non-VLF Main circuit packs, where switching and cross-connection functions are distributed across the Main (high-speed) and tributary
(low-speed) circuit packs/fabrics. When VLF Main circuit packs are used in conjunction with tributary packs that contain their own switch fabrics, the switch fabrics on the tributary circuit packs are automatically disabled.
Tributary circuit packs supported
The VLF Main circuit packs support all circuit packs supported by Alcatel-Lucent 1665
DMX shelf with the exception of the LNW7 28DS1 packs. Customers with VLF Mains requiring DS1 connectivity must employ the LNW8/LNW801 56DS1/E1 pack.
Circuit pack compatibility for unprotected (0x1) configurations
The 0x1 capability allows compatible packs of different types to reside in the same low-speed group. Generally speaking, packs which use the rear-access electrical backplane connectors are not compatible with any other packs; that is, they cannot be installed in adjacent slots within the same group. This includes LNW7, LNW8, LNW801,
LNW16, LNW18, LNW19B, LNW20, and LNW74 (unless both LNW74s are version
S1:2 or later and in FX mode).

Certain circuit pack/slot equipage guidelines are the same whether VLF or non-VLF
Mains are used. The use of electrical ports on the LNW170 are not restricted when these packs are installed in the Growth slots because their electrical interfaces are confined to the faceplate only.
Important! When the LNW74 is installed in the Growth slots, only the optical ports are functional. The electrical interfaces on the LNW74 are backplane only and cannot function in the Growth slot. VLF Mains must be used to support true 0x1 with the
LNW74s.
Important! When the LNW20 is used in the Growth slots, it will only function in portless DS3 mode.
In the following list of compatibility guidelines, "Ethernet" includes Ethernet and SAN packs, "electrical" not modified by "TDM" refers to any pack that uses rear-access backplane connectors, and "TDM electrical" excludes Ethernet and Data packs. Note that
"electrical" does not include Ethernet/Data packs using electrical PTMs.
0x1 circuit pack/slot compatibility guidelines
Listed below are circuit pack combinations that are incompatible for 0x1 configurations:
• TDM electrical pack/any other pack
• Any accepted pack/another TDM electrical pack
• 0x1-compatible Ethernet electrical pack/any other electrical pack
All other packs are compatible with each other for 0x1 configurations:
• OLIU/different OLIU
• OLIU/same OLIU
• non-electrical 0x1-compatible Ethernet pack/non-electrical 0x1-compatible Ethernet pack
• OLIU/0x1-compatible Ethernet pack (whether electrical or not)
• electrical 0x1-compatible Ethernet pack/non-electrical 0x1-compatible Ethernet pack

Ethernet equipage guidelines
If the Main slots are equipped with Very Large Fabric LNW59, LNW82, or LNW504
OLIU circuit packs, the circuit packs in a Function/Growth group may be the same or different circuit pack type depending on the Slot Protection State.
For Ethernet circuit packs except the LNW170, the Slot Protection State parameter is fixed Unprotected. If the Slot Protection State is Protected and a 10/100 Ethernet circuit pack (other than the LNW170) is installed, the system reports an unexpected CP type alarm and service may be impacted.
The following combinations of circuit pack types are supported in Function/Growth Slot
1 and Slot 2 when the Slot Protection State is Unprotected.

Notes:
1.
This includes the LNW63, LNW64, LNW73/73C, LNW87, LNW170, LNW705, LNW785, and all low-speed OLIU circuit packs. The LNW7, LNW8, LNW16, LNW18, LNW19B,
LNW20, , LNW74 (S1:1), and LNW801 are not 0x1 compatible.
2.
The circuit pack Ethernet Mode parameter must be provisioned as FX to support LNW74 circuit packs in slot 1 and slot 2; otherwise, this configuration is incompatible. When pairing the LNW74 with another LNW74, ONLY the 8 SFP ports on each pack are usable, for a total of 16 SFP ports per function group. When mixing an LNW74 with any optical only pack, all
24 ports (16 electrical and 8 SFP ports) on the LNW74 are available.
If an incompatible circuit pack is installed in a Function/Growth slot, the system reports a
CP not allowed - eqpt alarm.
The Slot Protection State parameter can be changed from Protected to Unprotected or from Unprotected to Protected.
XM10G/8 port rules
Client ports
The XM10G/8 LNW705 pack supports up to 8 client ports that are populated with PTMs.
The 8 ports can be a mix of the following signals: 1GE, FC100, FICON, FC200,
FICON_EXP, or OC3/12/48. However, there are equipage restrictions that must be followed. The following table lists the rates that are supported on each port.

Port to tributary assignment
In order to maintain fixed port-tributary allocation, the following rules are used:
• First tributary of any port uses the first STS-1 assigned to that port. This rule implies that tributary allocation segments follows 24xSTS1 boundary. Payload of any client port will be mapped on the carrier starting at 1+24xn STS1 position, where n={0,1,…,7}.
• Each port uses a contiguous set of STS1 tributaries required for transporting service supported by that port.
• If number of tributaries needed to transport the client payload (either number of
SONET/SDH tributaries received at the client port or number of tributaries comprising a VCG associated with data port) exceeds 24 STS1s, the client signal claims the tributaries assigned to the adjacent, higher port number, until all client signal carrying tributaries are mapped to STS-192. For example FC200 provisioned on Port1, that requires 37 STS1 tributaries, occupies tributaries 1-37 within an
STS192 and renders Port2 unusable for any other service (the port provisioning rules enforce this).

Overview
These arrangements meet network equipment-building system (NEBS) central office requirements for bay heat dissipation. If typical arrangements are not used, normal heat flow could be interrupted and adversely affect shelf operation. Fan units must be used to guarantee proper air circulation.
Alcatel-Lucent 1665 DMX can be mounted in frames of both 23-inch and 19-inch widths.
23-inch wide frames available through Alcatel-Lucent include the ED8C800 (for rear mounting) and the ED8C801 (for front mounting).

Bay arrangements
A standard 7-foot bay arrangement may contain up to four Alcatel-Lucent 1665 DMX.
When a bay frame is fully equipped with four Alcatel-Lucent 1665 DMX shelves, a
0.515-inch space must remain open at the bottom of the rack to allow for proper air circulation. Alcatel-Lucent 1665 DMX shelves should be installed from bottom to top.
This arrangement is configured for rear access cabling.
Important! The High-Capacity shelf uses an integral fan unit that comes attached to the Alcatel-Lucent 1665 DMX High-Capacity shelf on the bottom of the shelf. The heat baffle is located at the top of the Alcatel-Lucent 1665 DMX High-Capacity shelf.
The figure below shows a typical bay arrangement using the High-Capacity

Shelves can be added incrementally by local technicians (since all cabling is connectorized) if interbay cabling is initially provided for the bay layout. If shelves are incrementally installed, it is recommended that they be installed from bottom to top to simplify bay mult cabling. However, shelves may be added in any position if proper bay mult cabling is selected.
If a shelf is added above existing non-Alcatel-Lucent 1665 DMX equipment one heat baffle (848862181) must be installed between the shelf and the existing equipment.
For detailed information about network bay frame arrangements and installation instructions, see the Alcatel-Lucent 1665 Data Multiplexer (DMX) Installation Manual,
365-372-304.

Mounting bracket positions
The figure below illustrates typical mounting bracket placements on the Alcatel-Lucent
1665 DMX shelf.
Figure 6-5 Mounting bracket positions on Alcatel-Lucent 1665 DMX shelf
Alcatel-Lucent 1665 DMXtend and Alcatel-Lucent 1665 DMXplore rack mount shelves offer the same mounting bracket as Alcatel-Lucent 1665 DMX. The mounting brackets can be placed differently depending on customer requirements (6, 5, or 8 inches back from the front of the shelf).
Equipment compartment
All doors, covers and faceplates that are part of the Alcatel-Lucent 1665 DMX systems design must be in place when installed in the cabinet to minimize losses in cooling and maximize resistance to electromagnetic interference. Apparatus Blanks (see
Alcatel-Lucent 1665 Data Multiplexer (DMX) Engineering and Ordering Information,
ED8C871-10) are ordered separately from the shelf and must be used where no circuit packs are installed.
Splicing compartment
Cable access ports must be provided in the base of the splicing compartment to permit the entrance of metallic and fiber cables into the equipment. Ports must be sized to allow cables to be placed in accordance with minimum bend radii guidelines, as specified by the cable supplier.

Battery compartment
If a battery compartment is provided, it must be segregated from the electronics compartment. A seal must be provided to prevent gases from seeping into the electronics and splicing compartments. The compartment must be vented to the outside.
Air flow capacity
The fan unit must supply sufficient air volume to cool the Alcatel-Lucent 1665 DMX equipment whether using Alcatel-Lucent 1665 DMX internal fans or cabinet-level cooling equipment. When installing the Alcatel-Lucent 1665 DMX in OSP environments, the internal fan units may be removed if the air flow requirements are satisfactorily met.
The amount of air required is based upon the environmental conditions and the self-heating rates of the electronic equipment. An air mover must be functional whenever circuit packs are in operation including during equipment AC power outages.
For thermal performance requirements, see
“Thermal operating temperature for OSP cabinets” (p. 6-35) .
Air flow inlet/exhaust
Alcatel-Lucent 1665 DMX requires air to enter the bottom of the shelf, flow vertically upward and exhaust at the top (and rear if an integrated baffle is used). This direction of flow must properly cool the circuit packs installed in the shelf.
The fan filter must be removed for all Alcatel-Lucent 1665 DMX shelves in all cabinets
(the heat baffle must also be removed on the Alcatel-Lucent 1665 DMX shelf). If the cabinet fan can guarantee at least 200 LFM (linear feet per minute) through the shelf, then the internal fan is not needed. It is recommended that the fan be removed in these instances, and used as a spare for throughout your network.
Cabling
Alcatel-Lucent offers a full complement of transmission cables and optical jumpers.
Alcatel-Lucent 1665 DMX provides rear access for cables.
For more information regarding cable ordering, see
Chapter 7, “Ordering” . For more
information on required cables and cable arrangements, see
in
Chapter 4, “Product description” .
Cable placement and routing
For cable placement and routing information, see Alcatel-Lucent 1665 Data Multiplexer
(DMX) Installation Manual, 365-372-304. Ensure that cables are routed in accordance with the guidelines provided in the Installation Manuals. Circuit pack cables are routed with half of the total number of cables on each side of the shelf.

Cable rating
Cable must be rated for a minimum temperature of 80ºC.
Connector contacts
All connector contacts that mate to Alcatel-Lucent 1665 DMX equipment should be of similar contact finishes. Alcatel-Lucent recommends the use of gold with a minimum of
30 micro-inches.
OSP cabinets
Overview
Outside plant (OSP) cabinet configurations are available using the OSP hardened Main packs: LNW202 (OC-48), LNW48/LNW50/LNW203 (OC-12), LNW80, LNW82
(OC-3/OC-12/OC-48) OLIUs. Many of the low-speed (tributary) packs supported by
Alcatel-Lucent 1665 DMX are OSP hardened.
Air filter in OSP environment
The OSP environment may cause false clogged filter alarms. When the shelf is installed in an outside plant cabinet, the cooling air filter must be removed. The filter is not needed when operating in an OSP. This measure will improve air flow and thus enhance cooling performance and equipment life. See the Alcatel-Lucent 1665 Data Multiplexer (DMX)
User Operations Guide, 365-372-301 or Alcatel-Lucent 1665 Data Multiplexer (DMX)
Installation Manual, 365-372-304 for instructions to suppress the clogged filter alarm.
Suppression of the clogged air filter alarm is required when installing the shelf in an OSP.
Additional information
Detailed information regarding the installation of all Alcatel-Lucent 1665 DMX products in OSP applications can be found in
Chapter 10, “Technical specifications” . For more
information regarding the OSP capabilities of low-speed packs, see
Chapter 4, “Product description” .
Cabinet requirements
Alcatel-Lucent 1665 DMX equipment must be installed in cabinets that have demonstrated compliance in accordance with GR-487 and all other specifications as required by this document. A cabinet that does not meet the requirements of this specification will negatively affect the performance, reduce service life, and threaten service continuity of any Alcatel-Lucent 1665 DMX system.

High temperature alarm
A temperature sensor must be located in the electrical equipment compartment to provide a high temperature alarm when an internal cabinet temperature of 65ºC is reached. The air temperature must be measured at the inlet of the upper-most Alcatel-Lucent 1665 DMX shelf.
Power requirements
Overview
The following information describes the general requirements for electrical power supplied for Alcatel-Lucent 1665 DMX. It does not describe specific current or voltage requirements related to the power consumption of Alcatel-Lucent 1665 DMX. The power consumption of the 1665 products is dependent on the circuit packs installed and their operating state. These variables must be taken into account when sizing the power system.
For specific voltage and current information see
“Power specifications” (p. 10-136)
in
Chapter 10, “Technical specifications” .
Power quality
Alcatel-Lucent 1665 DMX products require a reliable low noise power source in accordance with GR-9478. This is usually accomplished by float charging batteries at the input to the Alcatel-Lucent 1665 DMX shelves. Batteries are installed to provide back up power in the event of AC power outages. When deployed in a float charge configuration they also provide filtering of AC power line drop outs and noise generated by equipment in the cabinet/bay. In all cases power must be configured to avoid dropping below or exceeding the voltage limits listed in the tables above.
Electrical noise
Care must be taken to insure that electrical noise generated by the power system, fans, or other equipment does not interfere with the operation of the Alcatel-Lucent 1665 DMX products. Electrical noise on the −48 volt power lines at the shelf must not exceed the voice frequency and wide-band noise limits in accordance with GR-947.
Interruptions
Momentary AC power line interruptions are accommodated by the batteries on float charge.

Inrush current
While there is no requirement to limit the rate of power application to the Alcatel-Lucent
1665 DMX shelves, the voltage at the shelf must remain within the specified limits at all times.
Battery backup
In all cases, battery backup power must be configured to avoid dropping below the voltage limits listed in
“Power specifications” (p. 10-136) . The preferred method of
battery backup is a float charge configuration. Alternatively, a separate battery and charger system can be used utilizing a diode "OR" configuration. Systems employing transfer switches are not recommended unless sufficient capacitance is installed to carry the system over through the transfer period.
Grounding and bonding
Grounding must meet the appropriate Telcordia
®
, UL, and NEC requirements for outside plant and customer premises applications. The Alcatel-Lucent 1665 DMX shelves require a single common ground reference. The Alcatel-Lucent 1665 DMX shelf frame must be bonded to an earth ground within the cabinet/bay. Alcatel-Lucent 1665 DMX shelf mounting screws should be used to provide a low impedance multipoint electrical connection through the mounting structure to earth ground. A frame ground wire located on the shelf must be connected to the ground.
I/O protection
The DS1/E1 and DS3/EC-1 interfaces (traffic ports) or other metallic telecommunications interfaces must not leave the cabinet/bay unless connected to telecommunications devices providing primary and secondary protection, as per GR-1089 and UL-60950 (UL 60950/
CAN/CSA- 22.2 NO. 60950-00 Safety of Information Technology Equipment, December,
2000).
The Alcatel-Lucent 1665 DMX DS1/E1, DS3/EC-1, and Ethernet ports are tested according to the following note.
WARNING: The intra-building port(s) of the equipment or subassembly is suitable for connection to intrabuilding or unexposed wiring or cabling only. The intra-building port(s) of the equipment or subassembly MUST NOT be metallically connected to interfaces which connect to the OSP or its wiring. These interfaces are designed for use as intra-building interfaces only (Type 2 or Type 4 ports as described in GR-1089-CORE,
Issue 5) and require isolation from the exposed OSP cabling. The addition of Primary
Protectors is not sufficient protection in order to connect these interfaces metallically to
OSP wiring.

Environmental considerations
Overview
Alcatel-Lucent 1665 DMX meets NEBS Level 3 standards for use in central office environments as specified in GR-63-CORE and GR-1089-CORE. Alcatel-Lucent 1665
DMX also meets standards for uncontrolled environments as specified in GR-63-CORE and GR-499-CORE. For detailed specifications, see
Chapter 10, “Technical specifications” .
Vibration
The cabinet/bay must be resistant to continuous low level vibrations from sources including train and vehicular traffic, rotating machinery, construction activities, etc.
Physical tests must be performed to assure the cabinet/bay does not amplify vibrations from these sources such that the vibration levels transmitted to the equipment do not exceed design limits. Tests must be performed in accordance with GR-487 and GR-63 to verify the performance of the cabinet/bay and equipment during vibratory test conditions.
Thermal operating temperature for OSP cabinets
Inlet air to the Alcatel-Lucent 1665 DMX equipment must be controlled within the range of −40ºC to +65ºC. Ambient air from outside the cabinet cannot be introduced into the electronics compartment or used in any way to directly cool the Alcatel-Lucent 1665
DMX equipment within the cabinet.
Heat exchange systems for cabinet must be sized so that maximum inlet temperature will not exceed 65ºC even when the shelf is equipped in such a way that it approaches the maximum current drains detailed in
“Current drains” (p. 10-136) . Also, the cabinet must
be sized to ensure that inlet temperature does not exceed 65ºC given both severe outside ambient temperature and solar heating relative to the conditions of the region where the shelf is deployed.
The supplier must supply performance data upon request for cabinets cooled by compact heat exchangers or any other method. This information may include the appropriate factor of safety, or excess capacity, accounting for normal fouling of the heat exchanger core.
During operation, the time rate of change of the internal air temperature must not exceed
30ºC/hr as the result of solar heating and radiation cooling of the enclosure, and power cycling the equipment.

OSP cabinet condensation
The relative humidity of the internal air of an OSP cabinet must be maintained in accordance with GR-63. This applies even when the equipment within the cabinet is in an unpowered condition, e.g., during installation of equipment. During such times a source of heat, or desiccant packs, must be provided for maintaining the necessary relative humidity level.
Test verification and qualification
Site requirements
Principal requirements for Alcatel-Lucent 1665 DMX equipment are as follows:
• GR-63, covering physical requirements (earthquake resistance, thermal shock, fire, etc.)
• GR-1089 covering electrical requirements (electromagnetic interference, electrostatic discharge, grounding, etc.)
• CSA-C22.2, No. 60950-00, UL609503 Safety of information technology equipment.
System thermal performance verification
For the fully equipped cabinet/bay configuration, a functional test of the Alcatel-Lucent
1665 DMX shelf must be performed with all systems powered at their appropriate levels for typical service applications that approach the maximum current drains detailed in
“Current drains” (p. 10-136) . The OSP cabinet surfaces must be respectively heated at the
appropriate maximum solar radiation levels. Absorbed solar heating must be estimated using the formulations and methods in accordance with GR-487 and the ASHRAE handbook.
During this testing measure, record, and provide upon request:
• Power level into the cabinet/bay in amperes
• Air Velocities in the airflow channels formed by the circuit packs in linear ft/min.
• Air temperature entering and exhausted from the Alcatel-Lucent 1665 DMX shelf
(ºC). Three K or T type thermocouples must be added at the inlet and exhaust of all circuit pack slots. Take the average of the three thermocouples for each circuit pack slot for both inlet and exhaust and record (Tinlet_avg, Texhaust_avg, TC type, and slot number).
• Ambient temperature (temperature outside the cabinet/bay and measured in ºC).
• Solar heating loads on respective cabinet/bay surfaces (ºC).

Overview
Purpose
This section provides cross-connection information for Alcatel-Lucent 1665 DMX. For cross-connect provisioning information, see
Chapter 5, “Operations, administration, maintenance, and provisioning” .
Contents
Assignment of VT bandwidth on OC-n high-speed interfaces
Cross-connection types
Overview
Alcatel-Lucent 1665 DMX has cross-connect capabilities offering users flexibility in directing traffic flow through systems to support a wide variety of customer applications using one-way and multi-point (data specific) cross-connections.
Making cross-connections
Cross-connections are made by specifying the SONET rate (VT1.5 or STS-n), the end point addresses (AIDs), and the cross-connection type (for example, 1WAY). Each single cross-connection command establishes a 1-way cross-connection.
Atomic cross-connections
Beginning in Release 6.0, Alcatel-Lucent 1665 DMX employs atomic cross-connections for all cross-connect provisioning. Atomic cross-connections are one-way cross-connections between logical ring channels which can be set up and taken down by a single command, and which cannot be broken down into smaller parts. Logical ring channels are the tributaries of a port or port protection group used for transmission in the absence of any line or equipment protection.
Each portion of a 2way cross-connect is provisioned as 1way cross-connects. This provides increased flexibility in provisioning all cross-connects.

®
CIT, Telcordia
®
Operating Systems (OS), and
INC this change will be transparent. In order to support atomic cross-connections for the first time, customers employing proprietary OS solutions will need to adjust their cross-connection provisioning procedures.
Bidirectional (two-way) cross-connections
A bidirectional connection can be used to send signals between two high-speed ports
(pass-through), two low-speed ports (hairpin or pass-through), and a high-speed and low-speed port (add/drop). Bidirectional cross-connections are supported at the VT1.5,
STS-1, STS-3c, STS-12c STS-48c, and STS-192c rates as a function of the port types
(OC-3/12/48/192-high speed and low-speed).
Unidirectional (one-way) cross-connections
A one-way cross-connection is a unidirectional connection that can be used to send signals between two high-speed ports (pass-through or hairpin, hairpin with the LNW59,
LNW82, or LNW504 only), two low-speed ports (hairpin or pass-through), and a high-speed and low-speed port (add/drop). In add/drop applications, this is used where
VT1.5, STS-1, STS-3(c), STS-12(c), STS-48(c), STS-192(c) signals on high-speed channels are cross-connected to low-speed DS1/E1, DS3, EC-1, OC-3, OC-12, OC-48,
OC-192 10/100/1000BASE-T, 100/1000BASE-X, or FC-DATA ports. Alcatel-Lucent
1665 DMX allows one-way cross-connections in support of DRI, bridge and roll, and true
0x1 unprotected scenarios.
Hairpinning cross-connections
If VLF Main packs are used in “hairpinning” topologies, all cross-connect and switching functions are centralized on the Main pack. Switching within the fabrics on the tributary
(low-speed) OLIUs is disabled and traffic is routed directly to the STS fabric on the
Mains, bypassing any VT fabric on the tributary OLIUs. When non-VLF Main packs are used, tributary (low-speed) traffic is routed into the system and back out without ever being placed on high-speed (OC-12, OC-48 or OC-192) interfaces. In addition, in systems with non-VLF mains, VT cross-connections on the LNW45 and LNW49 are optimized to minimize the VT fabric usage on the main packs. For example, hairpins between different
VTs on an LNW45 or LNW49 are routed using only the VT fabric on the LNW45 or
LNW49, and thus do not consume any VT resources on the main packs.
Alcatel-Lucent 1665 DMX is capable of connecting any input on a circuit pack in a function or growth slot to any output on a circuit pack in the same group (known as inter-fn hairpin). Alcatel-Lucent 1665 DMX also supports intra-port hairpins, by which
Alcatel-Lucent 1665 DMX can hairpin between different tributaries in the same port.
Hairpin cross-connections to 0x1Sn interfaces is also supported. When a VLF Main circuit pack is installed, hairpin cross-connections between unprotected ports on different slots of the same low-speed group are also supported.

....................................................................................................................................................................................................................................
These flexible cross-connect capabilities allow you to use a combination of add/drop and hairpinning of compatible payloads through a variety of interfaces. You can bring traffic in from one remote site and cross-connect it at the VT1.5, STS-1, STS-3c, STS-12c,
STS-48c, or STS-192c level back out to other remote sites without consuming any capacity on the ring/line interface.
Locked cross-connections
In the "locked" mode, Alcatel-Lucent 1665 DMX does not select the best signal from both rotations of a UPSR. Instead, traffic is added and dropped (locked) from one rotation of the ring only (provisionable). The main advantage of locked VT cross-connections is the lack of UPSR switching which results in the ability to reuse time slots around a
UPSR.
Locked, unlocked, and pass-through VT1.5s can be mixed within the same STS-1.
Locked cross-connections are only used in systems that are not equipped with VLF Mains because VLF mains allow unprotected (linear) UPSR cross-connections which allow users to independently provision cross-connections on UPSR tributaries. In systems with non-VLF Mains, once a locked cross-connection is established from a UPSR tributary, the companion tributary cannot be cross-connected.
Linear/unprotected UPSR
Alcatel-Lucent 1665 DMX allows both rotations of a ring to be used. Simultaneous
1WAY cross-connections can be sourced from the 2 associated ring channels in a UPSR application. Simultaneous 1WAY cross-connection sourced from a ring channel, and
1WAY or 1WAYPR destined to the associated ring channel are also supported.
Unswitched cross-connections
Unswitched cross-connections are user-provisionable on a per cross-connection basis and support single- and dual-homed ring on ring topologies. Path protection and internal equipment (switch fabric) protection is disabled in unprotected configurations.
Unswitched cross-connections on Ethernet/Data packs that do not require VCG pairing are supported, but not required.
Multi-point (data-specific) cross-connections
The data specific multi-point cross-connect is a bidirectional cross-connection between two STS-1 Virtual Concatenation Groups (VCGs) on 100/1000BASE-X/T ports to two different ring interfaces. All multi-point cross-connections are done at the STS-1 level
(multi-point cross-connections can also be made at the STS-3c and STS-12c level using the LNW63, LNW64, LNW87. or LNW170 circuit pack. Multi-point cross-connections are used to create packet rings.

Multiple 1WAY UNSWITCHED cross-connections provide unprotected SONET connections to Ethernet circuit packs. Each can be used to form two individual connections. With atomic cross-connections, multipoint cross-connections are provisioned by way of 1WAY UNSWITCHED cross-connects.
Bridged cross-connections
Alcatel-Lucent 1665 DMX supports multicast (1xN) cross-connections where N is limited only by the available cross-connect fabric (for VTs) and the compatible output tributaries.
Bridging of an existing cross-connection consists of adding a one-way cross-connection with the same input tributary as that of an existing cross-connection, resulting in a 1x2 multicast from an input tributary to two output tributaries. Alcatel-Lucent 1665 DMX supports bridging for each of the supported SONET cross-connection rates. You can bridge any existing cross-connection to a second output port without impairing the existing signal. Conversely, either half of a bridged signal can be taken down without impairing the remaining cross-connected signal.
Pipe-mode (adaptive-rate) cross-connections
Pipe mode is a fault monitoring and performance monitoring feature whereby each automatically adapts to changes in the constituent payload structure of a provisioned
STS-n rate cross-connection. Fault and PM are based on the payloads carried within a cross-connection rather than the cross-connection rate. Path protection switching continues to operate at the provisioned cross-connect rate.
DRI cross-connections
DRI cross-connections, used in Dual Ring Interworking applications, are accomplished by means of a one-way, protected drop from a UPSR, a one-way pass-through, and a one-way add to the same UPSR.
Manual cross-connection rates
The following lists the signals that can be cross-connected:
• VT1.5
• STS-1
• STS-3c
• STS-12c

OCH cross-connections
Optical channel (OCH) cross-connections are supported between dense wavelength division multiplexing (DWDM) compatible circuit packs/pluggable transmission modules. The OCH cross-connections are used to inform the network element about manual fiber connections.
OCH cross-connections to/from OCH ports allow the network element to enable alarm reporting and variable optical attenuators. The variable optical attenuators are enabled only when an OCH port is the destination of an OCH cross-connection.
OCH cross-connections to/from OTU2 ports allow the network element to enable alarm reporting and assign the 10G Muxponder internal STS cross-connection fabric to the provisioned client ports.
The following OCH cross-connections are supported:
• DWDM-compatible OC-192 port to/from OCH port
• OTU2 port to/from OCH port
• Remote DWDM-compatible wavelength (remote shelf) to/from OCH port
• OCH port to/from OCH port (pass through)
Important! In order to support pass-through cross-connections, the LNW785 OMD circuit pack requires external optical amplification.
The following circuit packs are DWDM compatible:
• The LNW55 OC3/OC12/OC48 OLIU with OC-48 DWDM-compatible pluggable transmission modules (channels 52–59)
• LNW59 OC-192 OLIU with DWDM-compatible pluggable transmission modules
(channels 52–59)
• The LNW62 4OC-48 OLIU with DWDM-compatible pluggable transmission modules (channels 52–59)
• The LNW82 OC3/OC12/OC48 OLIU with OC-48 DWDM-compatible pluggable transmission modules (channels 52–59)

Message Details, 365-372-306.
Add/drop
All connections from a high-speed interface to a low-speed interface are considered add/drop. An add/drop cross-connection is bidirectional cross-connection between a high speed interface and a low speed interface. Alcatel-Lucent 1665 DMX also supports unidirectional add and drop cross-connections. A signal can also be add/dropped from electrical and Ethernet interfaces.

Unidirectional path switched ring (UPSR)
A UPSR is self-healing ring configuration in which traffic is sent onto both rotations
(both fibers) of the ring in opposite directions. "Path-switched" means that if the working signal fails, the path switches to the protection signal. UPSRs operate in an integrated, single ended fashion- negating the need for complex network-level coordination in the effort to restore traffic.
Bidirectional line switched ring (BLSR)
A 2-fiber is a self-healing ring configuration in which bidirectional traffic travels over the same set of nodes in each direction. Bidirectional switching makes use of redundant
(protection) bandwidth on the bidirectional lines that interconnect the nodes in the ring to provide protection for traffic carried on the working bandwidth. Because the traffic is bidirectional, a single circuit does not necessarily consume bandwidth on every span in the ring. This leaves the spans between other nodes available for additional traffic.
Therefore, with distributed switching patterns, a BLSR can carry more traffic than the same facilities could carry if configured for a unidirectional path-switched ring.
0x1Sn
0x1Sn is not supported when Alcatel-Lucent 1665 DMX is equipped with VLF Main packs (LNW59/LNW82/LNW504). VLF Main packs are required to make true 0x1 cross-connections available.
With 0x1Sn, the OC-n 0x1 provisioning and alarming capability provides the user with a method of provisioning a LS OC-n port in one slot of a slot pair to operate as an unprotected interface. Cross-connections to 0x1Sn ports are provisioned using the ring channel AIDs corresponding to the active side/port. The inactive port, if equipped, always outputs STS1 UNEQ or AIS-P on all tributaries, as a function of the system default idle signal provisioning.
Cross-connections are supported between 0x1Sn ports and all other interface types. For
DHA applications, 1WAYPR and 1WAY cross-connections between a 0x1Sn port to a
UPSR ring channel are required. Cross-connections supported at all rates supported by the LS OC-n port. Multipoint and unswitched cross-connections to 0x1Sn interfaces are not supported.

True 0x1
The VLF Main packs (LNW59/LNW82/LNW504), Alcatel-Lucent 1665 DMX support true 0x1 unprotected circuit packs. That means that any slot can be equipped with any pack (some restrictions apply). Two of the same circuit packs can also populate adjacent slots in the same group (this includes some Ethernet packs). For detailed information on circuit pack/slot equipage restrictions in 0x1 mode, see
“Very large fabric (VLF) engineering rules” (p. 6-15) .
In the case of SONET packs, all ports in a pack must be set to 0x1 application in order for a different pack to be used in the companion slot. If any pair of lines is provisioned for a protected application (1+1, UPSR, BLSR), then both packs in the group must be of the same type.

True 0x1 replaces 0x1Sn functionality when VLF Mains are used. True 0x1 supports all the capabilities 0x1Sn allow, but adds the capability for both slots of a single group to function independently. 0x1Sn is still supported when the shelf is equipped with non-VLF
Mains. True 0x1 is available on the low-speed/tributary packs, and on VLF Main
(M1/M2) interfaces.
When two circuit packs in the same low-speed group are operating in 0x1 mode, all provisioning, reporting and retrieval (of alarms) associated with the pack, ports and tributaries in Slot 1 are independent of the provisioning, reporting and retrieval associated with the pack, ports and tributaries in Slot 2.
When provisioned for 0x1 operation, the affect on service and severity of alarms issued against a pack in Slot 1 of a particular group are independent from the affect on service and the severity of the alarms issued against the pack in Slot 2 of that group.
When Alcatel-Lucent 1665 DMX is equipped with VLF Mains, all 1-way cross-connections supported on an unprotected port/line (including ports/lines on an unprotected pack) in one slot of a group can be supported independently and simultaneously on an unprotected port/line in either slot of a Function or Growth group.
1-waypr cross-connections are not allowed to be sourced from 0x1 interfaces.
True 0x1 enables hairpin cross-connections between channels on packs in different slots of the same group.

Pass-through
A pass-through cross-connection is made between two ring interfaces in the same MAIN or Function Unit group, allowing the signal to be "passed-through" a ring node on the same time slot.
The figure below shows a pass-through cross-connection on the high-speed interface
(OC-12, OC-48, or OC-192).

Low-speed pass-throughs
Alcatel-Lucent 1665 DMX can host multiple rings on the low-speed interfaces of the
Alcatel-Lucent 1665 DMX shelf. This is accomplished by intra-function group, pass-through cross-connections. Alcatel-Lucent 1665 DMX can close a low-speed ring by supporting a cross-connection between a receive port on one circuit pack and a transmit port on another circuit pack in the same function or growth group. All protection switching advantages/capabilities still apply in VT and STS-n Ring Closure applications.
When VLF Main packs are used, all cross-connect switching occurs on the main packs, including low-speed, tributary pass-through cross-connects. This means that the line depicting the pass-through cross-connect in the figure below would have to extend out of the tributary packs, up into the MAIN switch fabric at the top of the figure when VLF
Mains are used.

SONET hairpinning cross-connections
If VLF Main packs are used in “hairpinning” topologies, all cross-connect and switching functions are centralized on the Main pack. Switching within the fabrics on the tributary
(low-speed) OLIUs is disabled and traffic is routed directly to the STS fabric on the
Mains, bypassing any VT fabric on the tributary OLIUs. When VLF Main packs are not used, tributary (low-speed) traffic is routed into the system and back out without ever being placed on high-speed (OC-12, OC-48 or OC-192) interfaces. In addition, in systems with non-VLF mains, VT cross-connections on the LNW45 and LNW49 are optimized to minimize the VT fabric usage on the main packs. For example, hairpins between different
VTs on an LNW45 or LNW49 are routed using only the VT fabric on the LNW45 or
LNW49, and thus do not consume any VT resources on the main packs.

Alcatel-Lucent 1665 DMX is capable of connecting any input on a circuit pack in a function or growth slot to any output in the same group (known as inter-fn hairpin).
Alcatel-Lucent 1665 DMX also supports intra-port hairpins, by which Alcatel-Lucent
1665 DMX can hairpin between different tributaries on the same port.
When VLF Main circuit packs are not installed, hairpin cross-connections to 0x1Sn interfaces are supported. When VLF Main circuit packs are installed, hairpin cross-connections between unprotected ports on different slots of the same low-speed group are supported. Certain restrictions apply, see
“Very large fabric (VLF) engineering rules” (p. 6-15) .
These flexible cross-connect capabilities allow you to use a combination of add/drop and hairpinning of compatible payloads through a variety of interfaces.
Alcatel-Lucent 1665 DMX supports intra-function group, hairpin cross-connections that are cross-connections between different tributaries on different ports within the same function group. Intra-port hairpins are cross-connections between channels hosted by the same physical port of the Alcatel-Lucent 1665 DMX shelf. These intra-port hairpins are only supported on 1+1 protected interfaces.

Portless mode hairpin cross-connections (LNW20)
When operating in portless mode, LNW20 pulls DS1s from channelized DS3 signals that enter Alcatel-Lucent 1665 DMX on a SONET STS-1 interface (on another pack) and converts them to VT mapped STS-1s. This VT-mapped STS-1 is cross-connected at the
VT level in the Main packs (at least one side of the cross-connect is OCn/EC1) to any interface that supports the signal structure today (DS1, channelized DS3, EC1, optical).
For portless functionality, incoming STS-1s must contain a channelized DS3. This STS-1 is cross-connected to the LNW20 and then hairpinned to the STS fabric on the Main pack.
Once the signal is finally converted to a VT1.5 it can be cross-connected to any port that accepts that signal format.

Multi-point (Ethernet only)
The data-specific multi-point cross-connect is a bidirectional cross-connection between two STS-1 Virtual Concatenation Group (VCG) on 100/1000BASE-X/T and ports to two different ring interfaces (UPSR or BLSR with NUT provisioning).
The figure below shows Ethernet Multipoint cross-connection schematic.
Figure 6-10 Ethernet multi-point cross-connection
Ethernet hairpining cross-connections
With Ethernet-to-Ethernet hairpinning, traffic may travel from one Ethernet port on a circuit pack in one set of slots, to another port on a circuit pack in a different set of slots
(from A1 to C1 or A2 to C2, for example). From there, the traffic may be multiplexed with other packet traffic before being switched onto another Ethernet or SONET interface.
In shelves equipped with VLF Mains (LNW59/LNW82/LNW504), hairpins between 0x1 compatible Ethernet packs located in Slot 1 and Slot 2 of the same group are also supported. For detailed information regarding 0x1 circuit pack compatibility, see
“Very large fabric (VLF) engineering rules” (p. 6-15) .

Cross-connections
Allowable cross-connections
....................................................................................................................................................................................................................................
Notes:
1.
Each span of the packet ring has BLSR protection. It is not necessary to "close" the packet ring on a BLSR:
BLSR protection is provided on each span, so spanning tree protection is unnecessary. Capacity on one span of the BLSR can be used for other purposes.
2.
The number of EPL cross-connections on the LNW74 is relative to the slot in which the circuit pack is housed and not the cross-connection rate. 24 VCGs are provisionable in slots A–D. 8 VCGs are provisionable in slot G.
Allowable UPSR add-drop cross-connections
The table below contains a list of UPSR add-drop cross-connections supported by
Alcatel-Lucent 1665 DMX. The cross-connections in the table below are all drop cross-connections.
Note: In UPSR networks with more than 2 nodes, mixing VT and STS add/drops in the same circuit can lead to cases where individual VT defects are not protected at the
STS-1 add/drop node. If you are provisioning VT add/drops, both ends of the add/drop circuit should be VT1.5 cross-connects; mixing VT add/drops and STS-1 add/drops in a multi-node UPSR is not recommended.
Important! With atomic cross-connects, all cross-connections are one-way. For cross-connects not involving UPSR interfaces, the same 1-way cross-connects are supported in the opposite direction to provide two-way connectivity.
The LNW59, LNW82, and LNW504 VLF Main circuit packs make true 0x1 cross-connections and shelf equipage possible. When the VLF Main pack is used, the shelf does not support 0x1Sn cross-connections, or the LNW7 circuit pack. In shelves equipped with VLF Mains, unprotected (linear) UPSR cross-connections are also supported. Unprotected UPSR cross-connections are independent cross-connections to or from the companion UPSR tributaries. For these reasons, the capabilities of the shelf when equipped with the VLF Main packs are listed separately.
In the "To" column of the table below, "TransMUX" includes the LNW18 and LNW20 in both ported and portless mode.

Because VLF Mains are multi-port packs, cross-connections between different ports on the same Main are possible when they are used. All of the cross-connect types listed in the left column are supported between VLF ports.
Important! In systems equipped with non-VLF main, 1way cross-connects FROM
UPSR to E1, TMUX or Ethernet/Data interfaces are not supported. In systems equipped with VLF mains 1way cross-connections from a UPSR are supported to all interfaces.

Assignment of VT bandwidth on OC-n high-speed interfaces
Overview
When using the OC-n OLIU in M1 and M2, for VT add/drop cross-connections, VT hairpin cross-connections, and VT pass through cross-connection, restrictions apply.
Important! The restrictions do not apply to the LNW27, LNW29, LNW76, LNW202,
LNW221-255, LNW502 or the VLF circuit packs.
VT fabric capacity
The VT fabric on the main OC-12/48 OLIU circuit packs (M1 and M2) supports several types of VT cross-connections.
• VT add/drop from/to OC-N OLIUs in the Function Unit and Growth slots.
• VT add/drop from/to DS1 ports.
• VT hairpins.
• VT pass-throughs on the MAIN OC-12/48 OLIUs in M1 and M2.
The total provisionable bidirectional VT cross-connect capacity of 336 VT1.5s is shared among the four types of VT cross-connections.
Important! The "dual tatrib" modes (MONEF and SPLTEF) of VT test access are not possible when the system is equipped with small/medium VT fabric Main OLIUs. For more information see the
“VT1.5 test access matrix” (p. 5-38) .
Source and destination restrictions
The user can not provision a VT1.5 connection whose source STS is the same as the destination STS of another VT1.5 connection. Source and destination are not a function of the src_aid and dest_aid in the ENT-CRS-rr command. Rather source and destination are determined based on the relative STS number. The lower STS number is designated as the source and the higher STS number is designated as the destination based on the following ordering of the slots, main < fna < fnb < fnc < fnd < growth.

Cross-connections
Assignment of VT bandwidth on OC-n high-speed interfaces
....................................................................................................................................................................................................................................
The one exception to this rule is for cross-connections to DS1 ports on the LNW7 packs.
For these connections the OC-N port is always the source and the DS1 port is always the destination. The following example illustrates the restriction. The commands are not syntactically correct. They are intended only to show the aids.
Example
The ENT-CRS-VT1 command uses the following aid format for the src_aid and dest_aid parameters. {group}-{line}-{STS}-{VTG}-{VT1.5}.
Step 1:
Ent-crs-vt1:b-1-1-1-1,a-1-1-1-1 cross-connects a VT1.5 in FN Group A to a VT1.5 in
Function Group B. According to the rule defined above, the lower STS channel (a-1-1) is designated the source and the higher STS channel (b-1-1) is designated the destination.
Step 2:
Ent-crs-vt1:b-1-1-1-2,c-1-1-1-2 cross-connects a VT1.5 in FN Group B to a VT1.5 in
Function Group C.
In the above example, the cross-connection in step 2 (b-1-1-1-1 to c-1-1-1-2) would be denied because the source STS (b-1-1) is the same as the destination STS channel (b-1-1) in the cross-connect established in step 1 (b-1-1-1-1 to a-1-1-1-1).
Pass-through restrictions
If the Main slots are equipped with OC-12 OLIU (LNW48, LNW50, LNW203) circuit packs provisioned to support VT1.5 signals in up to 12 STS-1 signals, VT pass-through cross-connections on the Main circuit packs can in some cases conflict with VT add/drop cross-connections and VT hairpin cross-connections. This restriction, however, cannot be characterized by a set of rules. Requests to establish a VT cross-connection that would result in a conflict between a VT pass-through cross-connection on the main and a VT add/drop or VT hairpin cross-connection are denied.

Network synchronization environment
Overview
Careful consideration should be given to proper design of the SONET network's synchronization environment. Proper synchronization engineering minimizes timing instabilities, maintains quality transmission network performance, and limits network degradation due to unwanted propagation of synchronization network faults. The synchronization features of the Alcatel-Lucent 1665 DMX are designed to complement the existing and future synchronization network and allow it not only to make use of network timing but also to take on an active role in facilitating network synchronization.

Published sources
A number of published sources give generic recommendations on setting up a synchronization network. Alcatel-Lucent 1665 DMX is designed to operate in a network that complies with recommendations stated in GR-253-CORE and the following documents:
• GR-436-CORE, Digital Synchronization Network Plan
• GR-378-CORE, Generic Requirements for Timing Signal Generators (TSG)
• ANSI T1.101, Synchronization Interface Standards for Digital Networks
• GR-1244-CORE, Clocks for the Synchronized Network: Common Generic Criteria.
Recommendations
The following are some key recommendations from the documents listed above. For further detailed explanation, the sources should be consulted directly.
1. A node can only receive the synchronization reference signal from another node that contains a clock of equivalent or superior quality (Stratum level).
2. The facilities with the greatest availability (absence of outages) should be selected for synchronization facilities.
3. Where possible, all primary and secondary synchronization facilities should be diverse, and synchronization facilities with the same cable should be minimized.
4. The total number of nodes in series from the Stratum 1 source should be minimized.
For example, the primary synchronization network would ideally look like a star configuration with the Stratum 1 source at the center. The nodes connected to the star would branch out in decreasing Stratum level from the center.
5. No timing loops may be formed in any combination of primary and secondary facilities.
Stratum 3 timing generator
Alcatel-Lucent 1665 DMX supports a Stratum 3 Timing Generator (TG3) embedded in each high speed (MAIN) Main Switch pack (LNW80), OC-12, OC-48, and OC-192 optical interface circuit pack. The TG3 operates with an internal oscillator of ±4.6 ppm long-term accuracy in the free running mode, while in holdover the accuracy is ±.37 ppm over the full −40ºC to +65ºC temperature range. The TG3 should be used according to the recommendations in the documents referenced previously.

Synchronization features
Overview
Synchronization is an important part of all SONET products. Alcatel-Lucent 1665 DMX is designed for high performance and reliable synchronization and can be used in a number of synchronization environments. Each Alcatel-Lucent 1665 DMX can be provisioned to free run from an internal oscillator, line time from an incoming high-speed interface, or get external timing from the digital synchronization network via DS1/E1 references. Alcatel-Lucent 1665 DMX also supports distribution of timing references using DS1/E1 timing outputs.
Synchronization features
Alcatel-Lucent 1665 DMX supports three synchronization reference configurations:
•
External timing
from a Stratum 3 or better office clock (typical CO installations should be synchronized with DS1 or E1 timing references from a Stratum 3).
•
Line timing
from incoming high-speed OC-3/OC-12/OC-48/OC-192 signal (for small
COs or remote sites).
Line timing source cannot be derived from an LNW705 circuit pack.
•
Line timing from tributaries
derived from incoming low-speed OC-3/12/48 signal.
•
Free running
from the multiplexer's internal Stratum 3 Timing Generator (no synchronization inputs).
These timing modes are supported by the embedded Stratum 3 Timing Generator in the
OC-12, OC-48 or OC-192 circuit pack. The four basic timing modes can be combined into various network configurations. Line timing from high-speed lines is not available when using the LNW80 in the MAIN slots; line timing from tributaries is available when using the LNW80.
Internal timing functions such as reference interfaces, the on-board clock elements, and timing distribution, are provided by the Stratum 3 Timing Generator. The timing generator distributes clock and frame signals, derived from the selected reference source, to the transmission packs.
External timing mode
In external timing mode, the timing generator accepts two DS1 or E1 references from an external Stratum 3 or better clock. This Stratum 3 (or better) clock would typically be traceable to a primary reference source (PRS). The DS1/E1 references from the clock synchronize the local Alcatel-Lucent 1665 DMX with other network equipment operating under the Alcatel-Lucent 1665 DMX primary clock source. A high-stability digital phase-locked loop (DPLL) removes transient impairments on the DS1/E1 references for improved jitter performance.

The PRS is equipment that provides a timing signal whose long-term accuracy is maintained at 10
-11 or better with verification to universal coordinated time, and whose timing signal is used as the basis of reference for the control of other clocks in the network. Universal coordinated time is a time and frequency standard maintained by the
US National Institute of Standards and Technology.
Beginning in Release 9.1, the initial default state of the DS1 external timing source is in-service (IS). If the external timing source is invalid or missing, the system declares two alarms,
inc. DS1 sync. ref. LOS
and
holdover mode active
. Prior to 9.1, the default state of the timing source was AUTO and the external timing source was not alarmed.
Line timing mode
In line timing mode, the TG3 derives local shelf timing from the incoming service OC-3,
OC-12, OC-48, or OC-192 signal in the Main, Function Unit, or Growth slot. When provisioned for automatic protection switching and one of the OC-n references is corrupted or becomes unavailable, the TG3 makes a revertive or nonrevertive protection switch to the other reference without causing timing degradations. Synchronization reference mode switching can be either revertive or nonrevertive. You can also provision a primary reference. If all OC-n timing signals are lost, the TG3 switches to holdover mode. The TG3 normally switches back to line timing mode when a reference is no longer corrupted and clock mode switching is set to revertive. It can also be provisioned to require a manual switch. Switching between two OC-n reference inputs can also be done using a manual command. All optical circuit packs can derive a 6.48 MHz timing signal from an incoming optical line. DS1/E1 Sync Out is always derived from the provisioned line timing source.
Free running mode
In free running mode, no mode switching is performed. The timing generator derives timing from a high stability temperature-compensated, voltage-controlled crystal oscillator that has an end of life performance of ± 4.6 ppm. This oscillator is capable of
Stratum 3 accuracy. Only one Alcatel-Lucent 1665 DMX in a subnetwork can be provisioned in the free running mode. All other Alcatel-Lucent 1665 DMX NEs in the subnetwork must be line timed to this free running system to avoid performance degradation.
DS1/E1 timing output
Alcatel-Lucent 1665 DMX also supports a DS1 or an E1 timing output feature that facilitates network timing distribution. E1 timing outputs are available with the LNW59,
LNW82, or LNW504 VLF Main packs. The DS1/E1 timing output is derived from the
OC-n line rate, so it is not subjected to multiplexing or pointer processing effects. The result is a DS1/E1 traceable to the far-end source with extremely low jitter and wander.

The timing output can be locked to an OC-n line or the OC-n source can be automatically selected using synchronization messages. In either case Threshold AIS may be enabled to insert AIS if the synchronization message of the OC-n source matches a provisioned threshold.
The frame format on the DS1 output is provisionable as superframe format (SF) or extended SF (ESF). The E1 frame format can be provisioned as FAS or CRC4. The
DS1/E1 is a framed all-ones signal under normal conditions or an AIS signal under failure conditions.
SDH synchronization
With the use of the LNW59, LNW82, or LNW504 VLF Main pack, Alcatel-Lucent 1665
DMX supports E1 timing references. SDH synchronization conforms to industry standards for frequency accuracy, pull-in, hold-in and pull-out ranges, wander, jitter, noise tolerance, noise transfer, transient response, holdover performance (per ITU-T G.813), and for SDN Sync Status Messaging (per ITU-T G.704).
Dual reference monitoring (DRM)
With the use of VLF Mains, both external timing references are monitored simultaneously, even when the Timing Generator (TG) is in holdover mode. So, if an external reference fails, the Out of Lock (OOL) status of the standby reference is already known and the decision to switch to the standby reference can be made with certainty that the standby reference is not in an OOL condition. If the TG is in holdover mode, or if it has switched references with revertive reference switching enabled, it can monitor the
OOL reference(s) for a non-OOL condition and switch to the good reference with certainty that the reference is in fact not in an OOL condition. It will also autonomously clear the OOL alarm.
With non-VLF MAINs both external timing references are monitored for LOS, LOF, AIS,
BER & EOOF failures, but only the active reference can be monitored for frequency offset OOL failures, and only when the TG is locked to the reference. Frequency offset of either external reference cannot be monitored when the TG is in holdover or free-running modes.
When a failure of the active reference occurs, if reference switching is enabled, and if the standby reference doesn't have an LOS, LOF, AIS, BER & EOOF failure, the NE switches to the standby reference and locks to it, and then monitors its frequency offset for an OOL condition. If the standby reference does have an OOL failure, the TG goes into holdover mode and issues a major sync alarm for both references failed (subject to
ASAP provisioning).

Holdover mode
When line or external timing is used, in case of unprotected synchronization reference failure, the TG3 will switch to "holdover mode" and continue to provide system timing using the internal oscillator to maintain the last known good reference frequency. If the
DS1/E1 timing output is enabled for network synchronization, DS1 or E1 AIS is inserted on detection of unprotected optical reference failure.
Network configurations
Overview
The following pages detail the three different network configuration types: free running/line timing, external timing/line timing, and external timing.
Free running/line timing configuration
For initial SONET deployment with DS1 and/or DS3 low-speed interfaces, minimum first cost may be a primary concern. The free running/line timing network can operate without an external clock source, so the expense of connecting to one is eliminated. This configuration may be useful for initial access transport and customer location applications, and also meets the needs of an end-office trunk facility. This configuration should not be used to provide OC-n timing distribution or where SONET interconnections to other SONET networks are needed.
The local Alcatel-Lucent 1665 DMX times its transmitted signals at the low- and high-speed interfaces from the internal ±4.6 ppm of the Stratum 3 timing generator. The remote Alcatel-Lucent 1665 DMX recovers timing from the incoming OC-n signal and uses this timing for its transmitted signals.
Certain interconnected equipment may be sensitive to such jitter and this configuration should not be used in cases where it would cause a problem for that equipment. In particular, downstream equipment containing Stratum 3 or better clocks could be sensitive to this jitter.

Line timing from main interfaces vs. line timing from tributaries
The figure below shows various Alcatel-Lucent 1665 DMX shelves in line timing mode.
The top portion of the figure shows the present mode of operation where line timing references must be derived from optical lines entering the Main network interface circuit packs.
The bottom portion of the figure represents Alcatel-Lucent 1665 DMX's capability to derive timing references from optical lines entering both the Main and tributary interface circuit packs. Line timing source cannot be derived from an LNW705 circuit pack. Line timing from tributary interfaces is supported. Alcatel-Lucent 1665 DMX can utilize tributary line timing when equipped with VLF Mains (LNW59/LNW82/LNW504),
Non-VLF Mains (all other Main interface optical packs), and headless Main (LNW80) packs.
As shown in the top right of the figure below, the only two shelves that can serve as line timing sources in the present mode of operation are the two furthest to the right. This is because they are connected Main to Main, while the other shelves are transmitting optical

External timing/line timing configuration
The external timing/line timing configuration integrates access transport and customer location networks into the digital synchronization network as required by the SONET standard. This application is ideal for networks where only one location has a building integrated timing supply (BITS) clock, for example, access transport. The network is synchronized to a local central office clock via DS1 references. The local office clock should be Stratum 3 or better, with timing traceable to a primary reference source. The local Alcatel-Lucent 1665 DMX times its transmitted signals at the low- and high- speed interfaces from the internal oscillator that is locked on the external reference. The remote
Alcatel-Lucent 1665 DMX recovers timing from the incoming OC-n (OC-3/12/48/192) signal and uses this timing for its transmitted signals.
External timing is required when EC-1 low-speed interfaces are used to interconnect the local Alcatel-Lucent 1665 DMX with other SONET equipment. Thus, the external timing/line timing configuration should be the long-term goal for all access transport and customer location applications.

External timing configuration
The external timing configuration uses external DS1 or E1 timing to each Alcatel-Lucent
1665 DMX in the network. Since it requires local office clocks at each site, it is most suited to interoffice applications. An Alcatel-Lucent 1665 DMX network may have all
DS1/E1 references traceable to a common primary reference source (for example, out-state trunking) referred to as synchronous, or to multiple primary reference sources
(for example, a carrier-to-carrier interface). The multiple primary reference source is referred to as plesiochronous operation. The figure below shows an external timing configuration.
A tributary signal (for example, DS1) that traverses several plesiochronous regions may encounter increased STS-1 and VT pointer adjustments compared to that encountered in a synchronous environment. These pointer adjustments may increase jitter on the tributary when dropped from the SONET network. While standard jitter generation limits are perfectly acceptable for most service needs, some data services or other equipment may

be particularly sensitive to jitter-induced degradations. Therefore, it is generally desirable to minimize the number of plesiochronous regions within a network, through Stratum 1 clock traceability and line timing of remote SONET elements.

Timing distribution
Network timing distribution
DS1 signals have long been used to pass timing information through the network synchronization hierarchy. With an LNW59, LNW82, or LNW504 VLF Main, E1 timing outputs are also supported. These DS1/E1 timing references should be transmitted between master and slave clock sources over the most reliable facilities available. In some cases, these DS1/E1 signals also carry traffic. The facility of choice has evolved from
T-carrier through asynchronous lightwave systems to SONET lightwave systems. As these systems are upgraded to SONET systems, timing distribution plans should be revisited to ensure the quality of the timing signals are not degraded. With proper planning, SONET can be used to improve the overall quality of the network timing.
Interoffice timing distribution
One way SONET can be used to improve the quality of interoffice network timing is through the use of OC-n (OC-3/12/48/192) timing distribution. Alcatel-Lucent 1665
DMX supports the evolution to interoffice OC-n timing distribution by providing a
DS1/E1 timing output derived from the incoming OC-n signal. The DS1/E1 timing output is traceable to the clock source that times the Alcatel-Lucent 1665 DMX subnetwork and has extremely low jitter and wander. This is true regardless of the number of
Alcatel-Lucent 1665 DMX systems connected in the network. This DS1/E1 can be fed to the local BITS clock which subsequently times the local Alcatel-Lucent 1665 DMX and the other equipment in the office. If a BITS clock is not available in the office, the
DS1/E1 timing output can be used to time other equipment (including another
Alcatel-Lucent 1665 DMX) directly. Alcatel-Lucent 1665 DMX can provide DS1/E1 timing outputs in all supported topologies (for example, add/drop and ring) in the main slots. It also supports line timing from tributary optical interfaces, allowing
Alcatel-Lucent 1665 DMX to provide DS1 timing outputs even when equipped with the
LNW80 headless main. E1 timing outputs are available only when an LNW59, LNW82, or LNW504 Main is used.
With OC-n timing distribution, the OC-n line signal, rather than a DS1/E1 multiplexed into the SONET payload, will provide a timing transport mechanism better suited to a complex, heavily interconnected SONET network. In this configuration, a DS1 reference

from the CO BITS clock still times the OC-n transmitted to the remote site. At the remote site, a DS1/E1 output reference is created directly from the received OC-n signal, as shown in the figure below (E1 not pictured).

Potential advantages
OC-n (OC-3/12/48/192) timing distribution has several potential advantages. It preserves transport bandwidth for customer services and guarantees a high-quality timing signal.
Also, as the CO architecture evolves to replace DSX interconnects with SONET EC-1 interconnects and direct OC-n interfaces, OC-n distribution becomes more efficient than multiplexing DS1 references into an access facility in the CO.
A previous drawback to using OC-n timing distribution was that the network timing failures could not be communicated to downstream clocks via DS1 AIS, since the DS1 signal does not pass over the OC-n interface. A standard SONET synchronization messaging scheme to convey synchronization failures is now in place. Alcatel-Lucent
1665 DMX supports this synchronization messaging scheme. With this option, clock
Stratum levels can be passed from NE to NE, allowing downstream clocks to switch timing references without creating timing loops, if a network synchronization failure occurs. If a quality timing reference is no longer available, Alcatel-Lucent 1665 DMX sends AIS over the DS1 interface. If the local OC-n lines fail, Alcatel-Lucent 1665 DMX outputs AIS on the DS1 output or an upstream Alcatel-Lucent 1665 DMX enters holdover.
Access network timing distribution
OC-n (OC-3/12/48/192) timing distribution can also be used in access networks or to small COs. In this configuration, a DS1 reference from the CO BITS clock still times the
OC-n transmitted to the remote site. The line timing capability of Alcatel-Lucent 1665

DMX provides the ability to recover OC-n timing. The DS1 timing output feature can be used to also extend timing to customer networks or remote sites. In this case, the DS1 timing output may be used to time switch remotes, Alcatel-Lucent 1665 DMX shelves, or other local equipment directly. Ideally, the equipment can provide an external timing reference. Otherwise, the signal must be input to a traffic DS1 port on the external equipment which will tie up some of this equipment's bandwidth. In this configuration, it is important that the DS1 reference to the Alcatel-Lucent 1665 DMX in the CO be traceable to the same clock used to source the DS1s being carried to the customer site or small CO. If it is not, slips may occur.
Alternate timing sources
Although an ideal source of timing, OC-n timing distribution, via a DS1 timing output, cannot be used to provide timing in all applications. In cases where the local equipment is not provided with an external timing reference input, or in some private networks where the timing is to be distributed from another private network location, timing may be distributed via traffic-carrying DS1s. In these applications, a stable DS1 timing source can be achieved by ensuring that all elements in the SONET network are directly traceable to a single master clock via line timing. In this environment, the high-performance desynchronizer design of Alcatel-Lucent 1665 DMX allows a DS1 timing reference to be carried as a multiplexed DS1 payload.
It is recommended that, where possible, the DS1 sources (switch, PBX, or other equipment) be traceable to the same timing source used to time Alcatel-Lucent 1665
DMX SONET network. Multiplexed DS1 reference transport is also consistent with current planning and administration methods. Applications include passing synchronization from the public switched network to a PBX-based private network
( Figure 6-19, “Timing from multiplexed DS1” (p. 6-81) ) and synchronizing an end-office
remote switch to a larger office's host switch.
Important! Synchronous operation via line timing eliminates the generation of VT pointer adjustments, thus maintaining the phase stability needed for a high-quality
DS1 timing reference. Cross-connecting at the STS-1 level also eliminates the VT pointer adjustments. While the design of the Alcatel-Lucent 1665 DMX maintains jitter/wander within standard DS1 interface requirements, even in the presence of VT pointer adjustments, and while the DS1 is likely to be stable enough for most equipment to use as a timing reference, some equipment may have more stringent stability requirements for its timing references.

Synchronization messaging
Overview
Alcatel-Lucent 1665 DMX provides a synchronization messaging feature to ensure the integrity of network synchronization during both normal and abnormal conditions.
Through the use of synchronization messaging, the current quality of the timing source can be conveyed from one Alcatel-Lucent 1665 DMX to the next. This capability allows the Alcatel-Lucent 1665 DMX to automatically change its timing reference in order to always maintain the highest quality timing available. The capability also allows
Alcatel-Lucent 1665 DMX to inform a local BITS clock when the DS1/E1 timing output has been degraded and should no longer be used as a reference. This synchronization messaging feature is compliant with the scheme developed in the ANSI T1X1 standards committee.
Also, the same parameter used to choose between DS1 and E1 timing outputs is employed to choose between SONET sync messaging (ANSI T1X1 mentioned above) and
SDH sync messaging.

Applications
The applications supported with the synchronization messaging feature can be divided into three categories:
• DS1/E1 timing output integrity
• Automatic synchronization reconfiguration
• Synchronization provisioning integrity.
DS1 timing output integrity
The derived DS1 timing outputs are typically used as a synchronization reference to a
BITS clock which provides the timing reference to an externally-timed Alcatel-Lucent
1665 DMX. The synchronization reference is derived from the SONET transmission facility which is synchronized from an upstream timing reference. In this way, the timing from the BITS clock in one office (master) is distributed to the next office (slave) using the SONET transmission facilities between them as the synchronization vehicle.
The BITS are typically capable of synchronizing to a Stratum 3 or better accuracy.
Alcatel-Lucent 1665 DMX equipped with the embedded Stratum 3 timing generator is capable of synchronizing to a ± 4.6 ppm clock or better. The Stratum timing hierarchy requires that clocks of equal or better Stratum level be used to synchronize other clocks.
In this way, the Stratum timing hierarchy is preserved under all failure conditions. Under non-failure conditions, Alcatel-Lucent 1665 DMX does not introduce its own internal timing source onto the SONET facility, but merely transfers the quality of its timing reference. A failure of all derived DS1 timing references to the BITS at the master office will cause the BITS to enter holdover mode, whose minimum accuracy is dependent on its internal clock. If the BITS internal clock is of equal or better Stratum level than
Alcatel-Lucent 1665 DMX, the externally-timed Alcatel-Lucent 1665 DMX will use this reference to synchronize all outgoing SONET transmission facilities. This preserves the required hierarchical structure of the timing network and should be maintained at all times.
If the externally-timed Alcatel-Lucent 1665 DMX at the master office enters holdover due to a disconnected reference cable or a local BITS failure, the quality of the derived
DS1 timing output at the slave office will now be traceable directly to the Alcatel-Lucent
1665 DMX. The Stratum timing hierarchy is violated if the slave office BITS requires timing accuracy better than the Stratum level provided by the master Alcatel-Lucent 1665
DMX's internal clock. Because the Alcatel-Lucent 1665 DMX contains the embedded
Stratum 3 Timing Generator, Stratum 3 accuracy is maintained indefinitely. This provides acceptable timing for Stratum 3 NEs at slave offices.
Stratum timing rules are also violated when at least one line-timed Alcatel-Lucent 1665
DMX exists at a site between the master and slave offices. In this scenario, a fiber cut between the master office and the line-timed site will cause the line-timed Alcatel-Lucent

1665 DMX to enter holdover (with accuracy dependent upon its internal clock). If the
BITS at the slave office requires a higher accuracy clock than that generated by the
Alcatel-Lucent 1665 DMX in holdover, the Stratum timing hierarchy is violated.
Automatic synchronization reconfiguration
SONET was designed to operate optimally in a synchronous environment. Although plesiochronous and asynchronous operation can be supported through the use of pointer adjustments, transmission quality is affected by the generation of additional jitter and wander due to pointer adjustments. Because of this, it is desirable to maintain synchronous operation whenever possible. Through the use of synchronization messages, the quality of the different timing references can be made available at each Alcatel-Lucent
1665 DMX NE. Alcatel-Lucent 1665 DMX can be optioned to determine the best timing reference available and switch to that reference. Through this mechanism, the synchronous operation of the subnetwork can be maintained. The switching of timing references is hitless, and the synchronization messages also allow it to be done without creating timing loops in the process.
Access ring network
Under normal operation, the access ring network, shown below, has one Alcatel-Lucent
1665 DMX shelf externally timed and the others line timed. If a fiber failure occurs between the first two Alcatel-Lucent 1665 DMX shelves, the synchronization auto-reconfiguration feature causes Alcatel-Lucent 1665 DMX shelves to change their line timing directions to the opposite direction. The result is that the ring is again

operating synchronously. The ring already provides self-healing of the traffic, so it is especially important to maintain synchronous operation during this type of failure to prevent service degradation due to increased jitter and wander.

Synchronization provisioning integrity
Synchronization messaging also helps prevent provisioning errors. Provisioned timing loops on Alcatel-Lucent 1665 DMX are quickly detected through the synchronization messaging algorithm and prevented by forcing a shelf into holdover. The system can then be reprovisioned correctly.
Sync messaging feature details and options
Overview
As mentioned previously, SONET sync messaging is used to communicate the quality of the subnetwork timing throughout the subnetwork. This is done using the S1 byte in the
SONET or SDH overhead and is supported in the DS1 or E1 external timing reference inputs and outputs. If an Alcatel-Lucent 1665 DMX shelf is deriving timing from a given
OC-n interface, and sync messaging is enabled on that interface, the system interprets the received message to determine the system's timing status. The system also determines the state of the DS1 output, if the DS1 output is enabled, by forcing a DS1 AIS on the DS1

sync outputs if the timing status received on the OC-n interface is below a provisioned quality threshold. Alcatel-Lucent 1665 DMX also supports E1 timing output when equipped with a VLF Main circuit pack.
Alcatel-Lucent 1665 DMX also transmits over the particular OC-n interface, and all other
OC-n interfaces that are enabled for sync messaging, the appropriate message indicating the quality of its timing and its usability.
Important! When the Alcatel-Lucent 1665 DMX is provisioned for SONETSYNC, both input ext timing reference and ext refrence output are DS1. When the
Alcatel-Lucent 1665 DMX is provisioned for SDHSYNC, both input ext timing reference and ext reference output are E1.
Sync messages using S1 byte
The following table lists the associated internal timing status and DS1/E1 output states that are associated with sync messages (using the S1 byte) received from the OC-n interface when sync messaging is enabled. The same parameter used to choose between
DS1 and E1 timing outputs is employed to choose between SONET sync messaging and
SDH sync messaging. Messages are listed from low to high quality.

Disabling sync messaging
Sync messaging using the SONET S1 byte can be disabled on a per OC-n interface basis.
A

"Don't use" (DUS)
The
DUS message is sent to indicate that its timing is not suitable for synchronization (for example, back towards the line timing source).
External timing with SYNC OUT
When Alcatel-Lucent 1665 DMX is configured for external timing and its DS1/E1 output port is provisioned for the SYNC OUT mode, the DUS is sent on the OC-n interface towards the NE from which the DS1/E1 timing output is being derived. The Synchronized

- Traceability Unknown (STU) message is sent on all other OC-n interfaces where sync messaging is provisioned. If the DS1/E1 output is generating AIS while the system is configured in this way, the message STU is transmitted on all OC-n interfaces.
TG3 with free running or holdover
When using the embedded TG3, if Alcatel-Lucent 1665 DMX is configured for free running or is in holdover mode, the Traceable Stratum 3 message is sent on all OC-n interfaces for which sync messaging is enabled.
Line timing
When Alcatel-Lucent 1665 DMX is configured for line timing, the
DUS message is sent on the OC-n interface towards the NE from which the timing is being derived. The message received on the OC-n interface is sent on all other OC-n interfaces where sync messaging is enabled.
Automatic synchronization reconfiguration
With automatic synchronization reconfiguration, the Alcatel-Lucent 1665 DMX shelves receive and compare the incoming sync messages on the OC-n interfaces available for line timing to select the highest quality synchronization reference available. If the received quality levels are the same on the references available for timing, the active line timing reference takes precedence. This feature guarantees the non-revertive operation of reconfiguration. Although a revertive option is supported.
The existence of automatic synchronization reconfiguration does not affect OC-n line protection switching.
Hitless timing and equipment switching
Hitless timing equipment switching enables switching from an active timing generator
(TG) on one Main circuit pack to the TG on the other Main circuit pack without incurring transmission hits on any of the Main, Function Unit, or Growth circuit packs. This feature is only available on the VLF Main packs (LNW59/LNW82/LNW504). Low-speed, tributary OLIUs that allow hitless timing switching include the following: LNW45,
LNW49, LNW55. DS1 & DS3 signals/cards are asynchronous, and are not affected by a timing switch. Ethernet packs are also unaffected.

Sync messaging examples
Overview
In this section, some detailed examples are given to show specifically how the sync messages propagate through network and assist in the recovery from a fiber failure.
Through these examples, one can extend the same concept to any other network that may include different topologies, number of sites, failure locations, and number of BITS clocks. Some examples are depicted in a linear configuration because the particular sync messaging concept is more easily conveyed in linear terms. Those concepts can be applied to Alcatel-Lucent 1665 DMX ring networks.
Derived DS1 with no synchronization auto-reconfiguration using externally timed ring
Part "a" of the figure below illustrates an externally timed access ring operating in its normal configuration. The Alcatel-Lucent 1665 DMX shelf at Site A is externally timed from a BITS clock referenced to a Primary Reference Source (PRS). The remaining
Alcatel-Lucent 1665 DMX shelves (Sites B, C, and D) are externally timed from a BITS referenced to a derived DS1 timing reference output. The STU message is sent to indicate where timing is traceable to an external BITS and where it is valid to be used. Automatic synchronization reconfiguration is not an option for externally timed Alcatel-Lucent 1665
DMX shelves. Therefore, a change in the sync message will not cause an automatic synchronization reconfiguration. In part "b", a fiber has been cut between Sites A and B.
Immediately, Alcatel-Lucent 1665 DMX at site B changes the format of its derived DS1

Synchronization auto-reconfiguration in an access ring
Part "a" of the figure below illustrates an access ring operating in its normal configuration. The Alcatel-Lucent 1665 DMX shelf at the CO is externally timed, and each of the other Alcatel-Lucent 1665 DMX shelves are line timed in a counterclockwise direction. The STU message is sent to indicate where timing is traceable to an external
BITS and where it is valid to be used. The DUS message is sent on the interface that is being used as the line timing reference and, thus, where using that timing would create a timing loop. Sync messaging and automatic synchronization have both been enabled for this network.

Frequently asked network timing distribution questions
Overview
The following are some frequently asked questions about network timing distribution.
1. How do I time Alcatel-Lucent 1665 DMX shelves in a central office environment?
Each Alcatel-Lucent 1665 DMX should be externally referenced to the BITS clock in the office. If a BITS clock is not available in the office, a traffic-carrying DS1 from the local switch may be bridged (for example, using a bridging repeater) as the reference to the Alcatel-Lucent 1665 DMX. Line timing the Alcatel-Lucent 1665
DMX may also be used, but at least one Alcatel-Lucent 1665 DMX in the network must be externally timed.
2. Where do I use the DS1 timing output feature?

Frequently asked network timing distribution questions
....................................................................................................................................................................................................................................
The primary application is for supplying one source for the BITS clock timing input reference. This allows the BITS clock to be slaved to a BITS clock in another office that is, in turn, traceable to the primary reference source (PRS). Typically, the
Alcatel-Lucent 1665 DMX supplying the DS1 timing output will, in turn, be externally timed by the BITS clock. The BITS clock should only derive one of its timing reference inputs from a particular network. Its other reference should be derived from another network to assure that it does not enter holdover mode.
If there is no BITS clock, the DS1 timing output can be used to time a switch or switch remote (if the switch remote is equipped for that option) directly- or even another Alcatel-Lucent 1665 DMX.
3. How do I prevent my BITS clock from using a DS1 timing output when a failure in the
network results in this DS1 being timed from a SONET NE in holdover?
SONET sync messaging informs the local Alcatel-Lucent 1665 DMX of this condition, and AIS is inserted on the DS1 timing output.
4. What is the advantage of using the DS1 timing output instead of a multiplexed DS1 as
the timing reference?
The DS1 timing output is derived from the optical line rate and is superior because:
• The DS1 is virtually jitter-free
• Sync messages guarantee the traceability of the timing
• Administration of traffic DS1s for timing is eliminated.
5. Can I ever use the Alcatel-Lucent 1665 DMX in the free running timing mode?
If a PRS traceable external reference is available, it is the recommended timing mode for any/all CO applications. The free running timing mode can be used but a slight increase in jitter will result. If one Alcatel-Lucent 1665 DMX is provisioned for free running, all other Alcatel-Lucent 1665 DMX NEs in the network must be line timed and SONET interfaces to other equipment are not allowed. The DS1 timing output should not be enabled with a free running network.
6. How do I provide timing to a central office host switch that does not have the option
for an external reference?
A DS1 carried over SONET may contain significant jitter/wander and be unacceptable to the switch as a timing reference. If the central office has a BITS clock, the recommendation is to use the output from the BITS clock into an unused DS1 traffic port on the switch. If the central office does not have a BITS clock, the recommendation is to use the DS1 timing output from the Alcatel-Lucent 1665 DMX as the line timing reference into an unused DS1 traffic port on the switch.
7. Can a DS1 carried over SONET ever be used as a timing reference?

....................................................................................................................................................................................................................................
YES! In many applications there is no other choice. Most switch remotes, for instance, obtain their timing from a specific DS1 signal generated by their host switch, so these remotes must time from the DS1 signal. In addition, DLC equipment, channel banks, and PBXs will not likely have external references and may be allowed to line time from a DS1 carried over SONET.
8. Are there any specific concerns when using a DS1 carried over SONET to time
equipment such as a switch remote or DLC?
Yes. The major concern is to make sure all the equipment is synchronous. The
Alcatel-Lucent 1665 DMX NEs should be synchronous to each other to prevent pointer adjustments. This can be accomplished by having one source Alcatel-Lucent
1665 DMX that is externally timed. The other Alcatel-Lucent 1665 DMX NEs in the network should be line timed, or they should be externally timed to a clock to which they provide a DS1 timing output. The Alcatel-Lucent 1665 DMX NEs should also be synchronous to the switch to prevent excessive mapping jitter. This can be done by synchronizing the host switch to the BITS clock used to reference the Alcatel-Lucent
1665 DMX.
9. Will I have any problems providing timing to a customer that has a high quality PBX
or switch?
If the network is completely synchronous, as described in the previous answer, there should be no problems. If the PBX is sensitive to the jitter produced, even under the synchronous conditions, the DS1 timing output of Alcatel-Lucent 1665 DMX may be required to be used as a timing reference to this equipment.
10. Why does Telcordia® say that DS1s carried over SONET should not be used for
timing?
Telcordia
®
has provided this recommendation because there are several limitations.
Telcordia
®
says that DS1s carried over SONET must be used in applications such as switch remotes and will be acceptable, provided pointer adjustments are not created.
11. Can pointer adjustments be prevented?
Neither random nor periodic pointer adjustments will occur if the Alcatel-Lucent
1665 DMX shelf is provisioned for line timing.
12. How do I time Alcatel-Lucent 1665 DMX at a remote site?
Line time.
13. How many Alcatel-Lucent 1665 DMX NEs can I chain together in an add/drop
configuration before the timing becomes degraded?

Frequently asked network timing distribution questions
....................................................................................................................................................................................................................................
The Stratum level traceability of the nth node in an add/drop chain is the same as that in the first node. Also, while timing jitter will theoretically increase as the number of nodes is increased, the high quality timing recovery and filtering on the
Alcatel-Lucent 1665 DMX allows add/drop chains to be extended to any practical network limit without detectable increases in jitter levels. In practice, the only effects on timing at the nth node will occur whenever high-speed protection switches occur in any of the previous n-1 nodes. These effects should be rare.
14. How do I time a Alcatel-Lucent 1665 DMX ring network?
An interoffice ring should have each node externally timed if BITS clocks are available. All other rings should have one node externally timed (two in some dual homing architectures) and the rest of the nodes line timed. Synchronization reconfiguration is automatic.
15. Why are there more issues related to timing with SONET equipment than there are
with asynchronous equipment?
SONET equipment was designed to work ideally in a synchronous network. When the network is not synchronous, mechanisms such as pointer processing and bit-stuffing must be used and jitter/wander increases.
16. Can DS3 signals be used to carry DS1 timing signals without the worry of having the
network synchronous?
Yes, although this option is more expensive.
17. What are the limitations on automatic synchronization reconfiguration?
Automatic synchronization reconfiguration is only available when the Alcatel-Lucent
1665 DMX is provisioned for line timing mode. This allows the timing direction of an
OC-n (OC-3/12/48/192) ring network to change automatically in response to a failure.
When the Alcatel-Lucent 1665 DMX is provisioned for external timing, automatic synchronization reconfiguration is not available. When an OC-n fault is detected in the timing direction, AIS is inserted on the derived DS1s which forces the BITS to switch to another good timing source or into holdover preventing timing loops.
18. How do I synchronize a BITS clock and maintain automatic synchronization
reconfiguration on a Alcatel-Lucent 1665 DMX ring?
Provision all but the host node (node with co-located PRS) for line timing. Provide each non-host BITS clock with a pair of derived DS1s. The Alcatel-Lucent 1665
DMX will detect faults and provide the BITS clocks with good inputs if available.
Timing loops will be prevented. The host node should be set for external timing and get its timing from an externally timed BITS clock. To prevent a timing loop, the host
BITS clock should get its timing from a PRS traceable source. The non-host nodes should not be timed from the co-located BITS clock since this would disable the automatic synchronization reconfiguration feature.

IS-IS Level 2 routing guidelines
Overview
Purpose
This section details the guidelines for IS-IS Level 2 Routing in networks larger than 250
OSI nodes.
The following topics are included in this section:

Introduction
Purpose
If network sizes of more than 250 OSI nodes are required, hierarchical routing makes it possible to increase the number of nodes in an OSI management domain, (for example,
NEs with OSI LAN and/or DCC connectivity for operations communications among the
NEs). Increasing the number OS nodes is achieved through the use of IS-IS Level 2
Routing.
IS-IS Level 2 Routing involves assigning NEs to multiple areas of 250 nodes or less.
Level 2 routers support OSI communications between the NEs in different areas. Both the assignment of NEs to areas and the enabling of NEs as Level 2 routers is accomplished by provisioning. For additional information, see
“Area address assignment” (p. 6-99)
and
“Level 2 router assignment” (p. 6-100) , respectively.

OSI node vs. NE terminology
Each Alcatel-Lucent 1665 DMX is an OSI node, but some other NEs support multiple
OSI nodes within a single NE, so the term "OSI node", or simply "node", is generally used in this context instead of "NE".
Advantages
The primary advantage of IS-IS Level 2 Routing is to limit the OSI routing information that needs to be maintained by each node. Each node within an area maintains routing tables to route OSI LAN and DCC messages to the other nodes in the same area. If a node needs to route a message to a node in a different area, the node relies on a Level 2 router in its own area to route the message to a Level 2 router in the target area and from that
Level 2 router to the target node within that area.
The Level 2 routers route messages between nodes in different areas. These messages include all of the NE-NE (and OS-NE) OSI communications required for the supported
OI applications, (for example, TL1 login messages from TL1–GNEs to TL1-RNEs.)
In addition to maintaining a routing table to route messages to other nodes in the same area, Level 2 routers need to maintain routing information for the Level 2 routers in all other areas (but not for all nodes within each of those other areas).

Area address assignment
Area address
The area address is the first 26 characters of each Alcatel-Lucent 1665 DMX Network
Services Access Point (NSAP). [Alcatel-Lucent 1665 DMX supports a fixed-length
40-character (20-byte) NSAP only.] The first eight characters of the NSAPs are always the same and cannot be changed. The remaining 18 characters of the NSAP area address are provisionable but only the Area field should be changed to assign a node to a different area. The remainder of the NSAP includes the System Identifier field, which is unique to each node, and the Selector (SEL) field.
The following table provides a break-down of an NSAP.

A group of nodes are assigned to an area by changing each node's NSAP Area field to the same value. The entire NSAP area address must be identical for all nodes in an area and different from the NSAP area addresses for all other areas.
If more than one separate area with the same area address exists, routing to these areas from other areas would not be predictable and couldn't be expected to function properly.
Area field
The Area field consists of four hexadecimal characters, with a default value of 0000
(hex). TL1 command
ENT-ULSDCC-L3
can be used to change the Area field.
Area terminology
Despite the technical differences between the area address and the Area field described previously, the term area address is commonly used to refer to the Area field value. Thus, for convenience, the term area address is used throughout this document.

Multiple area addresses
Multiple area addressing is the capability for a node to be assigned more than one area address. The provisioning of multiple area addresses is not supported on Alcatel-Lucent
1665 DMX, directly.
Level 2 router assignment
Overview
OSI communications is supported within a network which may consist of a single area or multiple areas. Level 1 routers provide interconnectivity between nodes in an area (all
Alcatel-Lucent 1665 DMX are Level 1 routers). Level 2 routers provide connectivity between areas.
Guidelines and default
In a network with multiple areas, each area must contain at least one Level 2 router. An area without a Level 2 router would be isolated from the rest of the network. The adjacent set of Level 2 routers form the Level 2 sub-domain. For proper OSI routing, every Level
2 router should have at least one neighbor (via OSI LAN or DCC) that is also a Level 2 router. At least one of the Level 2 routers in an area must be adjacent to a Level 2 router in another area, otherwise, the former area would be isolated from the rest of the network.
Each Alcatel-Lucent 1665 DMX is not a Level 2 router by default. TL1 command
ENT-ULSDCC-L3
can be used to enable any Alcatel-Lucent 1665 DMXas a Level 2 router.
IS-IS Level 2 routing remote provisioning sequence
Avoid isolating nodes
An important goal is to avoid isolating any nodes when provisioning area addresses and
Level 2 routers remotely. Isolating a node may require craft dispatch to the isolated node to recover. To avoid isolating nodes, the sequence for remote provisioning is established with respect to the local node to which the WaveStar
®
CIT is connected or the TL1–GNE through which OMS is connected. Typically, the local node or TL1–GNE is provisioned to be a Level 2 router first, but its area address is not changed initially. This general sequence can be modified in networks with redundant OSI LAN or DCC connectivity between and within areas.
1. The nodes and sub-tending rings that are furthest away from this local node or
TL1–GNE are provisioned first.
2. Work back toward the local node or TL1–GNE's sub-tending ring.

....................................................................................................................................................................................................................................
3. Provision the local node or TL1–GNE's sub-tending ring.
4. Provision the local node or TL1–GNE last.
If OMS is part of the network via an OSI LAN or WAN interface, provision the area address for the OMS.
Important! Before assigning area addresses and Level 2 routers in a network, be sure no alarms (especially
DCC failure alarms) exist; otherwise, even the recommended remote provisioning sequence might result in isolated nodes. To confirm the network alarm status, it is recommended that a centralized maintenance center with TL1 OS support be consulted.
Provisioning sub-tending rings
Always provision new area addresses for a sub-tending ring by starting with a node that is adjacent to the node that connects this sub-tending ring to the rest of the network, and then provision the area address for each sequential adjacent node going around the sub-tending ring. Provision the area address of the connecting node last, especially if the connecting node supports multiple sub-tending rings.
For single-homed sub-tending rings, provision the node that will be the Level 2 router node last; otherwise, nodes in its area could be isolated. For dual-homed rings, provision one of the nodes that will be Level 2 router first, so that OSI connectivity is established with provisioned nodes as soon as they complete their controller resets.
Both DRI and dual-homed rings are designed to protect against a failure of an interconnecting facility or a failure of the node at which the interconnection occurs. The choice of DRI or dual-homing is driven by the network topology. To provide protection when connecting between two UPSRs, use DRI. To provide protection when connecting between a UPSR and a single NE, use dual homing.
Minimizing OSI communications disruption
Another important goal is to provision the network in such a way that OSI communications disruption is minimized. Changing a node's area address and/or enabling a node as a Level 2 router causes the node to reset its controller. The reset is immediate and is part of the completion of the command. In addition to temporarily disrupting OSI communications, controller resets temporarily disable automatic transmission protection switching.
As one node is undergoing a controller reset in an area, the next adjacent node should be provisioned to minimize the overall time required to provision the nodes in an area and minimize the time that OSI communications with the nodes in the area are lost.
Changing a node's area address and enabling a node as a Level 2 router, if appropriate, should usually both be done with a single command per node.

IS-IS Level 2 routing provisioning confirmation
Overview
TL1
RTRV-MAP-NETWORK
commands can be used to confirm the area address and Level
2 router assignments of all nodes with OS LAN or DCC connectivity in a network.
Small networks
In a small network without IS-IS Level 2 Routing, the
RTRV-MAP-NETWORK
response includes the NSAPs (including the embedded area address field) of the local node and all remote nodes. This command may also be useful to confirm the uniqueness of the area addresses before combining two existing networks into one large network requiring IS-IS
Level 2 Routing.
Large networks
In large networks with IS-IS Level 2 Routing, the
RTRV-MAP-NETWORK
response can vary based on whether or not the local node is a Level 2 router itself.
1. If the local node is not a Level 2 router, the response includes only remote nodes in the same OSI area as the local node and indicates which remote node is the default
Level 2 router for the local node.
The default Level 2 router is the node that the local node would rely on to route an
OSI message outside the local NE's own area. When there are multiple Level 2 routers in the same area, not all nodes in the area would identify the same default Level 2 router typically.
2. If the local node is a Level 2 router, user input dictates whether the response includes: a. only remote nodes in the same OSI area as the local node (as in #1 above) but indicating which of those remote nodes are Level 2 routers b. all remote nodes that are Level 2 routers across all OSI areas.
Thus, with a
RTRV-MAP-NETWORK
command to one Level 2 router in each area, all nodes in a large network with IS-IS Level 2 Routing can be identified. One
RTRV-MAP-NETWORK
command at a time per area should suffice and is recommended to avoid unnecessarily burdening the network with many simultaneous or redundant TARP queries.
Problem isolation
TL1 command
RTRV-MAP-NEIGHBOR
may indicate and help resolve IS-IS Level 2
Routing provisioning mistakes. This command highlights any neighbors with which DCC is enabled but OSI communications is not fully functional. When addressed to a reachable node with an unreachable neighbor, this command identifies the NSAP area address and

the Level 2 router status, if known, of the unreachable neighbor. The unreachable neighbor may simply have the wrong area address or both nodes may need to be enabled as Level 2 routers.
There is no standing alarm or status condition at a node with Level 2 router functionality enabled or disabled. There is no automatic means of determining whether the area address is consistent with the rest of the network. The user must confirm that all IS-IS Level 2
Routing rules have been followed to ensure successful OSI communications among the nodes in a network.
Maximum number of OSI nodes
Maximum number of nodes per area and OSI domain
The total number of nodes per OSI area cannot exceed 250. The total number of nodes in the OSI domain cannot exceed 1000.
Engineering rules and guidelines
Overview
To use IS-IS Level 2 Routing, the user must plan and engineer the provisioning of Level 2 routers and area addresses in the network.
The goal is to create a network with all nodes having OSI LAN or DCC connectivity with each other so that access to all the nodes can be gained from any node in the network.
Rules must be followed to assure OSI LAN and DCC message routing. Guidelines are recommendations that add survivability in the event of a node, OSI LAN or DCC failure.
Rules must be followed. Guidelines should be followed. There may be customer applications that cannot adhere to some or all of the guidelines. In most cases, the potential consequence is that a single failure would at least partially disrupt operations communications.

Guideline: redundant routes within the Level 2 sub-domain
When practical, redundant routes in the Level 2 sub-domain should be available between all Level 2 routers to ensure that proper routing will occur in the event of a single failure.
To satisfy this guideline, every Level 2 router has at least two other Level 2 routers as direct neighbors.

Guideline: Level 2 router area assignments in a ring
For a ring of Level 2 routers, the recommended area assignments may be one of the following:
• All Level 2 routers are part of the same area.
• Each Level 2 router is part of a different area.
• A pair of adjacent Level 2 routers are in the same area (for example, with dual-homing or DRI), with either the other Level 2 routers similarly paired off or individually in different areas.

Guideline: OMS own area address and Level 2 router
If OMS (or any other OS) access is via OSI LAN (or WAN), OMS should be assigned to a different area and rely on a generic Level 2 router to communicate with a large network.
(OMS is not expected to be a Level 2 router itself.) This is recommended to avoid routing all messages to/from OMS through a single NE serving as a Level 2 router.
Although not shown in the examples below, OMS can support a second, redundant OSI

Rule: Level 2 routers on an OSI LAN
If an OSI LAN (or WAN) is used to connect between areas, then at least one node in each area on the OSI LAN must be provisioned to be a Level 2 router. Otherwise, the areas won't route to each other via the OSI LAN.
Figure 6-33, “Level 2 router assignments on an OSI LAN” (p. 6-113)
illustrates a correct and an incorrect example of Level 2 router assignments on an OSI LAN:

Guideline: OSI LAN redundancy
If an OSI LAN (or WAN) is the only method of connecting between areas, then at least two Level 2 routers directly connected to the OSI LAN for each area are recommended for redundancy purposes. A second, separate OSI LAN hub would provide additional redundancy.
Figure 6-34, “OSI LAN redundancy” (p. 6-114)

Introduction
....................................................................................................................................................................................................................................
Any information about particular pieces of equipment (i.e. the uses of various cables versus other) is meant to convey useful information that may/may not be contained in the engineering drawings. This information is meant to be used in conjunction with engineering drawings, but not to replace them.
How to order
Equipment and software orders may be placed via Alcatel-Lucent's online ordering process. For more information, contact your Account Executive.
Sparing information
Overview
This section provides guidelines and a procedure to determine the number of spares needed at each location.
Important! The number of spares for each code must be determined and maintained separately, based on the in-service population of the code at each location.
Lead time
Lead time, or turnaround time is the elapsed time between a known FRU failure at a given service location and the arrival of a repaired (or new) FRU at the location where spare circuit packs are stocked to maintain a spare FRU level consistent with the population in service.
Lead time should not be confused with mean time to repair, which is the elapsed time between discovery of the failure of an in-service FRU and when a replacement is put into service.

Using the sparing graph
Use the following procedure to determine how many spare circuit packs, PTMs, or other pieces of equipment are required for each code at each location to maintain 99.9% service continuity, given a 10-day lead time.
1. Locate the failure rate for the unit under consideration using the tables above.
2. See
Figure 7-1, “Sparing graph for a 10-day lead time” (p. 7-3)
and select the curve that represents the nearest failure rate. Interpolation may be necessary.
3. Follow the curve until it intersects the vertical line that represents the number of units in service at the given location. Interpolation may be necessary.
4. Refer to the horizontal line immediately above the intersection. The number associated with this line is the minimum number of spares recommended for that location.
5. Repeat Steps 1–4 for each circuit pack, PTM, and piece of equipment.
Example of using the graph
If there are 100 LNW49 OC-12 OLIUs (failure rate of 4523) in service at a given Central
Office location and your lead time is 10 days, then you should order and stock 3 spare
LNW49 circuit packs for that location.

Overview
This section provides information about software and documentation.
Software ordering information
The following list provides some need-to-know items before ordering Alcatel-Lucent
1665 DMX software:
• Alcatel-Lucent 1665 DMX software is shipped separately from the hardware.
Software orders must be placed in addition to the hardware order to receive software.
• Order one set of software for each shelf ordered.
• All system controller (SYSCTL) circuit packs are shipped without software loaded on them. Therefore, software loading must occur at or before installation.
• It may be desirable to have backup CD-ROMs for all releases on hand for backup or initial downloading.
• Release software includes a CD containing the current documentation to accompany the Alcatel-Lucent 1665 DMX. Hardcopies of the most current documentation are available through the Online Customer Support (OLCS) ( http://support.alcatel-lucent.

Lightguide build-outs
Alcatel-Lucent 1665 DMX utilizes Alcatel-Lucent's state-of-the-art
AllWave
ADVANTAGE TM
Fiber Optic Attenuators. These attenuators reduce optical power from the transmitter that can result in over-saturation of the receiver, have low reflection to meet stringent system requirements, and are backward-compatible with existing transmission systems. Unique to the AllWave ADVANTAGE optical connectivity solution (OCS), the
LC TM optic attenuators are designed to provide flat spectral loss across the full spectrum, allowing the attenuators to be used in the 1300 nm, 1400 nm, and 1500 nm bands. LC optical attenuators are ideal for networks deploying AllWave fiber, metropolitan or regional networks, applications supported by conventional single-mode optical fiber, multiservice network protocols, and DWDM networks.
Table 7-2, “Lightguide build-outs” (p. 7-7)
lists the available LC-type lightguide build-out attenuators for the Alcatel-Lucent 1665 DMX.

Notes:
1.
The LC build-out attenuators listed are polished connector (PC) style connectors at the fiber end. These attenuators must be used on the receive side in all cases. For the LNW37,
LNW45 OC-3 and LNW49 OC-12 circuit packs, the specified attenuation may not be achieved if a SM-MM (single-mode-multi-mode) fiber signal is incoming to the LC SM-SM attenuator. In this case, a 15 dB attenuator, for example, may achieve an attenuation value less than the specified 15 dB.
2.
The AllWave ADVANTAGE Fiber Optic Identification Kit includes labels for fiber optic apparatus products to identify Alcatel-Lucent AllWave Fiber paths. An instruction sheet is included with recommendations on how to install and use the labels.

Reliability program and specifications
Overview
The reliability program provides enhanced reliability and is implemented as an integral part of the Alcatel-Lucent Product Life Cycle (PLC) process. The reliability program is comprehensive, and includes activities such as setting and ensuring compliance with customer-focused system-reliability requirements, ensuring component qualification is consistent with use environment and system design, assuring satisfactory component-attachment reliability, predicting failure rates of Field Replaceable Units
(FRUs), making sparing recommendations, assessing reliability architecture, modeling system reliability, assuring satisfactory system-downtime performance, reducing hardware failure rates through Environmental Stress Testing (EST), and tracking field returns.
Design and development
During the design and development stage, reliability predictions, qualification and selection of components, definition of quality assurance audit standards, and prototyping of critical areas of the system ensure built-in reliability.
Manufacturing and field deployment
During manufacturing and field deployment, techniques such as environmental stress testing, production quality audits, field-return tracking, failure-mode analysis, and feedback and corrective-action further enhance the ongoing reliability improvement efforts on the Alcatel-Lucent 1665 DMX.
Environmental Stress Testing
Alcatel-Lucent 1665 DMX circuit packs are subjected to an Environmental Stress Testing
(EST) program. The purpose of the program is to improve reliability by reducing early life failures and implementing root-cause analysis and corrective action on circuit packs that fail EST.

Transmission downtime
Alcatel-Lucent 1665 DMX satisfies a stringent set of reliability specifications. Some of the critical specifications include Telcordia
®
downtime requirements and objectives for multiplexers. Telcordia
®
requirements state that the downtime of a two-way channel within a SONET multiplexer, due to hardware failure, must be less than 1.75 minutes per year in a Central Office (CO) environment and 5.25 minutes per year in a Outside Plant
(OSP) environment. The corresponding objectives for these parameters are 0.25 minutes per year in a CO environment and 0.75 minutes per year in an OSP environment. These requirements and objectives appear in Telcordia
®
GR-418-CORE.
These requirements and objectives apply to all system elements needed to process a two-way channel, including the core system as well as the high-speed and low-speed interfaces. System-reliability analysis employing Markov modeling is used to determine the system downtimes. As specified in Telcordia
®
GR-418-CORE, this analysis assumes a mean time to repair of 2 hours for the CO environment and 4 hours for the OSP environment. Individual Field Replacable Unit (FRU) failure rates used in the model were determined using the method described in Telcordia
®
SR-332, Reliability Prediction
Procedure for Electronic Equipment (RPP). FRUs are system elements that can be replaced in the field, including items such as circuit packs, removable optical interfaces, housings, cooling units, and removable LEDs.

DS3 TransMUX (LNW18)
Electrical specification
The TransMUX circuit pack provides 12 ports for DS3 service.
DS3 interfaces transmit/receive a standard electrical DS3 signal as specified in
GR-499-CORE, Section 9 (44.736 Mb/s rate, DSX-3 interconnect specification, bipolar
3-zero substitution (B3ZS) encoding).
TransMUX circuit pack DS1 and DS3 signals
Alcatel-Lucent 1665 DMX supports a 12-port TransMUX card that can collect various
DS1 signals from around a ring and combine them into a channelized DS3 signal.
The TransMUX circuit pack functions in the following manner:
Transmit functions
• Receives a B3ZS-encoded DS3 signal from a DSX-3
• Recovers DS3 clock and NRZ data
• Calculates parity errors on the DS3 input
• Demultiplexes the M13 or C-bit formatted DS3 signal into 28 DS1s
• Maps the 28 DS1s into VT1.5s and then into an STS-1
• Inserts STS-1 path overhead
• Provides the STS-1 signal to the OLIU circuit packs
Receive functions
• Interprets the STS-1 pointer values
• Terminates the STS-1 path
• Disinterleaves the STS-1 signal into 28 VT1.5s and interprets VT pointer values
• Converts the VT1.5 signals to 28 DS1 signals
• Multiplexes the 28 DS1 signals to an M13 or C-bit formatted DS3 signal
• B3ZS encodes the outgoing DS3 signal
• Pre-equalizes the DS3 signal (with LBO) and transmits it to a DSX-3

48DS3/EC1/TransMUX (LNW20)
Electrical specification
DS3 interfaces transmit/receive a standard electrical DS3 signal as specified in
GR-499-CORE, Section 9 (44.736 Mb/s rate, DSX-3 interconnect specification, bipolar
3-zero substitution (B3ZS) encoding).
The LNW20 provides 48 ports supporting DS3, EC1, and TMUX functionality on a port-by-port basis. Each port can be individually provisioned as DS3 or EC1
(unchannelized), or as TransMUX (channelized DS3s). With the LNW20, one high-density pack can be used for all DS3, EC1, and/or TransMUX applications.
LNW20 can be 1x1 protected or function in 0x1 unprotected mode. It supports hairpins to other packs in the shelf, and between ports on the same pack.
LNW20 can always occupy slots A1/A2 through D1/D2. Only certain Main packs can support the LNW20 in G1/G2 slots. Because the G1/G2 slots do not have any electrical backplane connections, only optical or "port-less TMUX" can work in the G slots. The following Mains support the LNW20 in G1/G2 slots and portless operation in all slots:
• OC-48: LNW27, LNW29, LNW76, LNW82, LNW202
• OC-192: LNW56, LNW58, LNW59, LNW502, LNW504
• Switch pack: LNW80

Unchannelized DS3 operation
The low-speed DS3 interfaces transmit/receive a standard electrical DS3 signal as specified in GR-499-CORE, Section 9 (44.736 Mb/s rate, DSX-3 interconnect specification, bipolar 3-zero substitution (B3ZS) encoding). However, the signal does not have to contain a standard DS3 frame.

DS3 portless mode of operation
The LNW20 can also function in portless mode. Portless mode does not utilize any of the electrical ports on the pack. When operating in portless mode, LNW20 converts channelized DS3 signals that enter Alcatel-Lucent 1665 DMX on a SONET STS-1 interface (on another pack) to VT mapped STS-1s. This VT-mapped STS-1 is cross-connected at the VT level in the Main packs (at least one side of the cross-connect is OCn/EC1) to any interface that supports the signal structure today (DS1, channelized
DS3, EC1, optical). Portless mode can be provisioned on a per-port basis when VLF
Mains are used. When non-VLF Mains are used, odd numbered ports can be configured as portless and the corresponding even-numbered port will be unavailable for service.

Notes:
1.
All terminology is consistent with GR-253-CORE, Issue 3. All values are worst-case end of life. Optical specifications meet or exceed equivalent GR-253-CORE requirements.
2.
The System Gain includes connector loss at the transmitter and receiver points S and R in GR-253-CORE,
Issue 3.
3.
Optical path penalty includes effects of dispersion, reflection, and jitter that occur on the optical path. The optical path penalty for 1310 nm optics is 1.0 dB maximum. The optical path penalty for the 1550 nm optics is 2.0 maximum.
4.
See GR-253-CORE for more information about these parameters.
5.
One additional connector (0.75 dB) on each end is assumed to connect station cable to outside plant.
6.
Additional unallocated margin, or safety margin, can be 0−3 dB. Typically, a 1.5 dB value is assumed.
7.
For all packs and PTMs where the Minimum Loss Budget (MLB) is 0, no attenuator is required for loopbacks. For all packs and PTMs where the MLB is greater than 0, an attenuator is required. The value of the LBO must be equal to or greater than the MLB.
8.
The stated maximum loss budget equals the System Gain, less the Optical Path Penalty, the Additional
Connector Loss Margin, and the Additional Unallocated Margin. The resultant Maximum Loss Budget is available for station cable loss, transmission cable loss, and splice loss.
9.
The approximate span length values are calculated per an attenuation assumption. As a general rule, for attenuation-limited systems, an attenuation of 0.45 dB/km is used for 1310 nm optics. This estimate includes typical cable loss (0.40 dB/km) and up to 11 splice losses (0.2 dB per splice). For 1310 nm OC-48 systems, dispersion is not a limiting factor, and the applications are attenuation-limited. For 1550 nm optics, an attenuation of 0.27 dB/km is used. Again, appropriate fiber-cable loss and numerous splice losses are

Lengths can be calculated more precisely based on particular fiber and splice characteristics and local engineering rules.

The following parameters are monitored on the OC-48 interface:
• LOS
• LOF
• AIS-L
• RFI-L (FERF)
• Signal Degrade (BER)

Connector Loss Margin, and the Additional Unallocated Margin. The resultant Maximum Loss Budget is available for station cable loss, transmission cable loss, and splice loss.
9.
The approximate span length values are calculated per an attenuation assumption. As a general rule, for attenuation-limited systems, an attenuation of 0.45 dB/km is used for 1310 nm optics. This estimate includes typical cable loss (0.40 dB/km) and up to 11 splice losses (0.2 dB per splice). For 1310 nm OC-48 systems, dispersion is not a limiting factor, and the applications are attenuation-limited. Approximate Span Lengths can be calculated more precisely based on particular fiber and splice characteristics and local engineering rules.

Low-speed OC-3 OLIU (LNW37 and LNW45)
Optical specification
The LNW37 and LNW45 OLIUs use Pluggable Transmission Modules (PTMs), also known as small form-factor plug-ins (SFPs), and is OSP hardened. PTM optics can be
"plugged" into the circuit pack as they become needed. Because the optics are pluggable, different ranges are available. The LNW37 and LNW45 can be equipped with OC-3
SR-1, IR-1, LR-1, or CWDM optics. These optics meet standard optical specs per
Telcordia
®
GR-253-CORE and ITU G.957.
The LNW37 supports 4 ports and the LNW45 supports 8 ports.
The multi-longitudinal-mode/Fabry-Perot (FP) laser is used for short or intermediate-reach transmission. Either a FP or a single-longitudinal-mode/distributed feedback (DFB) laser transmitter is employed in long-reach applications. The PTM optics for the LNW37 and LNW45 supply a 1310 nm, scrambled non-return-to-zero (NRZ) coded signal (155.52 Mb/s).
The LNW37 and LNW45 circuit pack and three OC-3 PTMs are approved for OSP deployments.
For system, transmitter, receiver, and link budget specifications, see
“OC-3 PTM optical specifications” (p. 10-65) .

Notes:
1.
All terminology is consistent with GR-253-CORE, Issue 3. All values are worst-case end of life.
2.
The System Gain includes connector loss at the transmitter and receiver points S and R in GR-253-CORE,
Issue 3.
3.
Optical path penalty includes effects of dispersion, reflection, and jitter that occur on the optical path. At
OC-12 rates, the optical path penalty is normally 1.0 dB for both 1310 nm and 1550 nm optics.
4.
Refer to GR-253-CORE for more information about these parameters.
5.
One additional connector (0.75 dB) on each end is assumed to connect station cable to outside plant.
6.
Additional unallocated margin, or safety margin, can be 0−3 dB. Typically, a 1.5 dB value is assumed.
7.
For all packs and PTMs where the Minimum Loss Budget (MLB) is 0, no attenuator is required for loopbacks. For all packs and PTMs where the MLB is greater than 0, an attenuator is required. The value of the LBO must be equal to or greater than the MLB.
8.
The stated maximum loss budget equals the System Gain, less the Optical Path Penalty, the Additional
Connector Loss Margin, and the Additional Unallocated Margin. The resultant Maximum Loss Budget is available for station cable loss, transmission cable loss, and splice loss.
9.
The Approximate Span Length values are calculated per an attenuation assumption. As a general rule, for attenuation-limited systems, an attenuation of 0.45 dB/km is used for 1310 nm optics. This estimate includes typical cable loss (0.40 dB/km) and up to 11 splice losses (0.2 dB per splice). For 1550 nm optics, an attenuation of 0.27 dB/km is used. Again, appropriate fiber-cable loss and numerous splice losses are included. For 1310 nm OC-3 and OC-12 systems, dispersion is not a limiting factor, and the applications are attenuation-limited. Approximate span lengths can be calculated more precisely based on particular fiber and splice characteristics and local engineering rules.

LR-2, or CWDM optics. These optics meet standard optical specs per Telcordia
®
GR-253-CORE and ITU G.957.
The IR-1 optics available for this circuit pack also conform to SR-1 specifications. Thus, the LNW49 can also be employed in short reach applications.
The multi-longitudinal-mode/Fabry-Perot (FP) laser is used for short or intermediate-reach transmission. A single-longitudinal-mode/ distributed feedback (DFB) laser transmitter is employed in long-reach applications. The IR-1 and LR-1 PTM optics for the LNW49 supply a 1310 nm, scrambled non-return-to-zero (NRZ) coded signal
(622.08 Mb/s). The LR-2 PTM optics for the LNW49 supply a 1550 nm, scrambled non-return-to-zero (NRZ) coded signal (622.08 Mb/s).
The LNW49 circuit pack some of the supported OC-N PTMs are approved for OSP deployments. You must install PTMs that are approved for industrial temperatures to use the LNW49 in OSP environments. All of the CWDM PTMs are approved for extended temperatures and are therefore only approved for Central Office environments.

The LNW55 OLIU circuit pack supports a maximum of 12 OC-3 ports, 12 OC-12 ports, or 4 OC-48 ports. Mixing port optical rates is supported with the following restrictions:
• OC-48 interfaces are only supported on ports 1, 4, 7, and 10.
• When port 1, 4, 7, or 10 is used for an OC-48 interface, then the next two adjacent ports are unavailable for use.

Single-port, high-speed OC-192 OLIUs (LNW56 and LNW58)
Optical specification
This section briefly details the optical specifications for the OC-192 LNW56 and LNW58 circuit packs.
LNW56
The LNW56 circuit pack is a high-speed, intermediate reach OLIU that meets or exceeds
SONET OC-192 1550 IR-2 specifications. The LNW56 circuit pack bridges span lengths up to 40 km. The LNW56 transmits in the general 1550 nm range.
LNW58 (optical interface for intra-office applications)
The LNW58 is a high-speed, very short reach (VSR) OC-192 OLIU that meets or exceeds
ITU G.693 VSR600-2R1 specifications. The LNW56 circuit pack bridges span lengths up to 600 meters. The LNW58 transmits in the general 1310 nm range.
System specifications
The table below lists the OC-192 OLIU system specifications.
Important! At high optical launch powers, SBS can cause an acoustic back-scattering phenomenon in fibers. The dither tone effectively broadens the spectrum of the narrow optical pulse, thus raising the threshold power where SBS becomes an issue.
For fibers carrying multiple wavelengths in DWDM systems, it should be noted that the individual channel (individual wavelength) power determines the SBS threshold, not the total composite power of all the channels.

Notes:
1.
All terminology is consistent with GR-253-CORE, Issue 3 and ITU G.693. All values are worst-case end of life. Optical specifications meet or exceed equivalent GR-253-CORE requirements.
2.
The system gain includes connector loss at the transmitter and receiver points S and R in GR-253-CORE,
Issue 3.
3.
Optical path penalty includes effects of dispersion, reflection, and jitter that occur on the optical path. The optical path penalty for 1310 nm is a maximum of 1.0 dB. The optical path penalty for 1550 nm is a maximum of 2.0 dB.
4.
Refer to GR-253-CORE for more information about these parameters.
5.
For all packs and PTMs where the Minimum Loss Budget (MLB) is 0, no attenuator is required for loopbacks. For all packs and PTMs where the MLB is greater than 0, an attenuator is required. The value of the LBO must be equal to or greater than the MLB.
6.
The stated maximum loss budget equals the minimum system gain, minus the optical path penalty.
Maximum loss budget is available for both station and transmission cable and splices.
7.
The Approximate Span Length values are calculated per an attenuation assumption. As a general rule, for attenuation-limited systems, an attenuation of 0.27 dB/km is used for 1550 nm optics. This estimate includes typical cable loss (0.22 dB/km) and up to 11 splice losses (0.2 dB per splice). For 1550 nm OC-192 systems, dispersion can also be a limiting factor. Approximate Span Lengths can be calculated more precisely based on particular fiber and splice characteristics and local engineering rules. Note that the 1310 nm VSR OC-192
LNW58 is recommended for spans of up to 600 meters only.

8-port, high-speed OC-3/12/48 VLF Main (LNW82)
Optical specification
The LNW82 OC3/OC12/OC48 OLIU circuit pack is an 8-port, PTM-based, multi-rate
(OC-3, OC-12, OC-48), high-speed optical circuit pack.
The LNW82 circuit pack and some of the supported OC-N PTMs are approved for OSP deployments. You must install PTMs that are approved for industrial temperatures to use the LNW82 in OSP environments. All of the DWDM PTMs are approved for commercial temperatures and are therefore only approved for Central Office environments.
The LNW82 OLIU circuit pack supports a maximum of 8 OC-3 ports, 8 OC-12 ports, or
2 OC-48 ports. Mixing port optical rates is supported with the following restrictions:
• OC-48 interfaces are only supported on ports 1 and 5.
• When port 1 or 5 is used for an OC-48 interface, then the next three adjacent ports are unavailable for use. For example, if an OC-48 pluggable transmission module is installed in port 1, then ports 2, 3, and 4 are unavailable for use.

....................................................................................................................................................................................................................................
1-port, high-speed OC-12 OLIU (LNW203)
Optical specification
The LNW203 OLIU uses Pluggable Transmission Module (PTM) optics. PTM optics can be "plugged" into the circuit pack as they become needed. Because the optics are pluggable, different ranges are available. The LNW203 can be equipped with IR-1, LR-1, or LR-2 optics. These optics meet standard optical specs per Telcordia
®
GR-253-CORE and ITU G.957.
The IR-1 optics available for this circuit pack also conform to SR-1 specifications. Thus, the LNW203 can also be employed in short reach applications.
The multi-longitudinal-mode/Fabry-Perot (FP) laser is used for short or intermediate-reach transmission. A single-longitudinal-mode/ distributed feedback (DFB) laser transmitter is employed in long-reach applications. The IR-1 and LR-1 PTM optics for the LNW203 supply a 1310 nm, scrambled non-return-to-zero (NRZ) coded signal
(622.08 Mb/s). The LR-2 PTM optics for the LNW203 supply a 1550 nm, scrambled non-return-to-zero (NRZ) coded signal (622.08 Mb/s).
The LNW203 circuit pack and the supported OC-12 PTMs are approved for OSP deployments. You must install PTMs that are approved for industrial temperatures to use the LNW203 in OSP environments.
For detailed system, transmitter, receiver, and link budget specifications, see
PTM optical specifications” (p. 10-69) .
Allowed optics for LNW203 packs
The table below lists the PTM optics that may be used in the LNW203 circuit pack.
Alcatel-Lucent 1665 DMX utilizes Pluggable Transmission Module (PTM) optics on the

8-port, high-speed OC-48/OC-192 VLF Main (LNW504)
Optical specification
The LNW504 OC48/OC-192 OLIU circuit pack is an 8-port, PTM-based, multi-rate
(OC-48/OC-192), high-speed optical circuit pack.
The LNW504 can only be used in Central Office environments.
The LNW504 high-speed circuit pack is an 8-port, multi-port., multi-rate (MPMR)
OC-48/OC-192 VLF Main circuit pack. LNW504 pack supports up to 4 OC-192 interfaces or up to 3 OC-192 interfaces and 4 OC-48 interfaces and has integrated STS and VT fabrics.
Note: Because the four OC-48 lines and the fourth OC-192 line share the same internal resources, the operation of OC-48 lines 5–8 is mutually exclusive of the operation of OC-192 line 4.
Mixed interface rates are supported with the following restrictions.
• OC-192 interfaces are only supported on ports 1–4
• OC-48 interfaces are only supported on ports 5–8
Note: The LNW504 faceplate port numbering starts from the bottom of the pack. Port
1 is at the bottom and port 8 is at the top.
For detailed system, transmitter, receiver, and link budget specifications, see:
•
“OC-48 PTM optical specifications” (p. 10-73)
•

8 channel DWDM Mux/Demux OMD5/8 (LNW785)
Optical specification
The LNW785 series supports supporting ITU-T DWDM channels 52 through 59
(195.20–195.90 THz). These channels, which have wavelengths between 1530.3 and
1535.8 nm, are at the short-wavelength end of the C-band. This region is chosen because it has the lowest chromatic dispersion in standard single-mode fiber (SSMF) and because it contains Alcatel-Lucent 1665 DMX's most popular DWDM channel, 59.
The LNW785 must be installed in a shelf with an LNW2 and at least one Main pack
(VLF or non-VLF).
Cross-connections
The following 1-way optical cross-connections are supported on the OCH interfaces of the LNW785.
• OCH to/from OCH pass-through cross-connections
• OCH to/from OTU2 add/drop cross-connections
• OCH to/from OC-192 Line add/drop cross-connections
• OCH to/from alien (remote shelf) add/drop cross-connections

Notes:
1.
All terminology is consistent with GR-253-CORE, Issue 3. All values are worst-case end of life. Optical specifications meet or exceed equivalent GR-253-CORE requirements.
2.
The OC-3/STM-1 CWDM PTMs can also operate as OC-12/STM-4 PTMs.
3.
x/y: x is using Fabry Perot (FP) and y is using Distributed Feed-Back (DFB) laser.
4.
The System Gain is Minimum Transmitter Power minus Minimum Received Power.
5.
Optical path penalty includes effects of dispersion, reflection, and jitter that occur on the optical path. The optical path penalty for 1310 nm optics is normally 1.0 dB.
6.
Refer to GR-253-CORE for more information about these parameters.

7.
For all packs and PTMs where the Minimum Loss Budget (MLB) is 0, no attenuator is required for loopbacks. For all packs and PTMs where the MLB is greater than 0, an attenuator is required. The value of the LBO must be equal to or greater than the MLB.
8.
The stated maximum loss budgets are assumed to be worst-case values including losses due to splices, connectors, optical attenuators or other passive optical devices, and any additional cable margin.

Notes:
1.
All terminology is consistent with GR-253-CORE, Issue 3. All values are worst-case end of life (EOL).
Optical specifications meet or exceed equivalent GR-253-CORE requirements.
2.
The System Gain is Minimum Transmitter Power minus Minimum Received Power.
3.
Optical path penalty includes effects of dispersion, reflection, and jitter that occur on the optical path. The optical path penalty for 1310 nm optics is 1.0 dB maximum. The optical path penalty for the 1550 nm optics is 2.0 dB maximum.
4.
Refer to GR-253-CORE for more information about these parameters.
5.
For all packs and PTMs where the Minimum Loss Budget (MLB) is 0, no attenuator is required for loopbacks. For all packs and PTMs where the MLB is greater than 0, an attenuator is required. The value of the LBO must be equal to or greater than the MLB.
6.
The stated maximum loss budgets are assumed to be worst-case values including losses due to splices, connectors, optical attenuators or other passive optical devices, and any additional cable margin.
7.
The target distance assumes no passive optical units are being used.
8.
Although not specified, the OC-48 XFPs may tolerate some amount of negative dispersion, approximately
−100 ps/nm.
9.
CWDM optical path penalty includes effects of dispersion, reflection, and jitter and a 0.3 dB penalty due to optical filters and cross-talk.
10.
The CWDM target distance is dispersion-limited at the 1611 nm wavelength and attenuation-limited at the
1471 nm wavelength.

Lightguide jumpers and build-outs
Overview
Alcatel-Lucent 1665 DMX provides standard LC-type connectors on all optical interfaces. 5 dB, 10 dB, 15 dB, and 20 dB attenuating build-outs are supported.
Single-mode jumpers
The OC-3, OC-12, OC-48, OC-192, and 1000BASE-LX lightguide interfaces use single-mode jumpers for connecting to and from the outside plant LGX panel and
Alcatel-Lucent 1665 DMX.
Multi-mode jumpers
The 1000BASE-SX interface must use multi-mode jumpers.
Build-outs
Alcatel-Lucent 1665 DMX supports the use of single-mode to single-mode (SM-SM) fiber exclusively, except on the 1000BASE-SX interface.
Reference
For more information, including a complete list of available jumpers and build-outs, see
“Miscellaneous equipment and tools” (p. 7-7)
in
Multimode fiber transmission with OC-3 and OC-12 circuit packs
Overview
The OC-3 and OC-12 circuit packs can transmit signals over Multi-Mode Fiber (MMF).
OC-3 and OC-12 circuit packs used on Alcatel-Lucent 1665 DMX are designed to meet or exceed Optical Performance Standards per Telcordia
®
GR-253-CORE on standard
Single-Mode Fiber (SMF). This section reflects the results of tests demonstrating successful transmission over shorter distances of MMF. Based on this testing, transmission of OC-3 and OC-12 signals over MMF can be supported by an
Alcatel-Lucent 1665 DMX system equipped with LNW37, LNW45, LNW49, LNW50,
LNW55, or LNW82 circuit packs within the limits specified.

MMF core diameters are specified to be 50 mm or 62.5 mm.
Receiver ports
All existing Alcatel-Lucent 1665 DMX circuit pack codes that utilize OC-3 or OC-12 optical interfaces incorporate optical receiver ports that accept optical inputs from fiber cores up to 62.5 mm in diameter. Therefore, the receivers are designed to capture all of the incoming light from both SMF and MMF.
Transmitter ports
The LNW37, LNW45, LNW49, LNW50, LNW55, or LNW82 circuit packs utilize optical interfaces that incorporate laser transmitter ports designed to launch into 8−10 mm SMF.
The laser transmitters in these circuit packs are Distributed Feedback (DFB) or Single
Longitudinal (SLM) mode lasers.
Recommendations
With multi-mode fiber specified to meet 1 GbE fiber standards per the original IEEE
802.3zTM (now found in IEEE 802.3-2002) and rated at 500 MHz-km or greater,
"Single-mode Fiber Offset-Launch Mode- Conditioning Patch Cords" (Mode-
Conditioning Patch Cord) are required for the transmitter ports of LNW37, LNW49, and
LNW50 circuit packs. Mode-Conditioning Patch Cords take the transmitter port output from the single-mode fiber and couple it to the multi-mode fiber core at an offset. This offset launch into the MMF minimizes differential mode delay and modal dispersion.
With the use of Mode-Conditioning patch cords, transmission distances of up to 300 meters are allowed. See
With improved, recently introduced MMF specified to exceed 1 GbE fiber standards, transmission distances of up to 300 meters are allowed without the use of
Mode-Conditioning patch cords. Several manufacturers offer this improved MMF (see the table below). These fibers, or their equivalents, do not require Mode-Conditioning patch cords when used with the LNW37, LNW49, and LNW50 circuit pack codes.

Ethernet (LNW63)
....................................................................................................................................................................................................................................
4-port 1000BASE-X/T (optical/electrical) Private Line
Ethernet (LNW63)
Description
The LNW63 provides 4 PTM ports that can be equipped with very long-reach
(1000BASE-ZX) 1550 nm, long-reach (1000BASE-LX) 1310 nm, and/or short-reach
(1000BASE-SX) 850 nm optical PTMs. LNW63 can also be equipped with
100/1000BASE-T electrical Ethernet PTMs, although only 1000BASE-T rates are supported on the LNW63.
The LNW63 provides data transport at the rate of 1000 Mbps using standard encapsulation, and standard STS-1 virtual concatenation according to ITU G.707. The
LNW63 is an unprotected pack.
The LNW63 contains 4 internal 1000 Mbps WAN ports supporting enhanced Private Line services such as high-order virtual concatenation (VT1.5) and Link Capacity Adjustment
Scheme (LCAS).
The LNW63 and the supported PTMs are approved for OSP deployments. You must install PTMs that are approved for industrial temperatures to use the LNW63 in OSP environments.
When Alcatel-Lucent 1665 DMX is equipped with non-VLF Main packs, LNW63 packs can only be placed in Slot 1 of any Function Group or Growth slot in the shelf (A1–G1) and Alcatel-Lucent 1665 DMX supports a total add/drop capacity of 20 Private Line GbE ports if all available slots are equipped with LNW63 circuit packs. If the LNW63 circuit packs occupy only slot 1 of a Function Unit group, slot 2 must be populated with an apparatus blank.
When Alcatel-Lucent 1665 DMX is equipped with VLF Main (LNW59, LNW82, or
LNW504) packs, Ethernet packs can occupy both Slot 1 and 2 of a Function or Growth
Unit. With VLF Mains and all tributary slots populated with LNW63 packs,
Alcatel-Lucent 1665 DMX provides a total add/drop capacity of 40 Private Line GbE ports.
Optical specification
The LNW63 utilizes 1000BASE-SX/LX/ZX PTM optics.

FC-DATA: FICON/ESCON/Fibre-Channel (LNW73 and LNW73C)
SAN transport interface
Description
The LNW73 and LNW73C are 4-port Storage Area Networking (SAN) interface cards designed to facilitate SAN distance extensions vian Alcatel-Lucent 1665 DMX using
GFP-T (ITU G.7041). These cards employ standard encapsulation, and standard STS virtual concatenation according to ITU G.707. For extended FC/FICON interfaces, the
LNW73/73C also supports buffer_to_buffer credit management spoofing consistent with
ANSI T11 FC-BB-3_GFPT draft standard.
They utilize PTM optics to provide the option of FICON, ESCON, or Fibre-channel interfaces natively on the Alcatel-Lucent 1665 DMX shelf. Each pack must be equipped to support only one type of traffic at a time (FICON/FC or ESCON). The LNW73/73C can operate at 1 Gbps or 2 Gbps. When the pack is operating at 2 Gbps only every other port may be used. Therefore, the total number of SAN interfaces on an Alcatel-Lucent
1665 DMX shelf varies depending on the main circuit packs, equipage and configuration of the ports.
When Alcatel-Lucent 1665 DMX is equipped with non-VLF Main packs, LNW73/73C packs can only be placed in Slot 1 of any Function Unit group or Growth slot on the shelf
(A1–G1). If all available slots are equipped with LNW73/73C circuit packs,
Alcatel-Lucent 1665 DMX supports a total add/drop capacity of 20 when the LNW73/73c is operating at 1G FC/FICON or ESCON and 10 when LNW73/73C is operating at 2G
FC/FICON. If the LNW73/73C circuit packs occupy only slot 1 of a Function Unit group, slot 2 must be populated with an apparatus blank.
When Alcatel-Lucent 1665 DMX is equipped with VLF Main (LNW59, LNW82, or
LNW504) packs, Ethernet packs can occupy both Slot 1 and 2 of any Function Unit group or Growth slot on the shelf (A1–G1). With VLF Mains and all tributary slots populated

FC-DATA: FICON/ESCON/Fibre-Channel (LNW73 and
LNW73C) SAN transport interface
....................................................................................................................................................................................................................................
with LNW73/73C packs, Alcatel-Lucent 1665 DMX provides a total add/drop capacity of
40 when the LNW73/73c is operating at 1G FC/FICON or ESCON and 20 when
LNW73/73c is operating at 2G FC/FICON.
While the capacity of each port is 2 Gbps, the true capacity of each port is relative to the type of PTM it is equipped with. For ESCON traffic, the PTM ports have a capacity of
200 Mbps. The 2 Gbps capacity of the ports is sufficient to support FC2G and FICON
Express.
The LNW73C differs from the LNW73 in that it enables compression of asynchronous
FC traffic. The LNW73C is able to conserve up to 50% of bandwidth versus uncompressed SAN traffic in typical applications. SAN compression enables a high throughput of up to two full-line rate FC-2G interfaces in a single pack.
Optical specification
The LNW73 and LNW73C can utilize both 1000BASE-LX and 1000BASE-SX PTM optics. Both the 1000BASE-LX and 1000BASE-SX optics can support FICON traffic.
The LNW73/73C can also utilize ESCON PTM optics for ESCON traffic. These PTM optics can be ordered and plugged into the LNW73/73C as their capacity becomes needed.
For the detailed specifications of these optics, see:

Description
The LNW74 circuit packs provide 16 10/100BASE-T, IEEE 802.3-compliant electrical interfaces (via the backplane of the shelf) that are capable of spanning distances of 100 meters. The LNW74 also provides 8 optical 100BASE-ZX/LX/FX IEEE 802.3-compliant
(100 Mbps) fast Ethernet interfaces. The LNW74 is a Private Line circuit pack.
The 10/100T interface function is full duplex mode and auto-negotiates speed (10/100
Mbps) when interfacing with other 802.3-compliant devices over twisted pair media. The
LNW74 circuit pack must be housed in slot 1 of a Function Unit group and is not equipment protected. However, facility protection can be provided through the WAN via
SONET (UPSR, BLSR, or 1+1). The LNW74 also supports low- and high-order
(STS/VT) VCAT.
When Alcatel-Lucent 1665 DMX is equipped with non-VLF Main packs, LNW74 packs can only be placed in Slot 1 of any Function or Growth group in the shelf (A1–G1) and
Alcatel-Lucent 1665 DMX supports a total capacity of 64 10/100BASE-T electrical ports and 40 100BASE-X optical ports if all available slots are equipped with LNW74 circuit packs. When the LNW74 circuit packs occupy only slot 1 of a Function Unit group, slot 2 must be populated with an apparatus blank.
When Alcatel-Lucent 1665 DMX is equipped with VLF Main (LNW59, LNW82, or
LNW504) packs, LNW74 packs can occupy Slot 1 and Slot 2 of any Function or Growth group (A1–G1). The Port Configuration of the circuit packs must be provisioned as FX to support LNW74 packs in both companion slots. With VLF Mains and available tributary slots populated with LNW74 packs, up to 64 10/100BASE-T electrical ports and 40
100BASE-X optical ports are provided if all available slots are equipped with LNW74 circuit packs and the Port Configuration of the circuit packs is FT_FX. Additional ports can be added if the companion slot to the LNW74 is populated with a compatible front-access Ethernet pack, like an LNW170. With VLF Mains and available tributary slots populated with LNW74 packs, up to 80 100BASE-X optical ports are provided if all available slots are equipped with LNW74 circuit packs and the Port Configuration of the circuit packs is FX.
In all scenarios, when the LNW74 is installed in slot G1 or G2, the Port Configuration of the circuit pack is FX and only optical PTMs can be used.

100/1000BASE-X/T (optical/electrical) Ethernet (LNW170)
Description
The LNW170 circuit packs provide four 1000BASE-X (SX, LX, and/or ZX- very long reach 80km), IEEE 802.3-compliant (1000Mbps) GbE interfaces and four
100BASE-ZX/LX/FX IEEE 802.3-compliant (100 Mbps) fast Ethernet interfaces. The
LNW170 circuit packs provide Ethernet private line or switched services, with QoS.
Protection is provided via SONET UPSR/BLSR or through the IEEE 802.1w (or 802.1d) spanning tree algorithm.
The LNW170 can also use electrical PTMs that are provisionable to support either
100BASE-T or 1000BASE-T traffic. The electrical PTMs can occupy ports 1−8.
The LNW170 is an unprotected pack by default. Alcatel-Lucent 1665 DMX supports link aggregation on LNW170 LAN ports, which can be used to provide facility protection.
The LNW170 can also support aggregation across LNW170 circuit packs. For more information on Link Aggregation, see
“Link aggregation” (p. 5-59) .
When Alcatel-Lucent 1665 DMX is equipped with non-VLF Main packs, unprotected
LNW170 packs can only be placed in Slot 1 of any Function Unit group or Growth slot on the shelf (A1–G1) and Alcatel-Lucent 1665 DMX supports a total add/drop capacity of 20 1000BASE-X ports and 20 1000BASE-ZX ports if all available slots are equipped with LNW170 circuit packs. If the LNW170 circuit packs occupy only slot 1 of a
Function Unit group, slot 2 must be populated with an apparatus blank. However, the
LNW170 can be populated on both slots with non-VLF Mains if it is in equipment-protected mode.
When Alcatel-Lucent 1665 DMX is equipped with VLF Main (LNW59, LNW82, or
LNW504) packs, Ethernet packs can occupy both Slot 1 and 2 of a Function or Growth
Unit (where applicable). With VLF Mains and all tributary slots populated with LNW170 packs, up to 40 1000BASE-X and 40 100BASE-LX ports are addressable.
Optical specification
The LNW170 can utilize 1000BASE-X optics. The LNW170 can also utilize
100BASE-X PTM optics for optical fast Ethernet. These PTM optics can be ordered and plugged into the LNW170 as their capacity becomes needed.

Allowed Ethernet/SAN PTM transceivers
Overview
Alcatel-Lucent 1665 DMX utilizes Pluggable Transmission Modules (PTMs), also known as small form-factor plug-ins (SFPs), transceivers on the LNW63, LNW64, LNW73/73C,
LNW74, LNW87, LNW170, LNW705, and LNW910 circuit packs. To ensure proper optical performance, mechanical fit, compliance with EMC, and compliance with laser safety standards, the Alcatel-Lucent specified PTM transceivers listed in the table below must be used.
Only the Alcatel-Lucent specified PTM transceivers listed below are compatible with
Alcatel-Lucent 1665 DMX software. If non-Alcatel-Lucent specified PTM transceivers are installed in Alcatel-Lucent 1665 DMX, the system will reject that transceiver, and that optical port will become inoperable (until approved parts are installed).

SONET overhead bytes
Purpose
Alcatel-Lucent 1665 DMX uses SONET transport and path overhead bytes as specified in
GR-253-CORE.
V4 byte
The reserved V4 byte in the VT1.5 superframe is sometimes used for internal error detection in an Alcatel-Lucent 1665 DMX shelf. This internal usage of the V4 byte may cause the value of a transmitted V4 byte to vary. The Alcatel-Lucent 1665 DMX always ignores the value of the V4 byte received from another network element as required by
GR-253-CORE.

Synchronization
Overview
The embedded Stratum 3 Timing Generator meets the specifications of GR-253-CORE,
SONET Transport Systems Generic Criteria. The timing generator function is embedded in the 1x1 protected optical interface circuit packs in the main slot pair.
Timing modes
The timing generator supports four timing modes:
•
External timing
Locked to an external Stratum 3 (±4.6 ppm) or better DS1/E1 reference.
•
Line timing
Locked to recovered clock from an OC-N signal (from Main or tributary
OC-3/OC-12/OC-48/OC-192).
Line timing source cannot be derived from an LNW705 circuit pack.
•
Free running
Timing derived from high-stability temperature-compensated voltage-controlled crystal oscillator (TCVCXO) with a long-term accuracy of ±4.6 ppm and temperature stability of −40º C to +65ºC.
•
Holdover
Timing derived from the internal oscillator in the case of an unprotected synchronization reference failure. In this instance, the Stratum Timing Generator switches to "holdover mode" and continues to provide system timing, using the internal oscillator to maintain the last known good reference frequency. If the DS1/E1 timing output is enabled for network synchronization, DS1/E1 AIS will be inserted on detection of unprotected optical reference failure. In holdover mode, the accuracy is
±.37 ppm over the full −40°C to +65ºC temperature range.
•
DS1/E1 timing outputs
In addition, each timing generator (main circuit pack) provides a single DS1 or E1 sync output derived from a received optical interface signal (OC-N). These DS1/E1 timing outputs may be used to provide a timing reference signal to a local BITS clock
For more information, see
Chapter 5, “Operations, administration, maintenance, and provisioning” .

DS1 timing functions
The DS1 timing reference inputs and outputs meet the specifications of GR-499-CORE for DS1 interfaces and GR-253-CORE for timing references. The following are the DS1 timing functions:
• Two DS1 timing reference inputs
• Two DS1 timing reference outputs
• Alarms (Out of Frame, AIS, BER).
E1 timing functions
The E1 timing reference inputs and outputs meet the specifications of ITU-T G.813 for frequency accuracy, pull-in, hold-in and pull-out ranges, wander, jitter, noise tolerance, noise transfer, transient response and holdover performance. E1 references also comply with ITU-T G.704 standards for SDN SSM. The following are the E1 timing functions:
• Two E1 timing reference inputs
• Two E1 timing reference outputs
• Alarms (Out of Frame, AIS, BER).
Protection switching
1+1 networks
Alcatel-Lucent 1665 DMX complies with SONET 1+1 unidirectional and bidirectional revertive and nonrevertive protection switching requirements as specified in
GR-253-CORE. Automatic line switches are initiated by signal fail and signal degrade conditions on the received low-speed (OC-3/12/48) or high-speed (OC-12/48/192) optical signal and are completed within 50 milliseconds of a signal failure. The signal's BER is calculated from violations of the SONET line overhead B2 parity bytes. Signal fail is declared for incoming LOS, LOF, line AIS, or BER exceeding a provisionable 10
−3 to
10
−5 threshold, while a BER exceeding a provisionable 10
−5 to 10
−9 threshold causes the signal degrade condition. Manual switch commands are available through the local and remote operations interfaces.
Important! Alcatel-Lucent 1665 DMX supports Bidirectional Optimized 1+1 Linear
Protection Switching per ITU-T G.841 Annex B. Bidirectional optimized 1+1 is designed to enable interoperability between Alcatel-Lucent 1665 DMX and SDH equipment. It is a separate switching scheme from standard 1+1 bidirectional and does not work with standard 1+1.
Alcatel-Lucent 1665 DMX also supports non-revertive bidirectional 1+1 switching to enable interworking between Alcatel-Lucent 1665 DMX and Ciena Core Director.

High-speed UPSR networks
Path protection rings feed a SONET payload (STS or virtual tributary [VT]) from the ring entry point, simultaneously in both rotations of the ring, to the signal's ring exit point. The node that terminates the signal from the ring monitors both ring rotations and is responsible for selecting the signal that has the highest quality based on LOS, LOF, and path BER performance. On pass-through paths, all detected hard failures (LOS, LOF, line
AIS, or STS-1 path AIS) result in VT AIS insertion in the outgoing signals. This allows the terminating node to be aware of the failure and to switch to protection. Protection switching is completed within 50 milliseconds of failure detection.
Under normal conditions, both incoming SONET path signals to the switch selection point are of high quality, and the signal can be selected from either ring. A failure or transmission degradation on one of the rings requires that the other ring path be selected.
On a per STS-n basis, Alcatel-Lucent 1665 DMX supports both revertive and non-revertive switching. In non-revertive applications, when and if the critical service should revert to a particular ring, a manual path protection switching command allows switching back to the original path for ease of ring maintenance.
Low-speed UPSR networks
On low-speed SONET optical interfaces (OC-3/12/48/192), UPSR is optional and protection switching is provisionable (UPSR or 1+1) on a per-line basis.
BLSR
Alcatel-Lucent 1665 DMX supports OC-192 and OC-48 2-fiber BLSR protection groups in the high-speed or low-speed slots, with STS-n cross-connectivity between any BLSR working tributary and the tributaries of all supported interfaces. This includes BLSR to
BLSR cross-connections. Limited support is also provide for VT cross-connections (large fabric non-VLF mains only) and Extra Traffic). BLSR through cross-connections are also supported. However, cross-connections between different tributaries (timeslots) on the east and west ports of the ring are not supported. The BLSR ring map may be provisioned manually or automatically discovered. The squelch map entries may be manually provisioned or automatically generated. The BLSR switching is GR-1230-CORE complaint. However, external switch requests that must be signaled on the DCC channels are not supported.

TL1/LAN
Overview
Alcatel-Lucent 1665 DMX supports a TL1 over TCP/IP interface or TL1 over OSI LAN interface for communication between an Alcatel-Lucent 1665 DMX NE and an Element
Management System (EMS) of a Network Management System (NMS). TL1 over
TCP/IP LAN complies with requirements specified in IEEE 802.3 and NSIF-AR-9806-
088R11.
TL1 translation device (T-TD Gateway)
The T-TD is a device that translates TL1 messages over a TCP/IP connection to a TL1 over OSI association, providing a TL1 TCP-OSI gateway. The T-TD, when used in conjunction with the CIT, is an open system interconnection (OSI) proxy that accepts
TCP/IP connections and sets up matching OSI connections. This requires the support of the TCP/IP stack and the seven-layer OSI stack.
Front IAO LAN interface
Alcatel-Lucent 1665 DMX provides an RJ45-compatible front IAO LAN interface that is intended for use with a local PC. This interface will support a TL1/TCP gateway via an
IEEE 802.3-compliant interface with a graphical user interface (GUI) in future releases.
Rear IAO LAN interface
TL1 over TCP/IP or TL1 over OSI LAN is supported via an RJ45-compatible IAO LAN rear interface on Alcatel-Lucent 1665 DMX, enablingAlcatel-Lucent 1665 DMX to connect with any NMS possessing a compatible TCP/IP or OSI interface (such as the
EMS or the WaveStar
®
CIT). This allows TL1 communication over a data network between several different NEs. For instance, Alcatel-Lucent's Element Management
System (EMS) can communicate with a DDM-2000 that is on the same network as
Alcatel-Lucent 1665 DMX connected to the EMS via the rear IAO LAN interface. The
IAO LAN complies with OSI requirements as specified in GR-253-CORE, Section 8.
SONET DCC
The SONET DCC provides TL1 over OSI connections with remote NEs in a subnetwork.

Introduction to Ethernet services
Ethernet services
Ethernet services are what network operators provide their subscribers. Alcatel-Lucent
1665 DMX supports Private Line, Private LAN, Virtual Private LAN, and Virtual Private
Line.
The Private services are transported over their own dedicated SONET time slots. If present, Ethernet switching functions may or may not be shared.
Subscribers of Virtual Private services share network bandwidth to take advantage of the efficiency of statistical multiplexing that is available due to the intermittent nature of data transmission. VLAN Tags are used to separate subscribers and maintain privacy.
Alcatel-Lucent 1665 DMX supports VLANs in the 1–4093 range for customer identification and isolation.
Private Line services are point-to-point in nature while Private LAN services are multipoint. Private LAN services always involve internal Ethernet switching while
Private Line services do not.
Private line
Private Line service provides a dedicated link between two locations. The Ethernet ports and SONET bandwidth are dedicated to the subscriber and not shared. Private line service is characterized by minimal provisioning - typically just the SONET cross-connection. A subclass, Fractional Private Line, is distinguished by less than Ethernet-line-rate SONET connectivity. It is a form of rate control that also improves efficiency by only consuming the required SONET bandwidth in STS-1 increments. For more information about how
STS-1 tributaries can be virtually concatenated to provide Fractional Private Line service, see
“Virtual concatenation” (p. A-24) .
Another characteristic of Private Line service is little or no Layer 2 functionality. With
Fast Ethernet, the physical layer must be terminated precluding transparency of auto-negotiation. In addition, performance of the Fractional Private Line may be improved by enabling flow control, a Layer 2 function. For more information about flow control, see
MAC address learning is another function. For more information, see
LAN/VCG port density” (p. A-32) . Circuit packs that support multiple service modes For
more information about Ethernet circuit packs, see
“Ethernet/SAN circuit packs” (p. A-7) .
Private LAN
Private LAN service extends the concept of Private Line to connect more than two locations in an extended Ethernet LAN. This is accomplished by introducing embedded
Ethernet switching at each node. The SONET bandwidth is still dedicated to one subscriber. Because this is a switched service, the attendant QoS features are available.

Introduction to Ethernet services
....................................................................................................................................................................................................................................
VLAN tagging is an integral part of Private LAN service. VLANs are used to distinguish customers or organizations within customers. In the Transparent Mode, the service provider provisions a port tag, or customer ID, for each Ethernet port. This port tag is added to each incoming packet and carried with the Alcatel-Lucent 1665 DMX network in order to keep the traffic for each subscriber separate. When the packets exit the
Alcatel-Lucent 1665 DMX network, the port tag is removed. Any subscriber-inserted
VLAN tags within the packets are carried through the network unchanged.
In 802.1Q mode, the provider coordinates VLAN tags with the subscriber to further manage traffic flows. For example, some VLANs can limit traffic among particular groups of sites representing communities of interest while others may be used for traffic common to all. This can be coupled with QoS features such as PIR and priorities to optimize the Private LAN network. For more information about Quality of Service, see
“Quality of Service” (p. A-59) . For more information about Tagging modes, see
Virtual Private LAN
Virtual Private LAN service extends the concepts of Private LAN service to include bandwidth sharing among multiple customers. In this way, less SONET bandwidth can be used to serve customers by taking advantage of the efficiency of statistical multiplexing.
VLAN tags or port tags are used to keep each subscriber's traffic private.
Virtual Private Line
Virtual Private Line, a shared service between two points, is a special case of Virtual
Private LAN. It requires the use of Ethernet switching functions and is therefore configured and managed in the same way as Virtual Private LAN.
Network topologies and configurations
Network topologies consist of two layers: the packet layer and the underlying SONET layer. Packet networks can be created over a variety of SONET topologies, and have different properties as a result. For example, a Private Line service uses a point-to-point packet topology, but may be carried over a SONET ring, which may in turn be configured with UPSR protection or no SONET protection.
The following packet topologies are supported:
• Point-to-point
• Multipoint
• Hub-and-spoke.

....................................................................................................................................................................................................................................
Point-to-point
The point-to-point topology is used to join two nodes. For example, a business may connect to an ISP via a point-to-point connection. Because of its simplicity point-to-point configurations have a variety of protection options available. They may use any of the
SONET layer protection mechanisms. They may also forgo SONET protection and use data-layer protection such as Link Aggregation.
Multipoint
In a multipoint network all points converse with each other. Note that connecting three locations by two point-to-point connections is not the same as if done by a multipoint connection. The location in the middle of the point-to point connections would have to provide external switching to enable the outer locations to converse with each other.
One useful case of multipoint configurations is a packet ring. In a closed-ring configuration all nodes may converse. An internal spanning tree may be configured for protection and loop prevention. This is independent of any spanning tree protocol that may be running on the subscriber's network. The spanning tree breaks one link, necessary with a ring of interconnected bridges. In the case of a link failure, the spanning tree algorithm restores connectivity by moving its break to coincide with the failed link.
A special case of multipoint configuration is where one node acts as a hub and all other nodes converse only with it. This hub configuration differs from a hub-and-spoke network only in that the spokes share bandwidth to reach the hub. It is more efficient and may be more practical because it conserves hub ports; only two VCG (WAN) ports are needed, regardless of the number of spokes. (In a packet ring configuration the broken link is placed between the two nodes most remote from the hub; because those nodes don't converse, there is no loss of useful bandwidth.) Both this topology and the hub-and-spoke described next are sometimes called point-to-multipoint.
Hub-and-spoke
The hub-and-spoke network is a hybrid between point-to-point and multipoint. Each node connects to the hub via a dedicated link; but, the links terminate on an embedded switch at the hub. In a typical back-haul application, the switch aggregates the traffic into a single Ethernet link for hand off. As in the multipoint hub network, tags are used to identify and direct traffic to and from the hub.
Applications
Ethernet applications are examples of what users can do with the services and topologies described in previous sections. The user can be the owner of the equipment or a client of the owner. For example, an ISP can have a private network or buy the services from an
LEC to construct the application.

Alcatel-Lucent 1665 DMX supports the following applications:
• LAN interconnect
• LAN extension
• ISP access
• Internet access
• Video distribution
LAN interconnect
Two or more enterprise LANs are interconnected. The LANs may be point-to-point
Private Line connections, in which case Ethernet switching services are not provided. If
Virtual private lines are desired, Ethernet switching is required. Even so, in a three-node
LAN Interconnect application composed of Virtual private lines the middle node has two termination ports, one for each neighbor. This is different from a three-node LAN
Extension (next application) using Virtual Private LAN in which the middle node may have only one (effectively a hub) port.
LAN extension
Sometimes called intranet or Layer 2 VPN, this extends an enterprise LAN to multiple locations via embedded Ethernet switching. Either Private LAN or Virtual Private LAN may be used.
Transparent LAN is a common form of LAN Extension in which the subscriber's traffic is transported without regard to the presence of subscriber VLAN tags. Transparency is achieved by the use of Port Tags, avoiding the need for the provider to administer VLANs with subscribers. The Port Tag is effectively a customer ID; only ports in the network assigned a particular customer ID will exchange traffic.
In Non-Transparent LANs, greater flexibility is available when the subscriber's 802.1Q
tags are used for traffic management (802.1Q mode). For example, the priority bits within the tag can be used to give a portion of the traffic, for example VoIP, preferential treatment versus file transfer or other internet traffic. DSCP offers an alternative to priority bits. DSCP can also be used to give certain packets/data streams preferential treatment.
Although in a Virtual Private LAN service a Non-transparent LAN application requires the administration of VLAN Id's among customers, in a Private LAN where no other customers share the embedded Ethernet switch this is not necessary. For more information about priority bits, see
ISP Access
In this application an ISP uses a provider's network to collect internet traffic. It is also an example of a trunking application, where traffic from multiple customers is handed off to the ISP router on a single trunk link for efficiency. The Virtual Private LAN service may be used to efficiently transport the best-effort internet traffic. It is typically done using the

802.1Q mode for separating the ISP's clients' traffic. If the ISP's router supports stacked
VLANs then it can be done in Transparent Mode The trunk link may be GbE while the access links may be 10 or 100 Mb/s Ethernet.
Internet access
In this application the ISP owns the network. In this case the clients' traffic is untagged.
The ISP adds tags for customer separation using the 802.1Q mode. The ISP administers the tags directly, there is no third party involved.
Video distribution
Video distribution can be accomplished using Ethernet Multicasting. A Private LAN service is used to guarantee the bandwidth. Video traffic, generated at the head end, is sent using a multicast address. Transparent mode or 802.1Q mode may be used. At each node the traffic is dropped to its user and also duplicated and sent to the rest of the Private
LAN.
An alternative is to use SONET drop-and-continue cross-connections to implement multicasting. This is a variation of the Private LAN service. Although it is limited to one-way video distribution, it supports full line rate throughput.

Notes:
1.
With non-VLF Mains, most Ethernet and SAN pack can only occupy slot 1 of a FN or Growth group. Those packs that can occupy either slot are noted in the Description column. The unprotected LNW170 can occupy both slots with non-VLF Mains. In order to support all other Ethernet and SAN packs in both Slot 1 and 2 of a Function Group or Growth Slot, Alcatel-Lucent 1665 DMX must be equipped with VLF Mains
(LNW59/LNW82/LNW504).
2.
Alcatel-Lucent 1665 DMX does not allow installation of two packs with electrical interfaces in adjacent slots within the same Function Unit or Growth Slot. Therefore, in systems equipped with LNW59, LNW82, or
LNW504 VLF mains, LNW74 packs can reside in either Slot 1 or Slot 2 of a group, but not both at the same time. However, another optical (Ethernet or SONET) pack may be installed in the other slot.
4-port GbE-PL Private Line Fast Ethernet circuit pack (LNW63)
The GbE-PL Private Line Gigabit Ethernet (LNW63) circuit pack provides point-to-point
(Ethernet Private Line Service) data transport at the 1000 Mb/s rate. The GbE-PL circuit pack supports generic framing procedure (GFP) encapsulation and STS virtual concatenation.
The LNW63 circuit pack supports STS-1, STS-3c, STS-12c cross-connects. LNW63 has
4 VCGs, and each VCG can have up to 21 STS-1 tributaries and the total available backplane link space is 48 STS-1s to Main-1 and 48 STS-1s to Main-2. The tributaries may be assigned freely, all VCGs have access to all tributaries. See

The LNW73C differs from the LNW73 in that it enables compression of SAN traffic.
The LNW73C is able to compress asynchronous Fibre Channel traffic and conserve up to
50% of bandwidth versus uncompressed asynchronous FC traffic in typical applications.
Compression for asynchronous FC traffic is pre-standard and will be standardized by
FC-BB-4. The implementation of SAN compression enables a high throughput of up to two full-line rate FC-2G interfaces in a single pack.
The R6.0 implementation of SAN compression enables a high throughput of up to two full-line rate FC-2G interfaces in a single pack.
LNW73/73C packs can be placed in Slot 1 of any function group or growth slot in the shelf (A1–G1) and Alcatel-Lucent 1665 DMX supports a total add/drop capacity of 20
Private Line GbE ports if all slots are equipped with LNW73/73C circuit packs.
For detailed information about Ethernet technologies, see
“Ethernet transport” (p. A-20) .
When an LNW73 or LNW73C circuit pack occupies only 1 slot of a Function Unit group, the other slot must be populated with an apparatus blank.

Ethernet transport
Overview
An Alcatel-Lucent 1665 DMX network accepts Ethernet frames at an ingress port and transmits them out of one or more egress ports. The egress port(s) can be on the same network element or on a different network element. If it is on a different network element,

Ethernet frames are transmitted over a SONET network. To transport an Ethernet frame across the SONET network, the Ethernet Frame is moved between a LAN port and the
SONET network.

The following occurs to transport an Ethernet frame over a SONET network
• Alcatel-Lucent 1665 DMX accepts an Ethernet Frame at an ingress LAN Port.
• The Ethernet frame is accepted at an Ethernet switch's LAN port for switched services, processed, and then transmitted out one or more of its LAN and/or VCG
(WAN) port(s). For Private Line circuit packs that support only non-switched services, the Ethernet frame is sent directly to the GFP mapper via a VCG port.
• The generic framing procedure (GFP) mapper encapsulates the Ethernet frame into a
GFP Frame.

• The Virtual Concatenator maps the Ethernet stream into one or more SONET tributaries (time slots). This allows the network to carry traffic (Ethernet stream) at higher speeds than allowed by a single SONET tributaries (time slot). The group of virtually concatenated tributaries is referred to as a Virtual Concatenation Group
(VCG).
• The VCG is then placed on SONET tributaries and transmitted over the SONET network.
Generic framing procedure (GFP)
Generic Framing Procedure (GFP) is used to encapsulate Ethernet frames for transport over a SONET network. Alcatel-Lucent 1665 DMX uses frame-based GFP with the core header and no optional extension headers. The GFP Frame Check Sequence (FCS) is provisionable (on/off) on LNW63, LNW64, LNW87, LNW705 ports (
ed-eport
).

To encapsulate an Ethernet frame, the Ethernet preamble and Start of Frame Delimiter
(SFD) fields are removed from the frame. A Type header and check (tHEC) is added to the Ethernet frame creating a GFP payload. The GFP payload is then scrambled and a
Core header is added. The GFP frame is then sent to the Virtual Concatenator. The following figure shows the format of a GFP frame.

In the opposite direction when the GFP Mapper receives a GFP frame from the Virtual
Concatenator, it removes the Core Header and, using the cHEC field, performs a Header
Error Check. If the header is correct, the payload area of the GFP is then unscrambled and the Type field and tHEC in the GFP header are checked for correctness. The Ethernet frame is extracted and the Preamble and SFD are added.
The GFP mapper at the far end of the network inserts idle GFP frames when there are no
Ethernet frames to send. The near end GFP Mapper discards any idle GFP frames it receives over the SONET network. The idle GFP frames are not forwarded to the Ethernet
Switch. (Private line packs do not contain an Ethernet switch.)
The GFP Mapper contains GFP queues that are used to store Ethernet frames while they are being processed.
The Generic Framing Procedure is defined in ITU-T G.7041/Y.1303 and ANSI T1X1.105
Sections 7.3.2 and 7.3.3.
Virtual concatenation
Virtual Concatenation is a standard inverse multiplex scheme for transporting a payload using multiple channels each of which has a lower capacity than the payload to be transported. It allows finer granularity in allocating the transport bandwidth than is available in standard contiguous concatenation (STS-3c, STS-12c, STS-48c, STS-192c etc.). For example, an STS-1 tributary has a usable bandwidth of approximately 48.4
Mb/s. This is too slow for a 1 Gbits/s Ethernet stream. An STS-48c tributary has approximately 2.4 Gb/s which would waste 1.4 Gb/s of bandwidth if used to carry a 1
Gb/s Ethernet stream.
Using virtual concatenation, 21 STS-1 tributaries can be used providing an effective rate of approximately 1.02 Gb/s. Fewer STS-1 tributaries can be virtually concatenated to provide sub-rate (fractional rate) service.

The grouped SONET tributaries form a Virtual Concatenation Group (VCG). A VCG is treated as a single logical serial byte stream whose payload capacity equals that of the sum of the payload capacities of the constituent SONET tributaries. The following figure shows a virtual concatenation group.

MA-DMX-345
Individual tributaries in the VCG are independently transported through the SONET network. Only the initial and final SONET nodes perform the Virtual Concatenation.
Since the VCGs are invisible to the intermediate SONET nodes, the intermediate nodes only need to transport normal SONET traffic and do not need to understand VCGs. This allows the tributaries to be transported through equipment which does not handle VCGs.
Differential delay buffers
Because the individual tributaries of a virtual concatenation group (VCAT) can take different paths through the SONET network, they may experience different delays through the network.
The table below provides the differential delay buffers for each of the Ethernet circuit packs.

SONET transport
Ethernet circuit packs contain LAN ports and VCG ports. The LAN ports connect to external Ethernet equipment. The VCG ports connect to the OLIUs via Generic Framing
(GFP) Mappers and Virtual Concatenation Groups (VCGs).
The OLIUs contain the hardware that perform the SONET cross-connections and process traffic at the SONET tributary level. They do not know about the embedded Ethernet frames or Virtual Concatenation Groups.
Connections to the SONET network can be configured to provide SONET layer protection. Alcatel-Lucent 1665 DMX supports three types of SONET protection:
Unidirectional Path Switched Rings (UPSRs), Bidirectional Line Switched Rings
(BLSRs), and 1+1.
Alcatel-Lucent 1665 DMX supports transport of Ethernet frames on the following:
• UPSR tributaries
• Unswitched UPSR tributaries
• BLSR tributaries
• 1+1 point-to-point tributaries
• 0x1Sn tributaries
• Ethernet-to-Ethernet hairpin cross-connections

Protected tributaries
On protected tributaries, both rings carry the same traffic placed in the same tributaries
(time slots), but in opposite directions in the case of UPSR. UPSR protected cross-connections are provisioned as one 1wayPR cross-connections and two 1way cross-connections. BLSR protected cross-connections are provisioned using 1way cross-connections only.
Figure A-10 SONET protected cross-connections
For the LNW63, LNW64, LNW74, LNW87, LNW170, and LNW910 circuit packs, all
VCG ports can be used and all ports are supported regardless of STS mode. The picture above depicts the LNW74 and LNW170 in Private Line mode. The LNW170 can also function in switched mode. For figures depicting the LNW170 in switched mode, see
Figure A-11, “Multi-point cross-connections (unprotected)” (p. A-28)
and/or
“LNW170 Gigabit multipoint cross-connections (unprotected)” (p. A-29) .
Unprotected tributaries
In the case of UPSR unprotected tributaries, the two sides of the ring carry different traffic. Each VCG is connected to only one side of the ring.
1-way unswitched cross-connections provide unprotected SONET connections to
Ethernet circuit packs on a UPSR. On BLSR w/NUT, only 1way cross-connections are used. Each can be used to form two individual connections. One VCG is connected to
MAIN 1 while the other VCG is connected to Main 2.

On the LNW74 circuit packs, the odd number VCGs are paired with the next higher number VCG (VCG 1 is paired with VCG 2, and VCG 3 is paired with VCG 4.) For example, VCG 2 must be connected to one OLIU when VCG 1 is provisioned to be connected to the other OLIU. Both cross-connections use the same SONET tributaries.
The following figure shows an example of the VCG port pairing.

Multipoint cross-connections can either be used as two unprotected point-to-point connections or as part of a packet ring. If they are used as part of a packet ring, the
Ethernet switch will process traffic received on one side of the packet ring before it is forwarded out the other side of the ring.
On the LNW63, LNW64, LNW74, LNW87, LNW170, and LNW910, any VCG can be connected to any OLIU. Additionally, the pairing of VCG ports for multipoint applications is not fixed.

Ethernet-to-Ethernet hairpin cross-connections
Ethernet-to-Ethernet hairpin cross-connections are used to connect a circuit pack to another circuit pack within the same Alcatel-Lucent 1665 DMX. The cross-connection goes through either Main 1 or Main 2, but not over the SONET ring.
Hairpin cross-connections with an Ethernet circuit pack are used to either connect a VCG on that circuit pack with a VCG on another circuit pack or to connect a VCG with an
OLIU located in a function or growth slot. Hairpin connections between VCG ports are

Ethernet LAN/VCG port density
The Ethernet Switch, also referred to as a Media Access Control (802.1D MAC) bridge, processes the Ethernet frames and handles Virtual LANs, frame priority, frame forwarding, and switching functions. The ports on the customer's side of the switch are referred to as LAN ports, and the ports on the SONET side are referred to as VCG or
WAN Ports.

Virtual LANs (VLANs)
A virtual LAN (VLAN) is a logical grouping of LAN ports, possibly spread across multiple Alcatel-Lucent 1665 DMX nodes, that act as if they comprise a single LAN.
Since a physical LAN can be associated with multiple virtual LANs, VLANs can be used to segregate traffic across a network. VLANs can be used to segregate different types of traffic for a single customer or to separate traffic belonging to multiple subscribers.
VLANs operate at the Ethernet (MAC) Layer. This allows different VLANs to be carried on the same physical media and hides the VLANs from higher-level protocols (for example, TCP and IP). The higher-level protocols treat each VLAN as if it was a separate physical LAN. VLAN-aware Ethernet Switches will forward VLAN traffic only on ports assigned to that VLAN. A port can be part of several VLANs and a VLAN can be assigned to several ports.

A frame's VLAN can be assigned either by the subscriber's equipment or by network equipment. User equipment specifies the VLAN by including a VLAN Tag in the frame.
Alcatel-Lucent 1665 DMX determines a frame's VLAN either from the frame's existing
VLAN Tag or by the default VLAN ID assigned to the frame's ingress port.
Alcatel-Lucent 1665 DMX can be provisioned to drop frames that do not contain a tag.
VLAN tags
VLAN Tags are located in the Ethernet Header. The following figure shows the format of
Ethernet frames without a VLAN Tag, frames with a VLAN Tag, and the format of the
VLAN Tag.

Alcatel-Lucent 1665 DMX supports provisioning of 4093 VLAN IDs within the range of
1–4093. Additional information about VLAN tags can be found in IEEE 802.1Q.

In order to allow carriers to administer VLAN IDs independent of their subscribers,
Alcatel-Lucent 1665 DMX can be provisioned to add a second VLAN Tag to Ethernet
Frames. This tag, referred to as a Port Tag or Stacked VLAN Tag, can be used by the service provider to identify and segregate customer (subscriber) traffic. The following figure shows the format of an Ethernet frame that contains stacked VLAN tags.

The port tag is formatted according to IEEE 802.1Q except:
• The frame is given a provisioned Ethertype (TPID).
• The Canonical Format Indicator (CFI) field is set to 0.
• A Customer ID is encoded into VLAN ID field and can contain a value in the range of
1–4093.
Alcatel-Lucent 1665 DMX is capable of handling frames with multiple layers of VLAN tags; ultimately the limit is that frames greater than the MTU size are rejected as too large. When processing VLAN tags, Alcatel-Lucent 1665 DMX only looks at the outermost tag (that is, the one that most closely follows the Source Address) that it recognizes. Recognition of a tag is based on the TPID value. In 802.1Q mode, the expected TPID value is 8100hex. In transparent mode, the expected TPID value is provisioned by the user, with the default value being FFFFhex. Legal provisioned values for TPID are between 0601hex and FFFFhex. These TPID values are also used to identify any tags inserted by Alcatel-Lucent 1665 DMX.

Based on provisioning at the network ingress and egress points, it is possible for an
Ethernet frame to enter and leave the network with a different number of VLAN tags.
Priorities
Each Ethernet frame is assigned a priority level. The priority level can be based on a field in a VLAN Tag or a default priority assigned to the frame's ingress port. If an ingress port is provisioned with a default priority, the default priority will take precedence over the priority field in the VLAN tag.
A VLAN Tag contains a three-bit user_priority field. This allows higher priority frames to be processed at a faster rate than lower priority frames. The LNW170 packs contains 4 priority queues. For more information about the LNW170, see
For tagged frames, the following table shows the mapping between values in the user priority field and the priority queues for all of the Ethernet packs except the LNW170. An
Ethernet port can be provisioned to drop untagged frames, or add a VLAN tag containing the port’s default user priority field value of 0 (low) or 7 (high).

Ethernet bridge/switch
An Ethernet bridge moves a frame from an ingress port to an egress port(s). It will not forward a frame if the frame contains errors or has the same source and destination addresses.
The bridge looks up the destination MAC address/VLAN ID combination in the address table. If the MAC address is found, the bridge sends the frame to the port(s) found in the address table. If the MAC address is not found, the bridge sends the frame to all ports associated with the VLAN ID (except the originating port).
All multicast and broadcast frames are broadcast, including spanning tree BPDUs.
The size of the address table is 256K for the LNW170 packs. Each combination of MAC
Address/VLAN ID is one entry. Entries are removed if they are not used within 300–600 seconds (5–10) minutes. During a topology change, they are deleted as soon as the change is detected.
The size of the address table is 32K for the LNW910 packs.
Virtual switch
The single physical Ethernet switch on an LNW170 Ethernet circuit pack can be logically divided into multiple virtual switches. A virtual switch, identified by an id number between 1 and 16 on LNW170, consists of a collection of LAN and VCG ports.
The LNW910 supports a single virtual switch.
Any VLANs and spanning tree groups associated with the ports also become associated with the virtual switch. Each LAN port, VCG port, VLAN ID and spanning tree group id can only be associated with one virtual switch per Ethernet circuit pack. On the LNW170, the same VLAN ID can be associated with many virtual switches and each virtual switch has its own VLAN ID. A minimum of one virtual switch must be created on the LNW170
Ethernet circuit pack in order to provision VLANs and spanning tree groups when in
802.1Q or Transparent Tagging mode. When a port is removed from a virtual switch it returns to its default parameters. Virtual switches are not used in Private Line mode or on
LNW74 circuit packs.

The following figure shows one possible assignment of LAN ports and VCG ports into virtual switches. The figure shows one physical switch that is divided into two virtual switches. Virtual switch 1 supports a packet ring configuration encompassing LAN port 1 and VCG ports 1 and 2. Virtual Switch 2 supports a point-to-point configuration encompassing LAN port 2 and VCG ports 1 and 2. Ethernet traffic will not be allowed to cross between the virtual switches.

Spanning tree protocol (STP)
Spanning tree protocol (STP) provides a protection scheme for Ethernet packet transmission as a by-product of its primary function of eliminating loops in Ethernet networks. This protection is independent of any SONET-level protection mechanisms such as UPSR switching. In fact, undesirable interactions can occur if both protection mechanisms are used, so it is recommended that spanning tree protocol be used only in configurations with no SONET protection.
Loops can arise within Ethernet networks as a result of multiple paths between a source and a destination. The spanning tree protocol identifies links that must be blocked to ensure that no such multiple paths can exist. Any link failure in the resulting network triggers the spanning tree protocol to analyze the network and identify a new set of blocked links that provide full connectivity with no duplicated paths. It is this reconfiguration in response to failures that constitutes the packet layer protection mechanism.

How it works
Spanning tree works as follows:
1. Initially, every node in the group thinks it is the root node.
2. Configuration BPDUs are sent from each node to determine the most economical route from each node to the root node.
3. As information about the network becomes clear, one node is designated the root node; from this node, the distance to any point in the network may be measured.
4. Once the network has become clear, some ports are blocked so that there are no loops in the network and so that the network provides the most efficient paths from the root to the nodes. This effectively creates a tree structure for the network.
5. If an active link fails, the network is reconfigured so that previously blocked links can be used for traffic.

Important! The configuration provides the least (most efficient) path from each node to the root. The configuration also provides only one path between any two nodes.
Reconfiguration
If one of the active links is broken, the network reconfigures to activate the inactive link.
For example, if the link between 2 and 3 is broken, the link between 5 and 7 would be enabled.

802.1W rapid spanning tree protocol
The 802.1W rapid spanning tree protocol (RSTP) improves upon the 802.1D version of spanning tree protocol. The key improvements are:
• Faster Failure Detection - Alcatel-Lucent 1665 DMX uses SONET-layer failure detection to trigger packet-layer (spanning tree) reconfiguration, so packet-layer reconfiguration starts within a few milliseconds after a failure rather than several seconds later.
• IEEE 802.1W Rapid Reconfiguration - Alcatel-Lucent 1665 DMX supports standard packet-layer restoration protocol, which uses messages between spanning tree protocol entities to significantly reduce convergence time.
• Spanning tree version interworking - Each Alcatel-Lucent 1665 DMX node will query its Ethernet link partners to determine if they are capable of running the 802.1W rapid spanning tree protocol. If so, the 802.1W protocol will be used. If not, Alcatel-Lucent
1665 DMX will fall back to running the 802.1D version of spanning tree protocol.
• Enhanced STP configuration reports and controls - Together with 802.1W, these enable support for much larger networks than are supported with IEEE 802.1D
Spanning Tree Protocol.
Spanning tree on LAN ports
Alcatel-Lucent 1665 DMX supports spanning tree on the LAN (customer facing) ports.
STP on LAN ports ensures that single LAN interconnects are protected. Because redundant LAN interconnects create loops, STP manages the loops. STP is supported on the LAN ports of the LNW170 only.
Both LAN ports and VCGs can belong to STP groups. A LAN port can belong to only one STP group at a time. The BDPU VLAN ID is provisionable on a per-port basis.

Link aggregation
Alcatel-Lucent 1665 DMX supports link aggregation on any two LNW170 LAN ports of the same rate (i.e. 100 or 1000 Mbps), operating in switched mode. The LNW170 supports LAGs that span LNW170 packs.
LAG is also supported on the LNW910 pack. In unprotected mode, LAGs can be created from 2 FE/GE ports on the pack. In protected mode, LAGs are automatically created for ports 1–10. If required, the user can provision a LAG on port 11 (10GbE port).
Refer to
for more information.
Flow control
This section describes how Alcatel-Lucent 1665 DMX controls the flow of Ethernet traffic. Alcatel-Lucent 1665 DMX supports the following types of flow control:
• Local flow control
• End-to-end flow control
Prior to Release 9.1, the software sets the buffer size and flow control thresholds based on the MTU and flow control provisioning (enable or disable/drop.) Beginning in Release
9.1, the automatic buffer size provisioning is decoupled from the MTU and flow control provisioning on the LNW63, LNW74 and LNW170 (private line applications only).

....................................................................................................................................................................................................................................
Using the existing queue size parameters (qsz), in the ED-EPORT and ED-VCG commands, the user can optionally provision the buffer size independently of the mtu size
(mtu_size) and flow control mode (fcmd).
On the LNW910, there is no need to provision the buffer size since there is a buffer pool that is shared by all the ports.
Beginning in Release 9.1, ports on the LNW63 and LNW74 support the following values for total queue size. These values also apply to the LNW170 VCGs when in private line mode.
• NA (default) Not Applicable. The ingress queue size is automatically set as a function of mtu_size and fcmd, consistent with releases prior to Release 9.1
• 128 The ingress queue size is 128 Kbytes. This value is supported for FE ports only.
• 512 The ingress queue size is 512 Kbytes. This value is supported for GE ports only.
Local flow control (ingress traffic direction)
If the external equipment delivers Ethernet frames to the Ethernet circuit pack faster than they can be delivered across the network, the data buffers in the Ethernet circuit pack fill up. When the data buffers reach the flow control threshold, the Ethernet circuit pack initiates flow control. On full duplex links, the Ethernet circuit pack issues a flow control request to the external equipment, requesting that the flow of frames be suspended. On half duplex links, the JAM signal is used to stop all traffic. The flow control request is repeated periodically, or the JAM signal continuously generated until the buffers empty sufficiently.

Note that this local flow control mechanism is concerned only with congestion (full packet buffers) at the local Alcatel-Lucent 1665 DMX. If the Alcatel-Lucent 1665 DMX at the other end of the SONET network is unable to deliver the Ethernet frames to the attached external equipment due to flow control conditions there, that does not directly affect the local flow control operation at the ingress Alcatel-Lucent 1665 DMX.
Local flow control (egress traffic direction)
If the local Ethernet circuit pack attempts to deliver Ethernet frames to the attached external equipment faster than the external equipment can accept them, the external equipment may initiate flow control. On full duplex links, the external equipment issues a flow control request to the Ethernet circuit pack requesting that the flow of frames be suspended. On half duplex links, the JAM signal is used to stop all traffic.

This causes the Ethernet circuit pack to stop sending Ethernet frames to the external equipment for the time requested in the flow control request. During this time, Ethernet frames accumulate in the packet buffers in the Ethernet circuit pack. Once these buffers fill completely, further Ethernet frames arriving from the SONET network for the egress
Ethernet port are dropped.
End-to-end flow control
If the external equipment at the destination of an Ethernet connection cannot handle the rate of traffic being sent to it, it may be desirable to apply back pressure across the network to slow down the external source of the Ethernet traffic. This cross-network back

pressure can only work well, however, when the source of the traffic can be identified unambiguously. Only the Ethernet Private Line Service offers this opportunity; thus, it is the only service that supports End-to-End Flow Control.
End-to-end flow control (LNW63/170 circuit pack)
The LNW63/170 circuit pack implements the following changes intended to improve the frame loss behavior of end-to-end flow control.
• When provisioned for end-to-end flow control, the LNW63/170 circuit pack sends a flow control request across the SONET network immediately upon receiving a flow control request from external equipment.
• The LNW63/170 circuit packs contain large latency buffers to hold data while waiting for far-end equipment to respond to end-to-end flow control requests.
Figure A-22 End-to-end flow control (LNW63/170 example)
After a flow control request is received, the LNW63/170 circuit pack buffers frames instead of sending them to the equipment that generated the flow control request. Each port has its own latency buffer. A latency buffer can store 16ms of traffic that allows the equipment to be about 1000 miles apart (2000 miles round trip).

Physical interface
Each Ethernet circuit pack contains a transceiver that implements the physical interface for that circuit pack's line type. For the 10/100 Mbps circuit packs, this physical interface must be provisioned to or auto-negotiate to the proper line rate and duplex mode in order to communicate successfully with the connected equipment. Gigabit Ethernet interfaces only support the 1000 Mbps line rate and full duplex mode, so this is not an issue for these circuit packs. All optical 100BASE-X interfaces support the 100 Mbps line rate only.
At the physical layer, many types of LANs can be used for multiple line rates and duplex modes. For example the LAN port on most PCs can be connected to a 10BASE-T (10
Mbps) or a 100BASE-T (100 Mbps) LAN. Before data traffic can be transmitted onto a
LAN, all ports connected to the LAN must operate with the same line rate and duplex mode. LAN ports can either be provisioned with these values or provisioned to automatically negotiate (auto-negotiate) the values.

Auto-negotiation
In the auto-negotiation process, a LAN port advertises its acceptable parameters, compares these with the advertised parameters of its link partner, and then agrees upon a set of parameters with the link partner. IEEE 802.3 allows the line rate, duplex mode, and flow control mode to be auto-negotiated. A LAN port not configured to support auto-negotiation will use provisioned values for these parameters. A LAN port configured for auto-negotiation that is connected to a LAN port not configured for auto-negotiation will follow prescribed rules for parameter settings.
On connected Gigabit Ethernet ports with auto-negotiation enabled, if transmission is interrupted in one direction of transmission on a Gigabit Ethernet port, then transmission is disabled in the other direction. For example, if one fiber in the transmit/receive pair is cut, then one-way transmission on the other fiber is maintained only if auto-negotiate is disabled and the link state is forced good at the transmit source equipment.

Notes:
1.
Flow control will only be enabled if the connected equipment is capable of Symmetric Flow Control.
2.
IEEE 802.3 does not define flow control states for half duplex links or when only one side of a link is provisioned for auto-negotiation. This is the expected behavior of the connected equipment.
3.
IEEE 802.3 recommends that equipment be configured for auto-negotiation to avoid inconsistent provisioning.
Important! Flow control on all optical Fast Ethernet ports must be provisioned manually.

Queues and buffers
Ethernet circuit packs contain small buffer pools that provide storage of Ethernet frames for brief periods of congestion or until flow control requests can be honored. These small buffer pools are associated with the Ethernet switch and the Generic Framing Procedure
(GFP) mechanism. The GFP mechanism is described further in
for individual STS-1s is associated with the virtual concatenation process. Its function is described in more detail in
“Virtual concatenation” (p. A-24) . The LNW170 provides 4
priority queues. For more information, see
“Metering (CIR and PIR)” (p. A-68) .
LNW63/64/74/170 circuit pack buffers
In Private Line Mode, the Ethernet frame buffers are all associated with the Generic
Framing Procedure (GFP) and virtual concatenation mechanisms. The following table shows the LNW63/64/74/170 circuit pack buffers.

The LNW63/64/74/170 circuit packs provide larger buffers to allow for longer response times to flow control requests. In addition, buffer storage can be flexibly assigned to
Ethernet frames, allowing maximal usage of the memory available.
Note: For additional information on differential delay buffers, see
“Differential delay buffers” (p. A-25) .
LNW910 circuit pack buffers
For LNW910 circuit pack, there is no need to provision the buffer size. Instead, there is a buffer pool that is shared by all ports; it is not partitioned on port by port basis. However the buffer pool provides the same benefit of protecting an individual port from “bursts”.

Tagging Modes

Tagging Modes
Overview
Alcatel-Lucent 1665 DMX supports the following tagging modes.
• Private line mode (also know as no tag or repeater mode)
• Switched mode
• 802.1Q mode
• Transparent mode.
The tagging mode is user provisionable on a circuit pack basis. Different circuit packs on a single Alcatel-Lucent 1665 DMX shelf can be provisioned for different modes but, all ports on a circuit pack must use the same mode.
Private line mode
The Private Line mode (also known as no tag or repeater mode) is used to establish simple point-to-point connections between two ports with no Ethernet switching functions applied. No additional Ethernet provisioning is required after the cross-connection is established. Private line mode can be used to provide either a full rate or sub-rate
(fractional rate) dedicated Ethernet link across SONET networks. No preferential treatment for high priority packets is provided. In a sub-rate service, frames may be dropped due to congestion. Any correctly formatted Ethernet frame received at a source port is transmitted out of the destination port.
The Private Line mode supports the following features:
• Point-to-point topology with only two LAN ports
• MAC address filtering is enabled (not available for LNW74)
• Protection is provided at the SONET network layer by either UPSR switching
• No spanning tree protocol (supports transparency of customer spanning tree protocol)
• No VLAN ingress filtering or classification (VLAN tags are not verified or added)
• Ethernet PM per port
For packet size info, see
“Packet size in different tagging modes” (p. A-58) .
Switched mode
Switched mode allows 802.1Q or Transparent mode to be selected based on a virtual switch (grouping of ports) and Pack equippage. For more information, see
“QoS services (LNW170)” (p. A-59) .

802.1Q VLAN mode
In 802.1Q Mode, a circuit pack can be provisioned to use an incoming frame's VLAN tag, to add a VLAN tag associated with the port for untagged frames, or to drop an incoming frame if its VLAN tagging does not meet provisioned specifications. The priority bits in an incoming frame's VLAN tag can also be used to affect the handling of the frame.
The following table summarizes the 802.1Q Mode VLAN ID and Frame Priority Rules.

A VLAN ID can only be assigned to one virtual switch on a circuit pack.
On the LNW170/78, the same VLAN ID can be assigned to different virtual switches on the same pack.
When using the 802.1Q mode, a service provider must coordinate (specify) the use of
VLAN IDs with customers. If a VLAN ID is assigned to more than one customer, the customers could receive each others traffic.
In Alcatel-Lucent 1665 DMX, the VLAN ID may be a numerical value in the range
1–4093.

If a port has been provisioned with a default VLAN ID for untagged frames, all incoming untagged frames (this includes frames containing a VLAN tag with a TPID value other than 8100hex) will have VLAN tag added with the default VLAN ID. Any frame exiting the Alcatel-Lucent 1665 DMX network tagged with the default VLAN ID will have its
VLAN tag removed before the frame is sent out the LAN port. Thus, assuming symmetric provisioning at the network edges, frames that enter the Alcatel-Lucent 1665 DMX network untagged will leave untagged as well.
Frames that enter the network carrying a standard 802.1Q VLAN tag (identified with a
TPID value of 8100hex) have their VLAN ID checked against a VLAN list for the entry port. If a match is found, the frame is admitted; otherwise, the frame is discarded. On exiting the network, customer-tagged frames are delivered with the customer-provided
VLAN tag intact unless it matches the default VLAN ID for the exiting port. In such a case, the customer-provided VLAN tag is removed before the frame is delivered.
The following figure shows the end-to-end frame processing combinations considering the following:
• Incoming frame tagging
• Default VLAN ID provisioning for source LAN port
• Default VLAN ID provisioning for destination LAN port

If VLAN tags are used, the ports support a maximum packet size of 1536 bytes (10236 for LNW170). If VLAN tags are not used, the ports support a maximum packet size of
1532 bytes (10240 for LNW170).
The LNW170 circuit packs support the 802.1Q mode.
Important! After the VLAN ID is provisioned for untagged incoming Ethernet frames and service is established in the 802.1Q mode, changing the VLAN ID may affect service. When the VLAN ID for untagged incoming Ethernet frames is changed at one point in the network, the VLAN ID must be changed at all points. If the VLAN
IDs are different, service is affected.
Transparent mode
In Transparent Mode, port tags (which are actually VLAN tags with a provisionable TPID value) are used to separate traffic for different customers. A port tag is added to each incoming frame at the ingress LAN port. The port tag contains a provisionable customer
ID and priority level.

The port tag, along with the destination MAC address, is used in switching the Ethernet frame to its correct destination. Assuming the destination port is also provisioned for
Transparent Mode, the port tag is removed as the frame is delivered out the destination port.
When using the Transparent Mode, service providers usually assign one customer ID to each customer LAN port. The service provider need not coordinate the selection of this customer ID with the customer since it is independent of any 802.1Q VLAN tags generated by the customer. Customers can use any VLAN ID they want without interfering with any other customer carried on the service provider's network.
In the transparent mode, the ports support a maximum packet size of 10240 bytes
(LNW170).
The LNW170 and LNW910 circuit packs support the transparent mode. The LNW74 circuit packs do not support the transparent mode.
The following figure shows end-to-end frame processing combinations considering the following:
• Provisionable TPID value set to its default value (0xFFFF)
• Incoming frame tagging
• Default port tag provisioning for the source LAN port
• Port tag provisioning for the destination LAN port.

TPID provisioning and tag list provisioning
The value of the TPID (Ethertype) parameter used with generated VLAN Tags can be provisioned (in transparent mode only). Also, the user may provision a list of acceptable customer tags for a LAN port. This pair of features allows Alcatel-Lucent 1665 DMX to interoperate with other equipment that supports stacked VLANs.

Quality of Service
Overview
Alcatel-Lucent 1665 DMX supports the following Quality of Service (QoS) capabilities:
• Private line service provides dedicated bandwidth between two points service (best
QoS).
• Fractional rate services provide basic rate control with SONET tributary granularity.
• Committed information rate (CIR) policing provides rate limiting with 1 Mbps granularity.
• Peak information rate (PIR) policing provides rate limiting with 1 Mbps granularity.
• LNW170 enables advanced QoS capabilities including CIR rate metering.
For detailed information about Ethernet frame priority levels, see
and
“802.1Q VLAN mode” (p. A-53) .
QoS services (LNW74)
The LNW74 circuit packs provide 10 Mbps and 100 Mbps Private Line services. They do not contain an Ethernet Switch. Each LAN port is connected to its own VCG. 100 Mbps traffic can be rate-limited by provisioning less SONET bandwidth than required to carry the full line rate. Traffic is buffered and flow control is invoked when ingress traffic on a
LAN port exceeds the VCG's SONET bandwidth. If flow control is disabled or ignored by the external equipment, Ethernet frames are dropped when the ingress buffer overflows. The LNW74 offers 1.5Mbps VT granularity.
QoS services (LNW170)
The capabilities of the LNW170 enable enhanced QoS features. The LNW170 can function in either Private Line or Switched mode.
The QoS capabilities of the LNW170 are different depending on the mode the card is in.
Also, within the two modes below, there are a variety of traffic conditioners which can be applied, depending on the mode) which further govern the QoS capabilities of the pack.
• Private Line: Alcatel-Lucent 1665 DMX can perform rate controlling at a sub-STS level and on a per-port basis in PL mode. In PL mode, if rate control is desired, the traffic management mode will be port mode (see Traffic Conditioners below).
• Switched Mode: Alcatel-Lucent 1665 DMX can perform VLAN processing and enhanced QoS in switched mode. There are two settings within switched mode:
Transparent and IEEE 802.1q mode. See
In order to provide enhanced QoS services, traffic must be classified, and conditioned.
This is accomplished using traffic conditioners that are applied to packets at the boundary port (see Boundary vs. Interior Port below).

....................................................................................................................................................................................................................................
Traffic Management Mode
The QoS features available on any given port will vary depending on the particular traffic conditioners applied to that port. The 5 traffic conditioners supported by Alcatel-Lucent
1665 DMX are as follows:
• PORT mode: One traffic conditioner for the port. All traffic that is permitted to be transported flows through a single traffic conditioner.
• COSPORT mode: One traffic conditioner for each class of service at the port. All traffic for an individual CoS is provisioned with its own traffic conditioner.
• TAGPORT mode: One traffic conditioner for each Packet Tag at the port. Traffic for all classes of service that have the same Packet Tag flow through a single traffic conditioner.
• COSTAGPORT mode: One traffic conditioner for each class of service for each
Packet Tag/VLAN at the port. All traffic for an individual CoS on each Packet Tag is provisioned with its own traffic conditioner.
• NOTC mode: In this mode all traffic is bridged through the switch as usual but there is no traffic conditioning performed on the traffic. NOTC mode emulates the (basic)
QoS behavior on the older Alcatel-Lucent 1665 DMX circuit packs (user_priority values 0,1,2 and 3 are mapped to CoS 0 and user_priority values 4,5,6 and 7 are mapped to CoS 3; no modification of user_priority bits in user packets).
Boundary versus interior ports
When speaking of QoS, a port is either a Boundary or Interior port. A boundary port is at the edge of a differentiated services (DiffServ) domain and an Interior port in a the core of a DiffServ domain. All traffic policing, conditioning, and marking is done at boundary ports. It is assumed that these functions have been performed by the time packets reach the interior ports. Boundary/Interior demarcation is controlled by an explicit parameter.
By way of provisioning, a LAN port or VCG can be either boundary or interior. A LAN port is usually (and by default) a boundary port, and a VCG is usually (and by default) an interior port.
QoS functionality is built around the concept of boundary and interior ports. Though the terminology customer and network are often used in place of boundary and interior
(where customer equals boundary and interior equals network), this is incorrect with reference to Alcatel-Lucent 1665 DMX. However, customer and network terminology is still applied to ports with respect to their overall VLAN tagging behavior, rather than QoS specific functions.

The table below explains what happens at the ingress when untagged or unconditioned packets are received. If a packet arrives at a port and it is marked with a CoS and Packet
Tag for which a traffic conditioner has not been provisioned at that particular port, the traffic is handled as described in the table below.

QoS in Private Line mode
Private Line mode should be employed when deploying point-to-point service connections using dedicated resources. Private Line can either be a full-rate service or a sub-rate service. Full-rate services dedicate enough network resources to transport the data from the ingress Boundary Port through the network to the egress Boundary Port at the full data rate of the Boundary Ports. Sub-rate services transport data at a fraction of the full data rate of the Boundary Ports.
In Private Line Mode, the Boundary Ports (see Boundary vs. Interior Ports above) can have either NOTC or PORT traffic management mode; the Interior Ports are always
NOTC. All packets received are handled uniformly using a single queue. Packets are not modified or remarked in this mode. Therefore, it is not possible to encode color.
Consequently, packets are either dropped or passed-through transparently. This is achieved by setting CIR values equal to PIR values and by forcing CBS to equal PBS.

QoS in transparent and 802.1q mode
Transparent mode provides a trunked Private Line or "Virtual Private LAN" service. The
Boundary Ports use either a NOTC or PORT traffic management mode. In transparent mode, customers packets are not changed.
In NOTC mode, just as with Private Line, there is no traffic conditioning performed on any of the boundary Ports. Traffic conditioning is never performed on the Interior ports.
In the PORT mode all traffic that enters the port is tagged (stacked VLAN) with the provisioned TPID and the default port tag. The CoS is set to the default priority for that port and the user_priority is set based on this CoS and the conformance level determined in the traffic conditioner.
Packets that are within the committed contract parameters are marked with a Drop
Precedence of DP1 (green). Packets that arrive out of the guaranteed contract, but within some allowable excess, are marked with a Drop Precedence of DP0 (yellow). Packets that arrive outside of the allowed excess are discarded.
The user_priority is determined from the CoS level and Drop Precedence. The packet is remarked with this user_priority before leaving the egress port.
In both NOTC and PORT mode, if no default priority is specified for the port, the CoS value is set to 0. There is no traffic conditioning on Interior Ports (see Boundary vs.
Interior Ports above).
With Transparent tagging, both PIR, CIR, PBS and CBS are used to allocate the appropriate network resources to each service. Transparent mode supports user network configurations with more than two nodes in case a multipoint "Virtual Private LAN" service is needed. For this service each Boundary Port is provisioned with the same default port tag and default priority. This results in the required traffic separation to provide a virtual private network.
802.1q mode
The 802.1TAG tagging mode assumes that packets arrive at the boundary to the network already tagged with a standards-compliant VLAN tag. It is possible then to offer a number of services at a single port simultaneously.
In 802.1q mode, the packets should be tagged by the subscriber, however, some packets may arrive untagged. The CoS level for tagged packets is determined either by the default port CoS level (PORT mode) or the default VLAN CoS level (TAGPORT mode), or by examining the user_priority and setting the CoS according to a fixed mapping (NOTC and PORT mode), or according to a provisionable mapping table. The mapping table is associated either with a port (COSPORT mode) or a VLAN (COSTAGPORT mode).
Untagged traffic is tagged with the default VLAN. The CoS is then set to either the default port CoS level (NOTC, PORT, COSPORT mode) or the default VLAN CoS level
(TAGPORT, COSTAGPORT mode). The packets are then conditioned (except for NOTC) in the same fashion as tagged traffic.

Priority-tagged traffic is tagged with the default VLAN, and the CoS level is determined as it would be for a tagged packet.
In all cases, the Drop Precedence (DP) is set according to the level of conformance specified in the customer's SLA contract.
The functionality of each traffic management with regard to 802.1q mode is detailed below:
• PORT: The PORT mode of operation, is very similar to the services offered in the
Transparent tagging mode, except that in this case the standard TPID (Ethertype) of
8100 is used so that this mode is interoperable with other 802.3 networks. Also more than one VLANid can be supported at a single port and treated as a single traffic flow.
In this mode the traffic conditioning for all traffic that is admitted to the port is performed as an aggregate data flow by a single traffic conditioner. Only traffic that is either untagged or tagged with a VLANid that has been provisioned at the port is admitted. In this mode the user_priority bits are remarked according to the user_priority (0,1,2,3 map to CoS 0 and 4,5,6,7 map to CoS 3) of the packets unless overruled by the default priority. Drop Precedence is determined as a result of the packets conformance to the SLA. Any remarking that occurs is irreversible and is present on the packet at the network egress.
• TAGPORT: In the TAGPORT mode of operation, a single CoS is associated with each
VLAN. The traffic flows through a traffic conditioner per VLAN where it is metered and policed as per the terms of the SLA. In this mode each VLAN has its own PIR,
CIR, PBS and CBS. Packets that arrive untagged are tagged with the port default
VLANid and CoS for that VLAN. As with the other modes, the Drop Precedence is determined based on the conformance to the SLA. Any remarking that occurs is irreversible and is present on the packet at the network egress.
• COSTAGPORT: In the COSTAGPORT mode of operation, traffic for each CoS on each VLAN flows through its own traffic conditioner. Traffic that is tagged with one of the port's provisioned VLANids is admitted to the network. Packets that arrive untagged or priority-tagged are tagged with the port default VLANid. Packets tagged with an unprovisioned VLANid are discarded. The user_priority bits in a priority-tagged frame are used to determine the CoS when selecting the traffic conditioner. In this mode each CoS on each VLAN has its own PIR, CIR, PBS and
CBS. On each VLAN each CoS can be individually enabled or disabled. The Drop
Precedence is determined by the SLA conformance level and the packet is remarked accordingly. This marking is not reversible and is present when the packet egresses the network.
• COSPORT: In the COSPORT mode of operation, traffic for each class of service flows through its own traffic conditioner. Traffic that is tagged with one of the port's provisioned VLANids is admitted to the network. Packets that arrive untagged or priority-tagged are tagged with the port default VLANid. Packets tagged with an unprovisioned VLANid are discarded. The user_priority bits in a priority-tagged

The table below shows the default mapping of DSCP to CoS. Alcatel-Lucent 1665 DMX supports DSCP for traffic classification on the LNW170. DSCP to CoS is available in
PORT mode only. DSCP can be used as an alternative to priority bits. The criteria for traffic classification can be user priority bits, DSCP, VLANid, or default value. DSCP allows for three differentiated services code point values: IP precedence value (also called
Class Selector-- CS in the table below), Assured Forwarding (AF), and Expedited
Forwarding (EF).

The number of services at a port is the number of traffic conditioners used, except for the NOTC mode where there is 1 service with no traffic conditioner.
2.
The number of services on a network is the total number of separate VLANids/default port tags allowed on the network in separate services times the number of traffic conditioners that are allowed for each
VLANid/default port tag.
3.
The maximum number of Classes of Service supported is the number that will be passed through any traffic conditioner on that port. For example, in 802.1TAG mode the PORT mode will allow all 4 CoS Levels to pass through a common traffic conditioner, whereas, in Transparent mode the PORT mode tags all traffic with the default CoS and therefore only a single CoS is supported.
4.
The traffic conditioning parameters shown are those available via TL1. In a practical sense fewer parameters are needed to provision the service.
5.
Packets are considered altered if the user packet that leaves the network at an egress Customer Port is not identical to the packet that entered the network at an ingress Customer Port. Packets are generally altered in
802.1TAG mode due to the addition of a VLAN tag or the alteration of the user_priority.

Metering (CIR and PIR)
Rate-shaped services offer a statistical multiplexing model that makes efficient use of shared bandwidth. Alcatel-Lucent 1665 DMX supports two of the primary forms of rate control. The two primary forms of rate control are rate limiting, and guaranteed rate services (plus various combinations of both).

Rate limiting is achieved using Peak Information Rate (PIR) provisioning. Guaranteed rate service is achieved using Committed Information Rate (CIR) provisioning. PIR institutes a limit, or "ceiling", of maximum bandwidth to be allocated to a particular customer at any time. CIR, on the other hand, provides a guaranteed minimum, or "floor" throughput even during periods of high congestion.
PIR
Burstable Bandwidth
CIR
Guaranteed Bandwidth nc-dmx2-032
When SLAs are written using CIR, Excess Burst Size (PBS), and Committed Burst Size
(CBS), they guarantee a CIR and CBS at a particular data rate. Traffic can be allowed to burst up to an excess burst size (PBS) beyond the CBS. This traffic will only be transmitted on a Best Effort basis. Any traffic above the PBS is discarded. In this type of
SLA, PIR is equal to CIR. The CIR must always be less than the maximum bandwidth that the port can support. If either CIR or PBS is set to zero, service is effectively terminated.
The second method used to specify SLAs employs CBS, PIR, CIR, and PBS. Burst Time can also be used in place of PBS. With SLAs of this sort, PIR, CIR, PBS, and CBS must be provisioned.

The Ingress Port functions are as follows:
• Traffic Classification: Determines class of service (CoS), the criteria can be 802.1p
user priority, DSCP, VLANid, or default value. Each class is mapped to an output queue. Internal management is classified into its own class.
• Flow Classification: A flow is a grouping of traffic based on certain criteria. The flow classification determines which Traffic Conditioner is used and multiple flows can be aggregated at a single traffic conditioner. Criteria is based on packet header, input port, flow, physical port, VLANid, DSCP, and/or 802.1p user priority.
• Traffic Conditioner: Traffic Conditioners perform the metering, policing, marking, and counting of ingress packets. The parameters are PIR, CIR, PBS, and CBS.
Metering measures the data rate which determines wether the packets conform to the settings for the user/port. Packets are marked according to conformance level (this is an internal marking). Policing discards packets that exceed the PIR, PBS, or PBS (see
Metering above). The conformance level determines the drop precedence (DP) for non-conforming packets.
Note: Flow Classification and Traffic Conditioning only apply to boundary ports.
Once CoS and DP are determined at the boundary port, they are used consistently throughout the network. At internal ports, CoS and DP are then used to determine egress functions (i.e. dropping and queuing). For information on boundary and internal port demarcation, see the section below entitled Boundary versus Interior
Ports.
The Egress Port functions are as follows:
• Dropping: Also known as Egress Queueing, Dropping is based on conformance level and the fullness of the queue. The drop function takes into account the total allocation queue for a particular port only. There are two drop methods employed by
Alcatel-Lucent 1665 DMX: Tail Drop and Weighted Random Early Detection
(WRED). The tail drop method discards all packets exceeding the maximum queue size. It uses only one parameter: Maximum Queue Size. WRED dropping starts at the minimum threshold and increases up to the maximum. Two drop parameters govern
WRED: Minimum Threshold and Maximum Threshold. The CoS parameter,
Maximum Drop Probability, is also provisionable in the WRED method. packets labeled with a higher drop precedence (DP) are discarded prior to those with a lower drop precedence.
• Scheduling: Scheduling allocates service for each queue. There are queues for each port: Expedited Forwarding (EF), Assured Forwarding (AF). A combination of two algorithms controls scheduling. Packets in the Strict Priority queue are transmitted first. Strict Priority is used for EF queue. Weighted Round Robin (WRR) ensures that the remaining bandwidth is allocated to each queue based on a provisioned weighting factor. WRR is used for the AF queues.

Egress functions support four classes of service (CoS). EF guaranteed low latency.
There are three levels of AF offering various degrees of guaranteed delivery including best-effort. Packets are handled differently depending on wether they originated from
Boundary or Interior ports.
• Three Colors: RED: for packets that exceed peak rate limits.
Yellow: for packets that exceed committed rate limits.
Green: for packets within committed rate limits.
Ethernet service management
Overview
The Ethernet services are managed by provisioning the following:
• Tagging (VLAN) mode
• Cross-connections
• LAN ports
• VCG (WAN) ports
• Virtual switches
• Quality of service (QoS) features.
• Performance monitoring.
For detailed information about provisionable parameters and their values, see
“Performance monitoring” (p. 5-64) .
Tagging (VLAN) modes
Alcatel-Lucent 1665 DMX supports the Private Line, transparent, and 802.1Q tagging modes. Tagging modes are provisioned on a circuit pack basis. Changing tagging modes will impact service. For detailed information about the tagging modes, see
and the WaveStar
®
CIT online help.
Cross-connections
The following types of cross-connections are used with Ethernet circuit packs.
• 1way
• 1wayPR
• 1way unswitched
For detailed information about supported cross-connections refer

Cross-connections with SONET layer protection
All SONET protected services are implemented using 1way or 1wayPR cross-connections. They are used to form a pair of bidirectional links between a VCG port and one side of a SONET tributary. 1way or 1wayPR cross-connection use one VCG on all Ethernet circuit packs (LNW63, LNW64, LNW73, LNW73C, LNW74, LNW87,
LNW170). 1way or 1wayPR cross-connections are described in
(p. A-27) . The use of VCG ports is summarized in
Cross-connections without SONET layer protection
Services that are not protected by the SONET layer are provisioned using either 1way or
1way unswitched cross-connections.
1way cross-connections can be used to provide unprotected services on BLSRs, only if the tributary (time slot) is provisioned to carry non-preemptible unprotected traffic
(NUT). The BLSR tributary(s) must be provisioned for NUT before the cross-connection is established or protected services are provided. A packet ring bandwidth could be split between working and protection (extra traffic) freeing up protected working bandwidth for other TDM services. 1way cross-connections can be used to provide unprotected services over BLSR w/ NUT, but they are less efficient than 1way unswitched cross-connections.
1way unswitched cross-connections can be used to provision unprotected traffic on
UPSRs. One cross-connection can be made between a VCG port and one side of the
SONET ring, and the other can be made between the paired VCG and the other side of the
SONET ring.
Unprotected cross-connections (1way unswitched) to UPSRs and BLSRs w/ NUT are all provisioned independently per VCG.
This pairing of VCG ports and USPR unprotected cross-connections is described in
“Unprotected tributaries” (p. A-27) . The use of VCG ports is summarized in
Cross-connection types and supported configurations
The number of Private Line Services and Packet Rings an Ethernet circuit pack can support is dependent on the type of cross-connection used and whether SONET layer protection is used.
The following table shows the cross-connection types and supported services.

LAN ports
All LAN ports have characteristics that must be the same on both sides of a link. Some characteristics are strictly physical in nature. They can only be changed by using different equipment. Some examples of these characteristics are cable type (for example, twisted pair, fiber) and optical type (short reach, long reach). For more information about the
Ethernet circuit packs, see
“Ethernet/SAN circuit packs” (p. A-7) .

2.
Only VCG1 is available when protected cross-connection is used.
3.
VCG2 is not available when protected cross-connection is used on VCG1. VCG4 is not available when protected cross-connection is used on VCG3
4.
Although the LNW74 can be used in slot G1, only the optical ports are functional. When mixing an LNW74 with an optical only pack, all 24 ports (16 electrical and 8 SFP) ports on the LNW74 are available. When pairing the LNW74 with another LNW74, ONLY the 8 SFP ports on each pack are usable, for a total of 16
SFP ports per function group
5.
When a VLF Main pack (LNW59, LNW82, or LNW504) is used, Alcatel-Lucent 1665 DMX allows
Ethernet packs to be installed in Slot 1 and/or 2 of a function unit or growth slot. Certain circuit pack/slot equipage restrictions apply. For more information see
“Very large fabric (VLF) engineering rules” (p. 6-15) .

When VLF Mains are not used, Ethernet packs, except for the LNW170 in protected mode, can only be installed in Slot 1 of a function unit or growth slot. When it is in protected mode, the LNW170 can occupy both slots with VLF or non-VLF Mains installed.
Virtual switch
A virtual switch is a logical grouping of LAN ports and VCG ports that share interconnect and share a common set of properties. A virtual switch may support one or more spanning trees; a spanning tree can only belong to one virtual switch.
A port (LAN or VCG) can only be assigned to one virtual switch at a time.
The LNW170 circuit packs can support a maximum of 16 virtual switches on each circuit pack. The LNW910 supports one virtual switch.
The following WaveStar

Private LAN, Virtual Private LAN, and Virtual Private Line services
In Private LAN service, LAN ports and SONET capacity are dedicated to one subscriber.
In Virtual Private LAN service, several subscribers share SONET capacity and can share
LAN ports. Traffic is segregated by its VLAN/port TAG. Virtual Private Line service is subset of Virtual Private LAN service, where the subscriber is given a point-to-point service with dedicated LAN ports.

SONET-based distance extensions for ESCON/FICON/Fibrechannel services
Overview
This section details the functionality of SONET-based SAN distance extension supported by the LNW73. For other information on the functionality of the LNW73, see
“Ethernet/SAN circuit packs” (p. A-7) and
“Differential delay buffers” (p. A-25) .
ESCON design guidelines
ESCON services enter Alcatel-Lucent 1665 DMX or Alcatel-Lucent 1665 DMXtend through ESCON PTM attached to LNW73 plug-in circuit and are routed out OC48/192
SONET interfaces from SONET plug-ins in slot main-1 (and main-2, if protection is desired). The SONET signal can be routed through any number of intermediate SONET systems (including none) and terminates into another Alcatel-Lucent 1665 DMX or
Alcatel-Lucent 1665 DMXtend to provide a network transport of ESCON services.
When a shelf is equipped with non-VLF Mains, an LNW73 may be placed in slots fn-a-1,fn-b-1,fn-c-1, fn-d-1 or growth-1 (5 slots). When the shelf is equipped with VLF
Mains, LNW73 can occupy both slots 1 and 2 of a Function/Growth unit. Up to 4
ESCON services may be provided in a single LNW73 plug-in, each service requiring 4
STS-1 bandwidth reserved in the SONET domain. A Alcatel-Lucent 1665 DMX/OC48 system can provide 12 ESCON services (limited by SONET bandwidth).
A Alcatel-Lucent 1665 DMX/OC192 system with non-VLF Mains can provide 20
ESCON services (limited by the number of slots that may be equipped with LNW73).
When equipped with VLF Mains, it can provide up to 40 ESCON services.
Reliability/Line and pack protection options
To protect against SONET network failures and main pack failures, Alcatel-Lucent 1665
DMX can be equipped with redundant circuit packs in both main slots and can be provisioned for UPSR or BLSR protection. To protect against SONET network failures and main pack failures, Alcatel-Lucent 1665 DMX can be equipped with redundant circuit packs in both main slots and be provisioned for UPSR protection. Using SONET protection significantly increases the reliability of individual end-to-end ESCON services.
Circuit pack equipage and provisioning
Each LNW73/73C used must be set to select the pack type of ESCON (see ED-EQPT).
Each port to be used must be equipped with an Alcatel-Lucent specified ESCON
Pluggable Transmission Module (PTM). A PTM is similar in functionality to a GBIC pluggable unit. If a Virtual Concatenated (VCAT) signal format is desired, the
ED-DPORT-DATA command is used to select it.

SONET-based distance extensions for ESCON/FICON/Fibrechannel services
....................................................................................................................................................................................................................................
Circuit bandwidth choices
A full rate ESCON service may be provisioned as a SONET STS-1-4v (VCAT),
STS-3c-2v(VCAT) or a STS-12c Contiguously Concatenated (CCAT). The most bandwidth efficient is STS-1-4v.
Interface specifications to ESCON interfaces
Alcatel-Lucent 1665 DMX/Alcatel-Lucent 1665 DMXtend use standards compatible
PTM modules. See
Chapter 10, “Technical specifications”
for optical specification, loss budget, connector and fiber type requirements.
Distance limitations/transmission delay engineering
Distance between the ESCON equipment and the Alcatel-Lucent 1665
DMX/Alcatel-Lucent 1665 DMXtend are typically limited by the interface link specification of the ESCON interface.
The total distance allowed including the SONET extension is typical a function of the delay requirements of the ESCON application.
Synchronous ESCON applications typically suffer performance droop if the application is subjected to more than 100 microseconds of one way transmission delay (the equivalent of delay through 20 km of fiber). For planning purposes, each Alcatel-Lucent 1665 DMX adds the equivalent 25 microseconds or 5 km of fiber. Therefore, synchronous ESCON applications would suffer droop if the total actual fiber distance (adding the ESCON to
Alcatel-Lucent 1665 DMX and Alcatel-Lucent 1665 DMX to Alcatel-Lucent 1665 DMX links) is more than 10 km.
Asynchronous ESCON applications are much more tolerant to transmission delay, typically able to function at delays of 1000 microseconds (200 km) or longer. Each
Alcatel-Lucent 1665 DMX/Alcatel-Lucent 1665 DMXtend or other SONET system in the path of such a network would add the equivalent of 5 km of fiber.
Full-rate FICON/FC design guidelines
FICON/FC services enter Alcatel-Lucent 1665 DMX or Alcatel-Lucent 1665 DMXtend through FICON/FC PTM attached to LNW73 plug-in circuit is routed out OC48/192
SONET interfaces from SONET plug-in in slot main-1 (and main-2, if protection is desired).
The SONET signal can be routed through any number of intermediate SONET systems
(including zero) and terminates into another Alcatel-Lucent 1665 DMX or Alcatel-Lucent
1665 DMXtend to provide a network transport of a FC/FICON service.
An LNW73 may be placed in slots fn-a-1,fn-b-1,fn-c-1, fn-d-1 or growth-1 (5 slots) of a
Alcatel-Lucent 1665 DMX. When the shelf is equipped with VLF Mains, LNW73 can occupy both slots 1 and 2 of a Function/Growth unit.

....................................................................................................................................................................................................................................
Up to 2 full rate 1G FICON/FC services (or one 2G FICON/FC service) may be provided in a single LNW73 circuit pack, each service requiring 19 STS-1 or 6 STS-3c bandwidth units reserved in the SONET domain (37 STS-1 or 12 STS-3c for 2G FICON/FC).
When operating in asynchronous Fibre Channel (FC) mode, 2 ports are available at
2Gbps FC, or 4 ports at 1Gbps FC, or 1 port at 2Gbps FC and 2 ports of 1Gbps FC. When operating in synchronous FC mode, 1 port is available at 2Gbps FC, or 2 at 1Gbps FC.
A Alcatel-Lucent 1665 DMX/OC48 system can provide 2 full rate FICON/FC 1G services (limited by SONET bandwidth).
A Alcatel-Lucent 1665 DMX/OC192 system can provide 10 FICON/FC 1G services
(limited by the number of slots that may be equipped with LNW73).
Buffer-to-buffer credits are handled exclusively by FICON/FC switches/devices.
Reliability/Line and pack protection options
To protect against SONET network failures and main pack failures, Alcatel-Lucent 1665
DMX can be equipped redundant circuit packs in both main slots and be provisioned for
UPSR or BLSR protection.
Using SONET Protection dramatically increases the reliability of end to end FICON/FC services.
Circuit pack equipage and provisioning
Each LNW73 used must be set to select the pack type of FICON/FC (see ED-EQPT).
Each port to be used must be equipped with an Alcatel-Lucent specified FC/FICON
Pluggable PTM. A PTM is similar in functionality to a GBIC pluggable unit. If a VCAT signal format is desired, the ED-DPORT-DATA command is used to select it.
Circuit bandwidth choices
A full rate 1G FICON/FC service may be provisioned as a SONET STS-1-19v (VCAT),
STS-3c-6v(VCAT). The most bandwidth efficient is STS-3c-6v. A full rate 2G FICON/FC service may be provisioned as a SONET STS-1-37v (VCAT), STS-3c-12v (VCAT). The most bandwidth efficient is STS-3c-12v.
Interface specifications to FICON/FC interfaces
Alcatel-Lucent 1665 DMX uses standards compatible PTMs. The same PTM works for both FICON and FC and both 1G and 2G. See
Chapter 10, “Technical specifications”
for optical specification, loss budget, connector and fiber type requirements.
Distance limitations/transmission delay engineering
Distance between the FICON/FC equipment and the Alcatel-Lucent 1665 DMX are typically limited by the interface link specification of the FICON/FC interface.
The total distance allowed including the SONET extension is typically a function of the delay requirements of the FICON/FC application.

....................................................................................................................................................................................................................................
Synchronous FICON/FC applications performance typically suffers if the application is subjected to more than 600 microseconds of one way transmission delay (the equivalent of delay through 120 km of fiber). Refer to your particular client equipment engineering rules for distance limitations. For planning purposes, each Alcatel-Lucent 1665 DMX adds the equivalent 25 microseconds or 5 km of fiber.
Asynchronous FICON/FC applications are much more tolerant to transmission delay, typically able to function at delays of 1000 microseconds (200 km) or longer. Many FC switches offer extended buffer credits for asynchronous applications that allow up to 3600 microseconds of delay without performance droop. Each Alcatel-Lucent 1665 DMX or other SONET system in the path of such a network would add the equivalent of 5 km of fiber.
FC/FICON services-extended distances - BB credits managed in Alcatel-Lucent 1665
DMX/Alcatel-Lucent 1665 DMXtend
To extend asynchronous FICON/FC applications beyond the buffer to buffer credit limits of the attached FC Switches, Alcatel-Lucent 1665 DMX and Alcatel-Lucent 1665
DMXtend can be provisioned to manage the BB Credits and eliminate performance droop related to insufficient BB credit across the network. This implementation is based on the
ITU G.7041 and T11 FC-BB-3_GFPT standards work and provides sufficient credits for full performance at 2500 km for 2G services.
To use this mode, the gfptype (in the ED-DPORT-DATA command) must be provisioned to ASYNC-FC (even if it is a FICON service). Buffer credits are automatically adjusted within Alcatel-Lucent 1665 DMX and no additional provisioning required. Attached
FICON/FC devices should be provisioned to use for R_RDY flow control (as opposed to proprietary Inter-Switch Link (ISL) flow control schemes.
Illustrative examples of some FC switch configurations are provided below.
EMC certification
Alcatel-Lucent 1665 DMX has been qualified by EMC eLab Testing and with Brocade
Fabric Aware Testing. Alcatel-Lucent 1665 DMX has been tested with various FC/FICON switches used with storage equipment. This testing has yielded some simple guidelines
(listed below) that need to be followed to ensure smooth interworking between
Alcatel-Lucent 1665 DMX and some of the FC/FICON switches listed above.
General FC/FICON equipment port configuration for connection to Alcatel-Lucent 1665 DMX
Please use the following guidelines to ensure interoperability between FC/FICON equipment and Alcatel-Lucent 1665 DMX.

To assure minimal link start up and recovery times, the following configurations are recommended for all ports attached to Alcatel-Lucent 1665 DMX:
• Configure port speed to match application: I.e. use 1G or 2G mode instead of auto-negotiate mode.
• Configure ports to not waste time trying to determine if Alcatel-Lucent 1665 DMX is arbitrated loop port type
To use buffer credits in Alcatel-Lucent 1665 DMX when gfptype is set to async-FC, configure ports to use R_RDY mode buffer credit management instead of proprietary link buffer credit management.
If compression is desired on Alcatel-Lucent 1665 DMX and gfptype is set to async-FC, set the number of link buffer credits to 8 or less, otherwise the operational state of compression will stay disabled.
Brocade interworking examples
Please use the following guidelines to ensure interoperability between the specified
Brocade equipment and Alcatel-Lucent 1665 DMX.
Brocade Silkworm 3800
Perform the following tasks on all ports connected to the Alcatel-Lucent 1665 DMX:
• Through the CLI, use the portcfgSPEED {port num}, {1 or 2, not 0}
• Then use the portcfgGPORT {portnum}, {1, not 0}
In addition, to use buffer credits on Alcatel-Lucent 1665 DMX when gfptype is set to async-FC, use portcfgISLMODE {portnum}, {1, not 0}.
To use compression on Alcatel-Lucent 1665 DMX when gfptype is set to async-FC, use switchdisable, then use the configure command to set fabric.ops.BBCredit to 8 or less.
Brocade Silkworm 2250
Perform the following tasks on all ports connected to the Alcatel-Lucent 1665 DMX:
• Through the CLI, use the portcfgSPEED {port num}, {1 or 2, not 0}
• Then use the portcfgGPORT {portnum}, {1, not 0}
In addition, to use buffer credits on Alcatel-Lucent 1665 DMX when gfptype is set to async-FC, use switchdisable, then use the configure command to set fabric.ops.longdistance=1
To use compression on Alcatel-Lucent 1665 DMX when gfptype is set to async-FC, use switchdisable, then use the configure command to set fabric.ops.BBCredit to 8 or less.
Cisco MDS 9120 or MDS 9216 interworking examples
Please use the following guidelines to ensure interoperability between the Cisco MDS
9120 or MDS 9216 equipment and Alcatel-Lucent 1665 DMX.

Perform the following tasks on all ports connected to the Alcatel-Lucent 1665 DMX:
• Through the GUI, click on FC port, set admin Speed to 1Gb or 2Gb not auto
• Through the GUI, click on FC port, set admin Mode to E or TE, not auto
In addition, to use buffer credits on Alcatel-Lucent 1665 DMX when gfptype is set to async-FC, it is important to note that Cisco uses ISL mode as R_RDY mode by default.
To use compression on Alcatel-Lucent 1665 DMX when gfptype is set to async-FC, through the GUI, click on FC port, then click on BBCredit and then set admin BBCredit to 8 or less.
MC Data Sphereon 4500 interworking examples
Please use the following guidelines to ensure interoperability between the MC Data
Sphereon 4500 equipment and Alcatel-Lucent 1665 DMX.
Perform the following tasks on all ports connected to the Alcatel-Lucent 1665 DMX:
• Through the GUI, click on Configure, then click on ports, on the appropriate ports, set
Speed to 1Gb/sec or 2Gb/sec
• Through the GUI, click on Configure, then click on ports, on the appropriate ports, set
Type to E port
In addition, to use buffer credits on Alcatel-Lucent 1665 DMX when gfptype is set to async-FC, it is important to note that Sphereon uses ISL mode as R_RDY mode by default.
To use compression on Alcatel-Lucent 1665 DMX when gfptype is set to async-FC, set any port numbered "4" or higher to use 5 credits (ports 0–3 use 12 credits).

DA’d circuit pack descriptions
Purpose
This section briefly describes Alcatel-Lucent 1665 DMX circuit packs that are DA'd and no longer orderable. These packs could be present in your existing network.
System Controller (LNW1)
The SYSCTL provides communication with other circuit packs on the Alcatel-Lucent
1665 DMX shelf. The SYSCTL supports all Alcatel-Lucent 1665 DMX operations interfaces, including IAO LAN (OSI or TCP/IP), TL1/X.25, PC-CIT, office alarms, and miscellaneous discretes. The SYSCTL also supports DCC terminations for each optical line interface.

The SYSCTL faceplate has push-button switches, alarm/status LEDs, and a 7-segment numeric display to facilitate local operations. The SYSCTL provides redundancy by duplicating all cross-connect information on the OLIU circuit packs. Transmission is not affected if the SYSCTL fails.
The SYSCTL circuit pack provides a microprocessor, nonvolatile memory to store the generic program software and provisioning database, and additional memory for system operation. The SYSCTL circuit pack also has interfaces across the backplane to monitor and control every circuit pack in the shelf.
The SYSCTL supports PC-CIT front access to the Alcatel-Lucent 1665 DMX via the IAO
LAN and a serial RS-232 port located on the back of the Alcatel-Lucent 1665 DMX shelf.
28DS1 (LNW6)
The LNW6 is not supported when Alcatel-Lucent 1665 DMX is equipped with VLF Main packs. LNW6 contains 28 DS1 ports that can be cross-connected to VT1.5 timeslots when the system is operating with a UPSR, 1+1, or BLSR Main interface. Hairpin cross-connections to OCn and other electrical interfaces are also supported. This circuit pack is 1x1 protected, and non-revertive protection switching is supported. Line build-outs and DS1 signal encoding are software provisionable. This circuit pack terminates up to 28 bidirectional DS1 electrical signals and supports the transport of DS1 signals coded in either alternate mark inversion (AMI) or bipolar 8-zero substitution
(B8ZS) modes. The signals received from the DSX-1 are mapped into SONET VT1.5
signals and then routed to the high-speed OLIU circuit pack.
The LNW6 circuit pack can occupy Function Unit groups A, B, C, and D. All electric interface circuit packs are 1x1 hardware protected. So, although both slots in each function group can house a LNW6 circuit pack, one slot in each function group populated by LNW6 circuit pack is always used for hardware protection. Thus the Alcatel-Lucent
1665 DMX shelf supports up to 112 working ports when four Function Unit groups are equipped with the LNW6 circuit pack.
In addition to maintenance and provisioning functions, the 28DS1PM circuit pack provides performance monitoring capabilities.
Whenever upgrading LNW6 to LNW7 circuit packs, it is necessary to first install an
LNW8 circuit pack to ensure that the upgrade is completed without loss of service.
48DS3/EC1 (LNW19)
The 48DS3/EC1 (LNW19) circuit pack can be used only in the high capacity shelf, contains 48 ports, is 1x1 protected, and supports nonrevertive protection switching. The
48DS3/EC1 circuit pack provides bidirectional transport of 48 DS3/EC-1 signals and maps the DS3/EC-1 signals into corresponding STS-1 signals, and supports transport of
DS3 signals coded in bipolar 3-zero substitution (B3ZS). DS3 or EC-1 service is provisionable on a per-port basis within each pack.

The LNW57 circuit pack may occupy Main slots 1 and 2. Fiber access is provided via a pair of LC-type connectors on the LNW57 faceplate.
The LNW57 circuit pack utilizes a "dither tone" to frequency modulate the laser. This technique is used to minimize the effects of Stimulated Brillouin Scattering (SBS). At high optical launch powers, SBS can cause an acoustic back-scattering phenomenon in fibers. The dither tone effectively broadens the spectrum of the narrow optical pulse, thus raising the threshold power where SBS becomes an issue.
Normally, Alcatel-Lucent recommends that optical output of the OC-192 circuit packs be amplified to no more than +10 dBm. However, with the dither tone circuit incorporated into the LNW57 circuit pack, optical amplification of this circuit pack to much higher power levels is acceptable.
For fibers carrying multiple wavelengths in DWDM systems, it should be noted that the individual channel (individual wavelength) power determine the SBS threshold, not the total composite power of all the channels.
OC-192 OLIU (LNW60)
The LNW60 circuit pack is based on the LNW57 circuit pack. It has the same characteristics, capabilities, and specifications as the LNW57 circuit pack, but it also includes an on-board, integrated optical amplifier. When the on-board amplifier is in use, the LNW60 circuit pack is capable of bridging spans of up to 127 km. The LNW60 circuit pack presents the possibility of savings in CAPEX, OPEX (no separate management for external optical amplifier required), and space.

The LNW66 circuit pack has 24 10/100T Fast Ethernet ports and provides data transport at the rate of 10/100 Mbps using standard Ethernet switching IEEE 802.1, standard encapsulation, and standard STS-1 virtual concatenation according to ITU G.707. The
LNW66 can transmit signals across spans as long as 100 meters. Each LNW66 circuit pack can support 1 packet ring. The LNW66 is an unprotected pack.
Alcatel-Lucent 1665 DMX does not allow installation of two packs with electrical interfaces in adjacent slots within the same Function Unit or Growth Group (other than an equipment-protected pair). Therefore, in systems equipped with VLF mains, LNW66 packs can reside in either Slot 1 or Slot 2 of a group, but not both at the same time.
Telcordia
®
only supports electrical packs in Slot 1 of a group. However, another optical
(Ethernet or SONET) pack may be installed in the other slot. In non-VLF equipped shelves, LNW66 can only occupy Slot 1 of a particular group. When the LNW66 circuit pack occupies slot 1 of a Function Unit group, slot 2 must be populated with an apparatus blank.
1000BASE-SX (LNW67) optical Ethernet interface
This 2-port Ethernet interface provides short-reach high-speed optical data transport at the rate of 1 Gb/s using standard Ethernet switching IEEE 802.1, standard encapsulation, and standard STS-1 virtual concatenation according to ITU G.707.
The LNW67 is an unprotected pack. Fiber access is provided by two LC-type connector pairs on the LNW67 faceplate. The LNW67 transmits signals at a wavelength of 850 nm.
The LNW67 requires the use of multimode fiber cable. Each LNW67 circuit pack can support 2 packet rings or 2 GbE private lines (protected or unprotected).
When Alcatel-Lucent 1665 DMX is not equipped with VLF Main packs, LNW67 packs can only be placed in Slot 1 of any function group or growth slot in the shelf (A1-G1).
Alcatel-Lucent 1665 DMX support a total add/drop capacity of 10 optical GbE ports if all slots are equipped with LNW67 circuit packs.
When Alcatel-Lucent 1665 DMX is equipped with VLF Main packs, Ethernet packs can occupy both Slot 1 and 2 of a Function or Growth Unit (where applicable). With VLF
Mains and all tributary slots populated with LNW67 packs, Alcatel-Lucent 1665 DMX provides a total add/drop capacity of 20 optical GbE ports.
When VLF Mains are not used, if the LNW67 circuit packs occupy slot 1 of a Function
Unit group, slot 2 must be populated with an apparatus blank.

UPSR/BLSR or through the IEEE 802.1w (or 802.1d) spanning tree algorithm.
The LNW70 pack can also use electrical PTMs that are provisionable to support either
100BASE-T or 1000BASE-T traffic. The electrical FE (100BASE-T) PTMs can occupy ports 1–8. The GbE (1000BASE-T/X) PTMs are restricted to ports 1–4.
The LNW70 pack uses standard Ethernet switching (IEEE 802.1), standard encapsulation, and standard STS-1 virtual concatenation according to ITU G.707. Fiber access is provided by LC-type connector pairs on the LNW70 faceplate.

The LNW70 pack feature Pluggable Transmission Module (PTM) electrical and optical interfaces. PTMs are “pluggable” in the sense that they can be plugged into a circuit pack as they become necessary. This allows customers to grow their network incrementally, only realizing the full cost for optics as the need to provision service on (and thus receive revenue from) them becomes necessary. LNW70 pack is purchased and shipped with no ports populated with functioning optics. The ports remain empty until the customer decides to place interfaces in them. The electrical FE (100BASE-T) PTMs can occupy ports 1–8. The GbE (1000BASE-T/X) PTMs are restricted to ports 1–4.

The LNW527 circuit pack employs tunable lasers that support 4 separate frequencies. The
LNW527 lasers can be made to transmit different frequencies. This feature offers obvious advantages to single frequency circuit packs in that one pack may be ordered and used to support a variety of frequency requirements. Packs can be reused in applications requiring different frequencies and thus the need to order packs simply to support different frequencies can, in some cases, be avoided.

This feature offers obvious advantages to single frequency circuit packs in that one pack may be ordered and used to support a variety of frequency requirements. Packs can be reused in new applications requiring different frequencies and thus the need to order new packs simply to support different frequencies can, in some cases, be avoided.
OC-192 OLIU (LNW555)
The OC-192 OLIU (LNW555) circuit pack is a long reach (80 km) 1533.47 nm optical line interface unit. The LNW555 supports OC-192 add/drop, UPSR, and BLSR configurations, single- and dual-homing, non-revertive linear and bidirectional 1+1 protection switching, and VT1.5, STS-1, STS-3(c), STS-12(c), and STS-48(c) signal transport. The LNW555 circuit pack can cross-connect VTs in any 48 of 192 STS-1s in the OC-192 signal. The Stratum 3 timing generator and central TDM switch fabrics are embedded in the OC-192 OLIU.
The LNW555 may occupy Main slots 1 and 2. Fiber access is provided via a pair of
LC-type connectors on the LNW555 faceplate.
Standard Shelf
The Standard Shelf was DA'd June 2004 and was replaced with the High Capacity Shelf that incorporated additional DS1/DS3 D-SUB cable connectors on the rear of the shelf to support 224 DS1s or 192 DS3s. In order to support this amount of traffic, the High
Capacity Shelf must be equipped with new, higher density DS1 and DS3 circuit packs that became available in Release 3.1.
The following circuit packs
cannot
be installed in the Standard Shelf. They are only supported in the High Capacity Shelf.
• VLF mains: LNW82, LNW59, LNW504
• Packs that require VLF mains: LNW55, LNW62, LNW64, LNW603, LNW910
• High-density packs that require the High Capacity Shelf: LNW8, LNW801, LNW19,
LNW19B, LNW20
The dimensions of the Standard Shelf (848632956) are
• Width: 17.6 inches
• Height: 16 inches

20-amp shelf
The 20 Amp version of the High-Capacity shelf was DA's 10/2012. The 30 Amp
High-Capacity shelf is the replacement. The 20 Amp version contains the same functionality as the 30 Amp High-Capacity shelf, but it is limited to a total current drain of 20.0 amps. In applications where the planned equipage will never exceed 20.0 amps, power cables can be sized accordingly, thus enabling a considerable savings in power cable investment.
Important! With VLF Main packs, overload and overheating in the 20-amp shelf is possible given certain combinations of circuit packs in the low-speed slots.
VLF Main packs are not necessarily precluded from use in the 20 Amp shelf, but there are four configurations that could cause power issues if you lose one power feed or circuit breaker, the shelf’s current drain will exceed the 20.0A capacity of the remaining circuit breaker and your shelf will lose power:
• Configuration 1: 1xLNW2, 2xLNW59s, 10xLNW170s, and 1xFan unit;
• Configuration 2: 1xLNW2, 2xLNW59s, 10xLNW20s, and 1xFan unit;
• Configuration 3: 1xLNW2, 2xLNW59s, 8xLNW20s 2x(any OC-n low-speed circuit pack), and 1xFan unit;
• Configuration 4: 1xLNW2, 2xLNW82s, 10xLNW170s, and 1xFan unit.

1+1 (bidirectional)
The bidirectional 1+1 protection switching architecture protects against failures of the optical transmit/receive equipment and their connecting fiber facility. One bidirectional interface (two fibers plus associated OLIUs on each end) is designated "service," and the other is designated
"protection." In each direction, identical signals are transmitted on the service and protection lines
("dual-fed"). The receiving equipment monitors the incoming service and protection lines independently and selects traffic from one line (the "active" line) based on performance criteria and technician/OS control. In bidirectional 1+1 switching, the network elements are not independent. When a protection switch is requested at a network element, both network elements perform protection switching.
1+1 (unidirectional)
The unidirectional 1+1 protection switching architecture protects against failures of the optical transmit/receive equipment and their connecting fiber facility. One bidirectional interface (two fibers plus associated OLIUs on each end) is designated "service," and the other is designated
"protection." In each direction, identical signals are transmitted on the service and protection lines
("dual-fed"). The receiving equipment monitors the incoming service and protection lines independently and selects traffic from one line (the "active" line) based on performance criteria and technician/OS control. In unidirectional 1+1 switching, both service and protection lines could be active at the same time (service in one direction, protection in the other).

1xN protection switching pertains to circuit pack protection that provides a redundant signal path through Alcatel-Lucent 1665 DMX (it does not cover protection switching of an optical facility; see "1+1"). In 1xN switching, a group of N service circuit packs share a single spare protection circuit pack. 1x1 is a special case of 1xN, with N=1. In 1x1, only one is active at a time.
802.1Q Mode
In 802.1Q Mode, a circuit pack can be provisioned to use an incoming frame's VLAN tag either to add a VLAN tag associated with the port for untagged frames or to drop an incoming frame if its
VLAN tagging does not meet provisioned specifications. The priority bits in an incoming frame's
VLAN tag can also be used to affect the handling of the frame.

No Request State
This is the routine-operation quiet state in which no external command activities are occurring.
Node
A network element in a ring or, more generally, in any type of network. In a network element supporting interfaces to more than one ring, node refers to an interface that is in a particular ring.
Node is also defined as all equipment that is controlled by one system controller. A node is not always directly manageable by a management system.
Nonpreemptible unprotected traffic (NUT)
Traffic carried on (working and/or protection) BLSR channels for which protection switching has been provisioned as disabled. NUT must be employed when using an alternate protection scheme for data such as RSTP. As the name implies, NUT is unprotected and not preempted in the event of a protection switch. NUT carried on nonpreemptible unprotected channels affords a higher level of survivability as compared to extra traffic, which is preempted during a protection switch, but a lower level of survivability as compared to working traffic, which is carried on its corresponding protection channel during a protection switch.
Nonrevertive Switching
In nonrevertive switching, an active and standby line exist on the network. When a protection switch occurs, the standby line is selected to support traffic, thereby becoming the active line. The original active line then becomes the standby line. This status remains in effect even when the fault clears. That is, there is no automatic switch back to the original status.

Port (also called Line)
The physical interface, consisting of both an input and output, where an electrical or optical transmission interface is connected to the system and may be used to carry traffic between network elements. The words "port" and "line" may often be used synonymously. "Port" emphasizes the physical interface, and "line" emphasizes the interconnection. Either may be used to identify the signal being carried.
Port Protection Group
A user provisioned association of protected optical interface ports. This association is used for line protection. The group of ports represent both a protection switching entity and also a set of lines that carry services to/from another network element. The port protection groups also determine the set of logical tributaries from and to which cross-connections can be provisioned.
Port State Provisioning
A feature that allows a user to suppress alarm reporting and performance monitoring during provisioning by supporting multiple states (automatic, in-service, and not monitored) for low-speed ports.

See Nonrevertive.
RFI
Remote Failure Indication
Ring
A configuration of nodes comprised of network elements connected in a circular fashion. Under normal conditions, each node is interconnected with its neighbor and includes capacity for transmission in either direction between adjacent nodes. Path switched rings use a head-end bridge and tail-end switch. Line switched rings actively reroute traffic over a protection line.
Ring (0x1) Low-Speed Interface
Formerly referred to as dual 0x1 or single 0x1. In ring applications, Alcatel-Lucent 1665 DMX may use a 0x1 interface, meaning both fibers carry service, as opposed to a linear (1+1) low-speed interface where one fiber is used for service and other for protection. See 1+1.

Virtual LAN (VLAN)
A virtual LAN (VLAN) is a subset of a LAN. A VLAN is created by putting VLAN IDs in packets that indicate membership to a VLAN of that ID. A Local Area Network (LAN) can have multiple VLANs within it, up to the number of IDs available. Members (ports) of different
VLANs do not see the traffic of VLANs of which they are not members. A port may be a member of many VLANs (LAN ports in 802.1Q mode, WAN ports). In the Transparent mode, a LAN port is typically assigned membership to a single VLAN.
In Transparent mode, VLANs are assigned to ports using Port Tag (ed-eport and ed-vcg. In
802.1Q mode, VLANs are assigned to ports using VLAN IDs (ent-vlan/ed-vlan).
A VLAN tag is the specific field of information in a packet that carries the VLAN ID number.
Virtual Switch
A virtual switch is a grouping of ports on an Ethernet switch that results in partitioning of the switch into multiple "logical" switches. A port may only be a member of one virtual switch.
Virtual Tributary (VT)
A structure designed for transport and switching of sub-STS-1 payloads. There are currently four sizes: VT1.5 (1.728 Mb/s), VT2 (2.304 Mb/s), VT3 (3.456 Mb/s), and VT6 (6.912 Mb/s).
