Chapter 1. Introduction
1.1 General
Thank you for choosing the Fiber Multiplexer. If you would like to skip right to the installation and configuration of the Multiplexer, proceed to Chapters 3 and 4.
The MULTIPLEXER UNIT is a 1U (1.75") high standalone or 19" rack mountable
E1/T1/Data/LAN Bridge multiplexer over fiber link, built upon a highly modular design.
The MULTIPLEXER UNIT provides an economic optical connection solution in highdensity E1 and/or T1 installations such as between central offices. By utilizing a modular design, a large variety of configurations may be realized and the unit may be custom tailored for each specific application. The 4-CHANNEL E1, T1, V.35 (X.21/RS-530/RS-
449) data, Ethernet Bridge Port cards and optical interface card are all optional. The standard unit is a chassis with local control and provisions for single or dual power. The appropriate optical interface card may be selected to support multi- mode or single- mode fiber cable operation, with or without redundancy. Optical interface connections may be chosen from a wide variety of connectors including ST™, SC, FC, LC, or MT-RJ. WDM
(Wave Division Multiplexing) optical interfaces are also available. The range of transmission for optical connection is from 2Km (for multi- mode) up to 120Km (single mode). Optional External Clock Card (external or internal clock source) and SNMP Card
(for local and remote management purposes) may be installed in the chassis.
1.2 Functional Description
The MULTIPLEXER UNIT basic chassis is available in five power supply configurations. Depending on the model, power may be derived from single AC
100~240VAC, single DC +20~60VDC, dual AC 100~240VAC, dual DC +20~60VDC, or
AC plus DC power sources. The MULTIPLEXER UNIT provides all Line Card connections on the rear panel. There are 4 slots available for installation of 4-CHANNEL
E1 or T1 Port Cards (G.703 E1/T1), 4-CHANNEL Data Port Cards, or Single-
CHANNEL Ethernet Bridge LAN Port Cards into the MULTIPLEXER UNIT chassis.
Each 4-CHANNEL Port Card provides 4 individual channels of E1, T1, or Datacom per
Port Card. The first release of the Single-CHANNEL Ethernet Bridge LAN Port Card provides one 2048kbps WAN link for 10/100Base Ethernet bridging. A later release version will provide full 8Mbps (E1 x 4) link speed.
The 4-CHANNEL E1 Port Card has the option of using BNC (75 Ohm unbalanced) or RJ-45 (120 Ohm balanced) connectors for E1 Line interface connections and supports four separate E1 channels at a transmission rate of 2048Kbps (transparent unframed E1) each.
1-1
Multiplexer Unit : Apr 2003
Chapter 1. Introduction
The 4-CHANNEL T1 Port Card provides four RJ-45 (100 Ohm balanced) connectors for T1(DS1) Line interface connections and supports four separate T1 (DS1) channels at a transmission rate of 1544Kbps (transparent unframed T1) each.
The 4-CHANNEL Data Port Card provides four standard nx56/nx64Kbps, up to
2048Kbps for V.35 (or X.21, RS-530, RS-449, RS-232) DCE ports on MB34 (DB15,
DB25, DB37, DB25) female or male connectors (required adapter cables optional) for direct connection to terminal equipment.
The Ethernet Bridge Port Card provides an RJ-45 connector for 10Base-T or
100Base-TX Ethernet (auto negotiation) connections. The bridging function provides LAN to LAN segment links which operate under the same network address space.
When any port card is inserted in a slot, LEDs on the front panel will show both the channel statuses and any alarm indications.
The MULTIPLEXER UNIT E1 and T1 Interface Cards fully meet all E1 and T1 specifications including ITU-T G.703, G.732, G.733, G.823 and G.824. The Bridge
Interface Card meets all Ethernet specifications for IEEE802.3 and IEEE802.3u.
Each 4-CHANNEL Port Card features diagnostic capabilities for performing local loop back or remote loop back (except for Ethernet Bridge card). The loop back function is controlled by the front panel LCD menu, terminal mode (RS-232 console) or via option
SNMP.
Up to five clock source selections are provided. Without the external clock card option, the unit operates from clock recovery only. When the external clock card option is installed, additional clock sources may be selected from an additional internal oscillator (located on the option card) or from an external clock references for E1 PCM, E1 TTL, T1 PCM, or T1
TTL. All E1 and T1 connected equipment must recover or slave their timing to the
MULTIPLEXER UNIT's internal oscillator or from an external reference clock (with option).
When the MULTIPLEXER UNIT is ordered with an optional SNMP Card, the card is installed inside the chassis. Configuration is accomplished via local control on the asynchronous RS-232 port with a standard VT-100 terminal, via Ethernet and Telnet, or via any standard SNMP network management software over Etherenet. If the SNMP Card option is not installed, local and remote management are still possible via the units internal menu system accessible from the front panel LCD and menu keys, or via the asynchronous
RS-232 port with a standard VT-100 terminal.

1.4 E1 Signal Structure
E1 link line rate
The E1 line operates at a nominal rate of 2.048Mbps.
E1 link line coding
The basic E1 line signal is coded using either the Alternate Mark Inversion (AMI) or
HDB3 rule.
In the AMI format, "ones" are alternately transmitted as positive and negative pulses, whereas "zeros" are transmitted as a zero voltage level. AMI is not used in most 2.048Mbps transmissions because synchronization loss occurs during long strings of data zeros.
In the HDB3 format, a string of four consecutive zeros is replaced with a substitute string of pulses containing an intentional bipolar violation. The HDB3 code substitutions provide high pulse density so that the receiving equipment is able to maintain synchronization with the received signal.
The 4-CHANNEL E1 Port Card supports two E1 line codes:
AMI coding.
HDB3 coding.
The 4-CHANNEL E1 Port Card supports only transparent unframed format.
1.5 T1(DS1) Signal Structure
T1 link line rate
The T1 line operates at a nominal rate of 1.544Mbps.
T1 link line coding
The basic T1 line signal is coded using either the Alternate Mark Inversion (AMI) or
B8ZS rule.
In the AMI format, "ones" are alternately transmitted as positive and negative pulses, whereas "zeros" are transmitted as a zero voltage level. AMI is not used in most 1.544Mbps transmissions because synchronization loss occurs during long strings of data zeros.
In the B8ZS format, a string of eight consecutive zeros is replaced with a substitute string of pulses containing an intentional bipolar violation. The B8ZS code substitutions provide high pulse density so that the receiving equipment is able to maintain synchronization with the received signal.

1.6 Applications / Capabilities
In the following example, the MULTIPLEXER UNIT utilizes an optical fiber connection between a pair of units to provide 4, 8, 12 or 16 channels of E1, T1, Datacom, or
1 to 4 channels of Ethernet Bridge between the units.
The timing scheme for the typical point-to-point application would set all connected
E1 or T1 equipment to recovery (receive timing from the MULTIPLEXER UNITs ).

Chapter 2. Port Card Overview
2.1 Introduction
This chapter provides brief descriptive over-view of the available 4-Channel Port
card options. Detailed specifications are in Chapter 1, while removal and replacement procedures are detailed in Chapter 3. Unit configuration is all covered in Chapter 4. The cards are NOT designed to be "hot" swappable, therefore make sure the MULTIPLEXER
UNIT chassis is powered off before replacing a card or pulling it from the chassis. Removal and installation of 4-Channel Port Cards with the rack chassis under power is NOT
RECOMMENDED and will definitely effect the operation of the other 4-Channel Port
Cards (and possibly cause permanent damage to the unit).
2.2 Port Card Overview
The 4-Channel Port Cards for the MULTIPLEXER UNIT are modular PCAs which slide into the MULTIPLEXER UNIT chassis, and interface with the internal "main board".
The main board provides an interface connection to the 4-Channel Port Cards for power, data connection and other logic (for local management terminal and optional SNMP).
2.3 4 x E1 I/F Module Overview
The 4 x E1 4-Channel Port Cards for the MULTIPLEXER UNIT are modular PCAs which slide into the MULTIPLEXER UNIT chassis and provide four completely independent G.703 E1 interfaces. The module is available in two options. One, with 4 pairs of BNC connectors for 75 Ohm unbalanced connections and the other with four RJ-45 jacks for 120 Ohm balanced connections.
2.4 4 x T1 I/F Module Overview
The 4 x T1 4-Channel Port Cards for the MULTIPLEXER UNIT are modular PCAs which slide into the MULTIPLEXER UNIT chassis and provide four completely independent T1(DS1) interfaces. The module is available with four RJ-45 jacks for 100
Ohm balanced connections.
2.5 External Clock Overview
The MULTIPLEXER UNIT is available with an external clock option that allows the unit to be synchronized with external clocks or equipment. The MULTIPLEXER UNIT may receive an external clock source from E1 PCM, E1 TTL, T1 PCM or T1 TTL signal sources. Additionally, the option includes its own precision crystal based clock. The external clock is received via an RJ-45 jack from the rear panel.

Chapter 2. Port Card Overview
2.7 Ethernet Bridge Module Overview
When the MULTIPLEXER UNIT is ordered with an ET100 Port Card option, a
Single-Channel Bridge Port Card is supplied. Complete bridging functions are provided.
BRIDGE FEATURES
10BASE-T/100BASE-TX, Full Duplex or Half Duplex
HP Auto-MDIX, detects and corrects crossed cables
IEEE 802.3x flow control
Real-time filtering with 256 address tables
Automatic address learning, aged and deleted with 5 minutes
Up to 340 packet-buffering capacity
Auto padding undersize packets to meet the minimum LAN packet size requirement
Buffering modes can be selected according to the set of WAN and LAN line speeds
Automatic TP polarity correction
BRIDGE SPECIFICATIONS
Compliance: IEEE 802.3/802.3u
Connector: Shielded RJ-45
Data Rate: 10/100Mbps; Half Duplex (20/200Mbps; Full duplex)
Filtering and Forwarding: 90,000 packets/sec
Delay: 1 frame
WAN Protocol: HDLC
Filter:
When this feature is disabled (DIP1-1 OFF), all frames are passed transparently. In this configuration, the ET100 acts as an Ethernet repeater. When the filter is enabled (DIP-1 ON), frame destinations are tested against the internal MAC address table. Filtering enabled is the normal selection for Bridging.
Auto Negotiation:
When this feature is disabled (DIP1-3 ON), the LAN configuration is defined by the Duplex
(DIP-4) and Speed (DIP-5) settings. This is the preferred method of configuration, but requires the specific knowledge of the capabilities of the device to which the bridge is connected. Failure to make the proper Ethernet settings can result in reduced LAN performance or in worst case, no LAN function at all. When Auto Negotiation is enabled (DIP-3 OFF), by default, the bridge will try to determine the proper speed and duplexity of the connected device. If the negotiation fails, as it will with a legacy device that doesn't support auto-negotiation, the settings will fallback to 10Mpbs speed and Half Duplex for compatibility.
2-7
FMUX-01Mar 2003
Chapter 2. Port Card Overview
Duplex:
The original specifications for Ethernet did not allow any bi-directional transmissions. The
Ethernet operated in a half duplex mode. Modern Ethernet has the ability to operate in Full duplex mode which essentially doubles the throughput from 10Mbps to 20Mbps on 10Base-T or from
100Mbps to 200Mbps on 100Base-TX. Using this setting requires connection to equipment which also supports Full duplex Ethernet. Setting DIP-4 OFF will enable this Full duplex mode. However, if Auto-negotiation is enabled (DIP-3 OFF), then this switch's setting is ignored.
Speed:
DIP-5 is used to set the Ethernet speed at 10Mbps (10Base-T) or 100Mbps (100Base-TX).
When set ON, the Ethernet connection will operate in the slower 10Base-T speed. When DIP-5 is set OFF, the Ethernet connection will operate at 100Base- TX speed. However, if Auto-negotiation is enabled (DIP-3 OFF), then this switch's setting is ignored.
Auto MDI:
Auto MDI is a new Ethernet feature which allows Ethernet connections between MDI devices and/or MDI-X devices (HUBs) all using only straight thru, one-to-one, UTP connections.
When DIP-6 is ON, this feature is enabled. When this feature is disabled (DIP-6 OFF), the device becomes MDI only and requires a crossover UTP cable to connect to another MDI device (such as
PCs). Straight cable connections are used for connecting to MDI-X devices such as HUBs.

Chapter 3. Installation
3.1 General
This chapter explains in detail the requirements and procedures for the installation of the MULTIPLEXER UNIT Standalone/Rack Mount Fiber Optical Multiplexer.
3.2 Site Preparation
Install the MULTIPLEXER UNIT within reach of an easily accessible grounded AC outlet. The outlet should be capable of furnishing 90 to 250 VAC (20 to 60 VDC for DC supply). Allow at least 10cm (4 inch) clearance at the rear and front of the MULTIPLEXER
UNIT for signal lines and interface cables.
3.3 Mechanical Assembly
The MULTIPLEXER UNIT is designed for rack mount installation and only requires
1U space (1 3/4") in a standard EIA 19 inch rack. It is highly recommended that the unit be placed in a rack. The MULTIPLEXER UNIT may or may not be delivered completely assembled. No provision is made for bolting the MULTIPLEXER UNIT to a tabletop.

Chapter 3. Installation
3.4 Electrical Installation
3-4-1. Power connection
For a model with AC power supply, AC power (90~250VAC) is supplied to the
MULTIPLEXER UNIT through a standard IEC 3-prong receptacle, located on the rear of the chassis. For a model with DC power supply, DC –48V (20~60VDC) is connected to the terminal block, observing the proper polarity. In the AC/DC model, both IEC receptacle and
DC terminal block are provided for dual power operation. The MULTIPLEXER UNIT should always be grounded through the protective earth lead of the power cable in AC installations, or via the frame ground connection for DC installations.

3.5 Removal/Replacement Procedures
3-5-1. Optical Module Removal / Replacement
****CAUTION**** All removal/replacement procedures must be done with all power sources disconnected.
The optical interface is installed into the front of the MULTIPLEXER UNIT. The front plane of the internal mainboard provides both DC power to the optical interface card and routes signals from the card to the multiplexing/de- multiplexing circuitry. Two interface connector groups are provided for connection to either the primary optical transmit and receive pair or to the redundant optical transmit and receive pair (if the optical interface card as the redundant optical option). From here, the de-multiplexed signals are sent to the individual 4-CHANNEL Card module/channel installed in the rear of the unit (see 3-5-2 for removal/replacement procedures).
To remove the interface module, remove the two upper and one lower flat head screws using a No.2 Philips head screwdriver. Save the screws. Then gently pull the card straight forward to avoid binding. The card is only held by the friction of the connector. To install the optical module, reverse the procedure, taking care when seating the module to avoid connector damage. Gently, don't force it! Re- install the three flathead screws and don't over-tighten.

All 4-Channel Port Cards install into the rear of the MULTIPLEXER UNIT. The channel connector is held by two "thumb" screws. Loosen both thumb screws (use a flat blade screwdriver if they are too tight), then remove the connector adapter by gently pulling straight back. The 4-Channel Port cards are held in by three small flathead screws. Using a
No.2 Philips screwdriver, remove the two upper and one lower screw, then pull the module straight out (refer to the pictures below). To install the 4-Channel Port module, reverse the procedure, taking care when seating the module to avoid connector damage. Gently seat it, do not force it! Re-install the three flathead screws and do not over-tighten. Then re- install the appropriate channel adapter and tighten the thumb screws gradually and evenly.
Tightening by hand is sufficient.

4.3 Terminal Mode Operation
The MULTIPLEXER UNIT Control Port (labeled RS-232 CONSOLE on the front panel) is a console terminal port designed to facilitate setup of all parameters through the use of a standard text based terminal or any terminal emulation program running on a
Personal Computer.
4-2 Terminal Connection
A notebook computer has become an invaluable tool of the Systems Engineer.
Connection to the computer is very straight forward. The only other hardware required is a
RJ-45 to DB9F adapter cable (see page 1-6 for pinout). The MULTIPLEXER UNIT's RS-
232 Console port acts as a DCE to the PC's DTE communications port. A convenient application, provided with the Microsoft Windows
®
98/NT/2K operating systems, is
"HyperTerminal

Chapter 6. SNMP Operation
6.1 General
The Simple Network Management Protocol (SNMP) is one of many protocols in the
Internet Protocol (IP) suite. SNMP is the protocol recommended specifically for the exchange of management information between hosts residing on IP networks. Network management allows you to monitor and control network devices remotely using conventional computer network technology.
The SNMP management functions of the MULTIPLEXER UNIT are provided by an internal SNMP agent, which utilizes out-of-band communication over standard 10Base-T or
100Base-TX Ethernet. The SNMP agent is compliant with the SNMPv1 standard. SNMP communication uses the User Datagram Protocol (UDP). UDP is a connectionless transport protocol, part of the IP suite. The SNMP application uses an asynchronous command/response polling protocol and operates at the OSI Layer 7 (Layer 7 is the
Application Layer. Other IP applications that operate at this layer are FTP, Telnet, SMTP, etc.). All management traffic is initiated by the SNMP-based network management station.
Only the addressed managed entity (agent) answers the polling of the management station
(except for trap messages).
6.2 SNMP Operations
The SNMP protocol includes four types of operations:
getRequest Command for retrieving specific value of an "instance"
from the managed node. The managed node responds
with a getResponse message.
getNextRequest Command for retrieving sequentially specific
management information from the managed node.
The managed node responds with a getResponse
message.
setRequest Command for manipulating the value of an "instance"
within the managed node. The managed node responds
with a getResponse message.
trap Management message carrying unsolicited
information on extraordinary events (that is, events
which occurred not in response to a management
operation) reported by the managed node.
6-1
FMUX-01Mar 2003
Chapter 6. SNMP Operation
6.3 The Management Information Base
The management information base (MIB) includes a collection of managed objects.
Managed objects are defined as parameters that can be managed, such as specific information on device configuring or on performance statistics values.
The MIB includes the definitions of relevant managed objects (MIB variables) for the specific node. Various MIB's can be defined for various management purposes, types of equipment, etc. The management data itself is a collection of integer, string and MIB address variables that contain all the information necessary to manage the node.
A leaf object's definition includes the range of instances (values) and the "access" rights:
Read-only Instances of an object can be read, but cannot be set.
Read-write Instances of an object can be read or set.
Write-only Instances of an object can be set, but cannot be read.
Not accessible Instances of an object cannot be read, nor set.
6.4 MIB Structure
The MIB has an inverted tree- like structure (root over leaves), with each definition of a managed instance forming one leaf, located at the end of a branch of that tree. Each "leaf" in the MIB is reached by a unique path, therefore by numbering the branching points, starting with the top, each leaf can be uniquely defined by a sequence of numbers. The formal description of the managed objects and the MIB structure is provided in a special standardized format, called Abstract Syntax Notation 1, or ASN.1 (pronounced A-S-N dot one).
Since the general collection of MIB's can also be organized in a similar structure, under the supervision of the Internet Activities Board (IAB), any parameter included in a
MIB that is recognized by the IAB is uniquely defined.
To provide the flexibility necessary in a global structure, MIB's are classified in various classes (branches), one of them being the experimental branch, another being the management (mgmt) branch, and yet another the group of private (enterprise-specific) branch. Under the private enterprise-specific branch of MIB's, each enterprise
(manufacturer) can be assigned a number, which is its enterprise number. The assigned number designates the top of an enterprise-specific sub-tree of non-standard MIB's. Within this context, CTC Union has been assigned the enterprise number 4756.
6-2
FMUX-01Mar 2003
Chapter 6. SNMP Operation
Under this scheme, the path to CTC Union's Enterprise branch would be:
iso(1).org(3).dod(6).internet(1).private(4).enterprises(1).ctcu(4756)
Enterprise-specific MIB's are published and distributed by their creators, who are responsible for their contents. Specific information regarding the CTC Union's sub-tree are available from CTC Union's Research and Development Division.
The MIB supported by the MULTIPLEXER UNIT SNMP Agent follows RFC 1158
(MIB-II standard).
6.5 SNMP Communities
To enable the delimitation of management domains, SNMP uses "communities". Each community is identified by a name, which is an alphanumeric string of up to 255 characters defined by the user. Any SNMP entity (this term includes both managed nodes and management stations) is assigned by its user a community name. In parallel, the user defines for each SNMP entity a list of the communities which are authorized to communicate with it, and the access rights associated with each community (this is the
SNMP community name table of the entity).
In general, SNMP agents support two types of access rights:
Read-only the SNMP agent accepts and processes only SNMP getRequest
and getNextRequest commands from management stations
which have a read-only community name.
Read-write the SNMP agent accepts and processes all the SNMP
commands received from a management station with a read-write
community name. SNMP agents are usually configured to send traps to
management stations having read-write communities.
6.6 Configuring the SNMP Agent
The agent for the MULTIPLEXER UNIT resides in the SNMP option card installed in the MULTIPLEXER UNIT. Configuration of the agent is accomplished via the RS-232
Control Port of the MULTIPLEXER UNIT. From the Define System Parameter menu select "9", SNMP Agent.
