ETX-205A


SFP/COPPER COMBO PORTS

All ETX-205A units are equipped with

SFP/copper combo Ethernet ports, enabling flexible mixture of fiber optic and copper interfaces in one device. The SFP ports accommodate a wide range of Fast

Ethernet and Gigabit Ethernet SFP transceivers, allowing service providers to seamlessly connect customers located at different distances from the device.

TYPICAL APPLICATIONS

ETX-205A is used in the following applications:

 Ethernet demarcation device –

ETX-205A separates the service provider network, the access provider network, and the customer network, providing proactive service monitoring and easy fault localization throughout the entire network (see

Figure 1

)

 Mobile demarcation device – ETX-205A is installed at the operator tower and controller sites equipped with an

Ethernet port, connecting the NodeB or eNodeB to the packet network, providing sophisticated traffic management and service assurance capabilities, including proactive service monitoring and fault identification throughout the entire network (see

Figure 2

).

FLEXIBLE TRAFFIC MAPPING

Traffic is mapped to the Ethernet flows using very flexible classification criteria based on incoming port (port-based all-to-one bundling), VLAN ID, VLAN priority, IP precedence, DSCP, Ethertype, and IP/MAC source/destination address.

Classification is defined for both VLAN tagged as well as untagged traffic.

The device can be configured to pass through Layer-2 control frames (including other vendors’ L2CP frames, and with optional MAC change) across the network, to peer supported protocols

(IEEE 802.3-2005 and LACP), or to discard the L2CP frames.

HIERARCHICAL QUALITY OF SERVICE

(H-QOS)

Different service types require different levels of QoS to be provided end-to-end.

QoS can be defined per subscriber as well as per service. QoS has three aspects: rate limitation, traffic shaping, and traffic prioritization.

Traffic policing is applied per flow or group of flows, and operates according to the dual token bucket mechanism based on user-configurable CIR + CBS and EIR + EBS.

Traffic can be limited to the line rate or the data rate.

Every flow per EVC or EVC.cos has its own queues and scheduler supporting strict priority and weighted fair queues (WFQ).

Queue blocks of eight queues per EVC are scheduled and shaped, forming an H-QoS model with shaped services and prioritized classes of service. The WRED mechanism is used for smart packet drop.

The VLAN priority bit in Ethernet frames can be modified at network ingress according to the ‘color’ of the frame. This allows service consistency and QoS continuity across color-aware (drop eligible enabled) as well as color-unaware networks.

HARDWARE-BASED ETHERNET OAM

Featuring ultra fast, hardware-powered processing, ETX-205A performs OAM and

PM measurements in line rate with maximum precision, offering the following powerful benefits:

 Immediate detection of loss of continuity (LOC), ensuring under 50 ms protection switching

 Highly accurate frame loss measurements of live traffic

 Flow-level (per CoS) monitoring, enabling simultaneous processing of multiple OAM sessions with E-LAN and

E-TREE support

 Non-disruptive MAC and IP level loopback testing of network integrity.

ETX-205A provides these types of

Ethernet OAM:

 Single-segment (link) OAM according to IEEE 802.3-2005 for remote management and fault indication, including remote loopback, dying gasp with SNMP trap, and MIB parameter retrieval. Active and passive mode are supported.

 End-to-end connectivity OAM based on IEEE 802.1ag-D8 that enables

Ethernet service providers to monitor their services proactively and guarantee that customers receive the contracted SLA

 End-to-end service and performance monitoring based on ITU-T Y.1731.

Fault monitoring and end-to-end performance measurement include delay, delay variation, frame loss and availability.

Data Sheet

.

FAULT PROPAGATION

The unit provides a user-configurable fault propagation mechanism in the network-to-user or user-to-network direction.

When a link failure is detected or OAM failure received, ETX-205A can shut down the affected port or forward the OAM failure message. The fault propagation mechanism enables routers and switches connected to both ends of the link to reroute the traffic to the redundancy path.

RFC-2544

The device provides a built-in RFC-2544 wire-speed traffic generator and analyzer for unidirectional and bidirectional testing of throughput, latency, and frame loss.

Based on standard OAM messages, the tests can be simultaneously performed over multiple flows, at the EVC.CoS level.

Enhanced RFC-2544 functionality provides service-oriented KPI analysis. SLA conformance is measured per service bandwidth and packet size, within a user-defined amount of time, for faster service introduction.

NETWORK INTERFACE RESILIENCY

ETX-205A provides the following network interface protection modes:

 802.3ad Link aggregation (LAG), providing 1:1 link protection with Link

Aggregation Control Protocol (LACP) support

 Dual homing (1:1), allowing ETX-205A units to be connected to two different upstream devices.

FLOW LEVEL RESILIENCY

ETX-205A applies standard ITU-T G.8031

Ethernet Linear Protection switching for fast protection of one or more EVCs from end to end. The standard implementation ensures interoperability with third-party devices. With standard APS functionality,

Ethernet OAM messages provide bandwidth-efficient unidirectional or bidirectional 1:1 protection

The EVC protection path can be configured on the same network port, enabling the transport network to provide an alternative path for the working and protecting paths. It can also be configured on separate network ports, adding protection at the access layer and enabling load balancing on network interfaces by splitting traffic between the two network ports.

The performance of the hardware-based

Ethernet OAM together with protection switching for physical layer failure ensures fast protection in any scenario.

The flow level protection provides a full set of manual commands for maintenance purposes.

INTEGRATED SMART SFP

Integrated management of MiRICi smart

SFPs provides TDM (E1/T1/E3/T3/

OC-3/STM-1) connectivity over PDH or

SDH legacy networks. ETX-205A supports configuration and statistic collection for the smart SFP TDM port.

MOBILE BACKHAUL SYNCHRONIZATION

ETX-205A implements the RAD SyncTop™ synchronization suite (see

Figure 2

), allowing cellular backhaul providers to meet the necessary synchronization requirements without the need to invest in dedicated timing equipment at every base station. ETX-205A timing features include:

 Synchronous Ethernet (SyncE) per

ITU-T G.8261-G.8264

 IEEE 1588v2 Precision Time Protocol transparent clock with hardware-based time stamping and hardware provisioning for PTP slave functionality

 External clock in/out interfaces (T3/T4) supporting 2MHz, 2M bits, and T1 frequencies

 Primary/secondary clock redundancy with stratum 3/3E holdover performance.

LAYER-2/ LAYER-3 LOOPBACK WITH

MAC AND IP ADDRESS SWAPPING

Layer-2 and/or layer-3 network integrity can be tested by a non-disruptive loopback performed per flow, with swapping of MAC address and optionally

IP address. When the loopback is activated, ETX-205A exchanges the source and destination MAC/IP addresses of the incoming packets. This loopback passes through Ethernet bridges (MAC address) and routers (IP address).

DYING GASP

ETX-205A reports power failures to defined network management stations by sending an IEEE 802.3-2005 message or

SNMP trap, thus enabling the unit to properly disconnect from the network with notification of the reason for the service problem.

TRAP SYNCHRONIZATION

Traps are sent with sequence IDs to network manager groups, to enable the managers to detect when traps are lost and request the traps be sent again.

MANAGEMENT

The unit can be managed using the following ports and applications:

 Local management via an ASCII terminal connected to the RS-232 port

 Out-of-band management via a dedicated management port.

 Remote inband management via user or network ports routed via separate

VLANs, Telnet, or an SNMP-based management system.

SECURITY

The following security protocols are provided by ETX-205A to ensure client server communication privacy and correct user authentication:

 SNMPv3

 RADIUS (client authentication)

 TACACS+ (client authentication, authorization, and accounting)

 SSH (secure shell communication session)

 SFTP (secure file transfer).

ZERO TOUCH PROVISIONING

IP address, IP mask, default gateway, and link to configuration manager can be automatically obtained using standard

DHCP client functionality. This enables seamless node setup and configuration for quick and scalable network setup and deployment as well as configuration consistency when nodes must be replaced.

COMMAND LINE INTERFACE

Databases and scripts of commonly used commands can be easily created and applied to multiple units using command line interface.
