The Cutter Networks ETX-2 selection tool

The RAD ETX-2 family includes several models and each of those models have numerous options. To assist you in determining the correct RAD ETX-2 for you, Cutter Networks has created the ETX-2 selection tool. Be sure to give it a try.

Key Features of ETX-2

• Feature-rich demarcation and aggregation suite, offering a complete Service Assured Access (SAA) solution
• Ideal for service providers, wholesalers, and mobile operators, seeking to deliver and monitor SLA-based MEF-certified CE 2.0 and TDM-over-PSN
• Versatile offering of multirate Ethernet over fiber, SHDSL, VDSL, GPON, PDH, and TDM, assuring unified service delivery over any access technology
• TWAMP and Layer-2 OAM, diagnostics for scalable and accurate traffic monitoring, quick fault detection, and troubleshooting of Layer-2 and Layer-3 networks

The ETX-2 carrier Ethernet demarcation device is the main component of RAD’s Service Assured Access solution, providing:

• Synchronization for mobile 2G, 3G, LTE, and LTE-A backhauling networks
• PWE functionality for mobile backhauling and business services
• Operation in diverse topologies including ring, daisy chain, and hub and spoke
• Ethernet service uniformity over multiple access technologies including GbE and 10GbE, SHDSL, VDSL, PDH, and SDH

ETX-2 is offered in a variety of product options: ETX-203AM, ETX-203AX, ETX-205A, and ETX-220A. Table 1 provides further information on the capabilities offered by each ETX-2 device

MARKET SEGMENTS AND APPLICATIONS FOR RAD ETX-2

ETX-2 is ideal for carriers, service providers, wholesale providers, and mobile operators seeking to offer unified SLA-based Ethernet business services, such as E-Line, E-LAN, E-Tree, and E-Access.

ETX-2 INTEROPERABILITY

The ETX-2 family features and services are standard based and should work with any 3rd party equipment using standard based features and services.

NETWORK TOPOLOGIES USING ETX-2

ETX-2 supports several network topologies such as linear, daisy chain, and self-healing rings (G.8032v2), working with ETX-5 or third-party Ethernet devices.

CARRIER ETHERNET 2.0 SERVICES

ETX-2 incorporates a complete set of CE 2.0-certified Ethernet service tools that allow the service provider to distinguish between high- and low-priority traffic, and optimize TCP sessions. ETX220A also provides MEF 10.3 color aware and unaware Policers, delivering high-scale multi-CoS services with hierarchical Quality of Service (HQoS). It supports advanced scheduling, WRED per CoS, shaping per EVC and port, with flexible classification rules and access lists.

MEF Services

ETX-2 delivers E-Line (EVL, EVPL), E-LAN (EPLAN, EVPLAN), E-Tree (EP-TREE, EVP-TREE), and E-Access services.

Layer-2 Control Processing

ETX-2 can be configured to forward or discard Layer-2 control frames (including other vendors’ L2CP frames).

DHCP and MLDv2 SNOOPING

With DHCP and MLDv2 snooping, multicast data is selectively forwarded only to a list of self-learned ports (per multicast group membership), instead of being flooded to all ports in a VLAN.

TDM PSEUDOWIRE

ETX205A with built-in E1 ports and ETX-2 with smart SFP (MiTOP) provide pseudowire (PWE) services. The PWs can be encapsulated using CESoPSN per IETF RFC 5086 or SAToP per IETF RFC 4553.

The ETX-2 is a great product but selecting the correct model can be difficult. Here at Cutter Networks, we have delveloped several tools to assist with this process and of course, you can also just contact us.
