Overview

For service providers, revenue growth is increasingly driven by 3G and eventually 4G mobile

services that provide access to compelling smartphone, and tablet-based, and other mobile

applications. The challenge in designing true 4G mobile backhaul is to build a foundation

that protects existing investments in 2G and 3G services, provides a superior subscriber

experience, prepares for future 4G service requirements, and minimizes costs. This challenge

can be met by deploying a true 4G mobile backhaul network with three key ingredients:

resiliency, synchronization and performance.

Extreme Networks E4G-200 router is a carrier-grade Ethernet platform that provides a

seamless migration path from TDM circuits to Ethernet services for mobile operators and

creates a fundamental Ethernet infrastructure capable of scaling to the needs of 2G, 3G and

4G mobile networks.

Product Description

The Extreme Networks E4G-200 Cell Site Router delivers Ethernet, IP/MPLS and pseudowire

capabilities in a compact 1RU form factor. The E4G-200 provides mobile operators the

ability to manage and aggregate TDM and Ethernet services and their associated protocols

onto an economical and ecient Ethernet mobile backhaul infrastructure.

The Extreme Networks E4G-200 Cell Site Router (CSR) is where 4G backhaul begins and

where the T1/E1 pseudowire circuit for 2G/3G is also initiated. Installation is in or very near to

the base station tower. 2G and 3G base stations use T1/E1 for backhaul connectivity and 4G

base stations connect directly to the cell site router via Ethernet. The E4G-200 provides the

necessary interfaces for 2G, 3G, and 4G base stations while still meeting the demands of its

installation environment, in a design that is very compact (less than 10 inches/24 cm deep),

and features an extended temperature range.

The Extreme Networks E4G-200 router is designed for services running over an Ethernet

and IP/MPLS infrastructure. The E4G-200 is designed to backhaul 2G, 3G and 4G mobile

trac, using a single backhaul network instead of a multiple backhaul networks which

translates into an economical deployment model. Service providers, energy utilities,

Highlights

The E4G-200 enables service providers to

provide Ethernet/IP services cost-eectively at

any cell site, including optional TDM pseudow-

ires and deployments of 4G base stations. This

flexibility gives service providers the ability to

deploy revenue-generating services at 2G/3G

cell sites and allows for 4G deployments and

new Ethernet/IP services.

Extreme Networks Data Sheet: E4G-200 Cell Site Router Technical Specifications

With an extended temperature range of -40°C to +65°C, service providers

can deploy the E4G-200 router at sites without climate control, enabling

more sites to convert to packet-based backhaul, reducing CapEx and OpEx,

and allowing Ethernet/IP services to be delivered to a larger target market.

Twelve active GbE ports allow service providers to connect more 4G base

stations for growth and to support other Ethernet/IP equipment local to

the cell site.

Mobile backhaul networks require accurate timing. The E4G-200 provides

today’s existing TDM timing on it T1/E1 ports as well as the Ethernet-based

timing—both IEEE 1588v2 and SyncE—on its Ethernet ports.

Extreme Networks supports EAPS as well as the G.8032 Ethernet Ring

Protection standard.

Support for IEEE 802.3ah, IEEE 802.1ag, and ITU Y.1731 gives management

and reporting control over the Ethernet backhaul, including pseudowires to

provide integrated Ethernet OAM.

Functions in the hardware allow for mere microseconds of latency to

improve performance of latency-sensitive applications that are a part of

LTE rollouts.

Ports, services and OAM functions run at line rate with no degradation in

service when the dierent feature sets are enabled.

Extreme Networks Ethernet mobile backhaul solutions are geared towards

the unique demands of mobile operators. Our solutions oer support for

multiple generations of services. Mobile operators can lower their capital

expenses (CapEx) and operational expenses (OpEx) by reducing the

number of network elements and simplifying operations. Our solutions can

enable mobile operators to deliver a network that is geared towards the

new mobile world, providing access, awareness and control, from the cloud

to the converged edge.

transportation and government agencies can deploy Extreme Networks

E4G-200 router for mobile backhaul with the knowledge that their

deployments will have advanced services.

• With advanced routing and switching features such as MPLS, IPv6,
Ethernet OAM, and others, the E4G-200 is future proof to protect the
service provider’s investment

• Using hardware-based Ethernet OAM standards allows detailed
service assurance guarantees oerings to be oered over the
packet-based backhaul network

• E4G-200 routers allow for a cost-eective transformation path to an
Ethernet backhaul by providing E1/T1 interfaces.

• Powerful Carrier Ethernet platform in only a 1RU system, but

Key Features and Benefits

The 1RU size of the E4G-200 allows economical installation in cell site

locations where space is limited. All Extreme Networks advanced routing

and switching features, including IPv6, are available on this compact and

powerful platform.

E4G-200 optionally supports up to 16 ports for circuit emulations via

industry-standard pseudowires, allowing the transformation of TDM cell

sites to Ethernet/IP/MPLS cell sites.
