E4G-400 Cell Site Aggregation Router

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 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-400 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 E4G-400 is a cell site aggregation router providing up to 28 GbE ports and six 10 GbE ports in a 1RU form factor. Additionally, the E4G-400 router provides an optional 16-port T1/E1 interface module to address the pseudowire capability that may be required at various points in the network (i.e. where 2G/3G cell towers are located in closer proximity to the cell site aggregation switch). The E4G-400 aggregation router offers services capacity as well as subscriber scalability through its line-rate GbE and 10 GbE performance and support for IPv6 in hardware.

Multiple resilient GbE Ethernet Transport rings can be provisioned to support thousands of cell sites due to the line-rate performance and port density of the E4G-400, and through its support for EAPS and ITU-T G.8032.

For end-to-end clock synchronization to deliver predictable multi-service performance, the E4G-400 router can be SyncE-enabled. IEEE 1588v2 is also supported, and one or both of these protocols can be utilized depending on the deployment scenario, giving mobile operators the flexibility to choose the option that best suits their needs.
