Cell Site Router


  • Low latency for LTE
  • Line rate performance
  • Compact size – 1 RU and only 10 inches/25.4 cm in depth




All Extreme Networks advanced routing and switching features, including IPv6, are available on this compact and powerful platform.

The highly scalable Extreme Networks cell site router is a new carrier-grade Ethernet platform designed to enable true 4G mobile backhaul networks through three capabilities – synchronization, resiliency, and performance. The Cell Site Router provides industry-standard pseudowires, supporting both CESoPSN (framed and channelized) and SAToP (unframed and unchannelized) TDM services. By converting TDM T1/E1 connections from 2G and 3G services over pseudowires for transport over Ethernet mobile backhaul, the cell site router enables the support of multiple generations of services over a single Ethernet mobile backhaul network.
