Extreme Networks E4G Series Routers

The Extreme Networks E4G router family consists of the E4G-200 cell site routers (models E4G-200 and E4G-200-12x) and the E4G-400 cell site aggregation router.

These routers provide high-bandwidth capacity, highly accurate and flexible timing, and Operations Administration and Maintenance (OAM) capabilities that support service level agreement (SLA) metrics. They support time-division multiplexing pseudowire end-to-end emulation (TDM PWE3). PWE allows the simultaneous support of multiple generations of services (2G, 3G, and 4G) over the same Ethernet backhaul network without having to remove legacy T1/E1 equipment and incur associated costs.

Note

Unless otherwise noted, the term E4G-200 refers in this document to both models in the E4G-200 series: the E4G-200 and the E4G-200-12x.

The E4G-200 cell site router collects traffic from cell site towers for handoff to the mobile backhaul network. The E4G-200 router connects to the E4G-400 cell site aggregation router, which aggregates T1, E1, and Ethernet traffic for handoff to the mobile core.
