E4G-200 Cell Site Router
The Extreme Networks E4G-200 router provides 12 resilient synchronous Gigabit Ethernet ports and 16
T1/E1 ports in a compact 1RU unit. The Ethernet ports support both IEEE 1588v2 and Synchronous
Ethernet (SyncE) timing, and the T1/E1 ports support time division multiplexing (TDM) timing. The
router provides high-performance pseudowire capability, supporting both CESoPSN (channelized) and
SAToP (unframed and unchannelized) TDM services. Deployed at the cell site, the E4G-200 cell site
router collects traffic from 2G, 3G, and 4G radio towers for handoff to the mobile backhaul over fiber
or microwave.
The E4G-200 extended temperature range of -40°C to +65°C allows service providers to deploy the
E4G-200 router at sites without climate control.

These ports require Extreme Networks optical modules that are designed for use within the
temperature range of the router.
