Figure 1: Mobile Backhaul Architecture
E4G-200 Cell Site Routers
The Extreme Networks E4G-200 routers provide 12 resilient synchronous Gigabit Ethernet ports and 16
T1/E1 ports in a compact (1RU or 1.75 inches high) unit.
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 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.
Features:
•
Management and console ports
•
Eight 10/100/1000BASE-T (RJ-45) dedicated ports
•
Four 100/1000BASE-X (SFP) ports
These ports require Extreme Networks optical modules that are designed for use within the
temperature range of the router.
•
Slot for clock module
