E4G-200 Series Cell Site Routers
There are two models in the E4G-200 series: the E4G-200 and the E4G-200-12x.
E4G-200 Cell Site Router Overview
The Extreme Networks E4G-200 router provides 12 resilient synchronous Gigabit Ethernet ports (eight
RJ-45 and four SFP) 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 E4G-200 router provides high-performance pseudowire capability, supporting both CESoPSN
(channelized) and SAToP (unframed and unchannelized) TDM services. Deployed at the cell site,
E4G-200 router collects traffic from 2G, 3G, and 4G radio towers for handoff to the mobile backhaul
over fiber or microwave.
The E4G-200 router’s extended temperature range of -40°C to +65°C allows service providers to deploy
the E4G-200 router at sites without climate control.
The E4G-200 cell site router front panel (Figure 2) has the following features:
● Alarms port implemented as a DB-15 connector.
For details about the connector, see “E4G-200 Series Connector Pinouts” on page 126.
● Management and console ports
● Eight 10/100/1000BASE-T (RJ-45) dedicated ports
