E4G-400 Cell Site Aggregation Router
The E4G-400 cell site aggregation router is a compact unit (1RU or 1.75 inches high) that enables
networks to aggregate multiple Ethernet links from various cell sites and route the traffic to the mobile
core.
The E4G-400 router provides 28 Gigabit Ethernet ports and port options for up to six 10-Gigabit
Ethernet ports, as well as a 16-port T1/E1 module with pseudowire capability. The T1/E1 module is used
where 2G and 3G radios are co-located at the aggregation site, and eliminates the need for separate cell
site routers.
The Gigabit and 10-Gigabit Ethernet ports on the E4G-400 router support Synchronous Ethernet
(SyncE) and IEEE 1588v2 timing. Integrated timing connectors on the front panel provide timing based
on either the ITU-T Synchronous Ethernet (SyncE) protocol or the Precision Time Protocol based on
IEEE specification 1588v2. Four mini-BNC connectors providing Sync In/Sync Out timing interfaces and
an RJ-422 connector provides a BITS-IN interface.
The E4G-400 router has 4 shared ports. For each pair of shared ports, either the 10/100/1000BASE-T
port (RJ45) or 100/1000BASE-X (SFP) port can be used as needed.
