E4G Series Routers Hardware Installation Guide

E4G-200 Series CLK Module

An optional clock module (Figure 4) for both E4G-200 Series routers provides timing based on either of

the following protocols:

● ITU-T Synchronous Ethernet (SyncE) protocol

● Precision Time Protocol based on the IEEE specification 1588v2

The clock module has four mini-BNC connectors providing Sync In/Sync Out timing interfaces and an

RJ-45 connector that provides an RS-422 BITS-IN interface. Clock modules can be installed or removed

without powering down the router, although a system reboot is required to initialize the module.

E4G-200 Series F16T1E1 Module

The F16T1E1 module for both E4G-200 Series router provides 16 T1/E1 ports implemented as RJ-45

connectors (Figure 5. These support circuit emulations via industry-standard pseudowires, allowing the

transformation of TDM cell sites to Ethernet/IP/MPLS cell sites. T1/E1 modules can be installed

or removed without powering down the router, although a system reboot is required to initialize

the module.
