T1/E1 Small Module

Nortel offers the T1/E1 Small Module with one or two ports. The T1/E1
Small Module provides Wide Area Network (WAN) access through each of
its T1/E1 ports.
You can install the 1- and 2-port T1/E1 Small Modules in any of the Small
Module slots on the Secure Router 4134 chassis.
Slot 2 of the Secure Router 4134 supports only one port of a Small Module.
Therefore, if you install a 2-port T1/E1 Small Module in this slot, one port only
is functional.
The following figures show the two types of T1/E1 Small Modules.
