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.
You can use the T1/E1 Small Modules for either data or voice connections.
You can configure each port on the 2-port T1/E1 Small Module in either
data or voice mode.
ATTENTION
Slot 2 of the Secure Router 4134 supports only one port of any WAN data Small
Module. If you install a 2-port Small Module in Slot 2, and use the Small Module
for data connections, one port only is functional (port 1).
This limitation also applies to the 2-port T1/E1 and ISDN BRI Small Modules if
they are configured for voice traffic: only port 2/1 is functional. This limitation
does not apply to FXS or FXO voice modules.
The following figures show the two types of T1/E1 Small Modules.
