T1/E1 Small Module

Avaya 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 2330/4134 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.
Important:
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.
This limitation does not apply to the Secure Router 2330.
The following figures show the two types of T1/E1 Small Modules.
