Serial Small Module - Nortel Secure 4134 Installation Manual

Serial Small Module

You can install the 1- and 2-port Serial 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 Serial Small Module in this slot, one port only
is functional.
The 1-port Serial Small Module provides one external multiprotocol serial
WAN port. The port operates in either Data Terminal Equipment (DTE)
or Data Communications Equipment (DCE) mode at data rates up to 2.0
Mbps. Each serial port supports one bundle only.
The following figure shows the 1-port Serial Small Module.
