Configuring the 1 T3/E3 Module

The NM-1T3/E3 is a single port universal T3/E3 network module with integrated CSU/DSU, clear
channel, and subrate support. Channels on the network module can be configured as either T3 or E3
through Cisco IOS software and enables you to switch between T3 and E3 applications with a single IOS
command.
Note for complete information on configuring the Clear Channel 1 T3/E3 module, see the Clear
Note
Channel T3/E3 with Integrated CSU/DSU Cisco IOS Release 12.2(15)T feature module.
Caution Online insertion and removal (OIR) of the NM-1T3/E3 is not supported on the Cisco MWR 1941-DC
platform.
When used with the MWR 1941-DC router, the NM-1T3/E3 supports line rate throughput for traffic
Note
with packet sizes of 1500 bytes. For traffic with smaller packet sizes, degradation in throughput will
be seen.

Configuring the T3 Interface

To configure the T3 interface, complete the following required tasks:
•

Configuring the Card Type and Controller for a T3 Interface

When the Clear Channel T3/E3 network module is used for the first time, the running configuration does
not show the T3/E3 controller and its associated serial interface. You can use the show version command
to learn if the router recognized the T3/E3 card and was able to initialize the card properly. After the
card type is configured for the slot, the respective controller and serial interface appear in the running
configuration. See the
After the network module has ascertained that the card has been initialized properly, use the card type
command to configure the card. If the command is accepted successfully, Cisco IOS software creates a
controller and a serial interface for the card.
The autoconfig/setup utility does not support configuring the card type for the T3/E3

network module.
