Chapter 6 Configuring the MWR 1941-DC in a Cell Site DCN
Configuring the 1 T3/E3 Module
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
Note for complete information on configuring the Clear Channel 1 T3/E3 module, see the
Clear
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.
Note
When used with the MWR 1941-DC router, the NM-1T3/E3 supports line rate throughput for traffic
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
•
Configuring DSU Mode and Bandwidth for T3
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
“Verifying the Version of Cisco IOS Software” section on page 6-3
.
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.
Note
The autoconfig/setup utility does not support configuring the card type for the T3/E3
network module.
