Chapter 4 Configuring the Multichannel DS1/PRI Interfaces
Configuring the Interfaces
In the example that follows, 32-bit CRC is specified:
Router(config-if)# crc 32
The preceding command example applies to all systems in which the multichannel DS1/PRI port adapter
is supported. Use the no crc 32 command to disable 32-bit CRC and return the interface to the default
16-bit CRC (CRC-CITT) setting.
is supported. Use the no crc 32 command to disable 32-bit CRC and return the interface to the default
16-bit CRC (CRC-CITT) setting.
When you have finished, press Ctrl-Z—hold down the Control key while you press Z—or enter end or
exit to exit configuration mode and return to the EXEC command interpreter prompt. Then write the new
configuration to NVRAM using the copy running-config startup-config command.

Customizing the Multichannel DS1/PRI Port Adapter
You can customize the DS1/PRI port adapter. The features you can customize have default values that
will probably suit your environment and not need to be changed. However, you might need to enter
configuration commands, depending on the requirements for your system configuration and the
protocols you plan to route on the interface. Perform the tasks in the following sections if you need to

Configuring Multichannel T1 Interfaces
Following are instructions for a basic multichannel T1 configuration (enabling a controller and
specifying IP routing). You might also need to enter other configuration subcommands, depending on
the requirements for your system configuration and the protocols you plan to route on the interface. For
complete descriptions of configuration subcommands and the configuration options available, refer to
the publications listed in the

The channel groups must be mapped before the multichannel DS1/PRI controller can be configured. The
following are controller commands used to map the channel group (the default variable is listed first):
