Table 5-12 list commands used to map the channel-group, with the default variable is listed first.
Table 5-12 Channel Group Mapping Commands
Note Cisco 7000 series routers identify channel-groups as serial interfaces by slot number
(interface processor slots 0 to 4), applique (0 or 1), and channel-group number (0 to 23 for T1 and
0 to 29 for E1) in the format, slot/port:channel-group. For example, the address of the MIP installed
in interface processor slot 4, with applique 1 and channel-group 5, would be serial 4/1:5.
T1 Configuration
The following steps describe a basic T1 configuration. Press the Return key after each configuration
step.
Step 1 At the privileged-mode prompt, enter the configuration mode and specify that the console
terminal will be the source of the configuration subcommands as follows:
Router# conf t
Enter configuration commands, one per line. End with CNTL/Z. Router(config)#
Step 2 At the prompt, specify the controller to configure by entering the subcommand cont,
followed by t1, and slot/applique (interface processor slot number/applique). The example
that follows is for the MIP in interface processor slot 4, applique 1:
Router(config)# cont t1 4/1
Step 3 At the prompt, specify the clock source for the controller. The clock source command will
determine which end of the circuit provides the clocking.
Router(config-controller)# clock source line
Note The clock source should only be set to use the internal clocking for testing the network or if
the full T1 line is used as the channel-group. Only one end of the T1 line should be set to internal.

For speed, 56 is the default.

1. Number is the channel-group 0 to 23 for T1 and 0 to 29 for E1.
Timeslots list is a number between 1 to 24 for T1 and 1 to 31 for E1. It conforms to D3/D4 numbering for T1. Timeslots may be entered individually and separated
by commas or as a range that is separated by a hyphen (for example, 1-3, 8, 9-18). For E1 and T1, 0 is illegal.
Speed specifies the DSO speed of the channel-group: T1 default is 56 kbps and E1 default is 64 kbps.
channel-group number timeslots list [speed {56 | 48 |64}]
For speed, 64 is the default.
