Chapter 4 Configuring Channelized T1/E1 Interfaces
Configuring T1/E1 Interfaces
4 Specify the controller's line encoding type:
XSR(config-controller<T11/0>)#linecode b8zs
5 Specify a channel group and map timeslots to the channel group by
entering the channel-group command.
XSR(config-controller<T11/0>)#channel-group 0 timeslots 1,3-5,8
The example specifies channel group 0 and maps timeslots 1, 3
through 5, and 8 to channel group 0.
NOTE
Each channel group is represented as a serial interface and is set
individually. Channel groups are created as shown above but to configure
them you must acquire Interface Serial mode as shown below.
6 Enter the no shutdown command to enable the line.
XSR(config-controller<T11/0>)#no shutdown
7 If IP routing is enabled, assign an IP address and subnet mask to
the channel group with the interface and ip address commands:
XSR(config)#interface serial 1/0:0
That is, NIM 1, port 0, and Channel group 0.
XSR(config-if<S1/0:0>)#ip address 10.1.16.2 255.255.255.0
8 Specify the encapsulation protocol to be used over this interface.
XSR(config-if<S1/0:0>)#encapsulation ppp
In this example PPP is used.
9 Add any additional configuration commands required to enable IP- or
PPP-related protocols and functionality.
10 Use the no shutdown and exit commands to enable the interface
and return to configuration mode. Repeat the previous steps to
configure more channel groups.
XSR(config-if<S1/0:0>)#no shutdown
