Specify the controller's linecode format by entering the linecode command:
Step 5
Router(config-controller)# linecode b8zs
Specify a channel group and map timeslots to the channel group by entering the
Step 6
channel-group command. The following example specifies channel group 0 and maps
timeslots 1, 3 through 5, and 7 to channel group 0:
Router(config-controller)# channel-group 0 timeslots 1,3-5,7
Router(config-controller)#
%LINEPROTO-5-UPDOWN: Line protocol on Interface Serial1/1:0,
changed state to down
%LINK-3-UPDOWN: Interface Serial1/1:0, changed state to up
Each channel group is presented to the system as a serial interface that can be
Note
configured individually.
Step 7 If IP routing is enabled on the system, assign an IP address and subnet mask to the
channel group with the interface and ip address commands as follows:
Router(config-controller)# interface serial 1/1:0
Router(config-if)# ip address 10.1.15.1 255.255.255.0
Router(config-if)#
Add any additional configuration commands required to enable routing protocols and
Step 8
adjust the interface characteristics.
Use the no shutdown and exit commands respectively to reenable the interface and
Step 9
return to configuration mode as follows:
Router(config-if)# no shutdown
Router(config-if)# exit
Router(config)#
%LINEPROTO-5-UPDOWN: Line protocol on Interface Serial1/1:0,
changed state to up
%LINK-3-UPDOWN: Interface Serial1/1:0, changed state to up
Step 10 Repeat Step 6 through Step 9 for additional channel groups and timeslots.
Step 11 After configuring additional channel groups and timeslots, map all unused timeslots to an
unused channel group and shut down the unused channel group by entering the
channel-group and shutdown commands, respectively.
In the following example, unused timeslots 2, 6, and 8 through 24 are mapped to unused
channel group 1, and channel group 1 is shut down:
Router(config)# controller t1 1/1
Router(config-controller)# channel-group 1 timeslots 2,6,8-24
Router(config-controller)#
Router(config-controller)# interface serial 1/1:1
Router(config-if)# shutdown
Router(config-if)# exit
Router(config)#
%LINEPROTO-5-UPDOWN: Line protocol on Interface Serial1/1:1, changed
state to down
%LINEPROTO-5-UPDOWN: Interface Serial1/1:1, changed state to
administratively down
