This completes the procedure for creating a basic channelized T1 configuration. Proceed to the
"Checking the Configuration" section on page 28 to check the interface configuration using show
commands. For additional information about configuring channelized T1 interfaces, refer to the
publications Wide-Area Networking Configuration Guide and Wide-Area Networking Command
Reference.
24 Channelized T1 Port Adapter Installation and Configuration
Use the no shutdown and exit commands respectively to reenable the interface and
return to configuration mode as follows:
Router(config-if)# no shutdown
Router(config-if)# exit
Router(config)#
%LINEPROTO-5-UPDOWN: Line protocol on Interface Serial3/1/1:0,
changed state to up
%LINK-3-UPDOWN: Interface Serial3/1/1:0, changed state to up
Repeat Step 6 through Step 9 for additional channel groups and timeslots.
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 3/1/1
Router(config-controller)# channel-group 1 timeslots 2,6,8-24
Router(config-controller)#
Router(config-controller)# interface serial 3/1/1:1
Router(config-if)# shutdown
Router(config-if)# exit
Router(config)#
%LINEPROTO-5-UPDOWN: Line protocol on Interface Serial3/1/1:1, changed state to
down
%LINEPROTO-5-UPDOWN: Interface Serial3/1/1:1, changed state to administratively
down
After including all of the configuration commands, to complete the configuration, press
Ctrl-Z (hold down the Control key while you press Z) or enter end to exit configuration
mode and return to the EXEC command interpreter prompt as follows:
Router(config)#
Ctrl-Z
Router#
Write the new configuration to memory as follows:
Router# copy running-config startup-config
[OK]
Router#
The system displays an OK message when the configuration is stored.
Exit the privileged level and return to the user level by entering disable at the prompt as
follows:
Router# disable
