Cisco PA-2CT1 Installation And Configuration Manual page 23

In the following procedure, press the Return key after each configuration step:
At the privileged-level prompt, enter configuration mode and specify that the console
Step 1
terminal will be the source of the configuration commands as follows:
Router# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#
At the prompt, specify the controller to configure by entering the command controller,
Step 2
followed by t1, and chassis slot number/port adapter number/interface port number. The
example that follows is for the 2CT1 in chassis slot 3, port adapter slot 1, interface port 1:
Router(config)# controller t1 3/1/1
Specify the clock source for the controller. The clock source command determines which
Step 3
end of the circuit provides the clocking signal.
Router(config-controller)# clock source line
Note You can set the clock source to use internal clocking for testing purposes. One end
of a T1 circuit must provide the clock source.
Specify the controller's framing type by entering the framing command:
Step 4
Router(config-controller)# framing esf
Step 5 Specify the controller's linecode format by entering the linecode command:
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 Serial3/1/1:0,
changed state to down
%LINK-3-UPDOWN: Interface Serial3/1/1:0, changed state to up
Each channel group is presented to the system as a serial interface that can be
Note
configured individually.
If IP routing is enabled on the system, assign an IP address and subnet mask to the
Step 7
channel group with the interface and ip address commands as follows:
Router(config-controller)# interface serial 3/1/1:0
Router(config-if)# ip address 10.1.15.1 255.255.255.0
Router(config-if)#
Step 8 Add any additional configuration commands required to enable routing protocols and
adjust the interface characteristics.
