Step 4—Commissioning the T1 Controllers
Configure the T1 controllers to allow calls to come into the access server. You must specify the
following information for each controller: framing type, line code type, clock source, and timeslot
assignments.
Configure
To configure the controllers, use the following commands beginning in global configuration mode:
Step Command Purpose
1 hq-sanjose(config)# isdn switch-type primary-ni Enter your telco’s switch type.
This example uses primary national ISDN 1.
2
hq-sanjose(config)# controller t1 0
Enter controller configuration mode for the
first T1 controller, which is 0. The controller
ports are labeled 0 through 3 on the quad
T1/PRI card.
3
hq-sanjose(config-controller)# framing esf
Enter the T1 framing type.
This example uses extended super frame.
4
hq-sanjose(config-controller)# linecode b8zs
Enter the T1 line code type.
This example uses B8ZS.
5
hq-sanjose(config-controller)# clock source line primary
Configure the access server to get its primary
clocking from the T1 line assigned to
controller 0.
Line clocking comes from the remote switch.
6
hq-sanjose(config-controller)# pri-group timeslots 1-24
Assign all 24 T1 timeslots as ISDN PRI
channels
1
.
1. After you enter this command, a D-channel serial interface is instantly created (for example S0:23, S1:23, and so on) in the configuration file as well as the
individual B-channel serial interfaces (for example S0:0, S0:1, ...). The D-channel interface functions like a dialer for all the 23 B channels using the controller.
7
hq-sanjose(config-controller)# exit
Exit back to global configuration mode.
8
hq-sanjose(config#) controller t1 1
hq-sanjose(config-controller)# framing esf
hq-sanjose(config-controller)# linecode b8zs
hq-sanjose(config-controller)# clock source line secondary
hq-sanjose(config-controller)# pri-group timeslots 1-24
hq-sanjose(config-controller)# exit
Configure the second controller, controller
T1 1.
Set the clocking to secondary. If the line
clocking from controller T1 0 fails, the access
server will receive its clocking from controller
T1 1.
9
hq-sanjose(config#) controller t1 2
hq-sanjose(config-controller)# framing esf
hq-sanjose(config-controller)# linecode b8zs
hq-sanjose(config-controller)# clock source internal
hq-sanjose(config-controller)# pri-group timeslots 1-24
hq-sanjose(config-controller)# exit
hq-sanjose(config#) controller t1 3
hq-sanjose(config-controller)# framing esf
hq-sanjose(config-controller)# linecode b8zs
hq-sanjose(config-controller)# clock source internal
hq-sanjose(config-controller)# pri-group timeslots 1-24
hq-sanjose(config-controller)# exit
hq-sanjose(config#)
Configure the remaining two controllers.
Set both clocking entries to internal.
The primary and secondary clock sources
have already been assigned.
