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 terminal will be
Step 1
the source of the configuration commands as follows:
Router# configure t
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#
Step 2
Identify the ISDN switch type. In the following example, the switch primary-net5 (a switch for the
European Community) is identified as the switch type:
Router(config)# isdn switch-type primary-net5
Note
The ISDN switch type that you identify is for all ISDN interface ports installed in the
router.
Step 3
Specify the controller to configure by entering the command controller followed by e1, and chassis slot
number/port adapter number/interface port number. The example that follows is for the 2CE1 in chassis
slot 3, port adapter slot 1, interface port 1:
Router(config)# controller e1 3/1/1
Step 4
Specify the controller's framing type by entering the framing command as follows:
Router(config-controller)# framing crc4
Step 5
Specify the controller's linecode format by entering the linecode command as follows:
Router(config-controller)# linecode hdb3
Step 6
Map timeslots to the controller's PRI group by entering the pri-group command. The following example
shows PRI-group timeslots 1, 3 through 5, and 7 (the B channels) selected and mapped to timeslot 16
(the D channel), which is recognized by the system as timeslot 15:
Router(config-controller)# pri-group timeslots 1,3-5,7
Router(config-controller)#
%LINEPROTO-5-UPDOWN: Line protocol on Interface Serial3/1/1:15,
changed state to down
%LINK-3-UPDOWN: Interface Serial3/1/1:15, changed state to up
In the above example, the line-protocol status for timeslot 16 (listed in the output as
Note
timeslot 15) represents the entire PRI group.
Each PRI group is presented to the system as a serial interface that can be configured
individually.
Step 7
If IP routing is enabled on the system, assign an IP address and subnet mask to the PRI group with the
interface and ip address commands as follows.
