Configuring ISDN PRI
53
Cisco VGD 1T3 Voice Gateway Software Configuration Guide
For channelized T1 ISDN PRI—If you do not specify the timeslots, the specified controller is configured
for 23 B channels and 1 D channel. B channel numbers range 1 to 23; channel 24 is the D channel for
T1. Corresponding serial interface numbers range 0 to 23. In commands, the D channel is interface
serial slot/ds3 port/ds1 port:23—for example, interface serial 4/0:1:23.
Command Purpose
Step 1
Router> enable
Enters privileged EXEC mode.
Step 2
Router# configure terminal Enters global configuration mode. You are in
global configuration mode when the prompt
changes to
Router(config)#.
Step 3
Router(config)# isdn switch-type
switch-type
Selects a service provider switch type that
accommodates PRI. (See
Table 3 for a list of
supported switch type keywords.)
Step 4
Router(config)# controller t1 1/0:1
Specifies T1 feature card slot, port number, and
channel. On the CT3 feature card, the port number
is always 0. The T1 channel values range from
1 to 28.
After you configure the T1 controller, a
corresponding D-channel serial interface is
created instantly. See the
“Configuring the D
Channels for ISDN Signaling” section on page 55
to learn how to configure your D channel.
Step 5
Router(config-controller)# framing esf Enters framing type for the CT3 feature card.
Step 6
Router(config-controller)# linecode b8zs
Defines the line code as binary 8 zero substitution
(B8ZS) for the T1 or CT3 feature card.
Step 7
Router(config-controller)# pri-group
[ timeslots range ]
1
1. For T1, timeslots range 1 to 24. You can specify a range of timeslots (for example, pri-group timeslots 12-24) if other
timeslots are used for non-PRI channel groups.
Configures ISDN PRI.
If you do not specify the timeslots, the controller
is configured for 23 B channels and 1 D channel.
Step 8
Router(config-controller)# Ctrl-Z
Returns to privileged EXEC mode.
