Basic Configuration Using the Command-Line Interface on the Cisco VGD 1T3 Voice Gateway
Configuring the D Channels for ISDN Signaling

Cisco VGD 1T3 Voice Gateway Software Configuration Guide
Examples
To verify your D channel configuration, enter the show interface serial command and make sure the line
protocol is up and you are using the correct IP interface. Also, make sure that excessive errors are not
being reported.
Router#
show interface serial 4/0:1:23
Serial4/0:1:23 is up, line protocol is up (spoofing)
Hardware is DSX1

0 output buffer failures, 0 output buffers swapped out
1 carrier transitions
Timeslot(s) Used:24, Transmitter delay is 0 flags
If you are having trouble, make sure the serial interface and protocol are up by entering the show
interface serial command.
Step 3
Router(config)#
interface serial 4/0:1:23
Enters serial interface configuration mode. After
you configure the T1 controller, a corresponding
D channel serial interface is automatically
created. For example, serial interface 4/0:1:23 is
the D channel for T1 controller 1. You must
configure each serial interface to receive incoming
and send outgoing signaling.
Step 4
Router(config-if)#
ip address
172.16.254.254 255.255.255.0
Assigns an IP address and subnet mask to the
interface.
Step 5
Router(config-if)#
isdn incoming-voice
modem
Configures all incoming voice calls.
Note
This command has two possible keywords:
data and modem. You must use the
modem keyword to enable both modem
and voice calls. The modem keyword
represents bearer capabilities of speech.
Step 6
Router(config-if)#
exit
Exits interface configuration mode.
