Relationship of ISDN PRI Components for T1

Note When you configure your CT1 controller for an Non-Facility Associated Signaling (NFAS) backup D channel, a

serial interface is automatically created only when your primary D channel fails.

To configure ISDN signaling, follow these steps:

Step1 Enter the enable command and password to go to privileged EXEC mode. You are in privileged EXEC mode when the

prompt changes to Gateway#.

Gateway> enable

Password: password

Gateway#

Step2 Enter global configuration mode. You are in global configuration mode when the prompt changes to Gateway(config)#.

Gateway# configure terminal

Enter configuration commands, one per line. End with CNTL/Z.

Gateway(config)#

Step3 Enter serial interface configuration mode. After configuring the CT1 controller, a corresponding D-channel serial

interface is automatically created. For example, serial interface 1/0:23 is the D channel for CT1 controller 1. You must

configure each serial interface to receive incoming signaling and send outgoing signaling.

Note On a CE1 PRI line, the serial interface for the D channel is 1/0:15.

Gateway(config)# interface serial 1/0:23

Gateway(config-if)#

Step4 Assign an IP address and subnet mask to the interface:

Gateway(config-if)# ip address 172.16.254.254 255.255.255.0

Step5 Configure 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.

Gateway(config-if)# isdn incoming-voice modem
