Configuring ISDN PRI
Channelized T1 ISDN PRI offers 23 B channels and 1 D channel. Channelized E1 ISDN PRI offers 30 B channels and
1 D channel. Channel 24 is the D channel for T1, and channel 16 is the D channel for E1. ISDN provides out-of-band signaling
using the D channel for signaling and the B channels for user data.
For a complete description of the commands mentioned in this chapter, refer to the Dial Solutions Command Reference.

Request PRI Line and Switch Configuration from a Telco Service Provider

Before configuring ISDN PRI on your Cisco universal gateway, you must order a correctly provisioned ISDN PRI line from your
telecommunications service provider.
This process varies from provider to provider on a national and international basis. However, some general guidelines follow:
•Determine if the outgoing B channel calls are made in ascending or descending order. The CiscoIOS software default is
descending order; however, if the switch from the service provider is configured for outgoing calls made in ascending order,
the universal gateway can be configured to match the switch configuration of the service provider.
•Ask for delivery of calling line identification. Providers sometimes call this CLI or automatic number identification (ANI).
•If the gateway will be attached to an ISDN bus (to which other ISDN devices might be attached), ask for point-to-multipoint
service (subaddressing is required) and a voice-and-data line.
Configure ISDN PRI by executing the following steps:
Step1 Use the enable command and password to enter 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 Select a service provider switch type that matches your service provider switch:
Gateway(config)# isdn switch-type switch-type
