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 section, see the Cisco IOS Dial Technologies Configuration
Guide, which is available online. You can access this document at Technical Support & Documentation > Product Support >
Cisco IOS Software > Cisco IOS Software Release you are using > Configuration Guides.

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 both nationwide and internationally. However, some general guidelines apply:
• Determine whether the outgoing B channel calls are made in ascending or descending order. The Cisco IOS 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 following these steps:
Use the enable command and password to enter privileged EXEC mode. You are in privileged EXEC mode when the
