ISDN BRI Line Configuration Requirements

Before using a Cisco 1721 router with an ISDN BRI WIC installed, you must

order a correctly configured ISDN BRI line from your local telecommunications

service provider.

This process varies dramatically from provider to provider, both nationally and

internationally. However, the following are some general guidelines:

• Ask for two channels to be called by one number.

• Ask for delivery of calling-line identification. This is also known as caller ID

or automatic number identification (ANI).
