Chapter 3: ISDN Line Ordering and Configuration

Service Profile Identifiers

SPIDs, also assigned by the ISDN service provider, identify the services and features that the telephone company switch provides to the ISDN device. Commonly implemented in the U.S. and Canada, the SPID is often derived from the directory number, combined in a series with other digits. SPIDs are not generally implemented outside the U.S. and Canada.

Telephone Switch Parameters

Once you have contacted your service provider and learned the type of ISDN switch being used, refer to Table 1, Table 2, and Table 3. You must supply the appropriate provisioning information to the service provider to ensure proper configuration of the ISDN line.

NOTE

National ISDN 1 (NI-1) is a specification released by Bellcore outlining a basic set of ISDN services used for standardization by equipment vendors.
