Defining ISDN Service Profile Identifiers
Some service providers assign service profile identifiers (SPIDs) to define the
services subscribed to by an ISDN device. If your service provider requires
SPIDs, your ISDN device cannot place or receive calls until it sends a valid SPID
to the service provider when initializing the connection. A SPID is usually a
seven-digit telephone number plus some optional numbers, but service providers
may use different numbering schemes. SPIDs have significance at the local access
ISDN interface only.
Currently, only DMS-100 and NI-1 switch types require SPIDs. Two SPIDs are
assigned for the DMS-100 switch type, one for each B channel. The AT&T 5ESS
switch type may support SPIDs, but Cisco recommends that you set up that ISDN
service without SPIDs.
