Defining ISDN Service Profile Identifiers

Some service providers assign service profile identifiers (SPIDs) to define the services to which an ISDN
device subscribes. 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 might use
different numbering schemes. SPIDs have significance at the local access ISDN interface only; remote
routers are never sent the SPID.
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 might support SPIDs, but
Cisco recommends that you set up that ISDN service without SPIDs.
If your service provider assigns you SPIDs, you must define these SPIDs on the router. To define SPIDs
and the local directory number (LDN) on the router for both ISDN BRI B channels, use the following
isdn spid commands:
Router (config-if)# isdn spid1
Router (config-if)# isdn spid2
Note Although the LDN is an optional parameter in the command, you might need to enter it so the router
can answer calls made to the second directory number.
For further information on configuring ISDN, see the chapters "Configuring ISDN" and "Configuring
DDR" in the Wide-Area Networking Configuration Guide publication, for your Cisco IOS software
release.
