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; 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 may 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 spid-number [ldn]
Router(config-if)# isdn spid2 spid-number [ldn]
Although the LDN is an optional parameter in the command, you may need to enter it so the router
Note
can answer calls made to the second directory number.
