Defining ISDN Service Profile Identifiers
An ISDN service provider, usually a telephone company, can offer a variety of
services. Many providers use service profile identifiers (SPIDs) to identify the
device that is using the ISDN service, similar to the way that the telephone
company uses a telephone number to identify your standard telephone service. If
you use such a service provider, the provider assigns your ISDN device one or
more SPIDs when you first subscribe to the service. Providers use different
numbering schemes, but a SPID is usually a seven-digit telephone number, plus
some optional numbers.
The provider also assigns your device one or two local directory numbers (LDNs),
which function as the router telephone number. The LDN is the number that a
remote router dials to make a call to your router.
