Service Profile Identifier. An identifying numerical string, which is assigned by the telco to each B-Channel on a BRI line in North America, configured for multipoint service [including National ISDN-1 lines and DMS-100 lines]. The number is often arbitrary, yet for the ISDN equipment to work properly, it’s SPID configuration must match that configured in the telco switch. Recently, most telcos have standardized on a format of NPA-NXX-XXXX-0101.
SPID is the number used by your ISDN service provider to identify services on your ISDN line. A SPID informs the service provider's central office about the capabilities of each ISDN terminal (like whether the terminal accepts voice or data) on the B-channels.
Service Profile Identifier used in North America to identify the services and features the ISDN switch provides for ISDN devices. An ISDN service provider normally allocates a unique SPID (SPID1 and SPID2) for each ISDN B Channel.
Service Profile ID. These identify to the phone company what types services and features are supported for a given device. SPIDs are optional in the ISDN standard, but usually required in North America.
Service Profile Identifier. Number that some service providers use to define the services to which an ISDN device subscribes. The ISDN device uses the SPID when accessing the switch that initializes the connection to a service provider.
(Service Profile Identifier): The ISDN switch needs to have a unique identification number for each ISDN set to which it sends calls and signals. SPIDs are particular to North American BRI implementations. SPIDs allow multiple ISDN devices, such as voice and data, to share the local loop while supporting the multiple services simultaneously. SPIDs identify the services that are ordered from the carrier. For information about SPID problems, refer to Troubleshooting ISDN BRI SPIDs
Service Profile Identifier. Your ISDN service provider (telephone company) uses this number at the Central Office switch to identify services on your ISDN line. This number is derived from a telephone number. See also Central Office and ISDN.
The ISDN switch needs to have a unique identification number for each ISDN set to which it sends calls and signals.

The S/T interface is the part of an ISDN line that connects to the terminal equipment.
SPID, or "Service Profile Identifier" is a number issued by your telephone company. When a new ISDN subscriber is added, the telephone company allocates a SPID just as they would a directory number. The SPID number is used to identify your ISDN line to switch in the central office. When you're installing the system, the videoconferencing installation software prompts you for your SPID number. (You'll need to configure the SPID into your terminal before it will connect to the central office switch.)
(Service Profile IDentifier). If required, this number is supplied to you by the telephone company. Typically, if your ISDN line has only one telephone number, or you are not using ISDN service in North America, a SPID is not required. Also see ISDN
Service Profile Identifier. Used only in Basic Rate Interface (BRI) implementations of ISDN. The SPID specifies the services available on the service provider switch and defines the feature set ordered when the ISDN service is provisioned.
