Service Profile ID (SPID)
The SPID is a sequence of digits used to identify ISDN terminal equip-
ment to the ISDN switch. The SPID is assigned by the local phone
company when the ISDN line is installed and it usually looks similar
to the phone number. Obtain SPIDs from your telephone administra-
tor or local telephone representative.
The number of SPIDs required (0, 1, or 2) depends on how your ISDN
line is configured. For instance, a point-to-point line has no SPID.
Multipoint lines may have one or two SPIDs. The Express uses the
presence of SPID 1 to determine if the line is multipoint. If the line has
only one SPID, then it must be entered in SPID 1. Outside of North
America, the SPID format may not be used.
Example:
SPID 1 = 2 5 6 5 5 5 1 2 3 4 0 1 0 1
SPID 2 = 2 5 6 5 5 5 4 3 2 1 0 1 0 1
