SPIDs

When you request services, you may also need the following information
about SPIDs and other service attributes:
Request multipoint, initializing terminal service; the maximum number
of terminals is two. The service provider supplies you with two SPIDs.
If you request ISDN service from an AT&T 5ESS service provider and the
switch is running custom (or non-National ISDN 1) software, the format
is:
01 + 7-digit telephone number + 1-digit suffix.
If you request a different telephone numbers for each B channel, the
suffix can be the same. A suffix of 0 is typical in this case. If you decide
to use the same telephone number for both B channels, use a different
suffix so that the two SPIDs are unique.
If you request NI-1 (National ISDN 1) service from an AT&T 5ESS service
provider, the format is:
01 + 7-digit telephone number + 1-digit suffix + 2-digit TID (terminal
identifier).
