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 number 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).
