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 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).
