ADMINISTRATION OPTIONS AND REQUIREMENTS — SYSTEM 85
7-47
Field 10
Specifies either the number (designation) of the interexchange carrier (IXC) or the
ISDN Network Service Identifier for the trunk group. The IXC/ISDN network
identifier enables the switch to provide equal access capability by populating either
the NSF IE or the Transit Network Selection IE. If sending an NSF IE and a
particular IXC vendor number is specified in this field, that entry is included in the
NSF IE. If no IXC vendor number is specified, an is created automatically in the
Transit Network Selection IE. Permitted field entries may be any number within the
range of 0 through 999.
When the trunk group is routed over private network ISDN-PRI transmission
facilities, then no IXC/ISDN network is used and the 0 option must be translated.
Each network provider (of ISDN service) will have a different IXC identifier
number. When connecting to AT&T ISDN network facilities, the required number
is 288.
