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.

Procedure 321 Word 5: AAR and ISDN Trunk — Network Characteristics

This procedure is used to translate ISDN trunk groups in the AAR plan. Figure 7-22, Procedure 321 Word 5: AAR and Transit Network Identifiers (System 85 R2V4), depicts this procedure.
