ADMINISTRATIVE PROCEDURE SUMMARY
Field 15
BC (System 85 R2V4 Only). For ISDN-PRI this field comes into play on interworked
tandem calls through the switch where the calling trunk is non-ISDN-PRI and the
called trunk is ISDN-PRI. Here, the BC of the non-ISDN trunk is used to define a BC
that is used in the outgoing setup message over the ISDN-PRI trunk. See the B C
section for encodings of the BC IE.

The BC is also used to determine which ARS/AAR route to select. This is discussed
in the Procedure 309 Word 5 and Procedure 321 Word 5 sections later in this appendix.

PROCEDURE 107 WORD 1 (System 85 R2V4 & Generic 2)
This procedure is used to assign terminating test line telephone number digits to ISDN-PRI trunk
groups. When placing a trunk verification by station (TVS) or trunk verification by customer (TVC)
test call, these digits are used to build the called party number IE in the setup message for the trunk
group under test. If digits are not translated for a trunk group and a TVC/TVS call is made for a
channel in this trunk group, the resulting called party number IE will not contain address digits.

Called-Party Number IE (System 85 R2V4 & Generic 2)
The following rules are used in building this IE. These rules apply to all types of calls made out of
the switch and not just test calls. The rules are checked by the system in the order shown below. The
first true rule encountered results in the IE being built as shown for that rule.
