AT&T DS1/DMi/ISDN-PRI manual Procedure 012 Word 1 Name Database

7-38ADMINISTRATION OPTIONS AND REQUIREMENTS — SYSTEM 85

Field 8 Disables a channel’s signaling. Field encodes and their descriptions are:

–(Dash) used when ISDN is enabled.

0Used when signaling is enabled. This is the default option (not used with ISDN).

1Used when signaling is disabled. Use this with dedicated switched connection to disable signaling for a tie trunk. The signaling bit then can be used as a data bit, allowing the full 64K-bps to be used for data.

Field 9	Not applicable for ISDN-PRI.
Field 10	For outgoing AAR and TVS test calls, this field determines the encoding of the
	called party IE as assigned in procedure 107, word 1, and procedure 108, word 1. If
	the B-channel is in an ISDN dynamic trunk group, this field also determines how an
	incoming call over the trunk is processed (see the Procedure 100 Word 1 section
	earlier in this chapter).

See Appendix C, Administrative Procedure Summary, for a discussion of the called party IE and the Procedure 107 Word 1 and Procedure 108 Word 1 sections in this chapter for more information. Field encodes and their descriptions are:

0For another customer premises switch

1For a private network connection to a host computer

2For public network connections

Procedure 012 Word 1: Name Database

The name database is used by those features (such as DCS, ISDN-PRI) which provide display type information to voice terminals. Some examples of the more common display information include; calling party name, vector directory number, and trunk group name. For ISDN-PRI applications, the name database information is used to populate the display IE in the call setup and connect messages. Figure 7-16,Procedure 012 Word 1: Name Database Establish Key (System 85 R2V4), depicts the first of three related procedures.
