System 85 Administration

The DS1 circuit pack uses the Common Channel Signaling mode to provide 23 trunks for data transmission and one channel for signaling. The DS1 trunk group must be assigned for AV/D using the following MAAP procedures.

1.For local and remote AUDIX setups: Assign a bearer capability of mode 0 data to the class of service for the AUDIX networking extensions (Proc 010, Word 4, Field 3 = 4).

2.Assign a trunk group and trunk type using Procedure 100, Word 1. Assign members to the trunk group using Procedure 116.

3.For remote AUDIX setups only: The trunk group used to transport the AUDIX networking call must be DS1, and the DS1 pipe must employ 24th channel signaling.

a.Enter the trunk group number (tgroup) in Field 1.

b.Make sure Touch Tone In and Touch Tone Out are set to 1 (Fields 6 and 7 = 1).

c.AVD must be set to 1 (Field 17 = 1).

4.For remote networking configurations using AAR or ARS: If the local AUDIX DCP extensions dial AAR or ARS to reach a remote AUDIX system, make sure the FRL assigned to the AUDIX networking extensions’ cos is of a sufficient value to get over the pattern and preference to allow calls from mode 0 data endpoints (Proc 309, Word 5, Field 10 = 1, or Proc 321, Word 5, Field 9 = 1).

Generic 2 Administration

This section describes the Manager II translations that must be completed on Generic 2 to implement DCP Mode 3 networking on AUDIX systems.

NOTE

DEFINITY Manager III and Manager IV are covered in their own documentation sets. Refer to the list of documents in Chapter 9 to find the appropriate manual for administering systems using Manager III or Manager IV.

1.For local and remote AUDIX setups: You should have already assigned BCCOS 6 to the AUDIX DCP extensions in Chapter 9. Refer to Chapter 9 if necessary and check Figure 9-5,Manager II Administration of a DCP Port (Proc 000, Word 3).

2.For remote AUDIX setups only: The trunk group used to transport the AUDIX networking call must be DS1, and the DS1 pipe must employ 24th channel signaling.
