AUDIX Software
An AUDIX network can consist of a mixture of R1V3, R1V4, R1V5, R1V6, and R1V7 systems. If desired,
you may upgrade your AUDIX-L to R1V5 or upgrade your AUDIX one- or two-cabinet system to the latest
software version. See the System Description manual (585-305-201) for ordering codes.
NOTE
If the network contains R1V3 or R1V4 systems, the Sending Restrictions feature cannot be
used.
ACC/ACCE
The AUDIX Communications Controller (ACC) or AUDIX Communications Controller Enhanced (ACCE)
is the circuit pack that provides the interconnections for AUDIX networking. It must be installed in slot 03
of a one- or two-cabinet AUDIX system and in slot 16 of an AUDIX Large Data Base Processor (DBP)
carrier (J58888K).
This section describes the ACC or ACCE circuit packs currently in existence. All new AUDIX systems
ordered with networking are shipped with the latest circuit pack available, currently the TN539B AUDIX
Communications Controller Enhanced (ACCE). However, a new AUDIX system can be added to an
existing network where the earlier TN366, TN366B, or TN539 circuit packs are used.
TN366 ACC
This circuit pack provides four DCP channels. It must be a TN366 vintage 5 or later. This circuit pack is
no longer orderable, but if the customer has an older vintage and wishes to upgrade, this circuit pack is
available through QPPCN 330DR (comcode 103279840). It will work with R1V3 and later software.
TN366B ACC
This circuit pack provides four DCP channels. It will work with R1V3 or later software. This circuit pack
is no longer orderable (comcode 106186588).
The TN366B is a TN366 that has been enhanced for the following reasons:
• The TN366B will work with modem pools that use 7400A DSUs; the original TN366 will not.
• The TN366B will work with the MERLIN II Communications System which is used as a DCP interface
for non-DCP switches; the TN366 will not.
• When a Generic 2 universal module serves as the host switch, the TN366B allows access to all four
DCP channels; the TN366 does not.
