ADX8D-PT (AUDIX Digital Port)
The ADX8D-PT MO represents a port on a TN566/TN2169 EMBEDDED AUDIX
circuit pack (also called DEFINITY AUDIX) operating in DP (digital-port) mode.
The maintenance strategy for ports on the TN566 operating in control-link mode is
described in ADX16A-PT.
The tests described in this section apply only to switch-side maintenance that
tests a circuit pack’s components related to the TDM-bus interface. The AUDIX
system has an extensive maintenance strategy that is described in EMBEDDED
AUDIX System Maintenance, 585-300-110.
AUDIX resides on a combined pair of circuit packs: the TN566 MFB (multifunction
board) and the TN2169 ALB (alarm board). Because of its size, this combination
occupies 5 slots, but only 1 slot is functional as far as the switch is concerned.
The other 4 slots are seen by the switch as “AUDIX-reserved” slots (or
ADXDP-RS/ADX8D-RS).
In DP mode the TN566 pack supports up to 8 voice ports, each with a primary and
a secondary information channel. Ports are administered in increments of two.
When a call to a station with an AUDIX login is not answered, AUDIX answers the
call using one of the available voice ports.
Unlike other AUDIX systems, EMBEDDED AUDIX is not an adjunct.
!
CAUTION:
Never do any of the following without first shutting down AUDIX. Follow
instructions on the TN566/TN2169 faceplate:
■ Remove EMBEDDED AUDIX circuit packs
■ Cycle power to a carrier containing EMBEDDED AUDIX circuit packs
