ADX8D-PT (AUDIX Digital Port)

ADX8D-PT (AUDIX Digital Port)
S8700 | 8710 / S8500
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.
