Never do any of the following without first shutting down AUDIX. Follow the 
instructions on the TN566/TN2169 faceplate:

The ADX16D-P MO represents a port on a TN566/TN2169 EMBEDDED AUDIX circuit pack 
operating in digital-port (DP) 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 DEFINITY AUDIX System Release 3.2.4 
Maintenance, 585-300-110.
AUDIX resides on a combined pair of circuit packs: the TN566 Multifunction board (MFB) and 
the TN2169 Alarm board (ALB). Because of its size this combination occupies 5 slots, but the 
system sees only 1 slot as functional. The other 4 slots are seen by the switch as 
“AUDIX-reserved” slots (or ADX16-RES/ADX16D-RS).
In 16-port DP mode, the TN566 pack supports up to 16 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.
