3. If this is a Standard system (that is, not a High or Critical
Reliability system), replace the ANN-BD. Rerun the test. If
the test continues to fail, replace the Tone-Clock circuit
pack located in the same Port Network as the ANN-BD.
!
WARNING:
Replacing the Tone-Clock circuit pack causes a
standard system PPN to perform a COLD 2 reset or an
EPN to reset. See the “How to Replace a Tone-Clock
Circuit Pack” section in the “TONE-BD (Tone-Clock
Circuit Pack)” Maintenance documentation. Replacing
the ANN-BD results in loss of integrated
announcements. See “General Notes” near the
beginning of this Maintenance procedure.
4. If there are recurring alarms on this circuit pack caused by
this test failing, replace the ANN-BD even if the previous
steps were successful.

PASS Announcement record/playbacks should have clear sound
quality. User-reported troubles on this circuit pack should be
investigated using other circuit packs and port tests. Refer to
“ANN-PT (Announcement Port)” Maintenance documentation
for a description of the port tests.
