Clock Match Inquiry Test (#212)
This test is supported to determine the state of the clock generation circuitry on
the Announcement circuit pack. This circuitry is used for controlling various pieces
of the hardware, like the 140AY device. It is also used to synchronize the
Announcement circuit pack with the clock that is on the backplane.
FAIL Test failed. Announcement playbacks should sound corrupted.
1. Reset the circuit pack via the reset board PCSS
command and then run this test again. If the test continues
to fail, replace the circuit pack (see Warning).
2. If there are recurring alarms on this circuit pack caused by
this test failing, replace the circuit pack even if Step 1
works (see Warning).
!
WARNING:
Replacing the circuit pack results in loss of integrated
announcements. See “General Notes” near the
beginning of this Maintenance procedure.
PASS The SP can properly process record/playback requests.
User-reported troubles on this circuit pack should be
investigated using other circuit pack and port tests. Refer to
“ANN-PT (Announcement Port)” Maintenance documentation
for a description of the port tests.
