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.

Error
Code Test
Result Description/ Recommendation
2000 ABORT Response to the test request was not received within the allowable time
period. If Error Type 1538 is present in the Error Log, follow the
maintenance strategy recommended for this Error Type.
2100 ABORT Could not allocate the necessary system resources to run this test.
ABORT Internal system error.
1. Retry the command at 1-minute intervals a maximum of 5 times.
FAIL Test failed. Announcements recorded or played back while the clock
circuitry is not functioning properly sound distorted. The ANN-BD may be
defective or the Active Tone-Clock circuit pack (TONE-BD) may be
marginal and is causing this test to fail.
1. Reset the circuit pack with reset board PCSS and run this test again. If
the test continues to fail, go to Step 2 or 3.
!
WARNING:
Replacing the circuit pack results in loss of integrated
announcements. See
‘‘General Notes’’ near the beginning of this
Maintenance procedure.
FAIL
(cont’d.)
2. Replace the ANN-BD. Rerun the test. If the test continues to fail,
replace the Tone-Clock circuit pack.
!
WARNING:
Replacing the TONE-BD causes a COLD 2 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.
3. 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.
