This is not really a test, in the sense that it simply reports status held by the
system, and does not generate new information or raise alarms. If this test fails
with no error code, there is at least one Major alarm against a Tone-Clock circuit
pack. If this test fails with an error code of 1, there is at least one Minor off-board
alarm against a TDM-CLK.

ABORT
Internal System Error.
1. Retry the command at 1-minute intervals for a maximum of 5 times.
none
FAIL
This Tone-Clock circuit pack had an apparent loss of clock. One or more of
error types 2049, 2305, 3834, and 3872 will appear in the error log. Correct
the problem according to the appropriate error log entries. Once this test
fails, the only way to make it pass, and to retire the associated alarm, is to
repair the problem and to execute the set tone-clock PC override
command against the indicated Tone-Clock circuit pack.
NOTE:
If power is removed from a carrier in a duplicated system, and that
SPE has the active TONE-CLK, a MAJOR alarm is raised for the
TONE-BD. The TONE-BD will be out of service and when running
Test 46 (Clock Health Test) it will fail, indicating a loss of any of these
three clocks, SYSCLK, SYSFM, and SYSDCLK.
To restore the TONE-BD to service you must execute the set tone
spe health-override command.
1
FAIL
This Tone-Clock circuit pack is suspect of having a clock at the edge of its
specified frequency.
1. Replace the Tone-Clock circuit pack identified in the error log. Refer to
the
‘‘How to Replace a Tone-Clock Circuit Pack’’
section.
PASS
This Tone-Clock circuit pack has not reported a loss of clock.
