TONE-BD (Tone-Clock Circuit Pack)
Clock Health Inquiry Test (#46)
This inquiry reads special data stored in memory to determine if this IPSI circuit
pack had a loss of any of three clock types:
SYSCLK
SYSFM
SYSDCLK
If this data indicates this IPSI circuit pack had a loss of any of these clocks, the
inquiry reports FAIL. In addition, if TDM-CLK error 1 is at threshold, this test will
FAIL. TDM-CLK error 1 indicates a suspect clock is at the edge of its specified
frequency. If the circuit pack did not have a loss of clock or TDM-CLK error 1 at
threshold, the inquiry reports PASS.
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 an IPSI 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.

Description / Recommendation
Internal system error.
Retry the command at 11-minute intervals up to 5 times.
This IPSI circuit pack had an apparent loss of clock. One or more
of error types 2049, 2305, 3834, 3857, 3858 and 3872 will appear
in the error log. Correct the problem according to the appropriate
error log entries.
Once this test fails for an IPSI circuit pack's Tone-Clock circuit, the
only way to make it pass (and to retire the associated alarm) is to
repair the problem, to execute the busy ipsi command, and then
issue the release ipsi command against the indicated IPSI circuit
pack.
This IPSI circuit pack is suspected of having a clock at the edge of
its specified frequency.
Replace the IPSI circuit pack identified in the error log. See
''Replacing the IPSI Circuit Pack'' on page
This IPSI circuit pack has not reported a loss of clock.
