Notes:
a. The Tone-Clock circuit pack may have a clock at the edge of its specified
frequency. This can is turn cause Remote Neighbor Links (RNLs) and/or
Local Neighbor Links LNLs) to go down. When this error is alarmed, Clock
Health Inquiry Test (#46) will fail with an error code of 1.
1. Replace the Tone-Clock circuit pack identified in the error log.
b. The indicated Tone-Clock circuit pack has been made unavailable via the
busyout tone-clock PC
command. To resolve this error, execute the
release tone-clock PC
command for the alarmed circuit pack.
c. This error type indicates that the circuit pack has been removed or has
been insane for more than 11 minutes. To clear the error, reinsert or
replace the circuit pack.
d. The Tone-Clock circuit pack in the PPN is not a TN780 while a Stratum 3
synchronization is administered. Replace the Tone-Clock in the PPN with a
TN780, or change synchronization administration to Stratum 4 if a Stratum
3 clock is not being used.
e. The tone-clock has reported an out-of-lock condition. A aux value of 1
indicates this error is an out-of-lock with the primary reference. A aux
value of 2 indicates this error is an out-of-lock with the secondary
reference. It could not lock onto the frequency of that synchronization
reference. This will lead to a change in the synchronization reference if the
condition continues.

1. As a general rule, any
on board
errors against the TDM Bus Clock should be resolved before
pursuing any other errors against SPE or PNC components.
Off board
clock errors may be caused
by other board errors, and should usually be addressed once any on board errors have been
resolved.
2. Run the Short Test Sequence first. If all tests pass, run the Long Test Sequence. Refer to the
appropriate test description and follow the recommended procedures.
3. Major or Minor alarms on this MO may have been downgraded to Warning alarms based on the
values used in the set options command.
