Notes:
a. The Tone-Clock circuit pack may have a clock at the edge of its specified
frequency. This can cause Expansion Interface circuit packs and SNI
circuit packs to go out-of-frame or report no-neighbor conditions. This can
is turn cause EPNs, Expansion Archangel Links (EALs), 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. See
How to Replace the Tone-Clock Circuit Pack
in the TONE-BD
section.
b. The indicated Tone-Clock circuit pack has been made unavailable via the
busyout tone-clock UUC command. It only applies to systems which
have the High or Critical Reliability Option administered, because only a
standby Tone-Clock circuit pack may be made busy by that command. To
resolve this error, execute the release tone-clock UUC 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.
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.
