Standby Reference Health Check Test (#651)
This test evaluates the quality of the external synchronization timing source for
the Standby Tone-Clock circuit pack.

Result Description/ Recommendation
ABORT This test may already be running due to a tone-clock installation, scheduled
maintenance, alarm activity, or a technician-demand test from another
terminal. This abort can also occur due to an internal system error.
1. Try the command again at 1-minute intervals up to five times.
1184 ABORT This test requires an external synchronization source to be administered
(DS1 primary, DS1 primary and secondary, or Stratum 3 Clock).
1. Administer the external synchronization source and retry the test.
2500 ABORT Internal system error
1. Try the command again at 1-minute intervals up to 5 times.
0FAILIf the Tone-Clock circuit pack is in the PPN, the external synchronization
timing source for side A of the Stratum 3 clock, or for the Primary DS1
reference is either absent or invalid. If the Tone-Clock circuit pack is in
an EPN, the synchronization reference from the active EI circuit pack is
either absent or invalid.
1FAILIf the Tone-Clock circuit pack is in the PPN, both external
synchronization timing sources are either absent or invalid. If the
Tone-Clock circuit pack is in an EPN, the synchronization references
from both EI circuit packs are either absent or invalid.
1. Correct the synchronization source problem. Refer to the
Synchronization (SYNC) maintenance section of this manual.
2. If the error still exists, replace the Tone-Clock circuit pack reported in
the error log.
PASS The external synchronization timing source is valid.
