Standby Reference Health Check Test (#651)
This test evaluates the quality of the external synchronization timing source for a
standby IPSI or Tone-Clock circuit pack. Every administered synchronization
timing source must be valid for this test to pass. If the Tone-Clock circuit and the
synchronization timing sources are in different port networks, the EI circuit packs
transport the timing sources to the tone-clock.

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.
0 FAIL The external synchronization timing source for side A of the Stratum-3 clock or
for the primary DS1 reference is either absent or invalid. The external
synchronization timing source for side B of the Stratum-3 clock or the
secondary DS1 reference is not yet tested.
1 FAIL The external synchronization timing source for side B of the Stratum-3 clock or
for the secondary DS1 reference is either absent or invalid.
1. Correct the synchronization source problem. See ‘‘SYNC (Port-Network
Synchronization)’’ on page 8-1509 .
2. If the error still exists, replace the IPSI or Tone-Clock circuit pack reported
in the error log. See ‘‘Replacing the IPSI or Tone-Clock Circuit Pack’’ on
page 8-1666 .
PASS The external synchronization timing source is valid.
