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.

Description / Recommendation
ABRT
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.

ABRT
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.

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 
2.  If the error still exists, replace the IPSI or Tone-Clock circuit pack 
reported in the error log. See 
PASS
The external synchronization timing source is valid.
