Board Type Check Test (#574)
This test verifies that a Tone-Clock circuit pack administered with a Stratum 3
Clock source has code TN780
Standby Reference Health Check Test (#651)
This test evaluates the quality of the external synchronization timing source for a
standby Tone-Clock circuit pack. All administered synchronization timing sources
must be valid for this test to pass. If the tone-clock circuit pack 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
2012 ABORT Internal system error
1. Retry the command at 1-minute intervals a maximum of 5 times.
ANY FAIL Stratum 3 Clock Synchronization is administered for the carrier in which this
Tone-Clock circuit pack resides, but the Tone-Clock does not have code
TN780.
1. If the Stratum 3 Clock option is incorrectly administered, remove it.
2. Otherwise, replace the circuit pack. See
How to Replace the Tone-Clock
Circuit Pack
in the TONE-BD section.
PASS The proper (TN780) Tone-Clock circuit pack code is present for Stratum 3
Clock synchronization.

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.
