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.

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.
