Maintenance documentation. Before switching back to the new
TN780 Tone-Clock circuit pack, use the test tone-clock PC long
command to check that the Tone-Clock is receiving a signal from
the Stratum 3 clock. The notation "PC" denotes a port network
number and carrier. If all tests pass, switch to the new Tone-Clock
circuit pack via the set tone-clock PC override command. If Test
#651 fails, then the original TN780 Tone-Clock should be
reinserted, and the cable between the Stratum 3 clock and the
TN780 Tone-Clock circuit pack should be replaced. If Test #651
continues to fail, then escalate the problem.
