1. If the Tone-Clock circuit pack reporting the problem is a master clock, then
the system synchronization reference is providing a bad timing source.
Refer to SYNC (Synchronization) or STRAT-3 (Stratum 3 Clock)
Maintenance documentation to change the system synchronization
reference.

2. If the Tone-Clock circuit pack is a slave clock, then the EI to which it is
listening is providing a bad timing source. Follow the diagnostic
