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)

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
procedures specified for TDM-CLK Error Code 2305.
