1. Look at the Stratum 3 cabinet for red LEDs on circuit
cards marked "ST3." Replace the card(s).
2. Determine if the alarm still exists by issuing the test
synchronization r 4 command to clear the alarm. If
any test repetitions fail, follow the procedure for
those failures. If the problem persists after you have
performed this procedure three times, follow normal
escalation procedures.
2101 FAIL The TN780 Tone-Clock circuit pack detects loss of
signal. Refer to Note (b) of the STRAT-3 Hardware Error
Log Entries table in the STRAT-3 (Stratum 3 Clock)
Maintenance documentation for replacement
procedures.

conditions. If synchronization problems have been
reported, look for SYNC errors and refer to SYNC

recommended strategy for those errors.
