ATM-SYNC (ATM Synchronization)

4. Investigate any other SYNC errors.

f. Error Type 2049: the ATM Expansion Interface circuit packs have errors

that affect synchronization. Test the ATM Expansion Interface circuit pack

with the test board UUCSS command.

This error is cleared by a "leaky bucket" strategy and takes up to one hour

to clear (leak away) the error counter once it is cleared.

g. Error Types 1, 257, and 513: noise on the DS1 line can cause transient

alarms on synchronization. Therefore, when a synchronization problem

occurs on Error Types 1, 257, or 513, a WARNING alarm is first raised for

15 to 20 minutes before the alarm is upgraded to a MINOR or MAJOR

Order of Investigation

Test Synchronization test (#417)

D = Destructive, ND = Non-destructive

Test Synchronization Test (#417)

This test updates all the Synchronization Maintenance component circuit packs

with the correct information regarding their role in providing synchronization for

the system. All the Tone-Clock, ATM Expansion Interface, DS1 Interface, and

UDS1 Interface circuit packs in the system are updated through this test. This test

either passes or aborts.

For Simplex Tone-Clock circuit packs in the master port network:

replace the primary and secondary (if administered) DS1 Interface

circuit packs.
