ATM-SYNC (ATM Synchronization)
2. Test the active Tone-Clock circuit in the master PN with test tone-clock
location long.
Check the Error Log for TDM-CLK errors, and verify that TDM Bus Clock Circuit Status
Inquiry test (#148) passes successfully.
If Test #148 fails with an Error Code 2–32, see TDM-CLK (TDM Bus Clock) to resolve
the problem. If not, continue with the following steps.
3. For Duplicated Tone-Clock circuit packs in the master PN: Switch Tone-Clock circuit
packs on the master PN with set tone-clock location.
For Simplex Tone-Clock circuit packs in the master PN: replace the primary and
secondary (if administered) DS1 Interface circuit packs.
4. Investigate any other SYNC errors.
g. Error Type 2049: the ATM Expansion Interface circuit packs have errors that affect
synchronization. Test the ATM Expansion Interface circuit pack with test board
location. This error can take up to one hour to clear.
h. 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 alarm.
