2. Otherwise, enter the display errors command, an d follow
corrective proced ures for any other TDM-CLK, TONE-BD, SYNC,
DS1C-B D, EXP-IN TF, SNC- BD, an d SNI- BD er rors l ogg ed, exce pt
for those in the following table.
3. If 1025 errors persist, refer to SYNC Maintenance.
h. Error Type 1281This error is an indication that the Tone-Clock circuit
pack has detec ted a loss of timing signal from the syste m synchronization
reference. The Tone-Clock circuit pack has switc hed synchronization
references.
1. Resolve any errors logged ag ainst the SYNC or STRAT-13
maintenance objects.
2. Refer to SYNC maintenance if the error is not resolved by step 1
Error Type 1282Indicates that the TN2182 tone-cloc k was synchronized
to a DS1 facility and that the reference frequ ency provided b y the DS1
drifted beyond a range that could b e tracked by t he TN2182. Therefore
the TN2182 is no longer synchronized to that DS1 referenc e. If a second
DS1 is available, the tone-clock may b e synchronized to that reference. If
no secondary DS1 reference is availab le, the tone-clock will run off of its
internal clock. This may result in slip s being reported by the tone-cloc k
and all DS1 facilities.
i. The tone-clock circuit p ack in the master port network was unable to
detect the incoming synchronization signal, b ut the other tone-clock was
able to detect the referenc es. If the aux data is 0, the prob lem is with the
signal on the primary. If the aux data i s 1, the problem is with the sig nal on
the secondary. The system should switch clocks in this situation.
1. Replace the Tone-Clock circuit pac k.
j. The indicated Tone-Clock circuit p ack has detected a loss of timing signal.
1. Enter display errors and display alarms, and follow the
associated repair p rocedures for TDM-CLK error log entries that
have on-board alarms.
2. If the 2305 errors persist:
a. Execute the test synchronization r 10 command and check
to see if new 2305 errors were reported.
