Misframe Alarm Inquiry Test (#145)
Misframe Alarm indicates that framing bits observed on a DS1 Interface circuit
pack are in error. Misframe Alarm Inquiry Test queries the total number of
misframes that occurred on a DS1 Interface circuit pack since the last inquiry.
When the DS1 Interface circuit pack detects a misframe error, it will increase its
misframe counter by 1. If the counter reaches the threshold, a
MISFRAME-COUNT message is automatically sent to the switch maintenance
software. After the maintenance software receives the MISFRAME-COUNT
message, the Misframe Alarm Inquiry Test is initiated to collect the misframe
counts from the DS1 Interface circuit pack.
When the threshold of misframes is reached, if the DS1 Interface circuit pack is
supplying the system synchronization source, then a switching synchronization
source message is sent to the TDM Bus Clock. See TDM-BUS (TDM Bus)
Maintenance documentation for details. A Minor alarm against the DS1 Interface
circuit pack is raised, but all trunks of the DS1 Interface circuit pack are still in the
in-service state.
PASS No Slip alarm is detected on the DS1 Interface circuit pack.
0 NO BOARD The test could not relate the internal ID to the port (no board).
This could be due to incorrect translations, no board is
inserted, an incorrect board is inserted, or an insane board is
inserted.
1. Check to ensure that the board translations are correct.
Use the add ds1 UUCSS command to administer the
DS1 interface if it is not already administered.
2. If board was already administered correctly, check the
error log to determine if the board is hyperactive. If this is
the case, the board is shut down. Reseating the board will
re-initialize the board.
3. If the board was found to be correctly inserted in step 1,
issue the busyout board command.
4. Issue the reset board command.
5. Issue the release busy board command.
6. Issue the test board long command.
This should re-establish the link between the internal ID and
the port.
