Misframe Alarm Inquiry Test (#145)
Misframe Alarm indicates that framing bits observed on a UDS1 Interface circuit
pack are in error. The Misframe Alarm Inquiry Test queries the total number of
misframes that have 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 a specified threshold (i.e.- 17), 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 UDS1 Interface circuit pack.
When the threshold of misframes is reached, if the UDS1 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 UDS1
Interface circuit pack is raised, but all trunks or ports of the UDS1 Interface
circuit pack remain in the in-service state.
PASS No Slip alarm is detected on the UDS1 Interface circuit pack.

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. Ensure that the board translations are correct. Execute the add ds1 UUCSS
command to administer the UDS1 interface if it is not already administered.
2. If the board was already administered correctly, check the error log to
determine whether 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, then 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 linkage between the internal ID and the port.
