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.

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. Verify that the board’s translations are correct. Use add ds1
location to administer the DS1 interface if it is not already
administered.
2. If board was already administered correctly, check the error log to
determine whether the board is hyperactive. If so, the board was shut
down. Reseating the board will re-initialize it.
3. If the board was found to be correctly inserted in step 1, enter
busyout board
4. Enter reset board
5. Enter release board
6. Enter test board long
This should re-establish the link between the internal ID and the port.
