Misframe Alarm Inquiry Test (#145)
A 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 UDS1 Interface circuit pack since the last inquiry.
When the UDS1 Interface circuit pack detects a misframe error, it increments its misframe 
counter by one. 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.
If the UDS1 Interface circuit pack is supplying the system synchronization source, when the 
threshold of misframes is reached, then a switching synchronization source message is sent to 
the TDM bus Clock. See 
on page 2237 for details. A Minor alarm against 
the UDS1 Interface circuit pack is raised, but every trunk or port of the UDS1 Interface circuit 
pack remains in the in-service state.
