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.
