For Transport test applications, not available in Through modes.
Service Disruption
Note: Service Disruption results are only available with Transport and EtherBERT
test applications when Disruption Monitoring is enabled (refer to BERT
and Unframed BERT on page 102 or EtherBERT, FC BERT, and Unframed
BERT on page 116). When Service Disruption is disabled, the message
Service disruption monitoring disabled is displayed.
Service Disruption is the time during which there is a disruption of service
due to the detection of defects.
Disruption Time
Note: For OTL defects, at the exception of LOL, the disruption time is displayed for
the lane having the longest disruption time. See OTL-SDT on page 367 for
results per lanes.
Longest (ms): Indicates the longest measured disruption time.
Shortest (ms) indicates the shortest measured disruption time.
Last (ms) indicates the length of the last measured disruption time.
Average (ms) indicates the average duration of all measured
disruption times.
Total (ms) indicates the total duration of all measured disruption
times.
Defect, available with Transport test applications, indicates on which
layer and defect the service disruption time test is performed. For OTL
defect (parallel interface) also indicates within parenthesis the lane
number having the longest disruption time.
