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
