BERT and Unframed BERT - CPRI/OBSAI
Service Disruption
The presence of any defect, listed in the following table, triggers the service
disruption measurement; this includes any defect above in the hierarchy. If
a measurement exceeds the Test Period of 5 minutes, a service disruption
equal to the Test Period is recorded. The service disruption measurements
are cleared when changing the criteria. Only available with framed test.
No Defect Time (ms) allows selecting the period without any defects
before stopping SDT measurement: 0.005 ms to 2000 ms (default is
300 ms).
Disruption Monitoring check box when selected (disabled by
default) enables the disruption time measurements. However, the
measurement will only start if the test is already started, or when the
test will be started. Clearing the Disruption Monitoring check box or
stopping the test, stops the measurement without clearing the results.
Starting the test while the Disruption Monitoring check box is
selected resets the results.
