Test Setup - Test Configurator, Timer, and System
186 88000 Series
EtherBERT, FC BERT, BERT (eCPRI, CPRI/OBSAI, and FlexE), and Unframed BERT
Service Disruption
Note: Not available for FC BERT, FlexE BERT, and when the No Pattern Analysis
(Live) check box is selected.
No Traffic Time (ms) represents the time between two Ethernet
Frames that is acceptable without raising an alarm including a Service
Disruption event: 0.005 ms to 1000 ms in step of 0.005 ms (default is
50 ms). Only available with EtherBERT and eCPRI BERT.
No Defect Time (ms) represents the period without any defects before
stopping SDT measurement: 0.005 ms to 2000 ms (default is 300 ms).
Only available with CPRI/OBSAI.
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.
Note: Clearing the Disruption Monitoring check box will stop the measurement
without clearing the results. The disruption monitoring is automatically
stopped without clearing results when the test is stopped. However, starting
the test again while the Disruption Monitoring check box is selected will
reset the results before restarting.
Pass/Fail Verdict allows enabling and configuring the SDT Threshold.
SDT Threshold allows configuring the amount of time with no traffic
that is accepted before failing the test: 0.005 to 299999.995 ms in step
of 0.005 ms (default is 50 ms) for 10M to 10G; 0.001 to 299999.999 ms in
step of 0.001 ms (default is 50 ms) for 25G to 400G. For EtherBERT and
eCPRI BERT, the threshold value cannot be less than the No Traffic
Time value.
