7.3 Bit Error Testing (BERT)
Run the BERT application to check the integrity of a T3 (DS3) circuit. It can be run with a loopback or end to end with
another test set. The indicators at the top display the current and historical state of
SIGNAL/FRAME/ALARM/ERROR/PSYNC events. The test results are reported as errors or error rates. Any events,
including Alarms and G.821 metrics, are also reported.
