BERT

The Bit Error Rate Tester (BERT) sends a data pattern and measures the bit error rate (BER) on the selected HSU port. The patterns that can be selected are off, mark (1111), space (0000), 1:1 (1010 alternating), 1:7 (0100-0000), 3:24, qrss (quasi-random signal source), prb11(pseudorandom binary sequence), prb15 and prb20.

SYNC

The Synchronization field indicates if the integrated BERT has achieved synchronization either with itself via a remote loopback or with the remote test equipment. This is an information-only field; it is not user-configurable.

BE

The Bit Error (BE) field indicates the total number of bit errors logged. This is an information-only field; it is not user-configurable.

ES

The Errored Seconds (ES) field indicates the total number of seconds in which errors were detected. This is an information-only field; it is not user-configurable.
