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.
