Item Definition
Timer Number of days, hours, minutes, and seconds since the last reset
Composite LOS Errors Number of optical loss of signal errors
Electrical LOS Errors Number of electrical loss of signal errors
SQL Rx Errors Number of received squelch occurrences
BERT Sync Status Reports loss if the BERT out of sync error rate exceeds 10 E-9 or
OK if signal is good
BERT Sync Count Number of good to faulty patterns
BERT Bit Errors Number of bits with errors in the received pattern
BERT BER (1E-9) Number of bit errors during this BERT up time
BERT Up Time How long BERT is available and running
The Bit Error Rate Test (BERT) sends a continuous sequence to check for bit errors while the optical
signal remains in sync.
