Carrier Access Access Navigator user manual Log Bert

CLI Language Reference

CLI Command List

Log BERT

Purpose: Displays BERT (bit error rate test) events, which are stored in a BERT log file that holds the most recent 200 error reports. The Access Navigator records BERT events whenever a BER test pattern is present and bit errors occur during any one-second measurement interval. The BERT log file will be erased by a power interruption, clear bert log command, reset command, or restore defaults command.

NOTE: The Access Navigator’s internal Bit Error Rate Testers (BERTs) are always monitoring the DS1 inputs. Anytime a BER test pattern is present, whether internally or externally generated, the bit errors will be recorded in the BERT log.

Security: Level 3 (monitor)
