Pos Threshold - Motorola BSR 64000 Reference Manual

BSR 64000 Command Reference Guide

pos threshold

The pos threshold command sets the Bit Error Rate (BER) threshold values of
specific alarms on the POS interface. The no pos threshold command sets the rate to
the default setting.
Note: For B1-TCA, the bit interleaved parity error report is calculated by
comparing the BIP-8 code with the BIP-8 code extracted from the B1 byte of
the following frame for B1. Differences indicate that section level bit errors
have occurred.
For B2-TCA, the bit interleaved parity error report is calculated by comparing
the BIP-8/24 code with the BIP-8 code extracted from the B2 byte of the
following frame for B2. Differences indicate that line level bit errors have
occurred.
For B3-TCA, the bit interleaved parity error report is calculated by comparing
the BIP-8 code with the BIP-8 code extracted from the B3 byte of the
following frame for B3. Differences indicate that path level bit errors have
occurred.
SF-BER and SD-BER are directly related to B2 BIP-8 error counts (as is
B2-TCA). SF-BER and SD-BER feed into the APS state machine and can
lead to a protection switch if APS is configured.
B1-TCA, B2-TCA, and B3-TCA print a log message to the console if reports
for them are enabled.
To determine the BER thresholds configured on the interface, use the show
controllers pos command.
