Performance Monitor Bit Error Tests
Background
This procedure will verify that performance monitoring reports show proper optical
power and zero B2 parity error rates.
Procedures
Perform the steps in the following table to complete the Monitor Bit Error Tests:
NOTE:
If at any step the requirements are not met, resolve the problem using
procedures in the 365-575-387 WaveStar OLS 40G User/Service Manual
before proceeding.
Step Action
1 Execute the PERFORMANCE.Retreive-Performance Monitoring-
Supervisory command and fill in the AID with SUPR-ALL.
Requirement: The report should not indicate OUT OF RANGE for the
last fifteen minutes.
NOTE:
The previous requirement assumes the ring has been established
for at least 15 minutes. If the ring is newly established, the 24 hour
report may indicate Out of Range.
2 Execute the PERFORMANCE.Retreive-Performance Monitoring-Optical
Line command and fill in the AID with OLINE ALL.
Requirement: The report should indicate 0 B2 errors in the last fifteen
minutes.
NOTE:
If the ring is newly established there will be a “?” in the 24 hour
report. A “0?” indicates that the data is not valid, wait for another
fifteen minute interval to elapse. Errors in the last fifteen minutes
could be due to faulty OAs, TLMs, or dirty fiber connections. There
are other causes as well. Remember that PM data is given for
incoming signals only, but the problem could be at the transmitting
end or the receiving end.
