Signal Fail Ns Set.
Number of frames in a monitoring
block for SF.
Reserved.
Signal Fail M Set.
Threshold of the number of bad
monitoring blocks in an observation interval. If the
number of bad blocks is above this threshold, then signal
fail (SF) is set.
Signal Fail L Set.
Error threshold for determining a bad
monitoring block.
Signal Fail B Set.
Number of monitoring blocks.
Signal Fail Ns Clear.
Number of frames in a monitoring
block for SF.
Reserved.
Signal Fail M Clear.
Threshold of the number of bad
monitoring blocks in an observation interval. If the
number of bad blocks is below this threshold, then SF is
cleared.
Signal Fail L Clear.
Error threshold for determining a
bad monitoring block.
Signal Fail B Clear.
Number of monitoring blocks.

B3 Error Count.
The value of internal running counter
is transferred into this holding register coincident with
the end of a performance monitor interval.
G1 Error Count.
The value of internal running counter
is transferred into this holding register coincident with
the end of a performance monitor interval.
Reserved.
Bipolar Coding Violation Occurrence Count.
The
value of internal running counter is transferred into this
holding register coincident with the end of a
performance monitor interval.
Reserved.
Excess Zero Occurrence Count.
The value of
internal running counter is transferred into this holding
register coincident with the end of a performance
monitor interval.
