Signal Degrade Ns Set.
Number of frames in a
monitoring block for SD.
Reserved.
Signal Degrade 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
degrade (SD) is set.
Signal Degrade L Set.
Error threshold for determining a
bad monitoring block.
Signal Degrade B Set.
Number of monitoring blocks.
Signal Degrade Ns Clear.
Number of frames in a
monitoring block for SD.
Reserved.
Signal Degrade 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 SD is
cleared.
Signal Degrade L Clear.
Error threshold for determining
a bad monitoring block.
Signal Degrade B Clear.
Number of monitoring blocks.
