TMUX_SDMCLEAR[7:0]
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 if a monitoring block is bad.
Signal Degrade B Clear.
Number of monitoring blocks.

Number of monitoring blocks.
Signal Fail Ns Clear.
Number of frames in a monitoring
block for SF.
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.
