Signal Fail M Set. Threshold of the number of
bad monitoring blocks in an observation
interval. If the number of bad blocks is below
this threshold, then RHSSD is cleared.
Reserved. These bits must be written to their
reset default value (0x0).
Signal Fail L Set. Error threshold for
determining if a monitoring block is bad.
Signal Fail Ns Set. Number of frames in a
monitoring block for RHSSD.
Reserved. This bit must be written to its reset
default value (0).
Signal Fail B Set. Number of monitoring
blocks.
Signal Fail Ns Set. Number of frames in a
monitoring block for RHSSD.
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 RHSSD is cleared.
Reserved. These bits must be written to their
reset default value (0x0).
Signal Fail L Clear. Error threshold for
determining if a monitoring block is bad.
Signal Fail Ns Clear. Number of frames in a
monitoring block for RHSSD.
Reserved. This bit must be written to its reset
default value (0).
Signal Fail B Clear. Number of monitoring
blocks.
Signal Fail Ns Clear. Number of frames in a
monitoring block for RHSSD.
