Signal Fail Ns Set [18:3]. Number of frames in
a monitoring block for SF.

default value (0).

val. If the number of bad blocks is above this
threshold, then SF (signal fail) is set. (See Table
86, page 187, for register settings in terms of
corresponding BER.)
Signal Fail L Set. Error threshold for determin-
ing if a monitoring block is bad. (See Table 86,

settings in terms of corresponding BER.)
Signal Fail Ns Clear [18:3]. Number of frames
in a monitoring block for SF.
Reserved. This bit must be written to its reset
default value (0).
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 (signal fail) is cleared.
Signal Fail L Clear. Error threshold for deter-
mining if a monitoring block is bad.
Signal Fail Ns Clear [2:0]. Number of frames
in a monitoring block for SF.
Signal Fail B Clear. Number of monitoring
blocks.
