Table 88. Page 2 - Registers 128—141 (R/W)
Set parameters are used when
RHSSD
= 0, and the clear parameters are used when
RHSSD
= 1.
Note:
The thresholds written by the control system shall be one less than the desired number, except for the
SDLSet/Clear[3:0]
parameter.
Timing requirements:
When
SDSET
(
0x04
)
is set to a 1, the device sets
RHSSD
= 1, clears all remaining internal variables and counters
of the
RHSSD
algorithm, and initializes the algorithm to enable recovery declaration.
When
SDCLEAR
(
0x04
) is set to a 1, the device sets
RHSSD
= 0, clears all remaining internal variables and
counters of the
RHSSD
algorithm and initializes the algorithm to enable failure declaration.
If
SDSET
OR
SDCLEAR
is cleared to 0, do nothing.
If
SDSET
AND
SDCLEAR
are simultaneously set to 1, do nothing.
BER algorithm:
while (SDL = 0) then
disable algorithm and set
RHSSD
,
RHSSDD
= 0.

Signal Degrade Ns Set.
Number of frames in a
monitoring block for RHSSD, 0x1B.
Signal Degrade L Set.
Error
threshold for deter-
mining if a monitoring block is bad.
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 RHSSD, 0x1B is set.
Signal Degrade B Set.
Number of monitoring
blocks.
Signal Degrade Ns Clear.
Number of frames in a
monitoring block for RHSSD, 0x1B.

val. If the number of good blocks is above this
threshold, then RHSSD, 0x1B is cleared.
