Reserved.
VT Signal Fail Clear. Allows the signal fail algorithm to be
forced into the normal state. This is a one shot which is
activated by a 0 to 1 transition.
VT Signal Fail Set. Allows the signal fail algorithm to be
forced into the failed state. This is a one shot which is acti-
vated by a 0 to 1 transition.
Signal Degrade Clear. Allows the signal degrade algo-
rithm to be forced into the normal state. This is a one shot
which is activated by a 0 to 1 transition.
Signal Degrade Set. Allows the signal degrade algorithm
to be forced into the failed state. This is a one shot which
is activated by a 0 to 1 transition.
Reserved.
Bit Error Rate Monitor Channel Select. Selects which
channel (1—28/21) is being monitored by the internal
BER monitor. Valid inputs are 00001—11100.
Signal Degrade Ns Set. Number of frames in a monitor-
ing 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 if a
monitoring block is bad.
Signal Degrade Ns Set. Number of frames in a monitor-
ing block for SD.
Signal Degrade B Set. Number of monitoring blocks.
