TMUX_TPOAC_C2
Transmit POAC C2 Byte Control.
When 1, causes
the incoming POAC C2 value to be inserted into the C2
byte of the selected TPOAC STS-1 if the correspond-
ing TMUX_THSC2INS (
Table 108
) control bit is desas-
serted. If the C2 is not inserted from register control or
from the transmit POAC channel, then its value
depends on SMPR_OH_DEFLT.
Transmit POAC J1 Byte Control.
Control bit, when
set to a logic 1, causes the incoming POAC J1 value to
be inserted into the J1 byte of the selected TPOAC
STS-1 if the corresponding TMUX_THSJ1INS
(
Table 108
) control bit is desasserted. If the J1 is not
inserted from register control or from the transmit
POAC channel, then its value depends on
SMPR_OH_DEFLT.

TMUX_TPOAC_OEPMON
Transmit TOAC Odd or Even Parity Monitor.
Control
bit, when set to a logic 1, forces the input TOAC parity
checker to check for odd parity; otherwise, even parity
is checked on the transmit TOAC channel.

TMUX_SDMSET[7:0]
Signal Degrade Ns Set.
Number of frames in a
monitoring block for signal degrade (SD).
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 SD is
set.
Signal Degrade L Set.
Error threshold for determining
if a monitoring block is bad.
Signal Degrade B Set.
Number of monitoring blocks.
Signal Degrade Ns Clear.
Number of frames in a
monitoring block for SD.
