TMUX_RLAISMON_AISINH
Receive Line AIS Monitor AIS Inhibit.
Control bit,
when set to a logic 1, inhibits the associated alarm
from causing AIS generation; otherwise, the associ-
ated failure causes AIS generation on all STS-1/AU-3
outputs as well as the assertion of AUTO_AIS out-
puts.
TMUX_RLOF_AISINH
Receive Loss-of-Frame AIS Inhibit.
Control bit,
when set to a logic 1, inhibits the associated alarm
from causing AIS generation; otherwise, the associ-
ated failure causes AIS generation on all STS-1/AU-3
outputs as well as the assertion of AUTO_AIS out-
puts.
TMUX_ROOF_AISINH
Receive High-speed Out-of-Frame AIS Inhibit.
Control bit, when set to a logic 1, inhibits the associ-
ated alarm from causing AIS generation; otherwise,
the associated failure causes AIS generation on all
STS-1/AU-3 outputs as well as the assertion of
AUTO_AIS outputs.
TMUX_RHSLOS_AISINH
Receive High-speed Loss-of-Signal AIS Inhibit.
Control bit, when set to a logic 1, inhibits the associ-
ated alarm from causing AIS generation; otherwise,
the associated failure causes AIS generation on all
STS-1/AU-3 outputs as well as the assertion of
AUTO_AIS outputs.
TMUX_RILOC_AISINH
Receive Input Loss-of-Clock AIS Inhibit.
Control
bit, when set to a logic 1, inhibits the associated alarm
from causing the assertion of the AUTO_AIS outputs;
otherwise, the associated failure causes assertion of
all AUTO_AIS output signals.

TMUX_FORCEC2DEF[2:0]
Force TMUX_RPLMP Defects.
These bits (one for
each STS-1 in an STS-3) will force TMUX_RPLMP
defects on certain conditions as shown in
Table 524
(STS Signal Label Defect Conditions).
TMUX_LOSDETCNT[10:0]
Loss-of-Signal Detection Count.
Control bits are the
number of consecutive all-0s/1s pattern detected to
declare LOS state in the unscrambled STS-3/STM-1
(AU-4) input frame. A value of 0x02D equals 2.3 μs
while a value of 0x798 equals 100 μs.
