TMUX_RINCE2
Receive Pointer Increment Event.
This event bit indicates
that a valid incoming pointer increment indication was
received on port 2. Only port 1 information is valid in AU-4
mode and in STS-1 mode. The mask bit is TMUX_RINCM2
(
Table 87
). However, increment and decrement event indica-
tion should be ignored during loss-of-pointer (LOP) condi-
tion.
Receive Path AIS Delta.
This delta bit indicates a change in
state of the TMUX_RPAIS2 (
Table 92
) state bit, which desig-
nates that the port 2 pointer interpreter is in the alarm indica-
tion signal state. Only port 1 information is valid in AU-4
mode and in STS-1 mode. The mask bit is TMUX_RPAISM2
(
Table 87
).
Receive Loss of Pointer Delta.
This delta bit indicates a
change in state of the TMUX_RLOP2 (
Table 92
) state bit,
which designates that the port 2 pointer interpreter is in the
loss of pointer state. Only port 1 information is valid in AU-4
mode. The mask bit is TMUX_RLOPM2 (
Table 87
).
Receive Path Signal Fail BER Algorithm Delta.
This delta
bit indicates a change of state for the signal fail BER algo-
rithm state bit TMUX_RSFB32 (
Table 92
) at the path level for
port 3. Only port 1 information is valid in AU-4 mode and in
STS-1 mode. The mask bit is TMUX_RSFB3M3 (
Table 87
).
Receive Path Signal Degrade BER Algorithm Delta.
This
delta bit indicates a change of state for the signal fail BER
algorithm state bit TMUX_RSDB32 (
Table 92
) at the path
level for port 3. Only port 1 information is valid in AU-4 mode
and in STS-1 mode. The mask bit is TMUX_RSDB3M3
(
Table 87
).
Receive Path Unequipped Event.
This event bit indicates
that the current value of the received C2 (signal label) byte,
TMUX_C2MON3[7:0] (
Table 104
), has a value 0x00, indicat-
ing unequipped payload for port 3. Only port 1 information is
valid in AU-4 mode and in STS-1 mode. The mask bit is
TMUX_RUNEQPM3 (
Table 87
).
Receive Path Payload Label Mismatch Event.
This event
bit indicates that the current value of the received C2 (signal
label) byte, TMUX_C2MON3[7:0], differs from the expected
C2 value, TMUX_C2EXP3[7:0] (
Table 100
) for port 3. Only
port 1 information is valid in AU-4 mode and in STS-1 mode.
The mask bit is TMUX_RPLMPM3 (
Table 87
).
