00
0x4004B 15:14 TMUX_RPOAC_SEL[1:0]
Receive POAC STS-1 Port Selection.
Designates which
STS-1 inserts its path overhead bytes onto the receive
POAC channel. Values of 00 or 01 designate STS-1 #1, 10
designates STS-1 #2, 11 designates STS-1 #3.
13
TMUX_RPOAC_OEPINS
Receive POAC Odd or Even Parity Insert.
When 1,
forces receive the output POAC parity bit to be even; other-
wise, the parity is odd.

Reserved.
9:8
TMUX_TPOAC_SEL[1:0]
Transmit POAC STS-1 Port Selection.
Designates which
STS-1 obtains path overhead bytes from the transmit
POAC channel. Values of 00 or 01 designate STS-1 #1, 10
designates STS-1 #2, 11 designates STS-1 #3.

6
TMUX_TPOAC_N1
Transmit POAC N1 Byte Control.
When 1, causes the
incoming POAC N1 value to be inserted into the N1 byte of
the selected TPOAC STS-1 if the corresponding
TMUX_THSN1INS (
Table 108
) control bit is desasserted.
If the N1 is not inserted from register control or from the
transmit POAC channel, then its value depends on
SMPR_OH_DEFLT (
Table 67
).
5
TMUX_TPOAC_K3
Transmit POAC K3 Byte Control.
When 1, causes the
incoming POAC K3 value to be inserted into the K3 byte of
the selected TPOAC STS-1 if the corresponding
TMUX_THSK3INS (
Table 108
) control bit is desasserted.
If the K3 is not inserted from register control or from the
transmit POAC channel, then its value depends on
SMPR_OH_DEFLT.
4
TMUX_TPOAC_F3
Transmit POAC F3 Byte Control.
When 1, causes the
incoming POAC F3 value to be inserted into the F3 byte of
the selected TPOAC STS-1 if the corresponding
TMUX_THSF3INS (
Table 108
) control bit is desasserted. If
the F3 is not inserted from register control or from the
transmit POAC channel, then its value depends on
SMPR_OH_DEFLT.
3
TMUX_TPOAC_F2
Transmit POAC F2 Byte Control.
When 1, causes the
incoming POAC F2 value to be inserted into the F2 byte of
the selected TPOAC STS-1 if the corresponding
TMUX_THSF2INS (
Table 108
) control bit is desasserted. If
the F2 is not inserted from register control or from the
transmit POAC channel, then its value depends on
SMPR_OH_DEFLT (
Table 67
).
