TPAISPTRCFG[1:0]
The transmit path AIS pointer configuration (TPAISPTRCFG[1:0]) bits define the transmit
AIS-P defect. When TPAISPTRCFG[1:0] is set to 00b, a transmit AIS-P defect is declared
when the SHPI pointer is in the AIS state and an AIS-P defect is removed when the pointer
is not in the AIS state. When TPAISPTRCFG[1:0] is set to 01b, a transmit AIS-P defect is
declared when the SHPI pointer or any of the concatenated SHPI pointers is in the AIS state
and an AIS-P defect is removed when the pointer and all the concatenation pointers are not
in the AIS state. When TPAISPTRCFG[1:0] is set to 10b, a transmit AIS-P defect is
declared when the pointer and all the SHPI concatenated pointers are in the AIS state and an
AIS-P defect is removed when the pointer or any of the concatenation pointers is not in the
AIS state.
TPLOPTREND
The transmit path loss of pointer removal (TPLOPTREND) bit controls the removal of a
transmit LOP-P defect when a transmit AIS-P defect is declared. When TPLOPTREND is
set to logic 1, a transmit LOP-P defect is terminated when a transmit AIS-P defect is
declared. When TPLOPTREND is set to logic 0, a transmit LOP-P defect is not terminated
when a transmit AIS-P defect is declared.
