The path AIS pointer configuration (PAISPTRCFG[1:0]) bits define the AIS-P defect. When
PAISPTRCFG[1:0] is set to 00b, an AIS-P defect is declared when the pointer is in the AIS
state and an AIS-P defect is removed when the pointer is not in the AIS state. When
PAISPTRCFG[1:0] is set to 01b, an AIS-P defect is declared when the pointer or any of the
concatenated 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 PAISPTRCFG[1:0] is set to 10b,
an AIS-P defect is declared when the pointer and all the 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.
The path loss of pointer removal (PLOPTREND) bit controls the removal of a LOP-P defect
when an AIS-P defect is declared. When PLOPTREND is set to logic 1, a LOP-P defect is
terminated when an AIS-P defect is declared. When PLOPTREND is set to logic 0, a LOP-P
defect is not terminated when an AIS-P defect is declared.
The path enhance remote defect indication (PERDI22) bit selects the path ERDI persistence.
When PERDI22 is set to logic 1, a new path ERDI indication is transmitted by the THPP for
at least 22 frames. When PERDI22 is set to logic 0, a new path ERDI indication is
transmitted by the THPP for at least 12 frames.
The path remote defect indication enable (PRDIEN) bit selects between the 1 bit RDI code
and the 3 bits ERDI code. When PRDIEN is set to logic 1, the 1 bit RDI code is transmitted
by the THPP. When PRDIEN is set to logic 0, the 3 bit ERDI code is transmitted by the
THPP.
