PLOPTRV:
The path loss of pointer status (PLOPTRV) bit indicates the current status of the LOP-P
defect for STS-1/STM-0. When PLOPTRCFG register bits are set to 00b, PLOPTRV is
asserted when the pointer is in the LOP state and PLOPTRV is negated when the pointer is
not in the LOP state. When PLOPTRCFG register bits are set to 01b, PLOPTRV is asserted
when the pointer or any of the concatenated pointers is in the LOP state and PLOPTRV is
negated when the pointer and all the concatenation pointers are not in the LOP state. When
PLOPTRCFG register bits are set to 10b, PLOPTRV is asserted when the pointer or any of
the concatenated pointers is in the LOP state or in the AIS state and PLOPTRV is negated
when the pointer and all the concatenation pointers are not in the LOP state or in the AIS
state. When the PLOPTREND register bit is set to one, PLOPPTRV is negated when a AIS-P
defect is detected.
