PLOPTRV[1:12]
The path loss of pointer status (PLOPTRV[1:12]) bits indicate the current status of the LOP-
P defect STS-1/STM-0 paths #1 to #12. These bits reflect the assertion of the LOP condition
for a specific path on the RALM output.
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 an AIS-P defect is detected.
