Algorithm 2: PPLMV is set to logic 1 when the accepted PSL does not match, according to
Table 6, the expected PSL. PPLMV is set to logic 0 when the accepted PSL matches,
according to Table 6, the expected PSL.
PUNEQV
The path unequipped status (PUNEQV) bit indicates the current status of the UNEQ-P
defect.
PUNEQV is set to logic 1 when the received PSL indicates unequipped, according to Table
6, for 3 or 5 consecutive frames (selectable with the PSL5 register bit). An PUNEQV is set
to logic 0 when the received PSL indicates not unequipped, according to Table 6, for 3 or 5
consecutive frames.
PPDIV
The path payload defect indication status (PPDIV) bit indicates the current status of the
PPDI-P defect.
Algorithm 1: PPDIV is set to logic one when the received PSL is a defect, according to
Table 6, for 3 or 5 consecutive frames (selectable with the PSL5 register bit). PPDIV is set
to logic 0 when the received PSL is not a defect, according to Table 6, for 3 or 5 consecutive
frames.
Algorithm 2: PPDIV is set to logic 1 when the accepted PSL is a defect, according to Table
6. PPDI is set to logic 0 when the accepted PSL is not a defect, according to Table 6.
PRDIV
The path remote defect indication status (PRDIV) bit indicates the current status of the
RDI-P defect. PRDIV is set to logic 1 when bit 5 of the G1 byte is set high for five or ten
consecutive frames (selectable with the PRDI10 register bit). PRDIV is set to logic 0 when
bit 5 of the G1 byte is set low for five or ten consecutive frames.
PERDIV
The path enhanced remote defect indication status (PERDIV) bit indicates the current status
of the ERDI-P defect. PERDIV is set to logic 1 when the same 010, 100, 101, 110 or 111
pattern is detected in bits 5, 6 and 7 of the G1 byte for five or ten consecutive frames
(selectable with the PRDI10 register bit). PERDIV is set to logic 0 when the same 000, 001
or 011 pattern is detected in bits 5, 6 and 7 of the G1 byte for five or ten consecutive frames.
