PPLUV:
The path payload label unstable status (PPLUV) bit indicates the current status of the PLU-P
defect.
Algorithm 1: PPLUV is set to logic 0.
Algorithm 2: PPLUV is set to logic 1 when a total of 5 received PSL differs from the previously
received PSL without any persistent PSL in between. PPLUV is set to logic 0
when a persistent PSL is found. A persistent PSL is found when the same PSL is
received for 3 or 5 consecutive frames.
PPLMV:
The path payload label mismatch status (PPLMV) bit indicates the current status of the PLM-
P defect.
Algorithm 1: PPLMV is set to logic 1 when the received PSL does not match, according to
Table 1, the expected PSL for 3 or 5 consecutive frames (selectable with the
PSL5 register bit). PPLMV is set to logic 0 when the received PSL matches,
according to Table 1, the expected PSL for 3 or 5 consecutive frames.
