The RHPP also monitors the path signal label byte (C2) to detect path payload label mismatch
(PLM-P) defect. PLM-P is declared when the accepted PSL does not match the expected PSL
according to Table 6. PLM-P is removed when the accepted PSL match the expected PSL
according to Table 6. The accepted PSL is the same PSL value received for three or five
consecutive frames (selectable by the PSL5 bit in the configuration register). The expected PSL
is a programmable PSL value.
The RHPP also monitors the path signal label byte (C2) to detect path unequipped (UNEQ-P)
defect. UNEQ-P is declared when the accepted PSL is 00H and the expected PSL is not 00H.
UNEQ-P is removed when the accepted PSL is not 00H or when the accepted PSL is 00H and
the expected PSL is 00H. The accepted PSL is the same PSL value received for three or five
consecutive frames (selectable by the PSL5 bit in the configuration register). The expected PSL
is a register programmable PSL value.
The RHPP also monitors the path signal label byte (C2) to detect path payload defect indication
(PDI-P) defect. PDI-P is declared when the accepted PSL is a PDI defect that matches the
expected PDI defect. PPDI is removed when the accepted PSL is not a PDI defect or when the
accepted PSL is a PDI defect that does not match the expected PDI defect. The accepted PSL is
the same PSL value received for three or five consecutive frames (selectable by the PSL5 bit in
the configuration register). Table 7 gives the expected PDI defect based on the programmable
PDI and PDI range register values.
