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. The PDI-P defect 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 2 gives the expected PDI defect based on the
programmable PDI and PDI range register values.
