SATURN USER NETWORK INTERFACE FOR 2488 MBIT/S
PLOPTREND:
The path loss of pointer removal (PLOPTREND) bit controls the removal of a LOP-P defect
when an AIS-P defect is declared. When PLOPTREND is set to logic 1, a LOP-P defect is
terminated when an AIS-P defect is declared. When PLOPTREND is set to logic 0, a LOP-P
defect is not terminated when an AIS-P defect is declared.
PERDI22:
The path enhance remote defect indication (PERDI22) bit selects the path ERDI persistence.
When PERDI22 is set to logic 1, a new path ERDI indication is transmitted by the THPP for at
least 22 frames. When PERDI22 is set to logic 0, a new path ERDI indication is transmitted
transmitted by the THPP for at least 12 frames.
PRDIEN:
The path remote defect indication enable (PRDIEN) bit selects between the 1 bit RDI code
and the 3 bits ERDI code. When PRDIEN is set to logic 1, the 1 bit RDI code is transmitted
transmitted by the THPP. When PRDIEN is set to logic 0, the 3 bit ERDI code is transmitted
transmitted by the THPP.
