LOP-P (Loss Of Pointer - Path): For non-concatenated payloads, the
LOP-P alarm indicates that a valid pointer is not found in N consecutive
frames (where 8  N  10), or N consecutive NDFs (“1001” pattern) are
detected.

ERDI-PSD (Enhanced RDI - Path Server Defect): The ERDI-PSD alarm is
declared when bits 5, 6 and 7 of the G1 byte contain the “101” pattern
in five to ten consecutive frames.

ERDI-PCD (Enhanced RDI - Path Connectivity Defect): The ERDI-PCD
alarm is declared when bits 5, 6 and 7 of the G1 byte contain the “110”
pattern in five to ten consecutive frames.

ERDI-PPD (Enhanced RDI - Path Payload Defect): The ERDI-PPD alarm
is declared when bits 5, 6 and 7 of the G1 byte contain the “010” pattern
in five to ten consecutive frames.

PLM-P (Payload Label Mismatch - Path): The PLM-P is declared upon
receipt of five consecutive frames with mismatched STS signal labels.

UNEQ-P (Unequipped - Path): UNEQ-P is declared when the C2 byte
contains “00 H” in five consecutive frames.

Link (WIS): Link (WIS) is declared when at least one of the following
errors is present: AIS-P, LOF, PLM-P, SEF, LOP, or AIS-L.

Enable PLM-P/UNEQ-P (Payload Label Mismatch - Path / Unequipped -
Path): Allows enabling the Signal Label Mismatch for the expected
message defined as well as UNEQ-P monitoring.
J0 Trace
Displays the J0 value in 16-bytes format.
J1 Trace
Displays the J1 value in 16-bytes format.
Note: The represents the CRC-7 for a 16-bytes format.
