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 <crc7> represents the CRC-7 for a 16-bytes format.
