SONET Tabs
HOP RX (SONET)
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 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 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 consecutive frames.
J1 Trace
Received Message: Displays the J1 value in 16-bytes or 64-bytes
format. The <crc7> represents the CRC-7 for a 16-bytes format. The
last two bytes of a 64-bytes format, <C > and <L >, represent
R F
respectively a carriage return and a line feed.
Enable TIM-P (Trace Identifier Mismatch - Path): Allows enabling the
Trace Identifier Mismatch for the expected message defined. When the
Enable TIM-P check box is cleared, the J1 1-byte is available from the
HOP OH RX (SONET) on page 254. The Enable TIM-P check box has
to be selected to give access to the expected trace format and
message.
Expected Message: Allows entering the message that is expected.
J1 value should be ASCII suitable characters. The default message is
EXFO SONET/SDH for 16 bytes and EXFO SONET/SDH Analyzer high
order path trace test message for 64 bytes. However, with VCAT/LCAS
the default message will be EXFO followed by the VCG number (VCAT
and LCAS) and the SQ (VCAT only) number (for example
EXFO-VCG1-SQ0) for both 16 and 64 bytes formats.
Expected Format: Allows the selection of the format expected.
Choices are 16 or 64 bytes. The default setting is 16 bytes.
