LOP RX (SDH, TU-3 path)
ERDI-CD (Enhanced RDI - Connectivity Defect): The ERDI-CD alarm is
declared when bits 5, 6 and 7 of the G1 byte contain the "110" pattern
in five consecutive frames.
ERDI-PD (Enhanced RDI - Path Payload Defect): The ERDI-PD alarm is
declared when bits 5, 6 and 7 of the G1 byte contain the "010" pattern
in five consecutive frames.
Note: Refer to Alarm/Error Measurements on page 47 for H/C LEDs, and Seconds
information.
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
respectively a carriage return and a line feed.
Enable LP-TIM (Trace Identifier Mismatch - Path): Allows enabling the
Trace Identifier Mismatch for the expected message defined. Enable
LP-TIM has to be enabled to give access to the expected trace format
and message. When Enable LP-TIM is disabled, the J1 1-byte is
available from the LOP OH RX (SDH, TU-3 path) on page 367.
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.
