J2 Trace
Enable Trace: Generates the J2 Trace message defined when the Enable
Trace check box is selected. The Enable Trace check box has to be
selected to give access to the trace format and message. When the Enable
Trace check box is cleared, the J2 1-byte format is used and can be
configured from the LOP OH TX/RX (SONET) on page 266.
Format: Select the display format for J2. Choices are 16 and 64 bytes. The
default setting is 16-bytes.
Message: Enter the J2 value in 16-bytes or 64-bytes format. The default
message is EXFO SONET/SDH for 16 bytes and EXFO SONET/SDH
Analyzer low 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.
Note: 16-bytes selection allows typing up to 15 bytes (a CRC-7 byte will be added
in front for a total of 16 bytes). 64-bytes selection allows typing up to
62-bytes (<cr> and <L
bytes). J2 value should be ASCII suitable characters including the ITU T.50
Characters on page 57.
