J2 Trace
Enable Trace: Enable Trace, when enabled, generates the J2 Trace
message defined. Enable Trace has to be enabled to give access to the
trace format and message. When the J2 Trace is disabled, the J2 1-byte
format is used and can be configured from the LOP OH TX/RX (SDH,
TU-3 path) on page 367.
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 as selected.
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 (<C
bytes). J1 value should be ASCII suitable characters including the ITU T.50
Characters on page 57.
