HOP TX (SONET)
J1 Trace
Format: Displays the J1 value in 16-bytes or 64-bytes format. Enter the
J1 trace value in 16 or 64-bytes format as selected. The default setting is
16-bytes.
Message: Enter the J1 trace value in 16 or 64 bytes format as selected.
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.
Enable Trace: Generates the defined J1 Trace message defined except
for Intrusive mode (see Overwrite) 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 J1 1-byte format is used and can be
configured from the HOP OH TX on page 254.
Overwrite: Available with SONET/SDH Intrusive through mode only
(optional). Overwirte is not available on FTB-8105/FTB-8115. The
Overwrite check box when selected, generates the defined J1 Trace
message. The Enable Trace check box has to be selected to give
access to the trace Format, Message, and Overwrite.
