Description
Port
Displays the port number.

Select Section or Path.
Received Trace Mode
Sets the trace expected string:

Off/None: Trace mode is disabled.
 •
Auto: Uses the first string received from port at the other end as the baseline string. An alarm is raised when a string that differs from the baseline is received. For OC-N ports, Auto is recommended, since Manual mode requires you to trace the circuit on the Edit Circuit window to determine whether the port is the source or destination path.
 •
Manual: Uses the Current Expected String field as the baseline string. An alarm is raised when a string that differs from the Current Expected String is received.
