If the optical data coupler detects an interruption on one of the sections, this
information is displayed immediately with the status "Link Down" on both sides of
the LS684 path via the Ethernet cable. As soon as the interruption is resolved, the
cable connection on both sides will be restored.
In addition to the usual display function, the optical data coupler signals the status
of the network connections, see table.
