Ethernet multiplexer, connecting with computer serial port by LINK UP interface (we call local
end as Ethernet multiplexer), should be configured to ‘valid local end control’, otherwise,
should be configured to ‘valid remote control’ for remote end. Therefore, two Ethernet
multiplexers can be controlled on both ends simultaneously. NM topology are illustrated as
following,
NOTE: could install PC Agent software on NM computer as per users’ requirement.
Management information to Ethernet multiplexers at remote end is transmitted through the
overhead of optical signal. It will not take use of bandwidth of each port, the method of which
is out-of-band management.
