Function
Port behaves like an
active MAU port for
classical Token-Ring.
The Token-Ring port
is connected to a port
on a MAU.
Connects to a single
station in full-duplex.
Connects to another
switch in full-duplex
mode.
Allows connection
of the RI/RO port
from a MAU or CAU
directly to the
switch.
The port senses
automatically which
mode to operate in.
All Token-Ring and
Ethernet switch ports
automatically sense
connection speed
and duplex mode.
Benefit
Connects to a single station in
half-duplex mode. Compatible
with older adapters.
Connects to classical Token-
Ring segments with multiple
stations in existing
installations.
Allows high-performance
station and server connection
and allows high performance
server attachments with up to
97% improvement over a half-
duplex Token-Ring
connection.
Allows easy connection
between switches.
Enables easy integration into
existing installations.
Makes installation easier and
faster.
Easy, plug and play installation
