Token-Ring Port Operation Modes
Each port can be independently configured to one of the following operating
modes.
Feature Function Benefit
Half-duplex
concentrator port
Port behaves like an
active MAU port for
classical Token-Ring. Connects to a single station in
half-duplex mode. Compatible
with older adapters.
Half-duplex station
emulation The Token-Ring port
is connected to a port
on a MAU. Connects to classical Token-
Ring segments with multiple
stations in existing
installations.
Full-duplex
concentrator port Connects to a single
station in full-duplex. 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.
Full-duplex station
emulation.
Connects to another
switch in full-duplex
mode. Allows easy connection
between switches.
RI/RO-like
connection
on Token-Ring ports
19 and 20 Allows connection
of the RI/RO port
from a MAU or CAU
directly to the
switch. Enables easy integration into
existing installations.
Automatic port
sensing of operating
mode The port senses
automatically which
mode to operate in. Makes installation easier and
faster.
Auto-configuration All
Token-Ring and
Ethernet switch ports
automatically sense
connection speed
and duplex mode.
Easy, plug and play installation
