Token Ring Port Operation Modes

Each Token Ring port may operate in one of the following modes:
•
Half-duplex concentrator port
The port behaves like an active MAU port for classical Token Ring. Connects
to a single station in half-duplex mode. This is also known as Token Passing
(TKP) port mode. Compatible with older adapters.
•
Half-duplex station emulation
The port is connected to a port on a MAU. Connects to a classical Token Ring
segment with multiple stations. This is also known as Token Passing (TKP)
station mode.
•
Full-duplex concentrator port
Connects to a single station or to another switch in full-duplex mode. This is
also known as Transmit Immediate (TXI) port mode.
•
Full-duplex station emulation
Connects to another Token Ring switch. This is also known as Transmit
Immediate (TXI) station mode.
•
RI/RO-like connection
Allows connection of the RI/RO port from a MAU or CAU directly to the
switch. (STS16-20RM on ports 19 and 20, STS16-20FRM on all 20 fiber
ports.)
The mode of operation can be configured manually or sensed automatically with the
exception of RI/RO, when equipment is connected to the port. The media speed (4 or
16 Mbps) can also be manually configured or automatically sensed in all port modes.
