A switcher has a plurality of input ports and a plurality of output ports. A plurality of port transceivers each have first and second I/O ports, an input port connected to an output port of the switcher and an output port connected to an input port of the switcher. Each port transceiver provides a first input signal path from the first I/O port to the output port of the transceiver, a second input signal path from the second I/O port to the output port of the transceiver, a first output signal path from the input port of the transceiver to the first I/O port, and a second output signal path from the input port of the transceiver to the second I/O port. Each port transceiver has a first state in which it propagates a signal received at its input port to its second I/O port and a signal received at its first I/O port to its output port and the first output signal path presents a high impedance to the first I/O port, and a second state in which it propagates a signal received at its input port to its first I/O port and a signal received at its second I/O port to its output port and the second output signal path presents a high impedance to the second I/O port.
A transceiver having first and second I/O ports for connection to a signal transmitting and receiving machine, an input port and an output port, and comprising a first receiver having an input connected to said first I/O port and an output connected to said output port of the transceiver, a second receiver having an input connected to the second I/O port and an output connected to the output port of the transceiver, a first driver having an input connected to the input port of the transceiver and an output connected to the first I/O port, and a second driver having an input connected to the input port of the transceiver and an output connected to the second I/0 port, the transceiver having a first state in which the first driver is disabled and presents a high impedance to the first I/O port of the transceiver and the second driver and the first receiver propagate signals from the first I/O port of the transceiver to the output port thereof and from the input port of the transceiver to the second I/O port, and a second state in which the second driver is disabled and presents a high impedance to the second I/O port of the transceiver and the first driver and the second receiver propagate signals from the second I/O port of the transceiver to the output port thereof and from the input port of the transceiver to the first I/O port.
A switcher having a plurality of input ports and a plurality of output ports and comprising a plurality of port transceivers each having first and second I/O ports, an input port connected to an output port of the switcher and an output port connected to an input port of the switcher, each port transceiver comprising means providing a first input signal path from the first I/O port to the output port of the transceiver, means providing a second input signal path from the second I/O port to the output port of the transceiver, means providing a first output signal path from the input port of the transceiver to the first I/O port, and means providing a second output signal path from the input port of the transceiver to the second I/O port, and each port transceiver having a first state in which it propagates a signal received at its input port to its second I/O port and a signal received at its first I/O port to its output port and the first output signal path presents a high impedance to the first I/O port, and a second state in which it propagates a signal received at its input port to its first I/O port and a signal received at its second I/O port to its output port and the second output signal path presents a high impedance to the second I/O port.
