  • Solid-state ethernet by-pass switch circuitry
    Patent number: 7664012
    Abstract: A solid-state Ethernet by-pass switch includes a first connection that accepts transmit and receive lines from a first Ethernet device, a second connection that accepts transmit and receive lines from a second Ethernet device, a third connection that accepts transmit and receive lines from a third Ethernet device and a solid-state switching device having a normal state and a by-pass state. When configured in the normal state, the solid-state switching device couples the transmit and receive lines from the first connection to the transmit and receive lines from the second connection. When configured in the by-pass state, the solid-state switching device couples the transmit and receive lines from the first connection to the transmit and receive lines from the third connection.
