Solid-state ethernet by-pass switch circuitry
First Claim
1. A solid-state Ethernet by-pass switch comprising:
- 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 circuit having a normal state and a by-pass state, the solid-state Ethernet by-pass switch deriving power from Ethernet signals without needing external power,such that, when configured in the normal state, the solid-state switching circuit couples the transmit and receive lines from the first connection to the transmit and receive lines from the second connection, andwhen configured in the by-pass state, the solid-state switching circuit couples the transmit and receive lines from the first connection to the transmit and receive lines from the third connection.

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.

6. A solid-state Ethernet by-pass switch having a normal state and a by-pass state, the solid-state Ethernet by-pass switch comprising:
-
a first connection that accepts transmit and receive lines from a first Ethernet device; a second connection that accepts primary transmit and receive lines from a second Ethernet device; a third connection that accepts transmit and receive lines from a third Ethernet device; a fourth connection that accepts secondary transmit and receive lines from the second Ethernet device; a first solid-state switching device coupling the transmit line of the first connection to the receive line of the second connection when configured in the normal state and coupling the transmit line of the first connection to the receive line of the third connection when configured in the bypass state; a second solid-state switching device coupling the transmit line of the third connection to the receive line of the fourth connection when configured in the normal state and coupling the transmit line of the third connection to the receive line of the first connection when configured in the by-pass state; a third solid-state switching device coupling the transmit line of the second connection to the receive line of the first connection when configured in the normal state and opening the transmit line of the second connection when configured in the by-pass state; and a fourth solid-state switching device coupling the transmit line of the fourth connection to the receive line of the third connection when configured in the normal state and opening the transmit line of the fourth connection when configured in the by-pass state. - View Dependent Claims (7, 8, 9)
