Abstract
An impedance matched lane reversal switching system including first and second transceiver pairs, each of the pairs including a transmitter connected to a receiver, the output of the transmitter connected to the input of the receiver and to a node, the node of each pair interconnected with a transmission line and a switching circuit for selectively enabling one of the transmitters of one of the transceiver pairs and disabling the other and selectively utilizing one of the receivers of the other of the transceiver pairs and not the other to selectively reverse an egress side and an ingress side of the lane.

An impedance matched lane reversal switching system comprising:
- first and second transceiver pairs, each of said pairs including a transmitter connected to a receiver, the output of the transmitter connected to the input of the receiver and to a node, the node of each pair interconnected with a transmission line;
- and
- a switching circuit for selectively enabling one of the transmitters of one of said transceiver pairs and disabling the other and selectively utilizing one of the receivers of the other of said transceiver pairs and not the other to selectively reverse an egress side and an ingress side of the lane.
An impedance matched lane reversal switching system comprising:
- first and second transceiver pairs, each of said pairs including a transmitter connected to a receiver, the output of the transmitter connected to the input of the receiver and to a node, the node of each pair interconnected with a transmission line;
- and
- a switching circuit for selectively enabling one of the transmitters of said transceiver pairs and disabling the other in one mode to selectively reverse an egress side and an ingress side of the lane.
A method of impedance matching and lane reversing a switching system comprising the steps of:
- providing first and second transceiver pairs, each of said pairs including a transmitter connected to a receiver, the output of the transmitter connected to the input of the receiver and to a node, the node of each pair interconnected with a transmission line;
- and
- selectively enabling one of the transmitters of one of said transceiver pairs and disabling the other and selectively utilizing one of the receivers of the other of said transceiver pairs and not the other to selectively reverse an egress side and an ingress side of the lane.
