Abstract
The present invention is a switching system for a broadband network operating above five megahertz. The system connects to a first and second network through appropriate network connections. There are four components in the switching network. A first component with a first common connection, a first A branch, and a first B branch, the first common connection is connected to the first network terminal. A second component has a second common connector and a second A and B branch. The second common connector is connected to the second network terminal. The third component has a third A and B branch and one third common connector. The third A branch is connected to the first A branch. The third B branch is connected to the second B branch. The third common connector is connected to a first device terminal of a device. The fourth component has a fourth A and B branch and a fourth common connector. The fourth B branch is connected to the second B branch. The fourth common connector is connected to a second device terminal of the device. The fourth A branch is connected to the first A branch. One or more of the first, second, third and fourth components is chosen to be a switch or splitter and configured to change the flow of electromagnetic power through the first and second terminals of the device and the first and second network terminals.
