Patent ID: 8154361

Claim:
A method for communicating over a coaxial cable network, the method comprising: identifying at least one port in the coaxial cable network that provides high mutual isolation among nodes of the coaxial cable network when the port is terminated with an impedance that matches a characteristic impedance of coaxial cable in the coaxial cable network; terminating the identified port with an impedance that is substantially mismatched with the characteristic impedance of the coaxial cable; and transmitting a signal from a first node in the network to a second node in the network with at least one of the first node and the second node being coupled to the coaxial cable network with an impedance that is substantially mismatched with the characteristic impedance of the coaxial cable, wherein at least one of an output impedance of the first node and an input impedance of the second node has a value that changes in response to whether the node is in a transmit state or a receive state.
