Abstract
A communication system having first and second states for use with a shared transmission line composed of at least two conductors and composed of first and second transmission line segments connected to each other at a single connection point. In the first state, a termination is coupled to the single connection point and is operative to at least attenuate a signal propagated between the first and second segments. In the second state, a driver is coupled to the connection point and is operative to conduct a signal over the first and second segments.
Claims14
A device having terminating and transmitting states for use with a two-conductor transmission line, said device comprising:
- a connection port for connecting said device to a connection point of the two-conductor transmission line;
- a termination circuit couplable to said connection port and constructed for terminating a signal propagated over the two-conductor transmission line when said device is connected to the two-conductor transmission line;
- and
- a first driver operative to conduct a signal over the two-conductor transmission line when said device is connected to the two-conductor transmission line, said first driver having an input port selectively couplable to a signal source for coupling the signal source to the two-conductor transmission line, and an output port couplable to said connection port, wherein said device has a first state in which said termination circuit is coupled to said connection port and a second state in which the first driver output port is coupled to said connection port.
A communication system having first and second states for use with a shared transmission line composed of at least two conductors, the system comprising:
- first and second transmission line segments of the shared transmission line composed of at least two conductors connected to each other at a single connection point,
- a termination device selectively couplable to said single connection point and, when coupled to said connection point, operative to at east attenuate a signal propagated between said first and second segments of the shared transmission line composed of at least two conductors;
- a driver selectively couplable to said single connection point and, when coupled to said single connection point, operative to conduct a signal over said first and second segments of the shared transmission line composed of at least two conductors;
- wherein in the first state a termination is coupled to the single connection point, and wherein in the second state a driver is coupled to the single connection point.
