Abstract
A circuit for automatically terminating a user port in a coaxial cable system includes a signal path extending from a user-side port toward a supplier-side port, the signal path including a conductor and a ground. The user-side port is adapted to connect to a user device. The circuit further includes a passive signal sampler coupled to the signal path, and a comparator element in communication with the passive signal sampler. The comparator is adapted to compare a line signal on the signal path to a reference signal and generate an output. A switch disposed in the signal path has a first state for terminating the line signal and a second state for passing the line signal. The first state and the second state are responsive to the output generated from the comparator.
