Self-terminating coaxial cable port
First Claim
1. A circuit for automatically terminating a user port in a coaxial cable system, comprising:
- a signal path extending from a user-side port toward a supplier-side port, the user-side port adapted to connect to a user device, the signal path comprising a conductor and a ground;
a passive signal sampler coupled to the signal path;
a comparator element in communication with the passive signal sampler, the comparator adapted to compare a line signal on the signal path to a reference signal and generate an output; and
a switch disposed in the signal path having a first state for directing the line signal to a ground path and a second state for passing the line signal, the first state and the second state being responsive to the output generated from the comparator.

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.

17. A coaxial cable connector assembly comprising:
-
a printed circuit board having first and second opposed major surfaces and first and second opposing sides, the opposed major surfaces being substantially parallel to a single plane and being bisected by a longitudinal axis, the first and second opposing sides being substantially parallel to the longitudinal axis; a signal path disposed on the printed circuit board, the signal path extending from an input portion toward an output portion; a passive signal sampler coupled to the signal path; a comparator element in communication with the passive signal sampler, the comparator 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 having a first state for directing the line signal to a ground path and a second state for passing the line signal, the first state and the second state being responsive to the output generated from the comparator; a body that receives the printed circuit board, the body having a first end and a second end opposite the first end, the first end and second end shaped so as to receive a first cable connector and a second cable connector respectively; an input terminal disposed within the body and in electrical contact with the input portion of the printed circuit board, the input terminal having an axis extending substantially parallel to the longitudinal axis; and an output terminal disposed within the body and in electrical contact with the output portion of the printed circuit board, the output terminal having an axis extending substantially parallel to the longitudinal axis. - View Dependent Claims (18, 19, 20, 21)

22. A method for automatically terminating a user port in a coaxial cable system, the method comprising the steps of:
-
providing a circuit comprising a signal path extending from a first port toward a second port, the first port carrying a bandwidth, the signal path comprising a conductor, a ground, and a switch disposed between the first port and the second port; passively sampling the bandwidth; comparing the sampled bandwidth to a reference value and, if the comparison exceeds a threshold value, positioning the switch to direct the signal path to the ground. - View Dependent Claims (23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35)
