Abstract
A system for distributing broadband signals via twisted pair wiring is disclosed. Various aspects of the system involve use of a broadband signal distribution interface device and/or a broadband line driver. In one aspect, a broadband signal distribution interface device includes a broadband signal interface configured to receive broadband radio frequency signals, and a plurality of broadband signal connections configured to distribute broadband radio frequency signals. The interface device also includes circuitry defining an upstream signal path and a downstream signal path and including a gain control circuit and a slope control circuit each positioned along the downstream signal path. The circuitry is configured to accommodate downstream transmission of the broadband signals onto twisted pair wiring.

14. A method of adjusting output power of broadband radio frequency signals on twisted pair lines, the method comprising:
-
upon determining that a reference voltage level exceeds a predetermined level, deactivating an amplifier connected to a downstream path leading to a twisted pair connection and setting a radio frequency switch connected along an upstream path to a high attenuation condition; upon determining that the reference voltage is below a second predetermined level, activating the amplifier and setting the radio frequency switch to a low attenuation condition; and upon determining that the reference voltage exceeds a third predetermined level, activating the amplifier and setting the radio frequency switch to a low attenuation condition. - View Dependent Claims (15, 16, 17, 18)
