Broadcast television and satellite signal switching system and method for telephony signal insertion
First Claim
1. A system for transmitting multiple radio frequency and telephony signals across a single cable, the system comprising:
- multiple input ports for receiving a plurality of radio frequency signals;
signal processing means operable with the input ports for processing the plurality of radio frequency signals for operation with a switch;
a plurality of switches wherein each one switch of the plurality of switches is operable with the plurality of processed radio frequency signals for providing a selected signal output therefrom in response to a control signal;
a telephony device for receiving a telephony signal, the telephony device electrically connected to a single conductor of the first end of the single cable for transmitting the telephony signal therethrough;
a master controller operable with the plurality of switches for providing the control signal thereto, the master controller operable with the telephony device for receiving telephony information therefrom;
a single cable having opposing first and second ends for transmitting radio frequency signals therebetween, the first end electrically connected with the one switch for receiving the selected radio frequency signal output;
a triplexer having an input port electrically connected to the second end of the single cable for receiving the radio frequency and telephony signals from the single line and providing separate satellite, cable television and telephony output signals to a receiver, the triplexer further having a controller for communicating with the master controller through the single conductor wire and an interface device for connection to the receiver; and
a baseband communications system operable with the controllers and the telephony device for modifying the telephony signal as characterized by the control signal for transmitting a modified telephony signal through a single conductor wire of the single cable.

Abstract
A system switches multiple broadcast signals from satellite and cable for transmission through a single coaxial cable to television receivers while managing use of the broadcast signals through telephony signal insertion and passage of a telephony signal and an RF signal on the single coax between a multiswitch and a triplexer operable with the receiver. A telephony interface operates with the multiswitch through a data access arrangement (DM) device for bringing outside telephone signals to the multiswitch. The triplexer includes a subscriber line interface circuit (SLIC) for providing telephony information to the receiver. The multiswitch and telephony interface route telephony information to the receiver.
