Broadcast television and satellite signal switching system and method for telephony signal insertion

摘要

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.
