BROADCAST TELEVISION AND SATELLITE SIGNAL SWITCHING SYSTEM AND METHOD FOR TELEPHONY SIGNAL INSERTION

摘要

A system (10) switches multiple broadcast signals (12) from satellite (14) and cable (16) for transmission through a single coaxial cable (18) to television receivers (20) while managing use of the broadcast signals through telephony signal (22) insertion and passage of a telephony signal (22) and an RF signal (24) on the single coax (18) between a multiswitch (26) and a triplexer (28) operable with the receiver (20). A telephony interface (30) operates with the multiswitch (26) through a data access arrangement (DAA) device (36) for bringing outside telephone signals (22) to the multiswitch (26). The triplexer (28) includes a subscriber line interface circuit (SLIC) for providing telephony information to the receiver (20). The multiswitch (26) and telephony interface (30) route telephony information to the receiver (40).
