APPARATUS FOR TRANSPORTING HOME NETWORKING FRAME-BASED COMMUNICATIONS SIGNALS OVER COAXIAL CABLES

摘要

A method and apparatus for coupling a system propagating home networking communication signal over telephone lines to a system propagating television signal over a coaxial cable system to a television device. A three port adapter has a phone line port (120), a first coaxial cable port (122) and a second coaxial cable port (124). The first coaxial cable port (122) is coupled to the phone line port (120) through a low pass filter (128) and wideband balun (132) adapted to pass home networking communication signals while being rejecter television signals. The first coaxial cable port (22) is also coupled to the second coaxial port (124) through a high pass filter (130) while being rejected home networking communication signals. The first coaxial cable port (122) is coupled to the system propagating television signals over coaxial cable.
