Method and apparatus for connecting satellite receiver telephone modems over coaxial cable

摘要

A method and apparatus for coupling an Integrated Receiver Decoder (IRD) to a telephone line via a coaxial cable used for delivering direct broadcast satellite signals to the IRD. One embodiment comprises a port coupler, coupled to a telephone line and to the coaxial cable, and a client unit, coupled between the port coupler and the IRD, wherein the port coupler connects the IRD to the direct broadcast satellite signals and connects the IRD to the phone line via the client unit, and at least satellite signals, satellite control signals, telephone data signals, and telephone system protocol signals travel on the coaxial cable between the client unit and the port coupler.

1. An apparatus for coupling an Integrated Receiver Decoder (IRD) to a telephone line via a coaxial cable used for delivering direct broadcast satellite signals to the IRD, comprising:
a port coupler, coupled to a telephone line and to the coaxial cable; and a client unit, coupled between the port coupler and the IRD; wherein the port coupler connects the IRD to the direct broadcast satellite signals and connects the IRD to the phone line via the client unit, and at least downconverted direct broadcast satellite signals in a first frequency band, satellite control signals in a second frequency band, telephone data signals in a third frequency band, and telephone system protocol signals in a fourth frequency band travel on the coaxial cable between the client unit and the port coupler, wherein the telephone system protocol signals are translated to the fourth frequency band from at least a portion of the second frequency band when the telephone system protocol signals are present on the coaxial cable.
