Abstract:
An apparatus that transports a telephone signal and a broadband signal between a first location and a second location along a coaxial cable comprising:a first low pass filter at the first location dc coupling a first ring line of the telephone signal to an inner conductor of the coaxial cable, and dc coupling a first tip line of the telephone signal to an outer conductor of the coaxial cable;a first high pass filter at the first location ac coupling a first information wire of the broadband signal to the inner conductor of the coaxial cable, and ac coupling a first reference ground of the broadband signal to the outer conductor of the coaxial cable;a second low pass filter at the second location dc coupling a second ring line of the telephone signal to the inner conductor of the coaxial cable, and dc coupling a second tip line of the telephone signal to the outer conductor of the coaxial cable;a second high pass filter at the second location ac coupling a second information wire of the broadband signal to the inner conductor of the coaxial cable, and ac coupling a second reference ground of the broadband signal to the outer conductor of the coaxial cable.
