Abstract:
A system for providing an interface between a central computing apparatus providing output signals and at least one communications station providing input signals on a two-way signal path, the system comprising:a splitter-reflector preventing the output signals from the computing apparatus and the input signals from the communications station from passing to a signal distribution system and for coupling signals having a third frequency band from the signal distribution system onto the signal path; a first component positioned in the signal path adjacent the central computing apparatus for converting output signals from the central computing apparatus to signals having a first frequency band; a second component positioned in the signal path adjacent the communications station for modifying the converted output signals from the central computing apparatus to a frequency detectable by the communications station; a third component positioned in the signal path adjacent the communications station for converting the input signals from the communications station to signals having a second frequency band; and a fourth component positioned in the signal path adjacent the central computing apparatus for modifying the converted input signals from the communications station to a frequency recognizable by the central computing apparatus.
