1. For use in a network comprising a first business machine and a second business machine employing interchange of binary signals, said binary signals having signal characteristics conforming to one of a plurality of predefined electrical interfaces, an interface subsystem for receiving said binary signals from said second businesses machine, said interface subsystem comprising:

  • a universal interface unit for receiving and processing said binary signals, said universal interface unit having;

    a port having a predetermined common electrical interface for receiving binary signals;

    a communications processor for processing said binary signals; and

    receiver means connected by signal lines between said communications processor and said port for receiving and conditioning said binary signals so that said binary signals may be processed by said communications processor; and

    a plurality of cables corresponding to said plurality of predefined electrical interfaces so that each cable corresponds to a unique predefined electrical interface, each cable for being individually connected between said port and said second business machine for conveying said binary signals to said port from said second business machine, each cable having a unique means for preconditioning said binary signals having signal characteristics conforming to one of said unique predefined electrical interfaces so that said binary signals have new signal characteristics conforming to said predetermined common electrical interface of said port.
