1. A signal multiplex transmission system comprising:

  • (a) plurality of terminal units including a plurality of first terminal units for processing information signals to generate first information signals which are multiplexed to be transmitted as first multiplexed information signals in a first frequency band and a plurality of second terminal units for processing information signals to generate second information signals which are multiplexed to be transmitted as second multiplexed information signals in a second frequency band;

    (b) branch exchange means for allowing signal transmission between said first terminal units;

    (c) signal separation means for receiving the first and second multiplexed information signals, for separating the first multiplexed information signals from the second multiplexed information signals, and for transmitting the first multiplexed information signals to said branch exchange means and outputting the second multiplexed information signals; and

    mixer means, connected to said branch exchange means and said signal separation means, for receiving the first multiplexed information from said first terminal units through said branch exchange means and the second multiplexed information signals from said signal separation means, and for mixing the first and second multiplexed information signals to supply a composite signal to said first and second terminal units.
