concentrator
     
         A device that combines the data streams from
        many simultaneously active inputs into one shared channel in
        such a way that the streams can be separated after
        transmission.  The concentrator's output bandwidth must be at
        least as great as the total bandwidth of all simultaneously
        active inputs.  A concentrator is one kind of {multiplexing}
        device.
     
        For example, a concentrator may be used to connect 24 2400 bps
        TTYs to a host via a 57600 bps channel.
