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. (2000-03-01)
