ATions> 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)
