A device used for division of a transmission facility into two or more subchannels, either by splitting the frequency band into narrower bands or by allotting a common channel to several different transmitting devices one at a time
A complex piece of telephone equipment which combines the data stream of several leased lines for transmission over a single higher bandwidth leased line Multiplexors are used in the construction of WANs
A means ofdevice for connecting a number of data communication channels and combining the separate channel signals into one composite stream for onward transmission through a single link to a central data processor or information management system At its destination the multiplexed stream is de-multiplexed to separate the constituent signals Multiplexors are similar to concentrators in many respects, a distinction being that concentrators usually have a buffering capability to 'queue' inputs that would otherwise exceed transmission capacity See also Concentrator
