A device that creates a single higher-speed transmission by combining and synchronizing two or more channels.
Equipment that combines 64Kbps channels and presents them to the user's terminal equipment as if they were a single larger bandwidth channel.
A device allowing a single application to use a number of aggregated B channels when a higher bandwidth than 64 k/bits is required.
A device that spreads a high-bandwidth information stream over multiple lower-speed transmission channels (e.g., a 1.5Mbps signal transmitted over twenty-four 64Kbps channels of a T-1).
An inverse multiplexer (often abbreviated to "inverse mux" or "imux") allows a data stream to be broken into multiple lower data rate communications links. An inverse multiplexer differs from a demultiplexer in that each of the low rate links coming from it is related to the other ones and they all work together to carry the same data. By contrast, the output streams from a demultiplexer may each be completely independent from each other and the demultiplexer does not have to understand them in any way.
