> I'm a little vague on the term "MUX," ... MUX = Abbreviation for MUltipleXer, that is something that switches from line 1 to line 2 to line.... The Telephone Companies use high-speed multiplexers to sample, say 600 telephone lines (analog) one after the other, sample and briefly hold each voltage while it is converted to a digital pulse code, and send this signal down a single co-axial cable/microwave relay/optical fiber. At the other end, a DAC (Digital-to-Analog Converter)turns it back into a close approximation of the original voltage, and a DEMUX (guess what it does :-) splits it up into 600 telephone lines.
