Question

Quizplus · Accepted Answer

Discrete multitone (DMT) is the technology behind DSL systems that allows data to be transmitted over traditional copper telephone lines. DMT divides the available frequency spectrum into multiple sub-channels, each of which can carry data at different rates depending on the signal quality. This allows DSL systems to transmit data at high speeds over relatively long distances. Time division, amplitude division, and wavelength division are all technologies used in communication systems, but they are not specifically related to DSL.
