Answer: DMT. Discrete multitone (DMT) is a method of separatinga Digital Subscriber Line (DSL) signal so that the usable frequency range isseparated into 256 frequency bands (or channels)of 4.3125 KHz each.DMT uses the fast Fourier transform (FFT) algorithm for modulation anddemodulation. Dividing the frequency spectrum into multiple channels allows DMTto work better when AM radio transmitters are present. Within each channel,modulation uses quadratude amplitude modulation (QAM). By varying the number of bits persymbol within a channel, the modem can be rate-adaptive. Both G.DMT and G.Lite use DMT.
