A method for coordinating and synchronizing a mode transition in a Discrete Multi-Tone (DMT) communication system operating over a range of tones. The method includes allocating a set of one or more of the tones in the range to serve as monitor tones for signaling the mode transition. The mode transition is signaled by transmitting a known transition sequence on the monitor tones over two or more successive symbol intervals while simultaneously transmitting data on at least some of the tones in the range other than the monitor tones.
