Abstract
A digital subscriber loop (DSL) modem and methods for controlling a DSL modem are provided which support simultaneous voice and data communications, wherein the voice communication is provided in a first frequency range and the data communication is provided in a second, non-overlapping frequency range. A voice communication is detected in the first frequency range and the output power associated with the data communication in the second frequency range is reduced when a voice communication in the first frequency range is detected. Furthermore, the coding level associated with the data communication in the second frequency range may be increased when a voice communication in the first frequency range is detected. Also, the start frequency associated with data communication in the second frequency range may be increased when a voice communication in the first frequency range is detected.
