Abstract: A method for optimizing an electrical consumption of a residential gateway comprising at least one Foreign Exchange Station (FXS) port to which an analog telephone is connected via a line, the FXS port being configured from a pair of polarization points, referred to as default, which defines maximum voltage and current characteristics of the line, the method comprising storing at least one other pair of polarization points, referred to as economical, which defines maximum voltage and current characteristics of the line that are lower than those defined by the pair of default polarization points, selecting a pair of polarization points from the pair of default polarization points and the at least one pair of economical polarization points depending on the result of a comparative test on all these pairs of polarization points and configuring the FXS port from the pair of polarization points thus selected.

Abstract: The present invention concerns a method for optimising the electrical consumption of a residential gateway comprising at least one FXS port to which an analogue telephone is connected via a line, said FXS port being configured from a pair of polarisation points, referred to as default, which defines maximum voltage and current characteristics of the line that are predetermined so as to ensure correct operation of the telephone in on-hook or off-hook mode whatever the type of this telephone.
