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. The method is characterised in that it comprises the following steps: storing (1) at least one other pair of polarisation 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 polarisation points, selecting (2) a pair of polarisation points from the pair of default polarisation points and said at least one pair of economical polarisation points depending on the result of a comparative test on all these pairs of polarisation points, and configuring (3) the FXS port from the pair of polarisation points thus selected. The present invention also concerns a residential gateway, a computer program and storage means. |
