Abstract: The present invention relates to the field of telephony and specifically to a method for correcting the degradation of telephone signal quality caused by analogue lines. The invention describes managing, via the receiver, a specific correction of telephone signal degradation caused by the length of the analogue line between the parties. Said line length between the receiver and the telephone switchboard to which said receiver is connected is stored in the receiver. Advantageously, the line lengths between the receiver of the called party and the corresponding switchboard are stored, for example in the director of the apparatus. During the call, said line length is taken into account by a specific correction means for said correction inside the receiver.

Abstract: An audio appliance includes two external connections for connection to external loudspeakers, and includes means for establishing an electrical signal between the external terminals that is representative of an audio source in order to inject an excitation electric current into each external loudspeaker. Means are provided for incorporating a component at a “detection” frequency that is situated outside the audible spectrum in the electrical signal that is established between the external terminals, together with means for detecting an electric current flowing between the external terminals and having a frequency corresponding to the detection frequency. This is applicable in particular to systems comprising a mobile appliance and a fixed docking station incorporating a woofer and designed to receive the mobile appliance.
