The present invention concerns an adaptive headset interface for amplification and adjustment of signals between a random headset and a random terminal. The adaptive headset interface comprises digital signal processors, and is further equipped with a modem block over which the adaptive headset can be programmed by a call to a computer over the telephone net, whereby instructions as well as test signals are transferred between the computer and the adaptive headset interface, so that an adjustment is achieved which takes into account the signal transfer in relation to a reference telephone line corresponding to a given standard, or an adjustment which corresponds to the levels which apply for the relevant terminal to which the adaptive headset interface is connected.
L'invention concerne une interface adaptative pour casque d'écoute, permettant d'amplifier et de régler les signaux entre un casque et un terminal quelconques. L'interface adaptative comprend des processeurs de signaux numériques, ainsi qu'un bloc modem qui permet de programmer le casque en appelant un ordinateur par l'intermédiaire du réseau téléphonique. Les instructions et les signaux d'essai sont transmis entre l'ordinateur et l'interface de façon à réaliser un réglage qui tienne compte de la transmission des signaux par une ligne téléphonique de référence correspondant à une norme donnée, ou un réglage qui corresponde aux niveaux de fonctionnement du terminal auquel est connectée l'interface du casque.
