Abstract

Système de test destiné à être utilisé avec un appareil servant à émettre et à recevoir des signaux de transmission téléphoniques multiples par l'intermédiaire d'une seule paire torsadée (100). Le système convertit un signal analogique venant d'une station de commutation (112) locale en un signal de 80 ksymboles/sec pour la transmission par l'intermédiaire d'une paire torsadée au moyen d'une carte de ligne (104). Un terminal distant (102) reconvertit le signal de 80 ksymboles/sec en un signal analogique classique pour l'utilisation dans un équipement de téléphone (108), de fac-similés ou d'autres équipements connexes classiques. L'équipement de test vérifie séparément tout le système, la partie de la carte de ligne du système, la partie du terminal distant du système, et la paire torsadée. On décrit aussi un circuit de couplage hybride de 2-à-4 fils (202) amélioré. Ledit circuit amélioré comporte deux enroulements 'd'aile' supplémentaires fixés au transformateur de sortie du circuit, les enroulements supplémentaires accroissant la force du signal reçu et annulant efficacement le signal en retour porvenant de l'amplificateur de sortie.
