Abstract

a. Poste téléphonique à clavier 1 comprenant deux émetteurs 2, 3 de signaux de numérotation en code à impulsions et en code à multifréquence, et des moyens 7 pour simultanément bloquer l'émission de l'émetteur d'impulsions et débloquer l'émission de l'émetteur à multifréquence ou inversement, et des moyens 6 pour détecter au moins un signal de supervision dit de tonalité initialisant l'une des phases d'établissement d'une communication. b. En réponse à la détection d'un signal de supervision, l'émetteur à multifréquence émet uniquement le signal associé à la première touche de la phase initialisée, puis en réponse à une nouvelle détection du signal de supervision, l'émetteur d'impulsions émet les signaux associés à la première touche et aux touches suivantes de la phase ou, en réponse à la non-détection du signal de supervision, l'émetteur à multifréquence émet les signaux associés uniquement auxdites touches suivantes. c. Poste téléphonique.
