Abstract

Une unité d'abonné (10) d'un système radiotéléphonique à accès multiple à répartition dans le temps (TDMA) est reconfigurée dans chaque intervalle de temps en une mosaïque de consommation de courant dans laquelle on diminue l'alimentation en courant des composants du circuit (12, 13, 21, 29, 56, 57, 58) qui ne sont pas nécessaires au traitement du signal de communication dans cet intervalle de temps. Pour minimiser l'ampleur des circuits nécessaires à la répartition des signaux de commande de la consommation de courant, on peut utiliser des techniques telles que la commande par la fréquence d'horloge (26, 30, 70) ou les commandes par interruption (31, 67, 68), pour modifier la consommation en courant des composants du circuit commandé, sans en fait commander les circuits d'alimentation en courant. Une logique à fréquence d'appel programmable commande la fréquence d'un générateur (58) de signal d'appel et un signal (70) de commande d'appel haute fréquence est produit et interrompu à la cadence de l'opération d'appel. On prévoit également une canalisation d'expansion principale pour pouvoir desservir les circuits en boucle d'abonnés avec le même équipement radio, et diminuer la consommation de courant par ligne.
