CA 2180721

In a telecommunication system, especially a telephone system comprising at least one electronic computer controlled telephone exchange, in its turn comprising time-spaced type switches, comprising a number of memory means in the form of matrices, a method and an apparatus for transferring, via inputs and outputs of said memory means, speech and data information in binary form between subscribers connected to the exchange, wherein, to considerably reduce the power consumption of the memory matrix as a whole, means are provided to activate only those memories which, for the moment, are intended to emit a corresponding output signal after that data has been written into same, and to cut off those portions of the memory matrix, which are not used for emitting output signals, in that no information is written into those, thus, not activated memories.

Procédé et appareil trouvant application dans un système de télécommunications tel qu'un système téléphonique comportant au moins un central téléphonique électronique commandé par ordinateur et doté à son tour de commutateurs de type temps-espace, comportant un certain nombre d'unités à mémoire (SS) sous forme de matrices. Le procédé et l'appareil servent à transférer, par l'intermédiaire des entrées et sorties desdites unités à mémoire, des informations de paroles et de données sous forme binaire entre les abonnés raccordés au central. Afin de réduire considérablement la consommation d'énergie de la matrice de mémoires dans son ensemble, on a prévu un dispositif destiné à n'actionner que les mémoires (SS) qui, temporairement, sont destinées à émettre un signal de sortie correspondant une fois que les données y sont introduites, et à déconnecter les parties de la matrice de mémoires qui ne servent pas à émettre les signaux de sortie, car aucune information n'est introduite dans les mémoires (SS) non actionnées.
