Title (EN) DEVICE CONTROL SYSTEM
(FR) SYSTEME DE COMMANDE DE DISPOSITIFS
Abstract: front page image
(EN)The control system employs the serving electronic stored program PBX (100) to regulate the operation of devices (LOO-LN), each of which is located at one of a plurality of sites, in accordance with one or more modes of operation as offered by an algorithm stored in the PBX memory. Each site is equipped with a control circuit to regulate the operation of the device located at the site. These control circuits (ECOO-ECn) are activated by the presence of an audio frequency on the telephone line (TOO, ROO) associated with each site. To minimize the impact of this scheme on the traffic capacity of the PBX time division switching network, all activated control circuits are concurrently connected to a single time slot, which supplies the required audio frequency.
(FR)Le systeme de commande utilise un programme electronique stocke PBX (100) pour regler le fonctionnement de dispositifs (LOO-LN), chacun d"eux etant situe a un emplacement faisant partie d"une pluralite d"emplacements ou lieux d"installation, selon un ou plusieurs modes de fonctionnement determines par un algorythme stocke dans la memoire PBX. Chaque lieu d"installation est equipe d"un circuit de commande pour regler le fonctionnement du dispositif situe a ce lieu d"installation. Ces circuits de commande (ECOO-ECn) sont actives par la presence d"une audiofrequence sur la ligne telephonique (TOO, ROO) associee a chaque lieu d"installation. Pour reduire au minimum l"impact de ce schema sur la capacite du trafic du reseau de commutations a division du temps PBX, tous les circuits de commande actives sont connectes simultanement a une seule tranche de temps, qui fournit l"audiofrequence requise.
