Abstract

L'invention concerne un système d'alimentation en courant d'appel dans des installations de télécommunications et notamment dans des installations de téléphonie, à commande centrale. Selon ce procédé, on prévoit à la place du générateur central de courant d'appel prévu en deux exemplaires et d'une forte puissance de sortie, uniquement des dispositifs à courant d'appel (RE I à RE Z) décentralisés prévus en un exemplaire pour chaque baie (G I1 à G Z) d'une installation et possédant une faible puissance de sortie, le rôle du dispositif de contrôle et de commutation associé aux générateurs centralisés de courant d'appel étant assuré par un dispositif de contrôle et de blocage présent déjà dans d'autres buts de contrôle. Application notamment aux réseaux téléphoniques.The invention relates to a system for supplying inrush current in telecommunications installations and in particular in telephony installations, with central control. According to this method, instead of the central inrush current generator provided in two copies and with a high output power, only decentralized inrush current devices (RE I to RE Z) provided in one copy are provided. for each bay (G I1 to GZ) of an installation and having a low output power, the role of the control and switching device associated with the centralized inrush current generators being provided by a control and blocking device present already for other control purposes. Application in particular to telephone networks.
