Abstract

L'invention concerne la téléphonie. Un réseau intégré de commutation et de transmission, fonctionnant en multiplex temporel, comprend, entre autres, des groupes de lignes LG1-LGn reliés par des modules de liaison LM1-LMn, et un autocommutateur numérique qui est constitué par des modules de commutation SM. La structure modulaire de ce réseau, à commande entièrement décentralisée, facilite son extension. Application aux centraux téléphoniques.The invention relates to telephony. An integrated switching and transmission network, operating in time division multiplex, comprises, among others, groups of lines LG1-LGn connected by link modules LM1-LMn, and a digital switch which is constituted by switching modules SM. The modular structure of this network, with fully decentralized control, facilitates its expansion. Application to telephone exchanges.
