Abstract
La présente invention concerne un agencement de commutation temporelle numérique. Un agencement de commutation temporelle numérique comprend au moins une paire de registres à décalage similaires, incident IR et sortant OR, respectivement; des portes de transfert TG et des moyens CL pour fournir des impulsions d'horloge. Des moyens de commande comprenant une mémoire à circulation TAM, circulant en synchronisme avec le registre incident, dans laquelle sont mémorisées des informations relatives aux instants de transfert requis de chacune des portes de transfert et une source d'identités de portes de transfert TGAM. Application aux structures de commutation MIC.
