Abstract

CE RESEAU DE CONNEXION TEMPOREL EST DESTINE A CONNECTER DES LIGNES D'ABONNES ANALOGIQUES ET NUMERIQUES DANS UN CENTRAL TELEPHONIQUE. IL COMPORTE UN PREMIER MULTIPLEXEUR ET UN PREMIER DEMULTIPLEXEUR TEMPORELS QUI SONT RELIES D'UN COTE AUX VOIES EMISSION ET RECEPTION DES LIGNES A CONNECTER ET DE L'AUTRE COTE, PAR L'INTERMEDIAIRE D'UN BUS TEMPOREL, A UN SECOND DEMULTIPLEXEUR ET A UN SECOND MULTIPLEXEUR TEMPORELS DONT LES ACCES MULTIPLES SONT RELIES POUR FORMER UN CHEMIN DE CONNEXION DIRECT ET AU MOINS DEUX CHEMINS DE CONNEXION COMPORTANT UN CODEUR ET UN DECODEUR. LES MULTIPLEXEURS ET DEMULTIPLEXEURS SONT ACTIONNES DE SORTE QUE, ENTRE LES VOIES EMISSION ET RECEPTION DES LIGNES A CONNECTER POUR CHAQUE COMMUNICATION, SOIT INSERE PENDANT DEUX INTERVALLES DE TEMPS DU SIGNAL MULTIPLEX, OU BIEN LEDIT CHEMIN DE CONNEXION DIRECT, OU BIEN L'UN PUIS L'AUTRE DESDITS DEUX CHEMINS DE CONNEXION, SELON QUE LESDITES LIGNES A CONNECTER VEHICULENT DES SIGNAUX DE MEME NATURE OU DE NATURE DIFFERENTE. APPLICATION: COMMUTATION DANS LES CENTRAUX TELEPHONIQUES.
