Abstract

L'INVENTION SE RAPPORTE A UN SYSTEME DE COMMUNICATION MULTIPLEX EN TEMPS PARTAGE. LE SYSTEME COMPREND UNE PAIRE HWLP, HWLP DONT LES EXTREMITES SONT CONNECTEES A UN CENTRAL COE ET DES POINTS INTERMECIAIRES SONT CONNECTES A DIVERS OFFICES LOCAUX LOE A LOE. UN DISPOSITIF EN BOUCLE LCE ECHANGE LES SIGNAUX ENTRE LA PAIRE ET LES LIGNES DE TRANSMISSION EXTERIEURES HWET A HWET. UN PROCESSEUR CPS ASSIGNE DES INTERVALLES DE TEMPS AU CIRCUIT REQUIS DE COMMUTATION. DES MOYENS D'ACCES A BOUCLE LAE COMMANDES PAR UN SIGNAL INTEROFFICE ASSURENT L'ACCESSION AUX INTERVALLES ASSIGNES. L'INVENTION S'APPLIQUE AUX SYSTEMES DE COMMUNICATION MULTIPLEX EN TEMPS PARTAGE DONT ELLE AUGMENTE L'EFFICACITE ET LA FIABILITE.
