Abstract

Pour l'établissement d'une liaison dans un réseau de télécommunication (TKN), entre un premier abonné (TNA), qui dispose d'au moins deux terminaux (TEA, PPA) raccordés au réseau (TKN), et un autre abonné (TNB), des données cibles sont transmises, par l'intermédiaire d'un réseau de données (IPN) d'un système de traitement de données (PCA, CTS) du premier abonné (TNA), à la station de commande de services (SCP) du réseau (TKN), ces données cibles (ZDA) contenant les indications relatives au type et/ou à l'emplacement du terminal du premier abonné (TNA) avec lequel la liaison doit être établie. Sur la base de ces données cibles (ZDA), la station de commande de services (SCP) peut produire les informations cibles (DDA) qui sont nécessaires dans une station de commutation (SSP) du réseau (TKN) pour l'établissement d'une ramification de liaison avec le terminal du premier abonné (TNA). Cette ramification de liaison est ensuite raccordée avec une ramification de liaison avec l'autre abonné (TNB), pour créer la liaison.
