A requesting terminal signals a call request (CALL) to a control unit of a first communications network. The control unit then determines whether sufficient capacity is available in the first communications network to establish the connection requested by the call request. In the event of insufficient capacity, the control unit transmits an overload message (DAT) to the requesting terminal. It only initiates an alternative establishment of the requested connection via another, second communications network after it receives an acknowledge message (ACK) issued by the requesting terminal.
Un terminal demandeur signale une demande d'appel à une unité de contrôle d'un premier réseau de communication. Ladite unité de contrôle détermine si ce premier réseau de communication peut établir la connexion demandée. Si le réseau ne peut établir la connexion, l'unité de contrôle transmet un message de surcharge au terminal demandeur. L'unité de contrôle ne cherche à établir la connexion via un second réseau de communication que si elle reçoit un message d'accusé de réception transmis par le terminal demandeur.
