Title
(EN) LEAST COST ROUTING APPARATUS UPDATED VIA A BROADCAST SIGNAL
(FR) APPAREIL D'ACHEMINEMENT A MOINDRE COUT, MIS A JOUR VIA UN SIGNAL DE DIFFUSION
Abstract
(EN)
Telephone calls originating from terminals having respective routing apparatus (3) are transmitted via a common local network (4) and then via a subsequent network route which is determined by predetermined routing data stored in the routing apparatus (3). The stored information in a look-up table in each of the respective routing apparatus (3) is periodically updated by means of a multipoint broadcast via the common local network (4). The common local network (4) may be a cable network (4) carrying television transmissions so that the updating information may be encoded in a vertical blanking interval portion of the television broadcast signal. The preferred route information is prepared by a remote control centre (7) which also administers billing for calls routed in accordance with the routing information.
(FR)
Des appels téléphoniques, provenant de terminaux qui possèdent des appareils d'acheminement (3) respectifs, sont transmis via un réseau local (4) commun, puis via un acheminement de réseau subséquent, déterminé par des données d'acheminement définies, stockées dans ledit appareil d'acheminement (3). Les informations stockées dans la table de recherche de chaque appareil d'acheminement (3) respectif sont périodiquement mises à jour, au moyen d'une diffusion multipoint via le réseau local (4) commun. Ledit réseau local (4) commun peut être un réseau câblé (4) transmettant des émissions télévisées, de sorte que les informations de mise à jour peuvent être codées dans une partie verticale d'intervalle de suppression du signal d'émission télévisée. Les informations d'acheminement préférées sont préparées par l'intermédiaire d'un centre de commande (7) à distance, qui administre également la facturation des appels acheminés conformément aux informations d'acheminement.
