Abstract

L'invention concerne un système de commande faisant appel à un répartiteur téléphonique et/ou à une boîte de liaison commutée. Ce système est équipé d'un bus, d'une pluralité de circuits d'interface de commutateur munis d'un convertisseur vocal A/N correspondant, d'un convertisseur vocal N/A correspondant, et d'un contrôleur E/S correspondant tous trois connectés, d'une pluralité de circuits d'interface téléphonique assortis d'un convertisseur vocal A/N correspondant, d'un convertisseur vocal N/A correspondant, d'un convertisseur vocal A/N de déclenchement et d'un contrôleur E/S tous quatre reliés entre eux. Lesdits convertisseur N/A, A/N et lesdits contrôleurs E/S sont connectés au bus de la même manière qu'un processeur qui se charge de commander via le bus le fonctionnement des convertisseurs N/A, A/N et des contrôleurs E/S. On établit alors via le bus précité une liaison par signaux vocaux entre un terminal déterminé à liaison montante et un terminal déterminé à liaison descendante. Ainsi, on passe automatiquement en mode répartition téléphonique et/ou en liaison commutée et la commande peut se faire à distance. Les avantages que l'on tire de cette invention sont : la réduction des coûts, l'amélioration des performances du répartiteur téléphonique et/ou de la boîte de liaison commutée de manière à en augmenter l'efficacité et la viabilité.
