CA 2226079

A telephone exchange transmits audible signals to a subscriber line to indicate exchange or network conditions. The audible signals to be transmitted to the subscriber line are selected (means 15) from one or more available audible signal sources (14, 16, 17, 18, 19) according to the contents of a store location (20) for that subscriber line. Further store locations (25) are provided for each subscriber line to enable selection (means 21) of further audible signal sources (22, 23, 24) dependent upon the condition. The subscriber may alter the contents of his or her store location (20, 25) by dialling a special code.

Un central téléphonique envoie des messages sonores à une ligne d'abonné pour signifier des conditions de circonscription ou de réseau. Les signaux sonores à envoyer à la ligne d'abonné sont sélectionnés (15) dans une ou plusieurs sources de signal sonore disponibles (14, 16, 17, 18, 19) en fonction du contenu d'un emplacement d'enregistrement (20) pour cette ligne d'abonné. D'autres emplacements d'enregistrement (25) existent pour chaque ligne d'abonné afin de rendre possible une sélection (21) de sources complémentaires de signal sonore (22, 23, 24) et ce, en fonction de la condition signifiée. L'abonné a la possibilité de modifier le contenu de son emplacement d'enregistrement (20, 25) en composant un code spécial.
