Abstract
(EN)
For a single telephone line (26) having plural telephone answering device (TADs) connected to it, a system of TADs is disclosed whereby only TAD (10) answers the telephone but all other TADs (20) connected to the telephone line are accessible and ativated by means of tones transmitted over the telephone line (26) by the caller. The caller is notified by the answering TAD (10) of the available tone codes which are then used to select the desired TAD. When a TAD (20) is selected by means of tones, the first TAD (10) is temporarily disconnected from the telephone line so that message privacy is maintained.
(FR)
Pour une ligne téléphonique unique (26) à laquelle sont reliés plusieurs dispositifs répondeurs (TAD) on décrit un système de TAD dans lequel seulement le TAD (10) répond à l'appel, mais tous les autres TAD (20) reliés à la ligne téléphonique sont accessibles et sont activés par des tonalités transmises sur la ligne téléphonique (26) par le demandeur. Le TAD (10) qui répond informe le demandeur des codes de tonalité disponibles, qui sont ensuite utilisés pour choisir le TAD souhaité. Lorsqu'un TAD (20) est sélectionné par des tonalités, le premier TAD (10) est momentanément déconnecté de la ligne téléphonique de manière à permettre une transmission confidentielle des messages.
