Abstract

Emetteur de numéros d'appel téléphoniques et poste opérateur équipé d'un tel émetteur. L'émetteur comporte, outre les circuits usuels et incorporée au poste 1, une memoire temporaire 9 associée à un groupe de deux filtres 8, aptes chacun à détecter sélectivement un signal de tonalité, et à un circuit d'inscription de pauses 10. Tout numéro composé individuellement peut être mémorisé avec inscription automatique et sélective des pauses correspondantes. A la restitution, l'apparition d'une pause provoque l'inhibition des émissions d'impulsions jusqu'à détection d'un signal de tonalité activant un circuit de relance Le poste 1 peut aussi comporter une mémoire-répertoire 4. Applications : Postes téléphoniques d'abonnés.
