Title (EN) LONG DISTANCE TELEPHONE SWITCHING SYSTEM WITH ENHANCED SUBSCRIBER SERVICES
(FR) SYSTEME DE COMMUTATION TELEPHONIQUE A LONGUE DISTANCE AVEC SERVICES D'ABONNES AMELIORES
Abstract:
(EN) A long distance telephone switching system (34) is adapted to provide various enhanced subscriber services, such as an audio news and information service (45), conference calling (51), voice messaging (47), message storage and forwarding, and speed dialing, in addition to conventional long distance calling. Additional improvements include the use of prerecorded opening and closing scripts to facilitate the handling of operator-assisted calls, the retrieval of stored subscriber billing data prior to each call reoriginiation in order to detect instances of possible abuse, and the concatenation of subscriber-input authorization codes with access number data to allow the use of shorter authorization codes by the subscribers.
(FR) Un système de commutation téléphonique à longue distance (34) est adapté pour assurer divers services d'abonnés améliorés, tels qu'un service d'information et de nouvelles audio (45), conférence téléphonique (51), messagerie vocale (47), stockage et envoi de messages, et composition rapide de numéros téléphoniques, en plus des appels longue distance courants. Des améliorations supplémentaires comprennent l'utilisation de séquences types préenregistrées d'ouverture et de fermeture pour faciliter la prise en charge d'appels assistée par un opérateur, l'extraction de données mémorisées de facturation de l'abonné avant de redéfinir, pour chaque appel, la source d'origine de manière à détecter les cas d'abus éventuels, et la concaténation de codes d'autorisation d'entrée par l'abonné avec des données de numéro d'accès pour permettre aux abonnés d'utiliser des codes d'autorisation plus courts.
