Title
(EN) DUAL MODE CORDLESS TELEPHONE IN AN OPTICAL TELECOMMUNICATION NETWORK
(FR) TELEPHONE SANS FIL BIMODE UTILISE DANS UN RESEAU DE TELECOMMUNICATIONS PAR FIBRES OPTIQUES
Abstract
(EN)
A subscriber terminal (22) within a business/residence (32) is in communications with a telecommunications network (12) through a fiber optic connection (33) to an optical network unit (20). Telephony signals are transmitted to and from the subscriber terminal to a user through a cordless telephone handset (26). During normal operation, the cordless telephone handset (26) operates in a cordless mode, passing telephony signals to a subscriber terminal telephone antenna (24) for transmission on the fiber optic connection (33). In the event of a power outage at the business/residence (32), the cordless telephone handset (26) switches to a wireless mode in order to continue to provide telephony communications. In the wireless mode, telephony communications are provided from the cordless telephone handset (26) to the telecommunications network (12) through a wireless telephone provider (14).
(FR)
Un terminal d'abonné (22) équipant un bureau ou une résidence (32) est en communications avec un réseau de télécommunications (12) au moyen d'une liaison par fibres optiques (33) et d'une unité de réseau optique (20). Des signaux téléphoniques transitent entre le terminal d'abonné et un utilisateur par l'intermédiaire d'un combiné sans fil (26). En cours de fonctionnement normal, le combiné sans fil (26) fonctionne en mode téléphonie sans fil, et transfert les signaux téléphoniques à l'antenne téléphonique (24) du terminal d'abonné en vue de leur transmission sur le lien en fibres optiques (33). En cas de panne de courant dans le bureau ou la résidence (32), le combiné téléphonique sans fil (26) passe en mode radio afin de continuer à assurer les communications téléphoniques. En mode radio, les communications téléphoniques sont assurées entre le combiné téléphonique sans fil (26) et le réseau de télécommunications (12) par l'intermédiaire d'un fournisseur de téléphonie sans fil (14).
