Title (EN) METHOD AND APPARATUS FOR TRANSMITTING SIGNALS OVER WIRE CONNECTIONS
(FR) PROCÉDÉ ET APPAREIL DE TRANSMISSION DE SIGNAUX SUR DES LIAISONS FILAIRES
Abstract:
(EN) A method and apparatus for transmitting data from a transmitter device to one or more receiver devices connected to the transmitter device via a respective wire connection, the transmitter device being operable to transmit signals onto the wire connections and a further wire connection at different tones, the method comprising: for each tone, measuring electromagnetic coupling between the further wire connection and each of the wire connections and using the measurements, identifying a wire connection that most strongly receives crosstalk interference from the further wire connection; based on the identifications, for each tones, allocating signals transmitted on the further wire connection as supporting signals for a particular wire connection; transmitting a first signal onto the particular wire connection that has been allocated a supporting signal; and transmitting a second signal onto the further wire connection, thereby to cause crosstalk interference in the particular wire connection transmitting the first signal.
(FR) La présente invention concerne un procédé et un appareil de transmission de données d'un dispositif émetteur à un ou une pluralité de dispositifs récepteurs liés au dispositif émetteur par l'intermédiaire d'une liaison filaire respective, le dispositif émetteur pouvant fonctionner pour transmettre des signaux sur les liaisons filaires et une autre liaison filaire à des fréquences différentes, ledit procédé comprenant les étapes suivantes : la mesure, pour la tonalité respective, d'un couplage électromagnétique entre l'autre liaison filaire et la liaison filaire respective et l'utilisation des mesures, l'identification d'une liaison filaire qui reçoit le plus fortement une interférence de diaphonie provenant de l'autre liaison filaire ; l'attribution, en fonction des identifications, pour la tonalité respective, de signaux transmis sur l'autre liaison filaire en tant que signaux de support pour une liaison filaire particulière ; la transmission d'un premier signal sur la liaison filaire particulière qui a été attribuée à un signal de support ; et la transmission d'un deuxième signal sur l'autre liaison filaire pour provoquer ainsi une interférence de diaphonie dans la liaison filaire particulière transmettant le premier signal.
