-25- A telecommunication network having a switching system connected to a called station by a line that provides notification to a called party of information relating to an incoming call. This information generally consists of the called number, but may also include an extension or other code. The called party identification is delivered to the called telephone station set during the silent period after ringing, or, advantageously before ringing starts. A signal (e.g.,FSK) is sent to the called telephone station set shortly before the ringing signal is sent to the called station. A converted at the customer premise receives the FSK signal and demodulates it. A control unit connected to the converter then causes the called DN to be displayed, may cause a distinctive ring to be made, or take other action depending upon its program.
Réseau de télécommunication comportant un système de commutation relié à un poste appelé par une ligne qui donne à un appelé des renseignements sur un appel d'arrivée. Ces renseignements comprennent généralement le numéro appelé, mais peuvent aussi comprendre un numéro de poste ou un autre code. L'identification de l'appelé est transmise au poste téléphonique appelé pendant l'intervalle de silence suivant la sonnerie ou, de préférence, avant que le téléphone sonne. Un signal (p. ex. : FSK) est envoyé au poste téléphonique appelé un peu avant l'envoi du signal de sonnerie au poste appelé. Un convertisseur chez le client reçoit et démodule le signal FSK. Une unité de commande reliée au convertisseur permet l'affichage du numéro de poste, peut donner une sonnerie distincte ou prendre toute autre mesure selon son programme.
