The present invention customizes a network connection to customer premises equipment using a calibration signal. A network signal processor emits a tag signal indicating that a signal processing plafform is in use. Customer premises equipment (CPE) issues a calibration signal to the network signal processor based on detection of the tag signal. The customer premises equipment outputs the calibration signal to the network signal processor which measures the signal loss, adjusts the gain mapping and issues a calibration signal to the customer premises equipment. The customer premises equipment then estimates spectral shaping based on the calibration signal from the network signal processor and equalizes the receive path so that the signal processing platform is detected and implemented. Embodiments of the present invention are illustrative of a more general concept of the use of CPE as an agent in telephone network maintenance.

La présente invention personnalise une connexion réseau à un équipement privé d'abonné (EPA) au moyen d'un signal d'étalonnage. Un processeur de signal réseau émet un signal étiquette indiquant l'utilisation d'une plate-forme de traitement de signal. L'EPA envoie au processeur de signal réseau un signal d'étalonnage basé sur la détection du signal étiquette. L'EPA transmet le signal d'étalonnage au processeur de signal réseau, qui mesure l'affaiblissement du signal, règle le mappage de gain et envoie un signal d'étalonnage à l'EPA. L'EPA estime ensuite la forme spectrale en fonction du signal d'étalonnage provenant du processeur de signal réseau et égalise le trajet de réception de manière que la plate-forme de traitement de signal soit détectée et mise en oeuvre. Les versions de la présente invention illustrent un principe plus général d'utilisation d'un EPA comme agent dans l'entretien d'un réseau téléphonique.
