US 6,453,153 B1 · Employing customer premises equipment in communications network maintenance

Abstract

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 platform 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.

Dependent claims

A method for enhancing the performance of a telephone network, the method comprising:

transmitting a first signal from a telephone network element to customer premises equipment (CPE) via a telephone network path;
measuring, at the CPE, loss in the first signal related to transmission via the telephone network path and generating, as a second signal, a calibration signal representing the measured loss;
receiving at the telephone network element the second signal generated by the CPE;
and
adjusting gain applied to a speech signal transmitted from the network element to the CPE based on the second signal.
