Abstract
A digital subscriber line management system is provided. It comprises a device for calculating a set of values specifying a virtual noise mask. The device includes a receiver for receiving or otherwise obtaining a set of measurements of noise levels experienced at a digital subscriber line transceiver at each of a plurality of frequencies at different times, and a processor for calculating, in respect or each frequency, a combined value based on a plurality of measurements taken at different times, and for generating the set of values specifying a virtual noise mask in dependence upon the combined values.

A method of calculating a set of values specifying a virtual noise mask, the method comprising:
- receiving a plurality of measurements of noise levels experienced at a digital subscriber line transceiver at each of a plurality of frequencies at different times, and for each frequency calculating a combined value based on a plurality of measurements taken at different times;
- and
- generating the set of values specifying as virtual noise in dependence upon the combined values.
