摘要： A noise management circuit for a Remote Terminal (RT) of a telecommunication system comprising first end-consumers (COEU) to which a Central Office (CO) is coupled via, amongst other, the remote terminal and first wires of a cable binder (CBO), and second end-customers (RTEU) to which the remote terminal is directly coupled via second wires of the same cable binder. The noise management circuit comprises a Power Spectral Density Shaper (PSDS) for arranging, within the low or protected frequency range, the frequency spectrum of the signals transmitted from the remote terminal to the second end-customers into a shape that is similar to the shape of the frequency spectrum of signals received at the remote terminal from the central office and intended to the first end-customers. The noise management circuit further comprises a noise generator (NIS) for injecting, within the high or unprotected frequency range, artificial noise into the signals received at the remote terminal from the central office and intended to the first end-customers. The protected and unprotected frequency ranges are separated by a split frequency (f1b).

摘要： The present invention relates to a method for identifying a crosstalk source interfering with a subscriber line, and comprising the step of collecting noise measurements performed over the subscriber line at consecutive time instances.
A method according to the invention further comprises the steps of:
- classifying said noise measurements into distinct measurement collections corresponding to respective ones of distinct crosstalk environments,
- time-averaging over a particular measurement collection, thereby yielding a particular time-averaged noise measurement,
- identifying said crosstalk source from said particular time-averaged noise measurement.
The present invention also relates to a network analyzer implementing such a method.
