Claim Text:
1. A method for estimating a position where noise enters a telecommunications transmission line the line having a first communications equipment connected to a first end of the line and a second communications equipment connected to a second, opposite end of the telecommunications transmission line, the method comprising the following steps: receiving, via the telecommunications transmission line, a first result of a measurement of a noise level at the first end of the telecommunications transmission line made by the first communications equipment; receiving a second result of a measurement of a noise level at the second end of the telecommunications transmission line made by the second communications equipment; and generating an estimate of the position where the noise enters the telecommunications transmission line based on the relationship between the first and the second noise level measurement results where the first and second noise level measurements are made at the same frequency or frequency band and the frequency or frequency band falls within a transmit band of at least one of the first and second communications equipment.
