Abstract
The method is used in a telecommunication network wherein a central station (CS) is coupled to a plurality of residences (R ,R ,R ). One of the residences (R ) includes a termination unit (TU) which is coupled to the central station (CS) via a first port (P ). The residence (R ) also includes subscriber terminals, e.g. a personal computer (PC), a telephone set (TEL), a television set (TV) and a set-top box (STB) which are coupled to the termination unit (TU) via a second port (P ). The method includes amplifying an upstream signal (US) applied to the second port (P ) with an upstream gain value (UG) by means of an upstream signal amplifier (U-AMP ) which is included in the termination unit (TU). Thereby, an amplified upstream signal (AUS) is generated and provided to the first port (P ). The upstream gain (UG) is a compensation for the signal power attenuation of the internal transmission line (UA-Li) between the termination unit (TU) and one of the subscriber terminals which is in fact the in-house network attenuation. By this way cross-talk in the region of the internal transmission line at the subscriber terminals is reduced by reducing the differences between the signal power levels.
