Abstract
Line equipment, preferably a line terminating device, in a communications system including transmitting and receiving circuits to which are connected transmitting lines and receiving lines includes at least one receiving circuit that is equipped with a circuit arrangement for compensating crosstalk. A single circuit arrangement effects the compensation of crosstalk between a plurality of transmitting lines and a receiving line. For compensation, a reference signal of the transmitted signal is branched off from each transmitting circuit and an adaptive filter simulates a compensation signal. The individual compensation signals are mixed into the received signals through the subtraction inputs of a subtraction circuit. Part of the output signal of the subtraction circuit is fed to the control signal inputs of the adaptive filters, the other part is processed further to become the received signal.
