1. A method for transmitting digital subscriber connection signals to an interface of an end user via a coaxial cable, wherein the coaxial cable has an overall frequency range configured for transmitting TV signals to the interface of the end user in an upper frequency range of the overall frequency range, wherein the interface comprises a customer terminal output, wherein the method comprises the following steps:
supplying, by a distribution point unit first balanced subscriber connection signals to the coaxial cable by a first transformation, directed toward the customer terminal output, of the first balanced subscriber connection signals into unbalanced subscriber connection signals by means of a distribution point balanced-to-unbalanced transformer device (balun device);
coupling the unbalanced subscriber connection signals into the coaxial cable into a lower frequency range of the overall frequency range, wherein the lower frequency range is below the upper frequency range without any overlap;
attenuating, by means of a filtering device, a reflection of the unbalanced subscriber connection signals in the coaxial cable;
a second transformation, directed toward the customer terminal output, of the unbalanced subscriber connection signals into second balanced subscriber connection signals by means of a balun device assigned to the interface, wherein the input impedance of the filtering device is adjusted with respect to reflections from the direction of the customer terminal output; and
separately making the second balanced subscriber connection signals available at the customer terminal output.
