Classification: CPC H | IPC H

Claim 11:
12. Interface of an end user for use in a method according to claim 1, for transmitting digital subscriber connection signals to the interface via the coaxial cable, wherein the coaxial cable has an overall frequency range configured for transmitting TV signals to the interface of the end user in the upper frequency range of the overall frequency range, wherein the interface comprises the customer terminal output, wherein, with respect to unbalanced subscriber connection signals which are in the lower frequency range of the overall frequency range, said lower frequency range being below the upper frequency range without any overlap, and which are coupled into the coaxial cable, the interface is configured such as to cause:
a reflection of the unbalanced subscriber connection signals in the at least one coaxial cable to be attenuated by means of a filtering device, and
the second transformation, directed toward the customer terminal output, of the unbalanced subscriber connection signals into second balanced subscriber connection signals to be carried out by means of the 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
the second balanced subscriber connection signals to be separately made available at the customer terminal output,
wherein, in addition to a TV output, the interface comprises the customer terminal output and is configured to make TV signals available at the TV output in the upper frequency range and to make balanced subscriber connection signals available at the customer terminal output in the lower frequency range.
