ABSTRACT:
A line device for transmission lines having coaxial cables for the transmission of signals, in particular digital signals or analog signals, employs an input equalizer in the form of a line section connected in parallel or in series to the transmission path, a first switch or dividing network for dividing the transmission path into a communications transmission path and a long distance current supply path, a regenerator in the communication transmission path, a series circuit connected in the long distance supply path including a first low pass filter, an element for producing a voltage drop for the current supply of the regenerator and a second low pass filter. A second switch or dividing network rejoins the communications and long distance supply paths and an output equalizer in the form of an additional line section is connected in parallel to the transmission path or in series with the transmission path. The line sections have at least two sub-sections of different wave resistances and at least one of the sections is adjustable during the manufacturing process in respect of its wave resistance. A terminating resistance is provided for each line section.
