ABSTRACT:
An intermediate repeater or a regenerative repeater has a circuit arrangement for the coarse protection against surge voltages, the arrangement comprising current supply separating filters for the remote feeding via a remote feed current path, fed via the inner conductor of a coaxial cable, which contain a low-pass filter, respectively. In the case of a circuit arrangement of this type, noise pulses, which a surge voltage arrester causes, are to be greatly reduced with respect to edge steepness. To this end, a series connection is provided containing the surge voltage arrester and an inductance, which series circuit, via a low-pass filter disposed outside of the remote feed current path, is connected between the low-pass filters of the current supply separating filters to the remote feed current path and to a connection of the outer conductors of the cables.
