Abstract

1. An input arrangement (2) for a line terminal device (1) connected at the receiving end of a communications transmission system, with direct current remote feeding via the inner conductors (a) of coaxial lines (a, b) which are combined together with symmetrical lines (17) in a cable with a common cable outer conductor (18), comprising an input switch (L1, C1) in the line terminal device (1), which is connected via a triaxial intersection point (12) to a triaxial line (16) which consists of one of the coaxial pairs (a, b) and a screen (c) which is coupled to the cable outer conductor (18), characterised in that a coaxial line (20) is surrounded by an electrically conductive housing (21) connected to the screen (c) of the triaxial line (16) at the input end and to the housing (10) of the line terminal device (1) at the output end, that the coaxial line (20) and the housing (21) of the input arrangement (2) are designed to form at least one filter element (28) comprising at least one ferrite ring (22) is slipped onto the coaxial line (20) and at least one shunt capacitor (Ca) is arranged between the outer conductor (27) of the coaxial line (20) and the housing (21).
