摘要：1. Circuit arrangement for the overvoltage protection of electronic connectioncircuits, which are connected via a connection line (AL), for end stations intelecommunications technology, in particular teleprinter technology, comprising

overvoltage diverters (U1, U2) which are connected from the wires (a, b) of the connectionline (AL) to the earth terminal (M) of connection devices (G), and comprising a longitudinalinductance (L1, L2) and as and when required, a resistor (R1, R2) in each wire (a, b) whichtogether with a capacitor (C3; C1, C2), which is switched between the wires (a, b) or fromthe wires (a, b) to the earth terminal (M) of the connection device (G), form a voltagedivider, characterised in that at least one wire (a, b) of the connection line (AL) isconnected by means of a resistor (R3, R4) having a high resistance value to the earthterminal (M) of the connection device (G) which contains the connection circuit to beprotected.
