ABSTRACT:
An overvoltage protection arrangement for preventing the occurrence of breakdown of a subscriber line control stage, independent of its structure and the integration technology used, by providing short-circuiting diodes in the control stage to prevent the occurrence of the overvoltage and providing voltage-limiting elements in those positions where overvoltage charge must be drained.
