Abstract

Arrangement of circuits for the delimitation of voltages, especially for telecommunication or telephony centers, in order to protect against excessive voltages provisions connected with two-wire signal or conversation lines, as well as electronic link contacts, issuing and receiving dispositions, etc. ., controllable bypass sections formed by semiconductors are used, in each case with two connections, whose conductivity is low below a determined threshold voltage and is high above this voltage, characterized in that four equal branch lines are present, which in each case are connected in antiparallel in pairs with one of the connections of a signal or conversation line while all the connections of all the derivation legs are fused at a common point.
