Abstract

Circuit arrangement for a telephone exchange, in particular for a private exchange, intended to convert a flat number of a private line, arrived through a first input socket, into a corresponding subscriber number, which is to be characterized in a first output socket, for which through the input socket is selected, by means of a first wiring that can be connected to the crossover wire and existing for each call number, a first door circuit arrangement assigned to said wiring, governable from a direction through correspondingly arranged demodulators, and through which the subscriber number is characterized in the first output socket, by means of a second wiring connectable with cross-wire and assigned to the corresponding subscriber number, and of correspondingly arranged demodulators, characterized because for the inverse conversion of the subscriber number into the called number a, the subscriber number is selectable through a second input socket, and through the aforementioned second wiring connectable with cross wire, assigned in each case to the subscriber number to be converted, a second door circuit is selected that is assigned to said second wiring and through which the call number is then characterized by means of said first wiring connectable with cross-wire, assigned to the corresponding call number, and of a second output peg.
