Abstract

Device for identification and control of telephone calls, characterized in that it comprises an electronic circuit, capable of being connected to a line of telephone equipment, so that properly programmed said circuit, can prevent any type of call: urban, interurban, national or international, together and/or independently; said circuit comprises an input rectifier and a set of stabilizing transistors, which receive power when picking up the handset, so that when making the dialing, another transistor will conform the pulses, which are sent through a logic gate to a counter of impulses, with decimal output, so that a positive voltage appears on the corresponding output terminal, passing through the corresponding diode to a scale, so that if the output bridge is connected to one of the stabilizer transistors, the voltage passes to it, so that the power supply will stop driving through the first transistor, and the subscriber line will be placed on high impedance, preventing new markings, thus avoiding the call.
