Abstract

Improvements introduced in the telephone circuits that allow the call warning in the busy devices or in conversation, characterized by having inserted on the circuit of the preselector of each device a coil capable of revealing the low voltage pulses that arrive at the device occupied from a third calling device, through the closed or open circuits for testing and blocking the line selectors, a capacitor capable of being charged by the aforementioned low voltage impulse, a coil connected to one of the cables of the line of the apparatus and arranged in a mutual induction manner with the coil mounted on the preselector and capable of receiving and amplifying the impulse that reaches the coil of the preselector and sending it to the headset of the apparatus.
