Abstract

Programmable call discriminator. A telephone appliance (at) is connected to the serial line with a contact (with) that is closed or opened through a key. When the contact is open (with) a detector circuit is activated so that from the telephone appliance (at) only calls can be made by marking a certain number of figures. This is how can you avoid unauthorized persons using the telephone for inter-urban or international calls. The circuit is of low consumption and it is feeded from the telephone center when it is discussed to the headphone. (Machine-translation by Google Translate, not legally binding)
