Abstract

System to insulate a subscriber in sense incoming in a telecommunication central. Consists of using an electrically unidirectional device for the feeding and polarization current of the subscriber apparatus as well as the conversation current to the superposal that allows the passage of the call warning current towards the subscriber apparatus, which may include the device at any point of the subscriber line and especially on the regulation of the subscriber line, through a pin, all of them without any modification in the central equipment. It has applications in call communication systems (telephone or telegraph) in which the polarity of the line threads of the subscriber in the provision of making a call is different from polarity at the time of being called.
