Cable interface for data and power supply

That relate to using same line in a cable according to the diaphragm cable interface, which is filled a telecommunication device the base transmission between the data of the full-duplex groove, and further is used for working voltage (V) to transmit from the device to the device. The transmission device; the data (41) is transmitted through a mixed connected to the cable (23). The mixed connected; further - (44) working voltage (V) to transmit by the duplexer to the cable. The mixed connected with the contacted with the data separation and a transmitted to a receiver, a receiver, a system for adjusting the deformation layer, an form the data shaping, therefore in digital signal processing, receiving unit and condition of a decision.
