Abstract
The cable interface unit in accordance with the invention allows use of the same wire in one cable both for base-band transmission of data between telecommunication equipment in full duplex form and also for transmission of an operating voltage (V) from one device to another. In the transmission unit, data is transmitted through a hybrid connection ( ) to a cable ( ). After the hybrid connection, the operating voltage (V) is also brought to the cable with the aid of a diplexer ( ). The hybrid connection separates the arriving data and conducts it to the receiver, where the data is shaped in an analog manner by correcting level distortions and thereupon in the digital signal processing a DECISION is made on what the received symbol is.
