Circuit arrangement for the reduction of the power loss in the data operation of broadband - slics for the integrated speech - and data transmission (xdsl)

摘要

The present invention relates to a data transmission method as well as a transmitting device (14), from which via one and the same line (12), with utilization of different frequency ranges (5, 6) of different signals to a receiving device (15) can be transmitted, characterized in that the transmitting device (14) a first signal driver means (4a), which is activated when using a first frequency range (6) signals to the receiving device (15) are sent, and a second signal driver means (4b), which then is activated if, in addition to the under utilization of the first frequency range (6) transmitted signals using a second frequency range (5) signals to the receiving device (15) are intended to be sent.
