Abstract

A system for transmitting information at high speed to a subscriber'"'"'s digital terminal (30). According to the invention, said system comprises at least passive adapter means (10, 10′) between an xDSL link (1) for high speed transmission of information and a mains voltage electricity network (2) having at least said subscriber'"'"'s digital terminal (30) connected thereto. The invention is applicable to high speed transmission over the terminal portion of a subscriber line.

Claims

1. A system for transmitting information at high speed to a subscriber'"'"'s digital terminal (30), characterized in that said system includes at least passive adapter means (10, 10′

) between an xDSL link (1) for transmitting information at high speed and a mains voltage electricity network (2) to which at least said subscriber'"'"'s digital terminal (30) is connected.

2. A transmission system according to claim 1, characterized in that said passive adapter means (10, 10′

) are disposed firstly on input to the mains voltage electricity network (2), and secondly at the input to said digital terminal (30).

3. A transmission system according to claim 1 or claim 2, characterized in that said system is suitable for transporting xDSL modulation over the mains voltage electricity network (2) to the digital terminal (30) via said passive adapter means (10, 10′

).

4. A high speed transmission system according to any one of claims 1 to 3, characterized in that said system is suitable for transmitting said information directly via said passive adapter means (10, 10′

).

5. A passive adapter device (10, 10′

) configured for being associated with the transmission system of any one of claims 1 to 4, the device being characterized in that it comprises at least;

low frequency filter means (C1, C2) on the mains voltage electricity network (2); and

isolator means (TR) between the mains voltage electricity network (2) and the xDSL link (1).

6. A passive adapter device (10, 10′

) according to claim 5, characterized in that said device (10, 10′

) includes matching means (C3) for matching impedance to a telephone set (21).
