An electronic filter has an input connector adapted for electrical connection to a complementary output connector of an asymmetrical digital subscriber line. The input connector has an input voltage node for providing electrical input signals to the electronic filter. Similarly, the filter has an output connector adapted for electrical connection to a complementary input connector of a data receiving device. The output connector has an output voltage node for providing electrical output signals from the electronic filter. The filter selectively passes frequency components of the electrical signals, frequency components below a predetermined corner frequency passing from the input connector to the output connector, frequency components above the predetermined corner frequency not passing from the input connector to the output connector.
