An xDSL modem apparatus for installation on a telephone jack wall plate. The apparatus includes a port for transmitting and receiving carrier waves, a low-pass filtering means, a high-pass filtering means, and a band-pass filtering means. The low-pass filtering means isolates low-frequency component of a received composite carrier wave below a first frequency and transmitting the isolated low-frequency component of the composite carrier wave. The high-pass filtering means isolates a high-frequency component of the composite carrier wave above a second frequency. The band-pass filtering means isolates a power component of the composite carrier wave, the power component being in a frequency range between the first and second frequencies. The apparatus also includes an xDSL modem for demodulating the high-frequency component of the composite carrier wave in order to recover a computer readable bitstream and for modulating a high-frequency carrier wave with a received computer readable bitstream. The xDSL modem transmits the demodulated computer readable bitstream and the modulated carrier wave. The apparatus also includes a means for utilizing the power component of the composite carrier wave to provide operating power for the xDSL modem.
