Abstract

A wall mount filter for an xDSL network is provided. Wall mount filter includes a wall mount plate to which a connection port is coupled. The connection port is operable to electrically couple to an electronic device. A low pass filter circuit is coupled to a back surface of the wall mount plate. The low pass filter circuit is in electrical connection with the connection port. The low pass filter circuit is operable to electrically couple to a premises network and is sized to fit within a wall mount outlet. The wall mount plate is operable to be coupled to the wall mount outlet with a front surface facing outward and the low pass filter circuit contained within the wall mount outlet.
