A voice gateway (64) includes an input port (70) that receives a voice signal from an unbundled analog line (62) coupled to a Class 5 switch (52). The voice signal is converted to a digital format by an analog-to-digital and digital-to-analog converting unit (76). The voice signal is placed into a compressed format by a compressing/decompressing unit (80) using a selected one of a plurality of compression ratios. The voice signal is placed into a transport frame by a packetizing/depacketizing unit (84) according to a selected packet format. The voice signal is multiplexed with other voice signals by an output port (88). The output port (88) places the voice signal onto a selected one of a plurality of output lines in order to transport the voice signal in its transport frame to one of an office customer premises (12) and a residence customer premises (14).

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.

An apparatus to widen the light dispersion pattern of a light source shining through an overlay window from the viewing side of an electrical computer system. The overlay window is coupled to a panel of the system. The overlay window includes a transparent material, which has a first surface facing the light source and a second surface facing away from the light source to define a viewing side. An opaque material can be disposed on the first surface to partially cover the first surface to form a viewing window. A first diffusing mechanism is disposed on the first surface, and a second diffusing mechanism is disposed on the second surface. In response to the passage of the light output through the viewing window, the light dispersion pattern of the light output from the viewing side of the overlay window has a viewing angle of up to about 180 degrees.

A connector for coupling a communication link to a printed circuit board includes a plurality of pins and a shield. The pins electrically couple the communication link to an interface on the printed circuit board and generate electromagnetic emissions when supplied with an electric current. The shield is displaced outwardly from the pins and prevents at least some of the electromagnetic emissions from radiating outside the connector. The shield includes a plurality of tabs that extend into the printed circuit board when the pins are electrically coupled to the interface.
