Abstract: 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.

Abstract: 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).

Abstract: A backplane (11) of a telecommunications chassis includes a pair of controller slots that can receive respective controller modules. The backplane (11) also has a plurality of module slots that can receive respective telephony modules. Each of the pair of controller slots is connected by a plurality of buses to each of the plurality of module slots. The backplane (11) provides the ability to place any module type into any of the plurality of module slots.

Abstract: According to one embodiment of the invention, an insertion/extraction apparatus for circuit cards includes a card cage having at least one card guide and at least one channel, at least one circuit card engaged with the card guide, and at least one ejector pivotally coupled to the circuit card. The ejector has protrusions proximate a first end that are operable to engage the channel and a fastener disposed through an aperture in the ejector.

Abstract: 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.

Abstract: A system for housing telecommunications equipment includes a plurality of vertically disposed chassis, each chassis having a top that is substantially closed, two sides, two ends, and a base, wherein the top of each chassis is adapted to receive the base of an adjacent chassis. At least one vent is formed in each chassis adjacent the base for allowing air to enter the chassis, and at least one of the ends and one of the sides of the chassis are formed such that air may exit the chassis. The vent is disposed between the base and a portion of the chassis selected from the group consisting of either of the ends and either of the sides, and the vent is nonplanar in relation to that portion. More specifically, the chassis may be vertically disposed with substantially zero gap, and the vent member may be either an angled vent member or a notched vent member.
