Benefits of technology
"The present invention provides a chassis for telecommunications equipment that can integrate host computers, line-interface units, etc. from various suppliers. The chassis can be mounted in a cabinet or rack, or placed on a desktop or shelf. It provides proper power distribution, cooling, and integration for developers who bring their software solutions to market. The chassis also allows for easy insertion and removal of units, proper ventilation, and easy installation. Overall, the invention provides a convenient and flexible solution for integrating various components of telecommunications equipment."
Problems solved by technology
The prior switches of this type are disadvantaged in that all of the major subassemblies within the switch such as processors, power supplies, line-interface units, etc. are supported and interconnected by a single motherboard or backplane within the chassis.
This, of course, prevents customers from being able to select for incorporation into a given switch, processors and other subassemblies from specifics sources or vendors.
Conventional chassis designs do not allow for this flexibility.

Embodiment Construction
[0028] Referring to FIGS. 1 to 3 of the drawings, our chassis assembly comprises a cabinet shown generally at 10 which includes a top wall 110a, a bottom wall 10b and a pair of opposite mirror-image side walls 10c, 10c. Bottom wall 10b and side walls 10c, 10c are formed of a single piece of sheet metal with the side walls bent up at right angles to the bottom wall to form a generally U-shaped channel. Top wall 10a is a flat metal plate having depending side flanges (not shown) extending down just inside the upper edge margins of side walls 10c, 10c. That top wall is secured to the side walls by fasteners 12 extending through the side walls and threaded into the depending flanges of top wall 10a.
[0029] As best seen in FIGS. 2 and 3, the front and rear of cabinet 10 are open so that air can circulate through the cabinet. Also, the cabinet side walls 10c, 10c are provided with vertical arrays 14 of horizontal vent openings or slots to allow crosswise circulation of air through the cha...

A chassis assembly for containing a plurality of electronic units includes a cabinet including top, bottom, and opposite side walls, the front and rear of the cabinet being open. A pair of opposing vertical columns of spaced-apart stops projects from the interior surfaces of the side walls adjacent to the rear edges thereof, the corresponding stops in the pairs of columns being located opposite one another at the same elevation in said cabinet. The assembly also includes pairs of similar brackets each bracket pair adapted for securement to the opposite sides of an electronic unit to be contained in the chassis assembly. The brackets of each pair have rear ends shaped to interfit with corresponding stops in the columns of stops to set the elevation in the cabinet of the unit to which they are secured. The front ends of the brackets are releasably secured to the adjacent cabinet side walls so that said brackets are parallel to said top and bottom walls. A perforated closure member is releasably secured to the front of the cabinet to finish same and to provide a mounting surface for a logo.
Description
RELATED APPLICATION [0001] This application claims the benefit of Provisional Application No. 60 / 607,687, filed Sep. 7, 2004. This invention relates to telephone and data communication apparatus. It relates more particularly to an integrated chassis assembly to house such apparatus.BACKGROUND OF THE INVENTION [0002] Telecommunications switch / server apparatus is used to route message traffic over a network. Conventionally, such apparatus comprises a chassis or housing containing various electrical components and subassemblies that enable the switch to perform its functions, e.g. processors, memories, line-interface units and other network gear. Electrical connections to and from the switch are made by way of a multiplicity of data and telephony ports at the rear of the chassis. Cables plugged into those ports connect the switch to outside lines and to other units comprising the overall telecommunications system. [0003] The prior switches of this type are disadvantaged in that all of ...
