International Classification:

H04L 12/66

US Classification:

370356, 370401

Abstract:

A voice gateway () includes an input port () that receives a voice signal from an unbundled analog line () coupled to a Class 5 switch (). The voice signal is converted to a digital format by an analog-to-digital and digital-to-analog converting unit (). The voice signal is placed into a compressed format by a compressing/de-compressing unit () using a selected one of a plurality of compression ratios. The voice signal is placed into a transport frame by a packetizing/de-packetizing unit () according to a selected packet format. The voice signal is multiplexed with other voice signals by an output port (). The output port () 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 () and a residence customer premises ().

International Classification:

F28F 7/00

US Classification:

417173, 165908, 16510433, 361697

Abstract:

A method for constructing a thermal management system is provided herein. In accordance with the method, a fan () is provided which is adapted to provide a global flow of fluid through the device. A synthetic jet ejector () is also provided which is adapted to augment the global flow of fluid over the surfaces of a heat sink (). The ratio of the flow per unit time of the synthetic jet ejector to the flow per unit time of the fan is selected so as to achieve a desired level of heat dissipation.

Appl. No.:

9/579640

Inventors:

Ronald D. Lutz - Round Rock TX

Assignee:

General Bandwidth Inc. - Austin TX

International Classification:

H05H 720

US Classification:

361690

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.
