Abstract: Techniques are disclosed for selecting transmission resources in a telecommunications system that comprises different networks, where the techniques are based on the quality of the waveform of transmitted media such as audio or video signals, in contrast to the quality of service of the network that transports the media. The problem with only using quality of service to determine which resources to allocate to a call is that quality of service does not guarantee that the quality experienced by the call's participants is satisfactory just because a component network's quality of service is satisfactory. For example, the end-to-end delay experienced in a VoIP network might be satisfactory for most data transfers, but might still be inadequate to control the echo experienced by telecommunications users. The disclosed techniques evaluate the waveform quality (i.e., in terms of loudness, noise, echo, and so forth) of media that is transmitted along a path and allocate alternative resources accordingly.

Abstract: A system for analyzing an availability of at least part of a communications network is provided. The network includes a set of network components, that are further divided into first and second subsets of network components. Each of the first and second subsets includes a plurality of different components in the network component set.

Abstract: A system for analyzing at least a portion of a telecommunications network is provided. The system includes a traffic flow analyzer 124 operable to (a) assign a plurality of network components to at least first, second, and third component sets 1216, 1220 and 1224, respectively, wherein the first and second component sets correspond to voice communication endpoints; (b) determine bulk voice traffic flows at least one of generated and received by the first and second component sets and passing through the third component set; and (c) based on the bulk voice traffic flow passing through the third component set, determine a requirement for the third component set to realize a selected grade and/or quality of service.

Abstract: The present invention realizes easy packaging of an optical module without using a molding machine and metal mold.

Abstract: The invention is a surface light source generator that can provide surface light with a high luminosity and uniformity and a small dispersion angle. The invention uses the light emitting diodes (LEDs) for industrial standard light bulb packaging as its basis. By redesigning the shape of the LED elements (e.g., hexagonal pillars, quadrangle pillars or triangular pillars) and disposing a plurality of same type LEDs together, a surface type illuminator comprised of many closely packed LED elements is formed. Using the convergent effect of the convex lens on top of the LED elements, the light dispersion angle is controlled within 15 degrees. Such a technique of packing many LED elements together can increase the unit area luminosity of the surface light source generator and, at the same time, achieve a high luminosity and uniformity.
