Abstract: A system that provides supporting software to allow facsimile documents to be transferred via non-traditional mechanisms such as electronic mail, the Internet, and V.32 or other non-fax modems. The system allows facsimile documents to be transferred by computer without intermediate G3 facsimile hardware and without performing time-consuming compatibility determinations. The system also provides for cross-platform document transmissions.

Abstract: A System for Voice Playout in an Unsynchronized Packet Network for use with isochronous and asynchronous data transmission over a communication network having at least one receiving unit and at least one transmitting unit each having independent clocks. A FIFO voice codeword storing device in the receiving unit removes timing jitter from incoming packets--and receives voice packets from a data network. A phase continuous packet clock thereafter removes packets from the FIFO voice codeword storing device which is synchronized to the incoming data rate using the fill status of the FIFO voice codeword storing device as a frequency control signal. A continuous phase resampler removes timing frequency offset without causing packet slips or loss of data. The transmitter inserts the contents of a free running packet counter into each transmitted packet, allowing the receiver to detect lost packets and to properly reproduce silence intervals during Playout.

Abstract: A space and power efficient digitally controlled, all solid state, DC to AC converter powered by low voltage DC, typically found in logic circuits, that generate a high voltage low frequency AC output with a low slew rate waveform, suitable for activation of an electro-mechanical bell or electronic ringer in a telephone. The present invention is particularly suited for application in small, wireless terminals used to provide telephone services via satellite or terrestrial radio to single users or a small number of users as found in a PBX. The present invention is also particularly suited for battery or solar powered equipment where power efficiency is of significant value.

Abstract: The Real-Time Embedded Software Repository Apparatus fully characterizes, evaluates, and reuses real-time embedded software that is placed or stored in a repository database. The Repository System comprises at least one Repository Client and at least one Repository Server and utilizes simulation and translational techniques to allow Real Time Embedded Software (RTES) to be re-used, played, and evaluated on various desktop development environments or target operating environments. The Repository System organizes and processes Repository files as Repository Units which may comprise Software Source Files and Test Software. Repository Units also contain Attachments that provide current and historic information to static files that are stored in the Repository. The Repository Units are further characterized using analysis tools (software analysis) which allow the user to associate fixed and user defined Attributes to the RTES.

Abstract: The present invention provides network management of a network or multiple networks, using a Web client, and including multimedia and hypermedia capability. The present invention provides a unified, remote, graphical, transparent interface for Web users, working at a Web client, to a variety of managed networks. The present invention receives requests from a Web client forwarded by a Web server and interacts with the managed networks and their associated objects to obtain information. The present invention then converts this information in real time to hypermedia document format in HTTP and HTML, and transmits this information to the Web client via the Web server, appearing to the client as information in a Web file. This permits a Web user to manage multiple networks and access multiple networks via a single Web client, thus providing a unification of the management interface for dissimilar managed networks, and devices.

Abstract: A codeword forcing technique is applied which provides gradual degradation of an audio output during fading such that analog degradation in a fading signal environment is simulated.

Abstract: A method of passing tones transparently over narrowband channels without having to detect the tones at the transmit side is described. This method requires neither separate handling of tones for the transmission purpose, nor prior knowledge of the characteristics of the signaling tones used. It is a relatively general method that can be applied to systems using a variety of speech coding techniques utilizing a frame structure.
