摘要： A communication apparatus and method includes a modem operable for connection to a telephone line. Further, under control of a graphical user interface program executable on a personal computer, various processing may be provided. For example, the apparatus and/or method may convert received voice signals from the local user into outgoing digital voice information and convert incoming digital voice information into voice signals, and further may compress the outgoing digital voice information into compressed outgoing digital voice information and decompress compressed incoming digital voice information into the incoming digital voice information. Yet further, processing circuitry may be operable to packetize the compressed outgoing digital voice information and provide outgoing voice packets based thereon (e.g., each of the outgoing voice packets including at least one header), and further may packetize outgoing data packets including outgoing digital data information (e.g., each of the outgoing data packets including at least one header). The processing circuitry may yet further be operable to combine the outgoing voice packets and the outgoing data packets to provide a stream of outgoing packets to the telephone line via the modem, and also receive a stream of incoming packets via the modem from the telephone line. The stream of incoming packets may include incoming data packets and incoming voice packets. Each of the incoming voice packets includes at least one header and each of the incoming data packets includes at least one header. The headers of the incoming voice packets and the incoming data packets include information used to route the incoming packets within the communication apparatus. Further, the processing circuitry may be operable to separate the stream of incoming packets to provide the incoming data packets and the incoming voice packets.

摘要： One aspect is a network system including a network sewer and a plurality of gateway hosts coupled to the network server and each including a sectorized antenna and defining a plurality of gateway areas. An overlapping gateway grid includes the plurality gateway areas, each gateway area including sectors. The network system includes a plurality of endpoints, each sending and receiving 10 communication signals to and from at least two gateway hosts, and each comprising an oscillator calibrated with a clocking frequency. The network server determines the location of a target endpoint by sending communication signals between two selected sectorized antennas and the target endpoint to determine one sector from each of the two selected sectorized antennas in which the target endpoint is located, 15 and by calculating the time-of-flight for the communication signal to travel between each of the selected sectorized antennas and the target endpoint.

摘要： A data multiplexing network is described which multiplexes a plurality of asynchronous data channels with an asynchronous data stream representing compressed voice signals and/or facsimile signals onto a single synchronous data packet stream. The single synchronous data packet stream is then transmitted by a high speed statistical multiplexer over a composite link to a second site using a modified high-level synchronous data link control protocol with an overlay of an advanced priority statistical multiplexing algorithm. The asynchronous data channels and the compressed voice channel and/or facsimile signals are demultiplexed and reconstructed for sending to other asynchronous computer terminals and to a standard telephone or facsimile analog port at the second site, respectively. PBX trunk interfaces are also provided to allow PBX's to share the composite link between sites. Communication between the first site by voice or facsimile and the second site is transparent to the users. The multiplexer efficiently allocated the bandwidth of the composite link by detecting silence periods in the voice signals and suppressing the sending of the voice information to preserve bandwidth. An advanced priority statistical multiplexer is also described which dynamically allocates composite link bandwidth to both time-sensitive and non-time-sensitive data to maximize data throughout efficiency and quality while simultaneously reducing multiplexer processing overhead

摘要： A personal communications system enables the operator to simultaneously transmit voice and data communication to a remote site. The personal communications system is equipped with two telephone line interfaces to allow connection between two remote sites. The connection between the first remote site and the local site may operate in a voice over data communications mode to simultaneously send compressed voice and data. A digital transmission protocol which is consistent with current packet standards is used to create an independent channel through use of a modified supervisory packet for negotiating communication parameters, including the speech compression algorithm, the speech compression ratio, the communication multiplex scheme, and other operations needed for control of remote hardware interfaces.

摘要： A personal communications system enables the operator to simultaneously transmit voice and data communication to a remote site. The personal communications system is equipped with two telephone line interfaces to allow connection over a communications link between two remote sites. The personal communications system incorporates advanced priority statistical multiplexing of non-time-critical data with time-critical data over the communications link to increase channel throughput without a reduction in quality of the time-critical data. The personal communications system may be networked in different topological configurations to enable conferencing in a variety of time-critical and non-time-critical communications.
