An apparatus includes a housing, an interface, a processor and a memory. The interface is affixed to the housing and is configured for coupling to a cellular wireless network. The processor is affixed to the housing and is coupled to the interface. The memory is affixed to the housing and is coupled to the processor. The memory is configured to store a set of instructions for causing the processor to receive a first message using the interface and, in response thereto, for causing the processor to broadcast a second message using the cellular wireless network and using the interface, the second message having a transmission parameter determined by the first message and wherein the second message is compatible with a messaging service protocol.

An improved telecommunication device for simultaneous and independent communication of analog signals and digital data is disclosed. Processing of analog signals enables functions including, for example, message saver, speaker phone, caller identification and fax. Processing of digital data enables functions, including, for example, DSL modem communications, digital voice communications, video communications, and voice-over-data communications. The disclosed system may operate independently or coupled to one or more computers.

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.

Remote access and configuration of a digital subscriber line (DSL) device using a telephone line. From a remote location, an operator can access the DSL device and receive data, including an operational parameter regarding the device, and upload an operational parameter or firmware, and thus, establish the operational configuration of the device. Also from a remote location, an operator can troubleshoot and provide technical support functions for the device.

An interactive computer program generates a composite dot matrix representation of secondary structure elements from a set of functionally related oligonucleotides. The composite image facilitates visual detection of conserved secondary structure motifs with similar sequence sets. The complete pattern displaying all possible base pairings can be readily pruned with two progressive filters to provide the user with a simplified figure displaying only the most stable and conserved regions. Additional simplification of the structure matrix image can be achieved by eliminating mutually exclusive structures. Alignment editing provided within the program facilitates refinement of the consensus secondary structure.

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.

The present invention includes software and hardware components to enable digital data communication over standard telephone lines. The present invention converts analog voice signals to digital data, compresses that data and places the compressed speech data into packets for transfer over the telephone lines to a remote site. A voice control digital signal processor (DSP) operates to use one of a plurality of speech compression algorithms which produce a scaleable amount of compression. The rate of compression is inversely proportional to the quality of the speech the compression algorithm is able to reproduce. The higher the compression, the lower the reproduction quality. The selection of the rate of compression is dependant on such factors as the speed or data bandwidth on the communications connection between the two sites, the data demand between the sites and amount of silence detected in the speech signal. The voice compression rate is dynamically changed as the aforementioned factors change. A negotiation handshake protocol is described which enables the two sites to negotiate the compression rate based on such factors.

A device includes an analog front end, a converter processor, and a network port. The analog front end includes a first modem configured to couple to a first line of a modem bank and includes a second modem configured to couple to a second line of the modem bank. The modem bank is configured to couple to a host processor. The first modem is operable independent of the second modem. The converter processor is coupled to the analog front end. The network port is coupled to the converter processor and configured to communicate with a network. The converter processor is configured to execute instructions to exchange data between the network and the modem bank.
摘要:
An interface for personal communications systems is described which provides rapid identification of a caller and limited access based on a variety of parameters obtained from caller identification information encoded by the telephone company. The incoming telephone call information is compared to a preprogrammed access matrix to determine if the caller is authorized to access the personal communications system connected to the interface. A telephone call screening method and apparatus which incorporates the encoded caller identification is also described.
