  • Patent number: 7227933
    Abstract: 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.

  • Patent number: 7092406
    Abstract: A communication apparatus and method includes a modem operable for connection to a telephone line, a voice receiving interface apparatus for use in receiving voice signals from a local user, and a voice conveying interface apparatus for use in conveying voice signals to the local user. Further, processing circuitry, operable under control of a graphical user interface program executable on a personal computer, may be, for example, operable to convert received voice signals from the local user via the voice receiving interface apparatus into outgoing digital voice information, compress the outgoing digital voice information into compressed outgoing digital voice information, and packetize the compressed outgoing digital voice information and provide outgoing packets based thereon. Each of the outgoing packets includes at least one header.

  • Patent number: 7082106
    Abstract: Outgoing multi-media data components are provided in a communication system and method implemented under control of a user interface program. Each of the outgoing multi-media data components includes one or more types of information (e.g., textual information, graphical information, and audio information). Two or more outgoing multi-media data components are combined under control of a local user via input to the user interface program resulting in combined outgoing multi-media mail. At least one of the two or more outgoing multi-media data components is of a type of information different than another of the two or more outgoing multi-media data components. The combined outgoing multi-media mail is provided for communication to a remote location.

  • Patent number: 7082141
    Abstract: 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.

  • Patent number: 6359894
    Abstract: A remote communications server system enables multiple remote users simultaneous access to a network. The system connects a plurality of on-line sessions across multiple communication lines to the network. A unique combination of multiple buses, multiple processors, and a segmented design creates a distributed processing communications system having high throughput without the stability problems associated with gigabit bus speeds. Furthermore, the system supports a mixture of communication links and allows the substitution of one service type for another without affecting the remaining communication links. The system is scalable in that segments can be added as needed and the number of lines handled by a segment can be increased.

  • Patent number: 5764628
    Abstract: 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. The connection between the local site and a second site is a voice only connection allowing the first remote site to talk to the second remote site without breaking the data communication connection between the first site and the local site. The second remote site may be a public telephone network. The communication between the first remote site and the second remote site through the local site may also be a data communication connection, or it may also be a voice over data communication connection.

  • Patent number: 5680553
    Abstract: A method for the high-speed transfer of data between an IBM compatible personal computer (PC) and a bus device. A DMA controller is placed on the bus device to by-pass the PC's DMA controller. High-level terminate and stay resident software on the PC uses a combination of the DMA controller on the bus device and low level DMA controller routines to transfer the data between the PC and the bus device.
