Patent number: 7082106Abstract: 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.

Patent number: 7082141Abstract: 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.Type: GrantFiled: January 29, 2003Date of Patent: July 25, 2006Assignee: Multi-Tech Systems, Inc.Inventors: Raghu Sharma, Jeffrey P.

Patent number: 6359894Abstract: 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.Type: GrantFiled: December 23, 1999Date of Patent: March 19, 2002Assignee: Multi-Tech Systems, Inc.Inventors: Kevin Hong, Bhat V Damodar, Sundararajan Narasimhan, Dale W.

Patent number: 5764628Abstract: 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.Type: GrantFiled: October 15, 1996Date of Patent: June 9, 1998Assignee: Muti-Tech Systemns, Inc.Inventors: Jeffrey P.
