Publication number: 20030223461Abstract: 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.Type: ApplicationFiled: January 17, 2003Publication date: December 4, 2003Applicant: Multi-Tech Systems, Inc.Inventors: Raghu Sharma, Jeffrey P. Davis, Timothy D. Gunn, Ping Li, Sidhartha Maitra, Ashish Thanawala, Steve Young

Publication number: 20030223407Abstract: 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: ApplicationFiled: January 29, 2003Publication date: December 4, 2003Applicant: Multi-Tech Systems, Inc.Inventors: Raghu Sharma, Jeffrey P.

Patent number: 5790532Abstract: A personal communications system is described which includes components of software and hardware operating in conjunction with a personal computer. The user interface control software operates on a personal computer, preferably within the Microsoft Windows.RTM. environment. The software control system communicates with hardware components linked to the software through the personal computer serial communications port. The hardware components include telephone communication equipment, digital signal processors, and hardware to enable voice, fax and data communication with a remote site connected through a standard telephone line. The functions of the hardware components are controlled by control software operating within the hardware component and from the software components operating within the personal computer.Type: GrantFiled: September 14, 1995Date of Patent: August 4, 1998Assignee: Multi-Tech Systems, Inc.Inventors: Raghu Sharma, Jeffrey P. Davis, Timothy D. Gunn, Ping Li, Sidhartha Maitra, Ashish Thanawala, Steve Young

Patent number: 5592586Abstract: A system for performing voice compression which includes, a conversion means for converting analog voice signals into discrete samples of digital voice data and collecting the discrete samples into segments, with a means for dividing the segments into subsegments and for producing therefrom a current voice subsegment. A pitch prediction means is used for determining the long term predicted gain of the current voice subsegment by comparing the current voice subsegment to reconstructed voice samples to produce a pitch predictor gain and a lag component and a pitch filter means is used for pitch filtering the current voice subsegment based on the pitch predictor gain and the lag component which then produces long term residual samples.Type: GrantFiled: August 11, 1994Date of Patent: January 7, 1997Assignee: Multi-Tech Systems, Inc.Inventors: Sidhartha Maitra, Ashish Thanawala, Steve Young
