US Patent:

20030223407, Dec 4, 2003

Filed:

Jan 29, 2003

Appl. No.:

10/353901

Inventors:

Raghu Sharma - North Oaks MN, US
Jeffrey Davis - Ham Lake MN, US
Timothy Gunn - Mounds View MN, US
Ping Li - New Brighton MN, US
Sidhartha Maitra - Saratoga CA, US
Ashish Thanawala - Saratoga CA, US

International Classification:

H04L012/66
H04L012/28
H04L012/56

US Classification:

370/352000, 370/401000

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., 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.

US Patent:

20030223461, Dec 4, 2003

Filed:

Jan 17, 2003

Appl. No.:

10/347024

Inventors:

Assignee:

Multi-Tech Systems, Inc. - Mounds View MN

International Classification:

H04J001/02

US Classification:

370/493000

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. The processing circuitry may further be operable to provide the outgoing packets to the telephone line using the modem, and receive incoming packets including compressed incoming digital voice information from the telephone line using the modem. Each of the incoming packets includes at least one header; the at least one header includes information used to route the incoming packets within the communication apparatus. Yet further, the processing circuitry may be operable to decompress compressed incoming digital voice information and convert decompressed incoming digital voice information into voice signals for conveyance to the local user via the voice conveying interface apparatus.

US Patent:

55747256, Nov 12, 1996

Filed:

Aug 11, 1994

Appl. No.:

8/289295

Inventors:

Raghu Sharma - North Oaks MN
Jeffrey P. Davis - Ham Lake MN
Timothy D. Gunn - Mounds View MN
Ping Li - New Brighton MN

Assignee:

Multi-Tech Systems, Inc. - Mounds View MN

International Classification:

H04J 312

US Classification:

370 79

Abstract:

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. The major functions of the system are a telephone function, a voice mail function, a fax manager function, a multi-media mail function, a show and tell function, a terminal function and an address book function. The telephone function allows the present system to operate, from the users perspective, as a conventional telephone using either hands-free, headset or handset operation.

Ringdown And Ringback Signalling For A Computer-Based Multifunction Personal Communications System

View page

US Patent:

55352049, Jul 9, 1996

Filed:

Oct 25, 1993

Appl. No.:

8/142807

Inventors:

Ping Li - New Brighton MN

Assignee:

Multi-Tech Systems, Inc. - Mounds View MN

International Classification:

H04J 312

US Classification:

370 76

Abstract:

The voice over data component of a personal communications system enables the operator to simultaneously transmit voice and data communication to a remote site. This voice over data function dynamically allocates data bandwidth over the telephone line depending on the demands of the voice grade digitized signal. The user may enter voice over data mode from a data transfer mode by lifting the handset of the telephone connected to the modem. The off-hook condition is sensed and software sends a supervisory packet to the remote site to invoke voice-over-data mode. The remote telephone will simulate a ring to alert the remote user, and the local telephone will simulate a ringback to inform the caller that the remote unit is responding.

US Patent:

56174233, Apr 1, 1997

Filed:

Jul 7, 1994

Appl. No.:

8/271496

Inventors:

Ping Li - New Brighton MN
Timothy D. Gunn - Mounds View MN
Jeffrey P. Davis - Ham Lake MN

Assignee:

Multi-Tech Systems, Inc. - Mounds View MN

International Classification:

H04J 312
H04L 1256

US Classification:

370426

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. 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.

US Patent:

53012747, Apr 5, 1994

Filed:

Aug 19, 1991

Appl. No.:

7/746857

Inventors:

Ping Li - New Brighton MN

Assignee:

Multi-Tech Systems, Inc. - Minneapolis MN

International Classification:

H04B 1404
H04M 1106
G06F 300
G06F 1300

US Classification:

395250

Abstract:

A method for dynamically changing the polling process of a single microprocessor within a modem. An additional step is added into the main polling loop that checks the amount of data in the transmit and receive buffers. If one buffer is empty, additional polling cycles are performed to service the other buffer. The number of additional cycles is dependent on how full the buffer is. If both buffers contain data, no change is made in the polling process and both are serviced with equal priority.
