  • Patent number: 5905794
    Abstract: An interface for modems 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. A line reversal detector is incorporated to signal when the caller identification information is available for reception. A two stage detection system is used to eliminate false signaling of line reversals and discriminate line reversals from ringing and other noise signals.

  • Patent number: 5864560
    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 second remote site may operate in an analog voice mode, a digital data communications mode, and a voice over data communications mode. A switch between analog voice mode and digital data communications mode and analog voice mode and voice over data communications mode is performed using switching tones, including calling tones, answer tones, and DTMF tones. Hardware and software switches are also used to program the modems in the personal communication systems for originating and answering modes.

  • Patent number: 5617423
    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.

  • Patent number: 5546395
    Abstract: 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.
