摘要： A simultaneous voice and data modem (100) coordinates the storage of voice messages and data messages on an audio answering machine (25) and a personal computer (10), respectively. This allows the called party (User 1) to subsequently retrieve, via the simultaneous voice and data modem (100), both a voice message and an associated data message, i.e., a multimedia message, where the called party listens to the voice message while viewing the data message. The called party can retrieve the multimedia message either locally or from a remote location.

摘要： A multi-media modem is used to provide a security access arrangement that identifies a calling party to a computer system. In particular, a multi-media modem couples both an analog channel and a data channel to the computer system. The analog channel conveys the calling party's identification information, while the data channel conveys a data signal from the calling party. The computer system verifies the calling party's identification information communicated over the analog channel and, if the verification is successful, immediately establishes, or continues, data communications with the calling party over the data channel.

摘要： The present invention relates to an apparatus and method for controlling voice and data answering machines. The apparatus is comprised of a first port for coupling to a data terminal, a second port for coupling to an audio answering machine and a third port for coupling to a communications channel for receiving an audio message and a data message. A unit is present for providing a pair of message identification fields, one field associated with the received audio message for storage on the audio answering machine and the remaining field associated with the received data message for storage on the data terminal. The method, that is in fact a method of sorting a message is comprised of the steps of receiving a first message that represents information conveyed in a first media, receiving a second message that represents information conveyed in a second media and creating a pair of fields. Each field includes a message identification number, where one field is associated with the first message and the remaining field is associated with the second message. Finally the method includes storing each field and the respective message on separate storage devices.

摘要： A method and apparatus for control of concurrent communication of analog information and digital information. In general terms, when the communication channel is viewed as a multi-dimensional space, the digital information signal is divided into symbols, and the symbols are mapped onto the signal space with a preset distance between them. The analog signal, generally limited in magnitude to less than the distance separating the symbols, is converted to component signals and added (i.e., vector addition) to the symbols. The sum signal is then transmitted to the receiver where the symbols are detected and subtracted from the received signal to yield the analog signal components. The transmitted analog signal is recreated from those components. Both half-duplex and full-duplex operation is available in accordance with this invention. The illustrative embodiment includes control means that is sensitive to input signals applied to the modem disclosed herein. To wit, the control is sensitive to signals from the analog port, signals from the digital port, and signals from the port that carries the combined digital and analog signals. Operation of the near-end modem is controlled as well as operation of the far-end modem.

摘要： A number of arrangements and methods that achieve concurrent communication of analog information and digital information. In general terms, when the communication channel is viewed as a multi-dimensional space, the digital information signal is divided into symbols, and the symbols are mapped onto the signal space with a preset distance between them. The analog signal, generally limited in magnitude to less than the distance separating the symbols, is converted to component signals and added (i.e., vector addition) to the symbols. The sum signal is then transmitted to the receiver where the symbols are detected and subtracted from the received signal to yield the analog signal components. The transmitted analog signal is recreated from those components. Arrangements utilizing the above principles are applications where systems that include a digital port can benefit from an analog communication channel, and conversely, where systems that include an analog port can benefit from a digital communication channel.
