  • Apparatus and method for interfacing between a communications channel and a processor for data transmission and reception
    Patent number: 5802153
    Abstract: An apparatus (101) and method for interfacing between a processor (103) and a communications channel (105), the processor operable in data terminal equipment (102) such as a computer having a communications application program, to provide for data transmission and reception over a communications channel (105), utilizing the computer processor without additional or redundant microprocessor or digital signal processor components. The apparatus and method provide for data transfer between the interface apparatus (101 ) and the communications channel (105) at a first, determinate frequency corresponding to a specific data transmission rate. The apparatus and method provide for data transfer between the interface apparatus (101) and the processor (103) at a second, indeterminate frequency, and provides for interim data storage in memory (115) between data transmission (or data reception) and data processing, such as modulation and demodulation, by the computer processor (103).
    Type: Grant
    Filed: February 28, 1996
    Date of Patent: September 1, 1998
