  • Method and system for achieving improved data transmission through the public switched telephone network
    Patent number: 6285672
    Abstract: The present invention comprises a smart subscriber line interface card (SLIC). The SLIC of the present invention includes a first and a second switch. A data receiver is coupled to a first output of the first switch to receive a user output signal and is adapted to generate a data receiver output therefrom. An ADC (analog to digital converter) is coupled to a second output of the first switch to receive the user output signal and is adapted to generate an ADC output therefrom. A data transmitter is coupled to a first input of the second switch and is adapted to generate a data transmitter output from a received digital network signal and couple the data transmitter output to the first input of the second switch. A DAC (digital to analog converter) is coupled to a second input of the second switch and is adapted to generate a DAC output from the received digital network signal and couple the DAC output to the second input of the second switch.
