  • 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.

  • Method and system for achieving faster asymmetric data transmission through the public switched telephone network
    Patent number: 6002684
    Abstract: The present invention comprises a smart subscriber line interface card (SLIC). The SLIC of the present invention includes a switch coupled to a data transmitter, a DAC (digital to analog converter), and a controller circuit. The data transmitter is coupled to a first input of the 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 switch. The DAC is coupled to a second input of the 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 switch. The controller circuit is coupled to the switch and functions by configuring the switch for either efficient data transmission via the data transmitter, or conventional communication via the DAC.
