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. A controller circuit is coupled to the first switch and the second switch and functions by configuring the first and second switch for either efficient data transmission and reception via the data receiver and data transmitter, or conventional communication via the ADC and the DAC.
