Patent ID: 7649929

Claim:
A method for configuring a direct access arrangement (DAA) circuit, wherein said DAA circuit is capable of coupling a host computer system to a telephone line while providing isolation between said host computer system and said telephone line, said method comprising: providing a programmable serial audio interface within said DAA circuit, wherein said serial audio interface allows for communications between said DAA circuit and said host computer system, wherein said programmable serial audio interface is capable of operating under a plurality of serial communication interface standards; and configuring said programmable serial audio interface to transmit and receive modem samples at an audio sample rate higher than a modem sample rate of said modem samples and at a predetermined bit size that is wider than a bit size of said modem samples; wherein said programmable serial audio interface is further configured for a sample width of 24 bits, such that M least significant bits (LSBs) of said 24 bits utilized to handle said modem sample data, and N most significant bits (MSBs) of said 24 bits utilized to indicate command and status information associated with said DAA circuit or said telephone line, where M and N are integers and where M is greater than N, wherein said command information is utilized for a sending modem and said status information is utilized for a receiving modem.
