Abstract
An apparatus for reducing modem command and status latency within a direct access arrangement (DAA) circuit is disclosed. The DAA circuit includes a serial audio interface for providing communications between the DAA circuit and the host computer system. The serial audio interface can operate under multiple serial communication interface standards, such as the AC '97 standard and the HD Audio standard. The DAA circuit also includes means for configuring the serial audio interface to transmit and receive modem samples at an audio sample rate higher than a modem sample rate of the modem samples and at a predetermined bit size that is wider than a bit size of the modem samples. The additional bits other than the modem samples are utilized to indicate command and status information associated with the DAA circuit or a telephone line such that modem command and status latency on the serial audio interface within the DAA circuit can be reduced.
