ABSTRACT:
A technique is provided for an electrical device to automatically detect one of a plurality of interface standards to operate in accordance with. More particularly, a direct access arrangement (DAA) for communicating with telephone lines is provided for utilization with modem communications over a phone line. The DAA may be configured to automatically detect and operate in accordance with a plurality of interface standards for communications to a host system. For example, the DAA may detect that communications are to be provided in accordance with the AC-97 interface standard or the Azalia interface standard. In one embodiment, a clock signal may be monitored to determine the proper interface mode. In another embodiment, the automatic detection of the proper interface mode may be accomplished by monitoring the data presented to the DAA through the interface standard.
