ABSTRACT:
The present invention pertains to a detection and switching circuit for processing and then routing signals between various devices (e.g., modem, telephone, speaker-phone, external or on-board speakers, microphone, etc.) coupled to a computer system. First, a user plugs the desired devices to the computer system. Next, the user selects amongst several different modes of operation. The circuit monitors the status of these various devices and the status of the incoming signals on the phone line. The resident software then processes the signals (e.g., analog audio signals or digital data signals) into the particular formats corresponding to these particular devices. Finally, the switches are set to route the signals to the appropriate devices. The processing and switching steps are performed automatically in accordance with the particular mode that the user has selected.
