Abstract
A single board multiple option card for expanding the versatility of a host computer includes an onboard microprocessor, a digital signal processor and a switched memory device. The switched memory is accessible by the onboard microprocessor and the digital signal processor under the control of the onboard microprocessor. The card further includes an analog signal interface having a plurality of switches, the positions of which are controlled by the onboard microprocessor. As a result, multiple options are provided by varying the positions of the switches. Typically, such options may include: "Invisible Keyboard"; "Voice Command Over Telephone Lines"; "Voice Store and Forward Over the Telephone"; "Voice Record and Playback"; and "Hands-free Telephone".
