Method and apparatus for making a voice and/or data call over a single analog phone line using a multi-modal DCE

Image Number 7 for United States Patent #6298121.

An enhanced micro-controller having multiple operating modes is provided to an otherwise conventional data circuit terminating equipment (DCE). The enhanced micro-controller, responsive to local events as well as local and remote commands, controls the operation of the DCE in one of at least four modes, an idle mode, an analog voice mode, a digital data mode, and a simultaneous voice and data (SVD) mode. As a result of the improved manner in which the micro-controller operates the DCE, users employing the improved DCE may perform voice and data communication using only a single analog-loop telephone line and in a much more user friendly manner.
