Abstract

An enhanced micro-controller having multiple operating modes, including an idle mode, an analog voice mode, a digital data mode, and a simultaneous voice and data mode, and control logic for establishing multiple logical connections and voice as well as data transmission protocols over these logical connections with another DCE, when switching from the analog voice mode to the simultaneous voice and data mode, is provided to a DCE designed to support multi-modal voice and/or data calls over a single analog-loop telephone line. In one embodiment, the establishment of the voice transmission protocol includes joint negotiation of the voice compression/decompression algorithm to be used by the mode transition initiating and responding DCEs.
