| 1 | Method and apparatus for automatically converting from an analog voice mode to a simultaneous voice and data mode for a multi-modal call over a telephone line | US265314 | 1994-06-24 | US5606599A | 1997-02-25 | Barry O'Mahony; Narjala Bhasker |
| 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. | ||||||

| A system (10) and method (40) are provided permitting cookie files to be used with telephonic customer premises equipment (CPE) (12). The caller CPE (12) can be an intelligent telephone adapted to generate, store, transmit and receive cookie files. The cookie files can include information tokens describing a caller profile. The CPE (12) can provide a template cookie file upon request from a called party during a conversation between the caller and called party. The template file can then be transmitted to the called party and modified. The modified cookie file can then be returned to the caller CPE (12) for future use during subsequent calls to the called party. The cookie file can reduce the processing time of calls placed to automated dial-up service centers and also reduces its computer resources required by the service system. | ||||||
