The system presented in this paper improves the performance of data communication through telephone switching networks. A time assignment method is used to interpolate voices into a data (modem) signal stream. On the receiving section, the on-line identification and dispatching is based on the differences of these signals.Having made some improvements, the new version of such a system can transmit data streams with a bit rate of 300, 600, or 1200 bit/s, and with a higher reliability of...
