The core idea of this invention is that functionality is added to modems which allows them to renegotiate a higher data rate if the quality of the service improves, or a lower data rate if recurring errors would otherwise result in a dropped connection. Thus the invention provides a method by which modems are enabled to renegotiate the communication parameters, even after a session has been established, thus providing optimum throughput by adapting the transmission rate without the need to disconnect and attempt to reconnect at a different (hopefully higher) data rate.
