A modem system start-up routine is performed in an improved manner such that information related to the exchange of the operational capabilities of the modem devices is transmitted at a higher data rate than prior art systems. A transition protocol is utilized to enable the modem system to seamlessly shift operating modes during the start-up routine. An initial data rate is utilized to transmit initial capabilities exchange data near the beginning of the start-up routine. Next, an initial training procedure is conducted to train the receive modem for operation at an intermediate data rate. The exchange of operational capabilities occurs at this intermediate data rate. Eventually, the modem system shifts to the primary data rate utilized during the normal data transmission mode. A final training procedure is performed to tune the receive modem in a more precise manner in response to the primary data rate. The overall effect of the improved start-up routine is a reduction in the start-up latency time.
