After you have updated the modem you may notice that the connection speed that is reported when you first establish a connection may be lower than it was prior to the upgrade, however the modem throughput will be at least as good and often better than before the upgrade. Throughput is the measure of how quickly a certain amount of data is transferred from one modem to another. It is important to remember that the connection speed that is reported is only the initial connection speed. The modems will adjust their communications speed as line conditions require. A faster connection speed does not necessarily indicate a higher throughput, factors like resending data due to noise on the phone lines will lower overall throughput.
