In a simultaneous voice and data communications system comprising two modems, an autorate feature is implemented in one illustrative method by adding a silence detector to the receiver circuitry of at least one of the modems in such a way that noise statistics for the communications channel are only accumulated during intervals of silence. If the resulting noise statistics exceed a predetermined threshold, i.e., the communications channel is too noisy, the receiving modem negotiates a lower data rate with the transmitting modem. In another illustrative method, the transmitting modem provides a signal, which represents an interval of silence, to the receiving modem. Upon receipt of the signal, the receiving modem accumulates error statistics in order to determine if the communications channel is too noisy.
