Abstract:
A method for training a modem, comprising:selecting a transmission rate from one of a plurality of bauds, each baud identifying at least one transmission rate; attempting to train the modem at the transmission rate; measuring a signal quality after the modem trains; accessing a table of acceptable signal qualities, the table corresponding to the baud of the transmission rate; comparing the measured signal quality to at least one acceptable signal quality identified by a provisioned margin in the table to determine if the measured signal quality is acceptable; wherein the transmission rate comprises a first transmission rate in a downstream direction, further comprising: selecting a second transmission rate from one of a second plurality of bauds, each of the second plurality of bauds identifying at least one transmission rate, the second transmission rate comprising a transmission rate in an upstream direction; and attempting to train the modem at the first and second transmission rates.
