Abstract
A system and method for improving communications, wherein Frequency Division Multiplexed (FDM) modems are communicatively coupled over a bi-directional channel. Bandwidth is apportioned to satisfy a desired downstream-to-upstream data rate ratio by measuring upstream and downstream channel parameters and determining a data rate ratio. The determined ratio is compared to the desired ratio, and if the determined ratio is less than the desired ratio, the bandwidth is adjusted, and the process repeats until the desired ratio is obtained.
