Title: Intelligent rate option determination method applied to ADSL transceiver

Abstract: A system and method that generates rate options for ADSL transceivers is described. The system and method dedicates discrete multitone symbol bandwidth to bearer channels based on a prioritization of the bearer channels. A rate option generator determines the number of bytes contained in discrete multitone symbols modulated by a modulator. The rate option generator also receives a prioritization of the bearer channels and allocates portions of the number of bytes contained in the discrete multitone symbol to the bearer channels based on the prioritization. In order of priority, each bearer channel is allocated its maximum allowed number of bytes so long as discrete multitone symbol bandwidth remains available. Also, as part of the discrete multitone symbol bandwidth allocation, a bearer channel is not allocated less than its allowed minimum number of bytes.
