1. A method of enhancing upstream performance in a cable network, the method comprising:
- measuring performance of an upstream channel at a first data signaling rate;
determining whether said upstream channel supports a second data signaling rate based on said performance, said second data signaling rate being a higher rate than said first data signaling rate; and
selectively transitioning an active channel to said second data signaling rate based on a determination of whether said active channel supports the second data signaling rate, wherein the determination of whether said active channel supports the second data signaling rate is made based on said determination of whether said upstream channel supports the second data signaling rate and said upstream channel is different from the active channel and is representative of the active channel in the determination of whether said active channel supports the second data signaling rate.

Abstract
The present methods and systems provide spectrum management for enhancing upstream performance for cable networks. According to one embodiment, a method of enhancing upstream performance in a cable network includes the steps of measuring performance of an upstream channel at a first data signaling rate; determining whether the upstream channel supports a second data signaling rate based on the performance; and selectively transitioning to the second data signaling rate based on said determination. The second data signaling rate is a higher rate than the first data signaling rate.
