Abstract
Official abstract text for this publication.
Methods and systems are provided for detection of noise ingress into a network. In an aspect, multiple access devices on the network are analyzed for noise ingress. In another aspect, using characterization data of components in the network and the detection of the noise at the access devices, the location of the noise ingress can be determined.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method comprising: detecting changes in post-equalization filter coefficients of each of a plurality of devices connected to a network; determining, for each of the plurality of devices, multiple possible attenuation levels of noise transmitted to that device from respective multiple possible ingress locations in the network; and identifying one of the multiple possible ingress locations as a location where ingress of the noise occurred based on…
