Abstract
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.
Claims23
A method comprising:
- detecting a level of noise received at each of a plurality of devices connected to a network;
- determining, attenuation of a noise source received at each of the access devices for multiple possible locations of noise ingress in the network;
- and
- identifying, one of the multiple possible locations as a location where ingress of the noise source occurred based on the detected level of noise received at each of the plurality of devices and the determined attenuation of the noise source received at each of the plurality of devices for the multiple possible locations.

A method comprising:
- receiving multiple iterations of network characterization data, over respective multiple iterations of time, from each of a plurality of devices connected to a network;
- detecting, for each of the plurality of devices, a difference between two of the iterations of the network characterization data;
- and
- identifying a location of ingress into the network of a noise source based on the detected differences for each of the plurality of devices and based on locations of the devices in the network.
1 more element
One or more memory storing machine-readable instructions that when executed by one or more processors cause an apparatus to:
- retrieve signaling characteristics of one or more network components in a network;
- identify signal paths from multiple possible locations of ingress of a noise source to each of a plurality of devices connected to the network;
- associate the retrieved signaling characteristics of the one or more network components to the identified signaling paths;
- and
- determine attenuation of the noise source at each of the devices for the multiple possible locations of ingress in the network based on the associating;
- and
- store in the one or more memory the determined attenuation of the noise source at each of the devices for the multiple possible locations of ingress.
