Benefits of technology

The present invention is about a method and device for detecting and characterizing noise in a communication system, such as DSL. It includes a noise analysis engine that can classify different types of noise and track them in real-time, providing visibility into the changing noise environment in a customer's premises. The invention also uses noise signatures to identify and timing information about specific noise sources. Additionally, it includes a wiring analysis engine that detects and classifies wiring events that may affect the communication system. Overall, the invention helps to improve the performance and reliability of communication systems by identifying and managing noise sources in real-time.

Problems solved by technology

In a digital subscriber line (DSL) deployment, stationary and impulsive, noises are generated within the home environment, which impact the reliability of the wide area network (WAN) interface of a residential device delivering network services such as IPTV.

[0141 Data Records

[0142]Below are examples of output data records produced for various types (permanent, intermittent and evolving) of narrowband, wideband and impulsive noise sources according to embodiments of a noise analysis engine of the invention.

[0143]Continuous narrowband disturbers can be permanent, intermittent and evolving.

[0144]Typical permanent narrowband disturbers are for example AM radio transmitters. Continuous pulsed noise may also generate narrowband interference when the noise source is permanent. To distinguish AM radios and CM NBI, a possible discrimination factor exists in the fact that AM transmitters operate at known frequencies in any geographical region. An example objective of the logging is to monitor daily / nightly coupling variation (e.g. related to weather) of AM radios and assess how they impact the capacity of the user. The data logging output can be part of a 15 minute record with the number of continuous NBI disturbers and for each NBI, a vector of...

example implementation

[0173 of Noise Analysis Engine

[0174]Having described a generic noise analysis engine and its potential application in a DSL communication system, an example implementation of noise analysis engine in a DSL modem according to embodiments of the invention will now be provided.

[0175]In embodiments, a noise analysis engine according to the invention is implemented by supplementing a conventional DSL modem with noise monitoring functionality such as a SmartCPE diagnostics suite such as that provided by Ikanos Communications, Inc. of Fremont, Calif., as adapted by the present invention. Those skilled in the art will understand how to implement the noise analysis engine of the present invention by adapting software / firmware of these and other conventional DSL diagnostics programs after being taught by the present disclosure.

[0176]As shown in FIG. 4, a noise analysis engine 402 according to these embodiments of the invention includes two distinct analysis engines: line noise analysis engine...

Abstract

The present invention generally relates to a method and apparatus for effectively detecting and characterizing noise and other events affecting a communications system such as digital subscriber lines (DSL). According to certain aspects, the invention includes a noise analysis engine that is embedded in customer premises equipment that classifies noise sources according to their specific characteristics and tracks each noise source in a dynamic manner, in such a way as to provide visibility to the changing noise environment within the customer premises and / or report this environment to a remote entity.
