Embodiment Construction

[0039] Embodiments of the present invention can be designed to work primarily with standard VDSL and G.fast network equipment, where the operating frequency range for DSL service has significant overlap with many standard PLT systems, but this approach is also applicable to other DSL technologies Or run through non-standard network test equipment or modem hardware applications.

[0040] Another potential advantage is that the method can identify the overall performance of the DSL link, rather than the performance of the in-home network or the entire IP session.

[0041]By analyzing the aggregated usage patterns, a PLTI detector according to one embodiment may be able to derive DSL service impact directly from the diagnostic results, thereby providing not only detection but also a clear understanding of the measures used to mitigate PLTI impact on subscriber service Next steps required.

[0042] Advantageously, the method according to the preferred embodiment may use Physical ...

Abstract

The present invention relates to methods for determining the presence and reducing disturbances in power line transmissions. Interference on a DSL (Digital Subscriber Line) system can be identified by collecting modem data and determining over multiple time intervals whether the line is carrying traffic and / or whether there are errors on the line. The presence of interference can be inferred from the correlation of traffic data and error data.

Description

technical field [0001] The present invention relates to identifying interference to Digital Subscriber Line (DSL) services such as ADSL, VDSL or G.fast, hereafter referred to as DSL or xDSL. Background technique [0002] It is well known to use legacy (or newly installed) copper wire originally used for analog telephone service for the last mile transmission of broadband or DSL signals to and from the premises. Such signals are susceptible to various types of noise and interference, and the modems at each end negotiate the transmission rate based on the signal-to-noise ratio, and can resynchronize if transmission conditions change. Noise can come from various sources, including crosstalk between adjacent cables to adjacent premises, external noise, and noise generated by electrical equipment within the premises, and can vary over time. By its very nature, the source of this noise is often unknown and cannot be reliably predicted. [0003] It is understood that in some prem...
