Embodiment Construction

[0032] The invention allows efficient identification of groups of lines that respond coherently to changes in their physical conditions without interrupting their service. This thus allows the operator to identify clusters of strongly coupled lines within a bundle. Assuming the quality of the physical link on the line comprising the packet, for example as figure 1 This information is useful when a damaged (e.g., wet) binder is identified, when there is a strong interferer in the vicinity of a given binder, or when there is a non-ideal connection at the binder interface. Based on this identification, detailed diagnostic analysis or optimization features can be selectively initiated on the affected lines, or on-site intervention can be established at the bundler level if required.

[0033] It is an object of embodiments of the present invention to identify line clusters that exhibit similar trends in the evolution of some physical properties over time.

Abstract

The invention provides a method and a device for clustering lines of a wireline network in a number of virtual binders, comprising obtaining a noise value samples pertaining to different lines of the wireline network at substantially coinciding sampling moments, detecting corresponding features in these series, determining degrees of correlation between these features, and assigning the lines to one or more virtual binders on the basis of their mutual degrees of correlation.

Description

technical field [0001] The present invention relates to the detection of physical defects in the lines of cable networks, more particularly to xDSL based access networks. Accordingly, the present invention provides a method for clustering lines of a wired network into a plurality of virtual blinders, a device for performing the method, and a system including the device and an access node. Background technique [0002] Triple play technology allows the provision of services requiring very high performance in terms of bit rate and stability. When wired infrastructure is used for data transmission, as in the case of xDSL based access networks, achieving the required performance level can become challenging, especially for longer loops. Furthermore, in the presence of physical defects, the quality of service degrades dramatically and the end user's quality of experience can become unacceptably low. In the case of IP TV, this low quality of experience can manifest itself in the...
