Broken Binder Detection in DSL Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for detecting broken binders in DSL networks are ineffective for operators lacking detailed topology information, as they rely on accurate network documentation, which is often unavailable.
Innovation Solution
A method and device that identify transmission interruptions, determine virtual distances between telecommunication lines based on line data, cluster lines, and detect broken binders without requiring topology information, using connection entity identifiers, crosstalk cancellation data, and geographical positions to determine the likelihood of lines belonging to the same binder.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If topology information is used for broken binder detection, then detection accuracy is improved, but the method becomes useless for operators without accurate documentation
Solution Approach 1:
The patent introduces an intermediary approach by using available network data (line parameters, connection information) as a mediator to infer binder groupings without requiring direct topology information. This intermediary data enables detection accuracy while maintaining versatility across different operator contexts.
Solution Approach 2:
The patent creates a virtual representation or 'copy' of the network topology by analyzing patterns in available line data. This virtual topology model allows broken binder detection to function as if accurate documentation existed, without actually requiring it, thus resolving the contradiction between accuracy and adaptability.
2Measurement precision
If virtual distance calculation is performed for all line pairs, then cluster accuracy is improved, but computational complexity increases
Solution Approach 1:
The patent segments the computational task by dividing line pairs into groups based on preliminary criteria (such as geographic proximity or network segment). This segmentation reduces the total number of virtual distance calculations needed while maintaining cluster formation accuracy, as only relevant line pairs within each segment need detailed analysis.
Solution Approach 2:
The patent applies partial action by calculating virtual distances for only the most promising line pairs rather than all possible pairs. By using thresholds and filtering criteria, the system performs sufficient calculations to achieve accurate clustering without the excessive computational burden of exhaustive pairwise analysis.
