摘要： The present invention presents a method of identifying faults in a DSL line using upstream and downstream attenuation measurements, which can be obtained directly from the DSLAM or CPE, thus requiring no specialist test equipment nor disrupting service. A downstream over upstream attenuation ratio is calculated for a line, with calculations repeated over a population of lines. The distribution of ratios, as well as upper and lower thresholds, is determined based on the population. A line is identified as being potentially faulty if it has an attenuation ratio above the upper threshold or below the lower threshold. Specifically, an attenuation ratio below the lower threshold is identified as having a high resistance joint fault (caused by an imperfect connection or corrosion at a joint in at least one of the pairs of a line), and a ratio above the upper threshold as a shunt (caused by degradation of the insulation between the pairs of a line, and often coupled with water ingress).

摘要翻译： 本发明提出了一种使用上行和下行衰减测量来识别DSL线路中的故障的方法，其可以直接从DSLAM或CPE获得，因此不需要专门的测试设备或中断服务。 对于一条线，计算下游超过上游衰减比，计算重复在一条线上。 比例的分布以及上限和下限是根据人口来确定的。 如果一条线具有高于上阈值或低于下阈值的衰减比，则线被识别为可能有故障。 具体地说，低于下阈值的衰减比被鉴定为具有高阻抗关节故障（由线对中的至少一对中的接头处的不完美连接或腐蚀引起）和高于上阈值的比率作为 分流（由线对之间的绝缘的降解引起，并且经常与水入口耦合）。

摘要： Method and arrangement in a telecommunication system for estimating frequency dependent resistance of a transmission line. Insertion loss per length unit of the transmission line at a first frequency is determined. Thereupon a first resistance per length unit based on the determined insertion loss per length unit of the transmission line is calculated. Effective resistance per length unit at a second frequency based on the calculated first resistance is calculated. The calculated effective resistance could be used when estimating the insertion loss for the second frequency and all frequencies of interest.
