Method and device for checking the connection of a positive supply voltage to a subscriber access line comprising a plurality of wires
Abstract:
According to the invention, a user connection cable (TAL) that is to be associated with a user connection circuit (SLIC) and is used for connecting at least one user (TN) to at least one communication network is verified regarding switching on of a positive distribution voltage in the strands (a, b). The user connection circuit (SLIC) is initially switched to the silent interval mode and a test impedance (I) is switched between the strands (a, b) of the user connection cable (TAL), whereupon the current (i) flowing across the strands (a, b) and the voltage (u) to ground of a strand (b) are measured. Advantageously, the measurements are taken via measuring devices disposed on the user connection subassembly (SLMA).
Abstract(Chinese):

根据本发明，关于与用户连接电路（SLIC）相关联并且用于将至少一个用户（TN）连接到至少一个通信网络的用户连接电缆（TAL）被验证关于 线（a，b）中的正分布电压。 用户连接电路（SLIC）最初切换到无声间隔模式，并且在用户连接电缆（TAL）的线束（a，b）之间切换测试阻抗（I），于是流过 测量股线（a，b）和股线（b）的接地电压（u）。 有利地，通过设置在用户连接子组件（SLMA）上的测量装置进行测量。
