摘要： To test at least one subscriber line that can be connected to a line unit, at least one test signal is emitted along the subscriber line, when the latter is not actively connected, and at least one resultant first echo signal is received, recorded and stored. In the short-circuited or open condition of the subscriber line, the test signal or signals is/are emitted via said line and at least one resultant second echo signal is stored. If an error occurs, the test signal or signals is/are emitted along the subscriber line and at least one resultant error echo signal is recorded, said error echo signal being compared with the first and/or second echo signal or signals. The advantage of the invention is that the location of an interruption in the subscriber line can be determined locally without the use of complex measuring devices.
摘要翻译：为了测试至少一个可以连接到线路单元的用户线路，当用户线路不被主动连接时，沿用户线路发射至少一个测试信号，并且接收，记录和存储至少一个所得到的第一回波信号。在用户线的短路或开路条件下，经由所述线路发射测试信号或信号，并存储至少一个所得到的第二回波信号。如果发生错误，则沿用户线发射测试信号或信号，并记录至少一个合成误差回波信号，所述误差回波信号与第一和/或第二回波信号进行比较。本发明的优点在于，可以在本地确定用户线路中的中断位置，而无需使用复杂的测量设备。
