摘要
通过近几年的发展建设 ,在电力通信网中 ,PDH、SDH、ATM等数字通信技术已大量使用。对数字通信设备进行维护 ,必须采用先进的测试仪器仪表对故障进行准确定位 ,以尽快恢复通信电路 ,确保电力通信的快速、畅通。在设备的维护中 ,不仅要掌握设备的工作原理 ,熟悉信号的流程 ,更要掌握测试仪表的各种告警指示的含义 ,才能对故障进行准确定位。
With the developing and construction in these years,the power communication system has been formed its initial scale,the communication technology such as PDH,SDH and ATM etc.are widely used. In order to maintain these digital communication devices,we must use the advanced measure instrument to find the fault precisely,and resume the communication as soon as possible.In the maintenance of devices,not only we must know the principle of devices and have acquaintance with the flow of signal,but also we must know all kinds of the alarm indication on the measure instrument,so we can find the fault precisely. This paper presents the function of data tester,and the application of data tester.
