摘要
针对现有电话网用户线电缆的高速率数字传输衰减特性和非加感市话电缆各项电参数的精确测量,研制了XL-01 xDSL线路综合测试仪,它能够在用户线中对其固有衰减、环路电阻、模拟通信质量和工作电容等参数进行准确测量,挑选出符合高比特率数字传输技术参数的芯线对,为应用固定电话网的资源实现综合业务数字网建设的广大工程技术人员提供了实用有效的测量工具。
Considering the inaccurate measurement of every electric parameter of local call cable and the characteristic of decaying with the high speed existing in the telephone network user＇s line cable, XL - 01 xDSL subscriber line comprehensive tester have been developed. It can carry on the accurate measurement to their inherent decay, resistance of cycle, analogue communication quality, working capacitance and other parameters among subscriber line and select the core line according with the high bit of figures of leading and transmitting the technical parameter, which offers practical and offective survey tools for the engineers and technicians of Integrated Service Digital Network （ISDN） construction.
