In the view of engineering application of IPTV ADSL access technology, an overall scheme of IPTV ADSL test module based on embedded Linux is proposed and designed. Further, the test index, the software and hardware's interaction and the test flow for ADSL test module are discussed. The testing result indicates that this test module does not only satisfy the testing of ADSL performance index, but also has the simplify operation and the good graphical user interface.%针对IPTV ADSL接入技术的工程应用,提出并设计了一种基于嵌入式Linux的IPTV ADSL测试模块的总体设计方案.在此基础上讨论了ADSL测试模块的测试指标、软硬件交互、测试流程.测试表明,测试模块不仅能够满足ADSL性能指标的测试,而且易于操作,具有良好的图形用户界面.
