Description

technical field [0001] The invention relates to DSL equipment testing equipment, in particular to an automatic line switching device for DSL equipment testing. Background technique [0002] xDSL (including ADSL, VDSL, HDSL, SDSL, etc.) is a high-bandwidth, low-cost broadband user access system. According to data from the DSL Forum, by the end of 2004, the number of global DSL users had grown rapidly, and the total number of Chinese users had reached 16 million lines. And the demand is still increasing. Since there are many manufacturers producing xDSL office communication equipment and user-side terminal equipment, there is a big problem in the compatibility of their products. Interoperability and compatibility between xDSL access terminals and access central office equipment of different manufacturers has become an important item in broadband access network testing. [0003] Because there are various products of central office access equipment and terminal DSL Modem, and...
