Digital subscriber line (xDSL) test system and test method thereof

Abstract

The invention discloses a digital subscriber line (xDSL) test system and a test method thereof; the system comprises a computer, a controller and a test module; the controller and the test module are connected to form a test loop; the test module comprises an impedance source module, a filter module and a load impedance module which are serially connected; the impedance source module comprises a plurality of impedance sources and a first relay; the filter module comprises a plurality of filters and a second relay; the load impedance module comprises a plurality of load impeders and a third relay; consequently, the on / off of the first relay, the second relay and the third relay are controlled through the computer, so that the appropriate impedance source, filter and load impeder are connected into the test loop after automatic selection to accurately and effectively test all the functions of a digital user line; and according to the invention, test equipment is optimized, the number of matchers is reduced, the operation is very convenient, a test cycle is shortened, so that the test efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technology in the communication field, in particular to an xDSL test system and a test method thereof which can simply and effectively test xDSL. Background technique [0002] xDSL is a general term for various types of DSL (Digital Subscribe Line), including ADSL, RADSL, VDSL, SDSL, IDSL, and HDSL. [0003] xDSL is a new transmission technology that uses higher frequency and corresponding modulation technology on existing copper telephone lines, that is, uses signal processing technology that adds or obtains more digital data in analog lines to obtain high transmission Speed ​​(theoretical value can reach 52Mbps). Most industry observers and the telecommunications industry are familiar with xDSL technology. xDSL achieves a wider bandwidth than analog voice calls by using frequencies above 4 KHz. For traditional residential ADSL services, more bandwidth is used to send information to downloading users. At the same time,...
