In the deployment and maintenance of operators broadband service，there is a need of xDSL to judge line quality.
DSL-3011A xDSL Tester developed by DADI Telecom is a portable handheld ADSL/ADSL2/ADSL2+line test and analysis instrument, which can test physical layer, network layer and application layer quickly and accurately. It is a necessary tool for xDSL line deployment and maintenance.
ADSL2+ Modem replacement
?l xDSL physical layer testing：Test upstream, downstream, maximum speed and channel utilization and Test upstream and downstream noise margin, and output power and power attenuation
?l xDSL network layer testing: Ping, PPPoE dialup trace route test
?l xDSL application layer testing：web browsing, web speed and FTP measurement
?l network layer testing：Ping,Ipconfig,PPPoE dial up,route and trace route, etc.
?l Tone generation：Send tone generation signal one side of line and identify current testing line through audio sensor on the other side.
?l DMM testing：test loop resistance, insulation resistance, capacitance, AC/DC voltage and line length estimation
