Testeur xDSL DT-320

In the deployment and maintenance of operator’s broadband service, there is a need of VDSL to judge line quality. DT-320 VDSL Tester developed by Oxin Group 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 VDSL line deployment and maintenance.

Features and Benefits:
  • Large LCD touch screen
  • Windows CE OS, graphical interface, easy to handle
  • Net Scan freely and easily
  • Cable qualifies indication: Auto setup critical line threshold parameter, with comparing real test result with threshold to indicate the cable qualification
  • Audio line-tracking: Send audio line-tracking signal at one end, and then identify the testing line with audio sensor at the other end
  • Auto Power-off
  • Beep and LED alarm
  • Data management test
  • Software on-line upgrade
  • 'ATUR+PC' emulation
  • ADSL2+ Modem replacement
  • Ping testing
  • DMM testing
  • Tone generation
