DA280 ADSL2+Tester, which is a handheld type of ADSL/ADSL2/ADSL2 + instrument for analyzing line test, can exercise rapid and accurate tests of physical layer of ADSL lines and network layer so as to be the necessary tool for Provisioning and maintaining ADSL lines.

Main Features   

• Support ADSL2/2+ technology    
• Full support for all current ADSL standards: ANSI T1.413 Issue 2, ITU-T G.992.1 (G.dmt), ITU-T G.992.2 (G.lite), ITU-T G.992.3 (ADSL2), RE - ADSL2 and ITU-T G.992.5 (ADSL2 +).   
• Support various kinds of upper layer protocols, such as RFC1483 (RFC2684), PPPoE (RFC2516), DHCP, PAP / CHAP, etc
• Available to use graphics and digitals to display bit distribution of each sub channel (Tone).  
• Have function for indicating qualified or unqualified line and support user-defined parameters threshold.  
• Support various kinds of ULPs, including RFC1483 (RFC2684), PPPoE (RFC2516), DHCP, PAP / CHAP, etc.
• Support PPPoE / DHCP IP address of dial-up access and Ping tests
• Support system of fixed IP Ping test
• Can conduct LAN Ping test
• Ping loss test (definable for number and packet size), Ping Circular delay (maximum, minimum, average) test  
  

Support ADSL2 + Modem replacement

• Support the tests of loop resistance, insulation resistance, capacitance, and AC-DC-voltage and estimation of the line length
• Test records can be sent to the PC through the serial port for display, storage, and printing. Powerful PC-side software -ADSL test data management system, can exercise data tests through detailed and comprehensive management and analysis  
• Free software upgrades
