Functions ADSL Physical Layer Testing: ADSL2+Modular: full support all ADSL standards, which includes 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+). Test upstream, downstream, maximum speed and channel utilization. Test upstream and downstream noise margin, and export power and power attenuation. Test error value of proximal end and remote end FEC/CRC/HEC/NCD/OCD. Auto test and display proximal end and remote signal loss, frame loss, power loss, cell loss, border loss and many other Defect information, along with history record contrast to the current display. Statistic error seconds. Display every sub-channel of Bits per Tone by the mean of graphic and number. Display every sub-channel of SNR per Tone by the mean of graphic and number. ATM F4, F5 OAM loopback test. ADSL Network Layer Test: Support RFC1483RFC2684,PPPoERFC2516, DHCP,PAP/CHAP and variety of upper layer protocols. PPPoE dial-up obtain IP address and Ping test. Fixed Ping Test Ping test that includes Ping loss test (Be able to identify times and package size), Ping loopback latency test(To test its MAX ,MIN ,Average level ). Router tracking test Replace ADSL2+ Modem ADSL Application Layer Test: Net Scan Net Rate Measurement FTP Speed Measurement Ethernet Test DHCP client testPPPoE dial-up is used to test the problem from users IP broadband or LAN. Network layer test: Ping, Ipconfig, Route and router tracking, etc. Application layer test: Net Scan and rate measurement, and FTP speed measurement. Cable Test Digital Multi Meter (DMM) is used to test loop resistance, insulation resistance, capacitance, AC-DC voltage and estimate wire length. Audio line tracking Others Auto Power-off Beep and LED alarm. Data management test Software on-line upgrade
