• ADSL Physical Layer Test
• Support all of the present ADSL standards:
• NSI 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+).
• Fast and Interleave signal channel BER test
• Test downstream, upstream rate and channel availability of the line
• Measure upstream and downstream noise margin, output power, and power attenuation
• Bit error statistics of NEC, FEC, CRC, and HEC
• Automatically detect and display LOS, LOF, LOP, LOC and Border Loss with the comparison between history and presence.
• ES statistics
• Display bit distribution of each tone in the graphical and digital way
• ADSL Network Layer Test
• Support several upper layer protocols, i.e. RFC1483（RFC2684）, PPPoE（RFC2516）, DHCP and PAP/CHAP etc.
• PPPoE /DHCP dial-up to acquire IP address and Ping test
• Fixed Ping test
• Ping tests include Ping loss test (able to define number and frame size), Ping loop back delay test (Max, Min, Avg)
• Replace ADSL2+ Modem
• Ethernet Test
• LAN Ping test
• Cable Test
• DMM: including loop resistance, insulation resistance, capacitance, DC & AC voltage and line length estimation test
• Audio line-tracking
• Auto-off
• Sound and LED alarm indication
• Test data management
• Software on-line upgrade
• Pass/fail indication: determine the line quality by comparing the practical test result and the parameter threshold value of key lines set by the user
• Audio line-tracking: send audio signal at one end and identify the present line by testing at the other end through the audio inductor.
