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.
