S-210 ADSL2+ TESTER It is a small, fseull-featured data maintenance instruments, and automatically adapts to all kinds of ADSL lines standards, so it is clor to the actual needs of maintenance with user-friendliness, conveniently testing. It can not only help to confirm the opening of business lines but also can assess the service quality. The keyboard design makes the amendment of username and password conveniently. Standard: ITU-T G.992.5 (ADSL2+) ITU-T G.992.1 (G.dmt) ANSIT1.431 Issue 2 ITU-T G.992.2 (G.lite) ITU-T G.992.3 (ADSL2) RE-ADSL2 ITU-T G.992.4 (Splitterless ADSL2) Supporting mode: Support RFC 1483(RFC 2516) bridging mode and routing mode Support PPPoE(RFC2516) PPPoA(CFR2364) Support LLC/VC MUX Support PAP/CHAP Function and specifications: Compatible with ADSL/ADSL2/ADSL2+/READSL ADSL physical testing: Line attenuation, line noise margin, the uplink and downlink channel rates, the largest upstream and downstream rate, power output, number of remote and nearby proximal errors(CFR、JEC、FEC、NCD、OCD), function and feature map of 256/512 sub-channels and sub-carriers under DMT modulation, showing DSL routes linking mode. DSL network testing: Properties of PPPoE、PPPoA dial-up and dial-up modifications, after the success of dial-up, one can get and check IP-IP, the first DNS server IP, the second DNS server IP addresses to validate the connectivity from user's to ISP services, PAP and CHAP optional, Ping testing, and packet loss rate test.
