Introduction:

ADT166 is providing solution for ADSL2+ line and modem test. It can quickly locate where the problem point is by synchronized judging test between DSLAM and terminal user. Using ADT400 as user terminal, after synchronized with DSLAM, we can know the situation of ADSL and cable by the provided upstream and downstream rate/power attenuation/signal-to-noise/Cyclic redundancy check (CRC)/channel and protocol version information. These help analyze operator’s service quality. ADT400 also offers physical test as line voltage, loop resistance, insulation, capacitance, frequency domain attenuation, which is good for cable selection and after-sales maintenance of ADSL2+.
