Physical Layer 
Tango checks the performance identifying the causes of reduced bit rates. The analyses of the 256 ADSL DMT tones is a powerful trouble shooting tool that allows immediate identification of the fault.

Service Level Agreement
A specific service test report can be generated and identified with each customer showing the details of the promised ADSL service.

Bit Error Rate tester
AuroraTango generates dummy cells to calculate the line BER on both Fast and Interleaved channels providing a count of Errored Seconds .

DSLAM synchronization
A time stamped trace is generated of the Command/Response sequence protocol and detected . A list of error codes is provided to interpret the failure causes. The timeout threshold can be defined by the user before resuming synchronization.

IP ping
Using either IP address or DNS Client address and to check the way through the network with Trace Route functionality. It supportsPPPoE and PPPoA for service authentication.

Statistical Report
A test report can be printed. It itemises Attained, Fast and Interleaved Bit Rates, Noise Margin, Attenuation, Output Power and Relative Capacity. It provides graphical analysis of Carrier Load and Noise per Carrier as well as the events registerred during the training process.
