ADSL qualification

ADSL lines are only pre-qualified by means of models that assume, without testing, the physical and electrical parameters. AuroraTango allows the verification of the copper loop by means of the key digital and analog parameters that govern ADSL service. Just connect to the line and within seconds you will to know its capability to provide the level of service required. Each circuit can be tested in this way until the loop has been fully qualified.

Test report available within seconds for on-site or further analysis

Physical Layer testing
AuroraTango analyses the ADSL Physical layer performance identifying the causes of reduced bit rates. AuroraTango analyses all the 256 ADSL DMT tones to provide reports of noise and load. The tone analysis is a powerful trouble shooting tool that allows immediate identification of the fault.

Service Level Agreement
ADSL providers can offer different levels of service depending on the customer requirements and also on the commercial strategy. 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 between Alcatel or compatible ADSL transceivers, ATU-C and ATU-R. The BER analysis operates on both Fast and Interleaved channels providing a count of Errored Seconds during the test period.

DSLAM synchronization
Attach AuroraTango to the circuit, press Start,and it will contact the ATU-C modem. It then starts the training phase when synchronised with the DSLAM. A time stamped trace is generated of the Command/Response sequence and other events to track the training process. A list of error codes is provided to interpret the failure causes.

Statistical Report
Information taken from the above operations can be printed as a statistical report. This itemises Bit Rates and Errors, Noise Margin, Attenuation and Relative Capacity. It provides graphical analysis of Carrier Load and Noise per Carrier as well as the events noted during the training process.

@ Modularity

The modular architecture of AuroraTango covers the requirements in today's extensive test environments. It provides for technological evolution without a large financial outlay.

AuroraTango gives the choice of three different user interfaces:

a colour PDA
a monochrome PDA
a simple One Button operation

Using a PDA allows you to integrate test processes with company applications. Carry your testing schedule on the tester.

The UNIversal Test Engine (UNITE) is the 'heart' of AuroraTango. It provides One Button operation using the keypad with Test and Print buttons.The Test Report together with the status LEDs and the Pass/Fail indication provides all the information necessary to the technician.

The Test Module provides support of the technology and test requirements
