Automated test system for ADSL equipment

To achieve a competitive edge, reduced development cost, timely product delivery and product quality are the essential requirement for today's organization. Manual testing, requires skill workers which increases cost; increases testing time which delays product delivery; reduces number of test cases which affects product quality, is not a desirable choice. The low cost PC based automated system helps to get an edge by fulfilling the today's organization requirement.;The automated testing system described in this thesis is developed to support functional testing of all testing phases of Nortel's 1-Meg Modem System (SUT). The SUT is an inherently complex ADSL product and its testing is far more complex than just verification of process faults. The complexity of ADSL system, renders automated test system an important and imperative part of ADSL testing.;The requirement for an automated system has greatly increased due to the realization that manual testing is associated with additional resources and staffing constraints, which takes 15 to 90 minutes to run a single test on the SUT. Manual testing also requires additional time to perform re-execution for debugging and validation for fault correction. Whereas automation can do multiple re-execution of each test thereby increasing the amount of regression testing dramatically and improving the quality of feature testing on the SUT.;This thesis shows the indispensable requirement of automated test system for ADSL testing and its advantageous of developing a competitive edge for the organization.
