In short, the key to success is flexibility. When it comes to a DSL test plan, one size does not fit all. All three components discussed in this tutorial will evolve over time and improve. Tests will become more accurate, new test standards will be agreed upon, and spectral testing will become increasingly important. Test software and OSS integration needs will also evolve. New tools will give service providers real competitive advantages. Test access needs will also change in line with customer-service expectations and operational efficiency goals. By understanding each of the components of a DSL test design, service providers can design a modular platform that addresses immediate test requirements while remaining flexible enough to respond to unforeseen forces of change. The successful service provider will be the one that plans for change.
