Thanks to the innovative Active Analogue Concept (AAC®), it is possible to precisely reproduce any line distance and any line characteristic in the lab just the way it behaves in the field and this without changing the hardware. The LSX 2020 offers the ability to create lines of which all parameters can be configured in almost unlimited ways. This way developers and manufacturers of DSL chipsets, modules or modems can easily create any possible line in order to fine tune their products while operators can select the best performing transmission system for their different lines.
