AACŪ - A Revolutionary Step in Testing ADSL-HDSL-SDSL
Thanks to the innovative Active Analogue Concept (AACŪ), 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.
Lines can be simulated starting from standard libraries (ETSI, ANSI, Bellcore, ...) or by entering
line parameters collected in the field. An additional key benefit is the ability to vary one parameter
while holding all the other parameters constant. The LSX 2020 is bi-directional and simulates very
accurately the delays, which occur in reality. Furthermore, NOISE and NEXT can be programmed via the
built-in generators or via the inputs for external sources.
Because of the fully configurable and programmable approach for any line setting, the LSX 2020 is the
first line simulator which allows creating any test line in order to determine the maximum performance
of a DSL transmission system.
