Sparnex is a center of competence in copper transmission for more than 25 years. Key players in the DSL business are using Sparnex' LSX2025 physical layer platform for testing DSL modems on their compliance with ITU (and other) standards, as well as on maximum DSL performance in live networks since any live network can be reproduced. LSX2025 is cost effective because programmable for any standard, and 10 times more accurate than any other conventional DSL loop test box.

Sparnex 's automation station prepares your lab environment for modem training, modem show time, and traffic observation via easy-to-create script scenarios. Within minutes the system provides reliable consistent test results. The DSL Test Robot takes a few seconds to set up the line, loop and impairment test requirements for any DSL flavor and any DSL Standard, including ADSL 2plus.

The system can run hundreds of tests at any time of the day and night without failing just once. R+D engineers will dedicate quality time to the analysis of the test results.

Sparnex 's automation solution allows the Test Platform Managers to execute test plans with absolute accuracy, and on time.

Sparnex developed a revolutionary loop simulation concept which allows a precise simulation of all the physical layer characteristics : Copper Wire Length, Wire Gauge, Attenuation, Impedance, DC resistance, Temperature, Propagation Delay and Group Delay. LSX is the first physical layer loop system in the world to test SDSL, ADSL, SHDSL, SHDSL.bis, and ADSL 2plus for all the standards ETSI, ITU, ANSI and DSLF with one and the same hardware platform. With a simple click of a mouse you can start in a few seconds any standard compliance or modem performance tests for accurate and repeatable DSL tests. Conventional DSL looptest systems need different hardware boxes for each test, and test results depend on the testbox because line characteristics are not programmable.

Common mode, differential mode, micro interruptions, RF noise, Impulse noise, Combined Noise Models, AWGN, NEXT, FEXT, Physical Layer copper cable characteristics, PSD masks of modems/DSLAMS … the ICXACT - ANG Math 2005 can handle it all. The solution is very complete and includes easy selection and automation interfaces for measuring and generating any physical layer characteristic for Performance Testing of Next Generation DSL networks.

Unique is its capability to measure up to -160 dBm/Hz with an accuracy better than 0,2 dB ad 300 kHz. Country specific cable and noise characteristics can be regenerated in the laboratory just like they behave in the field. It is also the ideal tool to calibrate DSL loop simulators, and to accurately measure transmission equipment. Laboratory wiring, connectors, patch panels … can perfectly be characterised with the ultra-sensitive and accurate ICXACT.
