SPIRENT DLS SPIRENT PHYSICAL LAYER SOLUTIONS DLS-8240 EUROPEAN MIXED IMPEDANCE SIMULATOR European xDSL Wireline Simulator OVERVIEW Network equipment manufacturers, chipset designers and service Increasing demand for high-bandwidth multimedia applications with integrated voice, data and video streams has been driving providers seek competitive advantage by being first to deliver reliable products or services to the market. The DLS-8240 line xDSL deployment. The requirement for high-speed transmission over the traditional copper network has driven the continuous simulator allows users to test the impact input impedance has on a modem’s performance by providing wire gauge types that have advances in DSL technology. From a standardization viewpoint, this has been reflected in the introduction of the most recent DSL a wide range of cable impedances. Spirent solution users know that simulation of proper input impedance, delay/phase and initiative—VDSL2. While VDSL2 is the next generation of VDSL1, it is also designed to ensure compatibility with existing access insertion loss are key to delivering robust early product delivery to market. Each wire gauge type has a reach from 0-90m in network solutions such as ADSL, ADSL2 and ADSL2+. 1-meter increments, allowing users to characterize very precisely the impact small changes in loop length have on a modem’s performance. By combining various wire types that have a large variation in impedance, small changes in loop length will cause DLS-5500 a shift in reflected frequencies to allow users to see the direct impact this has on a modem’s performance.
