Part of the VeEX Modular Test Toolkit (MTT) family of products, the MTT-51 UDSL Module for the MTT Platform provides an ‘All-in-One’ universal DSL infrastructure test capability. The MTT-51 addresses some key innovations in DSL, including Vectored VDSL2 and Two Line Bonding. VDSL2 Vectoring provides advanced DSL crosstalk cancelling capability for all pairs in a given binder group, that yields enhanced line rates for these multiple subscriber lines. Bonding two pairs provides inherent performance improvements in the form of greater line rates for the same distance or longer reach capability. Also supported in the RXT-1200 platform.
