iSMART Consortium tested souped up version of VDSL2

Recent deployments by large incumbent carriers Qwest and TeliaSonera are proving that VDSL2 can deliver multi-megabit speeds over existing copper, but impairments will severely degrade what's actually delivered to the end-user. However, the iSMART Consortium believes that the advent of Dynamic Spectrum Management (DSM) Layer 3, a technology that can eliminate crosstalk issues, will enable service providers to expand the rate and reach of VDSL2.  

iSMART recently conducted a trial of DSM L3 with three unnamed Tier 1 telcos, according to the company. During the tests conducted by consortium members ECI Telecom and Actelis Networks, iSMART claimed that DSM L3 technology was able to eliminate crosstalk interference issues on twisted copper pairs. Other than saying that DSM L3 could increase the reach and rates by 10x in some cases, iSMART gave little details on what speeds or reach were achieved during the tests.

Nonetheless, if DSM can perform as advertised it will be a boost for the majority of incumbent service providers that are looking to compete with cable over their existing copper-based networks.  Although it would not reveal the three operators that participated in the DSM demonstration, ECI Telecom said in an interview with FierceTelecom that the consortium is seeing interest from other Tier 1 service provides in Europe and the U.S.
