Standards evolve from best practices and industry consensus, and a new document that identifies best practices for Dynamic Spectrum Management (DSM), the ATIS Dynamic Spectrum Management Technical Report Issue 2, is an important step forward. In most parts of the world, fixed broadband service providers have renewed their commitment to DSL and indefinitely deferred significant investment in alternative fixed technologies such as FTTH.
DSL, most notably vectored VDSL, can deliver broadband speeds in excess of 100 Mbps when managed with DSM techniques, meeting all known regulatory and market requirements for broadband access within the next ten years.
Proper use of DSM is also essential to mixed deployments of vectored VDSL and unvectored DSL, which will arise in most practical deployment scenarios (regardless of whether the DSL access equipment is managed by a single provider or by multiple providers). The release of Issue 2 of the ATIS DSM Technical Report is especially timely, as these issues are among its central topics.
The DSM best practices in the report were defined under the consensus process of the Alliance for Telecommunications Industry Solutions (ATIS) by members of the Network Access Interfaces (NAI) subcommittee of the Copper/Optical Access Synchronization and Transport Committee (COAST) committee, including worldwide carriers, equipment and software vendors, and academic institutions.
The DSM technical report was first published in April 2007, and Issue 2 was approved on November 1, 2012, substantially updated, with better organization for a clearer and broader delineation of different DSM techniques and their performance.
The report provides further validation for the value of DSM and vectoring (both created by ASSIA inventors) for advanced broadband services. Its release coincides with the release of ASSIA DSL Expresse 3.1, which is the only spectrum management solution capable of simultaneously managing vectored and non-vectored lines from multiple vendors in the same cabinet.
As more and more service providers join the worldwide tidal wave of implementing vectored VDSL, the ATIS Dynamic Spectrum Management Technical Report Issue 2 serves as an important, vetted guide to current best practices of DSM, especially as it relates to vectoring.
More importantly for consumers of high-speed broadband, service providers can now move forward with their plans to implement vectored VDSL2, knowing that their peers have thoroughly examined and agreed on best practices.
