Global Survey Confirms Importance of DSL Acceleration Technologies to Telcos

Broadbandtrends recently conducted a global service provider survey of Telco operators regarding their plans to deploy VDSL2 Vectoring and  Both DSL Acceleration technologies employ noise-cancellation technology that enables operators to significantly increase the speeds offered over their existing copper infrastructure.

Key findings of the survey include the following:

  1. 57 percent of respondents are actively deploying VDSL2 vectoring technology or are  in trial and plan to deploy by the end of 2014

  2. The overwhelming driver for deployment of VDSL2 Vectoring is to offer faster speeds; with most operators planning to offer speeds of 50-75Mbps

  3. CPE compatibility remained the greatest challenge facing operators as they deploy VDSL2 Vectoring

  4. Operators have low expectations for self-installation of VDSL2 Vectoring, with only 19 percent expecting 60 percent or more of their customers to self-install

  5. The #1 challenge addressed by specialized software-based management for VDSL2 Vectoring was Qualifying customers for service 

  6. 42 percent of respondents are currently evaluating technology, while 52 percent are unsure of its impact on VDSL2 Vectoring deployments

  7. Alcatel-Lucent is perceived as the top VDSL2 Vectoring DSLAM vendor by respondents, followed by Huawei and ADTRAN


“DSL Acceleration technologies – whether VDSL2 Vectoring or offer an economic alternative to Fiber-to-the-Home –  providing an interim solution that can  offer customers faster speeds in a much shorter timeframe and at a much lower cost than FTTH”, notes Teresa Mastrangelo, principal analyst with Broadbandtrends

Broadbandtrends VDSL2 Vectoring Deployment Strategies and Vendor Leadership survey analyzes results from interviews with 36 incumbent and competitive operators in North America, EMEA, Asia Pacific, and CALA about their plans for VDSL2 Vectoring deployments.  The respondents, from all major regions, represent 31 percent of all deployed DSL lines at the end of 2013. In addition, the survey features operator ratings of 8 vendors (Alcatel-Lucent, ADTRAN, Calix, ECI, Huawei, Iskratel, KEYMILE, and ZTE) on 5 criteria.
