Selected DSL Standards Contributions

I have also led standardization of proposed novel dynamic spectrum management (DSM) algorithms for copper-access networks in ATIS COAST-NAI committee in USA and NICC committee in UK. The proposed algorithms are now included in “ATIS DSM technical report 2” and “NICC report for DSM methods on the UK access networks.” List of selected standards contributions is below
