N2 - Dynamic spectrum management (DSM) has been recognized as a key technology for tackling multi-user crosstalk interference for DSL broadband access. Up to now, DSM design has mainly been focusing on maximization of data rates. However, recently, reducing the total power has become a main target, as IT power consumption has been identified as a significant contributor to global warming. In this paper we extend traditional DSM design towards a much wider energy-efficient scope and show how to tackle the corresponding optimization problems. The impact of this 'green DSL' approach is evaluated for practice with some surprisingly good numerical results. Furthermore bounds are provided on the trade-off between data rate performance and power saving.
