Title: Dynamic Signal Management

Abstract: Dynamic Signal (or Spectrum) Management (DSM) improves the rates, ranges, and operational costs for Digital Subscriber Line deployments, and is beginning use at several major telephone companies. This talk overviews the area, specifically addressing the DSM methods for polite power and spectra use, impulse noise control, and vectored crosstalk coordination. The architecture of a typical DSM system is also overviewed and the stages of implementation are also enumerated.
