The group hopes that the answer will be found in the use of Dynamic Spectrum Management (DSM) to boost DSL speeds. "The main obstacle for the advancement of DSL technology is the interference ("crosstalk") generated from different DSL lines that share the same telephone cable binder," said Professor John Cioffi, Professor of Engineering at Stanford University, a pioneer of DSM research. "DSM is a promising technology for the future evolution of broadband access networks using existing copper infrastructure."

To avoid interference, current DSL implementations use static spectrum management that is built for a "worst-case" scenario. Most actual phone lines would allow for far better performance, and DSM technology will allow each DSL connection to be regulated in real time by the hardware based on measured crosstalk and on current data needs of each customer. The end result could be DSL connections that top out at 100Mbps or more.
