Executive Summary

As field trials and initial deployments of Vectored DSL systems materialize in the next few years, Vectored DSL systems will often co-exist with non-vectored DSL systems sharing the same cable. For such mixed-binder scenarios with vectored and non-vectored lines, this paper presents an optimal Dynamic Spectrum Management (DSM) technique referred to as Mixedbinder Optimum Spectrum Balancing (MixOSB) to find the optimal transmit PSD spectra. When the mixed-binders have short vectored lines and long non-vectored lines, simulations show that MixOSB has substantial performance gains over applying existing DSM techniques independently to the vectored DSL systems and non-vectored DSL systems because it reduces the interference induced by the vectored lines on the non-vectored lines.
