    • ...Also, because MMM can be made compliant to current DSL standards, the benefits of its adoption will be illustrated in practical DSL scenarios with offthe-shelf modems, using the methods described in [17], [18] to estimate the crosstalk channel information and to impose the PSD masks to the DSL modems, respectively, as has been already done for rate maximization in [19]...
