A short overview of the VDSL system requirements

This article gives an overview of VDSL and summarizes the main system requirements developed by ANSI-T1E1.4, ETSI-TM6, and ITU-T Study Group 15/Question 4 in a coordinated effort. For the time being, both single-carrier modulation and multicarrier modulation schemes have been proposed for standardization. VDSL is an enabling and cost-effective access solution for the last mile of the network over ordinary existing telephone lines. This new standard targets aggregated data rates up to 52 Mb/s on short loops. VDSL can be used to provision broadband services for both residential and business.
