Abstract

Thanks to their high bandwidth capability, asymmetric digital subscriber lines (ADSL) and very high speed DSL (VDSL) are access technologies that permit the transmission of several applications simultaneously on telephone subscriber lines. Considering that these applications may require a different quality of service (QoS), and particularly different bit error rates (BER), for transmission, this paper addresses the problem of providing simultaneously two BERs for transmission over a DMT-based ADSL or VDSL link. Both coded and uncoded systems are considered
