The art of deploying DSL : Broadband via noisy telephony wiring - Whitepaper DSL01
other
The huge spread in crosstalk coupling between the individual wire pairs of a telephony cable makes it a significant challenge to deploy systems such as ADSL and VDSL2 in high volumes. Trial-and-error deployment strategies with adaptive bitrates may have worked well in the past for offering an “elastic” service such as Internet Access, but more careful planning is required to deliver Triple Play services. DSL operators who introduce VDSL2 can take advantage of the operational experience gained from millions of ADSL lines. This article explains the effects and consequences of spread in crosstalk coupling between wire pairs and discusses an initial strategy for deploying VDSL2.
