Abstract
The Digital Subscriber Line (DSL) network is a robust and economical access architecture that has continuously evolved to meet the challenges of changing demographics and increased service demands. Advances in copper data transmission technologies have enabled traditional wireline telephony service providers to keep up with demand as residential customers order more and richer content. For the near term, the DSL architecture will continue to be the primary workhorse for many applications, however; accelerating growth in bandwidth demand and strong competition from alternative broadband access technologies will significantly change the landscape moving forward. To keep pace, operators must consider ways to continue evolving their network in a cost-effective and methodical manner that will guarantee competitiveness long-term.
