Archived report: this report was archived in April 2006 and has not been updated. We are no longer in the early adopter phase of the DSL market cycle. The increasing maturity of the market means that prices for all basic services are based on commodity product pricing so it is increasingly difficult for a carrier to survive without offering Value Added Services. In this environment the drive to increase the Average Revenue per User (ARPU) and reduce the Total Cost of Ownership (TCO) of the network increases in importance, as it becomes a significant factor in the difference between a profitable and non-profitable Access deployment. The key to a healthy ROI and profitability is not typically the total cost of the equipment, but the ongoing cost of ownership and the value added service revenue available to the Provider.
