Abstract

This paper presents a first cost analysis of a broadband local access system based on the switched star architecture. The per‐subscriber cost, including all network components from the customer premises interface to the central office switch termination, is established. Both near‐term and long‐range per‐subscriber costs based on technology trend forecasts are obtained and serve as a bench‐mark. These results are used for comparisons of the relative costs of offering different broadband access capabilities. The analysis identifies the most important elements in the per‐subscriber cost and explores trade‐offs and possibilities for cost reduction.
