This paper solves the problem of designing an access tree network for which the users are connected to the switches through SONET channels on fiber optics links and ADM equipment at the nodes. The economies of scale provided by the SONET hierarchy are specifically taken into account. A fast tabu search method is proposed and its details are thoroughly discussed. Results are provided for a set of random cases as well as for a real network.
