Parts of the LATN (Local Access Telecommunication Network) planning problem can be modelled with the Extended Tree Knapsack formulation. The LATN can constitute up to 60% of total network costs. In this paper a partitioning algorithm using standard off the shelf software coupled with enhanced modeling is presented. Enhancements to the algorithms is presented along with empirical results. HE Local Access Telecommunication Network (LATN) connects individual subscribers to telecommunications networks through switching centres. Generally telecommunication networks are hierarchically divided into two or three parts, with the local access network contributing a large portion of the total network development cost, up to 60% according to in the case fixed line situations.
