Abstract
A method and system is provided for use in cooperation with a computer having a memory for generating an optimized transition plan for the placement and interconnection of carrier hubs in a local access network having a plurality of Central Offices (COs), Serving Wire Centers (SWCs) and Point-of-Presence (POP) exchange carriers such that calls may be routed at least cost. In operation, the total number and location of existing SWCs within the network must be determined along with the total switched and special access demand. Thereafter, known tariff rates for selected channel terminals, transport channels and multiplexers must be determined along with the total number of DS3 lines from each SWC to its corresponding POP. By expressing determined network demand as selected mixed-integer program decision variables and determining a corresponding set of logical constraints consistent with these decision variables, the optimized placement of hubs within the local access network may be determined. In addition, the corresponding location and type of channel terminals, transport channels and multiplexers may be implemented all accordance with the mixed-integer program and an electrical sig…
