Abstract

A methodology for optimizing the cost associated with access charges incurred by network service providers when leasing communications facilities from a local service provider has been developed that incorporates physical reconfiguration of the access network topology as a cost-saving measure, where and when appropriate. The methodology identifies opportunities to reduce access charges by performing the following functions: (1) moving T1 facilities from one hub location to another; (2) moving T1 facilities from one T3 facility to another (at the same hub location) in order to disconnect unneeded T3 facilities; and (3) adding new T3 facilities in order to reduce overall access expenses and/or to provide new capacity for future growth, including adding potential new hub locations. The methodology is appropriate for use with various types of network facilities, T1 and T3 being considered as exemplary only.
