Abstract: A network access optimization modeling initiative (NAOMI) that enables the operating personnel of a wide area service provider to configure the trunk connections of a telecommunications access network so as to gain access to the end offices of local area access providers at a given level of performance at minimal cost. Upon request, NAOMI optimizes the direct end office trunk and tandem trunk connections between the serving wire center (SWC) to which a wide area service provider gains access to a local area access provider and the end offices to which long distance calls are directed. In operation, NAOMI first obtains a configuration of the access network so that the respective positions of the points-of-presence (POPs) of the wide area service provider, tandem switches, end offices and various direct end office trunks (DEOTs) and tandem trunks of the access network are known.
