We currently have a "C" based modeling tool that we use to design and optimize voice and data networks for both government and commercial customers. It uses published NPA/NNX info which maps to V & F coordinates. By using the V & F coordinates it computes distances which are used as tariff entries. We want to expand the model to include European PTTs. Compared to the US, the European tariffs are very simple. We use the Eurodata Foundation publications for basic tariff data. However, in order to calculate distances we have to use an approximate latitude and longitude of the locations we model. Until now this has been simple because the networks have been simple. Usually they have been the European branch offices of U.S. companies. We now have an opportunity to redesign and optimize the voice and data network of a major European bank. It has over 1100 locations in France and Belgium (branches, data centers and ATMs). To map spot the lat/long of every location would significantly add to the cost and/or data collection effort. Is there a counterpart to V & F coordinates in Europe? Can you determine the tariff location of a site based on its NPA/NNX (or European PTT equivalent?) Any knowledge or suggestions on how the European PTTs compute tariff distances will be greatly appreciated. As I said before the tariffs are simple, computing the distances to apply the tariffs is more complicated. Any assistance or advice will be appreciated and I'll post a summary of the results to the net.
