It is interesting how the marketing of Centrex has changed. Shortly before divestiture, it was very rare that a local operating company would want to sell Centrex service, probably because of the expense of all of those lines. They would rather sell a Dimension(r) plus a service contract. After divestiture, since they could not sell PBX's any more, suddenly Centrex marketing took a very large jump. Should the Bell companies get permission to start manufacturing, I wonder if Centrex services would become a pariah again. John Haller att!ihlpl!jhh
