Direct-dial long distance callsIn 1951, direct-dial, coast-to-coast telephone service in North America began as Mayor M. Leslie Denning of Englewood, N.J. called Mayor Frank Osborn in Alameda, Calif. Three digits were added to the number dialled. They were able to begin taking just 18 sec. after the dialling. Previously, coast-to-coast calls were placed by long-distance operators. Since the 1930s some calls could be dialed between cities and towns with relatively small areas. By 1965, 9 out of 10 telephones used the new service, with millions of users connecting through thousands of new generation switching centers, with a numbering plan that could be applied nationwide, and a billing system that could record and process millions of transactions automatically. |
