Buenos aires fundamental plan, 1931-1950

With the progress of the telephone art and in response to the demand of the public for a more efficient service the United River Plate Telephone Co. decided early on the conversion of Buenos Aires from the manual to the automatic telephone system. In 1923, four automatic exchanges were cut over in the Federal Capital. A fundamental plan was made in 1924 covering a period of ten years, and the first automatic offices inaugurated under that plan were opened in 1927. In 1930 a new fundamental plan study was commenced. This plan covers the provision of telephone plant in Buenos Aires and suburbs, and is based on a line and station growth as indicated by a block-to-block commercial survey made in 1930-1931. The paper deals with the data collected in the course of the preliminary work necessitated by the survey mentioned above.
