 From 1999-2000, Cabello was head of the national telecommunications commission (CONATEL).The main telecommunications law he helped promulgate, known as the "Organic Telecommunications Law" (2000), was especially praised by the private sector.Specifically, it ended the state's prior monopoly on the industry and fostered a significant level of free-market competition, as Cabello's work helped increase the treasury's revenue by $400 million dollars at a time when oil prices were not especially high.
