Lesson plan

DATAPAC

DATAPAC, or Datapac in some documents, was Canada's packet switched X.25-equivalent data network. Initial work on a data-only network started in 1972 and was announced by Bell Canada in 1974 as Dataroute. DATAPAC was implemented by adding packet switching to the existing Dataroute networks. It opened for use in 1976 as the world's first public data network designed specifically for X.25. Operated first by Trans-Canada Telephone System, then Telecom Canada, then the Stentor Alliance, it finally reverted to Bell Canada when the Stentor Alliance was dissolved in 1999. Like most X.25 networks in the western world, DATAPAC services were largely replaced by TCP/IP in the 1990s and 2000s. Bell phased out the service on 31 December 2009.
