Transpac (data network)

Transpac, also written TRANSPAC, was a French public data network that operated from the December 1978 to June 2012.

History

edit

It was opened in December 1978 by the semi-public Transpac society.

It offered the X.25 interface to its users, the CCITT standard of 1976 for which computer scientists of the Centre national d'études des télécommunications (CNET) had played a major role. This network has been part of the worldwide X.25 network which, before the Internet, permitted data exchanges around the planet.[1]

Initially created for professional customers, it was later used by millions of French terminals Minitels to access consumer applications, forerunners of those of the Internet.[1]

In 1987, Transpac was the world's largest public packet-switched network with revenues of nearly $400m.[2] Minitel videotex services accounted for 45% of its data and 20% of its $678m revenue in 1990.[3] By 1991, it was operating in fifteen European countries.[4]

France Télécom closed the Minitel service, and the Transpac network via which it was available, in June 2012.[5]
