History

Red Especial de Transmisión de Datos

Iberpac evolved from the Spanish Red Especial de Transmisión de Datos (RETD), the world's first public operated packet switching network. Created in 1971, RETD was based on general-purpose Univac 418 III computers.
Project TESYS
By 1978, project TESYS(Telefónica,SECOINSA, SYTRE) started the development of specific-purpose switching nodes. Some of the design principles of TESYS nodes were advanced for their time (MULTRIBREAGING, TOKEN RING protocols). In contrast, the large user base with terminals based on legacy RSAN protocols slowed the adoption of x.25, TESYS product development and support were targeted to CTNE only (thus precluding the spread of TESYS to international markets) and data lines in Spain became slow for their time (only 2% lines above 1200 bit/s in Spain in 1982, compare 89% in west Germany).

Iberpac and Red UNO X.25

Renamed as IBERPAC, the network evolved to X.25 in the 1980s, and it was renamed again as 'Red UNO' in the 1990s. Bank branches and financial services conformed the main user base. IBERPAC enabled new videotex and teletest services, although the adoption lagged far behind the popularity of similar services in other countries, such as the French minitel. Services based on legacy RSAN protocols were definitely scrapped in 1996.
