Context

Country: Canada
State/Province: Ontario
Period: 1988+
Canada: Launched by Bell Canada in Montreal in 1989 & Toronto in 1990, Alex was last major attempt to commercialize videotex service in Canada. Using either terminal or PC, Alex offered residential users access to variety of information, messaging & home shopping services via telephone lines. Alex was commercial failure, due in part to high usage fees & paucity of services but was precursor to internet & world wide web.
Function: Used to provide power to Alextel/NT9G52AA computer terminal.
Technical: Alex was formatted for North American presentation level protocol syntax (NAPLPS), which was based on Telidon system developed in Canada. NAPLPS excelled in rendering of digital images & offered users visually richer on-line experience than text-only information services employing ASCII. Alex users employed special purpose terminal or personal computer running NAPLPS emulation program, which connected to system by modem over telephone lines; at telephone central office Alex calls were handed off to videotex access point (VAP) which established link over Datapac, public packet switched data network, to remote computers providing information services.
