IIRC Gandalf (the company, not the wizard) got it start with a large
distributed multiplexer that ran over coaxial cable and allowed N+M
terminals (w/serial IO ports) connect with N minicomputer (e.g. Digital
VAX730/750/780) IO serial ports, but only N ports at a time. There was a
Gandalf box at the terminal and (I assume) a much larger box at the
minicomputer. The Gandalf systems were in wide use in colleges and
universities before LANs ( & WANs MANs) and the Internet as well as PCs
arrived on the scene.
Gandalf expanded its product line with Limited Distance Data Sets (a
sort of modem) that had higher speeds than dial up modems and worked
over copper wire spans of up to 1 or a few kilometres, but not over
telephone circuits. The company continued to expand its product line in
the data-communications area until the company folded.
Wikipedia: /DATAPAC/ was Canada's packet switched X.25-equivalent data
network. Operated first by Trans-Canada Telephone System, then Telecom
Canada .... discontinuing the service at the end of 2009.
And, Glenn is probably correct, in that Datapac was probably a Nortel
customer and used their equipment in the network.
On X.25, I recall working with a Memotec PAD in an employers R&D dept..
Found on the Google: /Memotec was a leading provider of inter-office
voice and data networking solutions, specifically the packet
assembler/disassembler (PAD) device commonly found in X.25 networks./
