RetroNetCall: "Datex-L, the German CSPDN"
I've presented about Datex-L, the German CSPDN (Circuit Switched Public Data Network) as part of the RetroNetCall talk series on retro-networking technology.

I've always been fascinated by "ancient" data communications - both the kind that I personally consciously witnessed from the late 1980s as well as the kind that I never experienced myself (like Datex-L).
I am not an expert in the subject by all means, as I was never involved in its design, implementation or even used it. However, given that there's very few public information online about Datex-L and/or other CSPDNs, I thought I could improve the situation by presenting about it.
