It's just ssh. My local library did have a dial-up line for the longest time but I think they finally retired it, that's the last one I might have actually used.
I think the last one I used was in 2003. My university offered it for internet access. It was actually just dial-in shell access, but you could tunnel an internet connection using Slirp. Nice and slow.
But really, was that a cute way to describe ssh, or are you actually dialing into stuff in 2017? Because that would be weird, but kind of cool.
