FYI - 2600 Hz is a common handshake tone used in telco. Hence why “2600” is referenced. https://en.m.wikipedia.org/wiki/2600_hertz

Lots of fun history around 2600Hz for those too young to remember or not part of the phreaking crowd, a fairly extinct form of hacker these days. A phreaker going by Joybubbles was the first to exploit the tone by whistling. Later, a toy whistle in a cereal box was found to be able to produce the tone, leading to further exploit by John Draper, aka, Cap'n Crunch. You can 3D print the whistle these days for a bit of n…

Always important to remember that the telecom revolution was underway in 1890, let alone 1990. I still think the telephone system trumps the Internet in terms of revolutionary impact on society.

Is this where the name of the zine came from, I guess?

Yes. Details under "Publication History": https://en.m.wikipedia.org/wiki/2600:_The_Hacker_Quarterly

And "Blue Boxes" exploited the 2600Hz signal to make free phone calls, explained here under "Operation": https://en.m.wikipedia.org/wiki/Blue_box

Steve Wozniak built Blue Boxes and Steve Jobs sold them: https://artsandculture.google.com/asset/blue-box-designed-an...

This predates me by at least a decade. How do you use the “BBS”? So once you dial in, it uses IVR to read and write messages?

Sounds painful to me once you have more than a dozen active users

Sweet, I've been looking for one of these to test CSD calls out for the first time in like 20 years before GSM gets shut down on T-Mobile. There was one other service in Vancouver that probably shut down last year but I'm not sure data calls work internationally. EDIT: This is that service if you are a Canadian that wants to try it, https://www2.vcn.bc.ca/free-internet-access-via-dial-up/

Could you theoretically use an analog modem (or worst case an acoustic coupler) over IMS (VoLTE etc., which should all have at least some QoS), or are the jitter rates and codecs too bad for that (like they often are for Fax over VoIP on fixed lines)? I wonder if some of the networks that are continuing to offer GSM (usually via some core network emulations, as far as I understand, to make it more compatible with mod…

We still have 2G on all carriers in Russia with no plans to shut it down (no plans to introduce 5G either though). But I'm not sure there are any operational dial-up providers left I could test CSD with. But I am now curious to test it.

It’s just text interface like running a program on a terminal, just the program runs on the remote computer. Much like a telnet session, with some primitives to transfer files.
