My new bedtime reading has arrived…

In the UK, AC13 telephone signalling used pulses of 2280Hz to represent the digits of a dialled phone number, call progress state etc.

This training document from 1983 was pretty late in the lifespan of in-band signalling like this, which had been around for 20+ years by this point.

It’ll be fun reading this from a “what would it do if I poked $thing at $time” point of view

This is extremely silly.

I have a Nokia 105 #phone. No data or apps. Just a plain, dumb, mobile phone

Using a sim from aa.net.uk I've connect it to the C*Net VoIP network https://ckts.info

It's accessible on a CNet number, and can place calls just like any other phone on CNet!

Do I need this?
No.

Can it make normal calls?
Absolutely not!

Is it useful?
Not in the slightest.

Is it cool as heck?
Absolutely!

I'll make a demo video later…

It's been 40 years since #EmmanuelGoldstein launched the seminal, essential, world-changing @2600: The #Hacker Quarterly. 2600 wasn't the first #phreak/hacker zine, but it was the most important, spawning a global subculture dedicated to the noble pursuit of technological self-determination:

Found this instance of what is, essentially, anti-Soviet hacktivism by US phreaks back in September of 1986, from the Herald-Journal.

You know you're #OldSchool when you see a phone number on a CV and immediately go "oh 317, they're from Indiana". #phreak #geek #infosec
