I mean, network cabling is the same unshielded twisted pair wiring we’ve used for analog telephone audio over the last 150 years.
Networking uses 4 wires in 2 pair for 10mbps and 100mbps. You need the full 8/4 for gigabit and above. Telephone uses 2/1.
Telephone cable has 4 wires in it:

It has 4 wires, but you only need 2 for normal single landline use. The second pair is for a second line.

In case you’re wondering, some broadcast equipment, such as the Axia Radius, uses Ethernet sockets for the connection of balanced and unbalanced audio.
This simplifies cabling, but you need adapters at the end of each cable to go back to RCA, TRS, XLR etc.
Some networking equipment has serial ports (RS-232) that use RJ45 connectors. 3.5mm TRS connectors are also commonly used for serial ports.
This looks so cursed
In my home studio I have a Behringer S16 digital snake which connects to my X32 in the control room with only a single CAT5 cable in between. So it’s literally sending 16 channels of audio with a single ethernet cable. Pretty cool!

Fun fact: usb uart to audio jack is actually a thing: https://ae01.alicdn.com/kf/HTB1G43QaOnrK1RjSsziq6xptpXaN/win8-10-android-mac-pl2303hxd-usb-uart-ttl-to-2-5mm-audio-jack-serial-adatper-cable.jpg
Some older android phones used the audio jack double duty as a serial debug console, the nexus 5 for example.

Yes, it’s awesome!
So, how does the internet sound?
sounds like advertisements
Is this a USB Ethernet adapter for one of those weird older devices that used 2.5mm for USB?
This is likely an adapter for a switch or router to access it’s debug console.
Finally, I can connect my Sinclair ZX Spectrum to Ethernet!
Only if you have the TRS to D-DVI converter, and those are super super rare.
This is so you can record the dial-up sounds.
Finally! I can yell at the internet!
And it will be just as useful as without that adapter.
No you can’t. That’s stereo. You can only hear the internet yell at you.
You’d need three lines for an output.
This will be handy when I need to run my industrial machines from USB.
This could come in handy for my USB industrial smelting oven
Useless, you can’t charge from USB-a!
(Seriously, it would be a fun project to stuff a USB powersupply in the 400v plug and a add a USB-c cable to mess with people at work… I’d do it but we only have 230v 3-phase outlets and that plug is probably too small.)
I think you can fit a fairly powerful GaN charger in that space.
Can I do dial-up over VoIP?
i made a male version of this 4 times and then bought a ABC RJ45 switchbox for my work desk, so i could choose between computer audio and desk phone audio and cellphone audio through my work headphones… lets you bump your own music in between calls without dealing with pause buttons etc… worked great.
How else did you think they got the dialup noises to play?
Dialup didn’t use ethernet.
Care to elaborate? I can’t find any information searching online.
No.
Ethernet is rj-45, dialup used 11/25
Thats wrong. This is how they got dial up to play
