The active telephone or dsl pair (normally Blue and white) goes to the middle two pins of the telephone socket. So 2,3 if 4 pins. Or 3,4 if 6 pins, or 4,5 if 8 pins..

I can’t speak to phone lines, but the magic of Ethernet is that you can do exactly what you propose. You’ll want a network switch (not expensive) as a central hub that you then connect to your router.
If you haven’t put ends on Ethernet cable before, it takes a bit of practice to get good at. Consider using premade cables or at least be ready to redo half of the RJ45 connectors you put on.

December 8, 2010Phone jack: Need help understanding what I'm looking at
It’s been extended to another location. Telephones work off of one pair (typically blue/white), not multiple like Ethernet. It looks as if the off-brand scotch locks are extending it over the orange/white pair. Pull all the wires out of the cavity and see what cables are going up, down, or sideways in the wall. It looks as if the green/white and brown/white pairs are already spliced together. If you want to get rid of the jack you’re holding in the photo, you’ll need to splice those two sets of wires together. I’d say cut them, but I don’t know where the orange pair goes, so you might mess up something down the line. More on reddit.com

r/nbn on Reddit: What is the wiring pinout on this telephone jack?
November 5, 2023 -
This is the main connection for FTTN. There are other telephone sockets in the house I assume are disconnected. Two sheaths come in. Both are 4 core red, black, blue, white.
On the right hand side is a yellow, white (2 of), and green cable. The yellow and green cable are both crimped to the fork connector but not stripped. The white wires are both completely oxidised and likely dont make a connection with the screw.
On the left are a red, black and two blue wires (one from each sheath). Only the blue wires seem to be connected to the screw. The black and red wire are crimped to a fork connected, but again aren't stripped.
Basically what I want to do is replace this socket for a modular one with an RJ12 for the NBN connection, and an RJ45 so I can run ethernet to the ceiling where I will install a switch. The idea is to pull the old telephone wires in each room and replace with ethernet.
I dont understand the pinout of the wires so Im unsure how I would reterminate the NBN connection to a new RJ12.
Inb4 "you need an ACMA cablers license for this". Lets just say its all hypothetical for educational purposes.
Thanks!

Just firstly the reason you should use a qualified person is due to the potential electrical hazards that may exist. But I get that calling somebody out can be expensive. Only one of those two black cables should be active. One will be left disconnected when you fit your new outlet. I also recommend you see if you are eligible for a free upgrade to nbn FTTP.

February 22, 2026 - Sometimes the same connector is used by different countries but wired in different ways. For example, telephone cables in the UK typically have a BS 6312 (UK standard) plug at the wall end and a 6P4C or 6P2C modular connector at the telephone end: this latter may be wired as per the RJ11 standard (with pins 3 and 4), or it may be wired with pins 2 and 5, as a straight-through cable from the BT plug (which uses pins 2 and 5 for the line, unlike RJ11, which uses pins 3 and 4).
