Archaic phone wiring or Archaic Ethernet?

[cooldude8530]

Okay so i had an idea to re-wire some of my old dsl/phone wiring as Ethernet wiring, for its purpose i had no need for speed so i was not really caring on that front, but when taking sockets off i found what you see in the images bellow, it looks more like some archaic form of Ethernet. I may be wrong, infact i probably am but i am more so now looking for a second opinion.

That just looks like old phone wiring.

Definitely phone, as you can see someone has tapped the center two wires to go to another outlet. Those are the only ones needed for a single phone line.

If it's CAT3 wiring, that's rated for 10BT but can run 10/100 easily enough at short enough distances. You only need 4 wires so can still use 2 for the phone like so:

More important would be where the other end of the white cable goes. If these cables do not all end in a central location you can't really use them. Phone lines tend to be daisy chained together. Ethernet is point to point with a say a switch or router on one end the pc on the other.

You are going to have to remove/replace those jacks anyway, those look like UK versions of phone jacks.
