Moving Phone Jack/Wire Splicing

Our cable modem, router, etc. is tied to a wall jack that is in a bad spot - I would like to move it. Access to the wire is easy, it is in our attic space. Comcast's contractor already spliced the section feeding the jack when they installed service years ago and it wasn't a pretty job. I am not familiar with telephone wires... they look like Cat 6 to me - can someone confirm this based on my photos?

Phone lines are/ were Cat 3. Ethernet wire is easier to find these days and will do. The twisting cuts down on interference.
 
It's unshielded copper wire . Not a very technical process to splicing it . :)
That is true only if you’re using the wire for tone. If you’re using the wire for internet modem connectivity, in home networking, et al, it matters a lot.
Each strand of the twisted pair has different twist rates that correspond to each pin of your RJ45 modular connector. This helps eliminate cross talk by creating its own “shielding” regardless if its terminated using a T568A or T568B wiring scheme.

And to the OP: This is the perfect time to upgrade your cabling to a more modern spec and topology……Just saying ✋😎🤚

That kind of looks like a mess.

As has been said if it's normal phone wire for RJ11 jacks it does not matter much.

If it's network cable then you never splice it. You typically put a RJ45 connector on each end of the wire and use a female to female coupler.

You NEVER untwist any more of the network cable than is absolutely necessary to get the RJ45 connector on.

If you have never done any RJ45 connector crimping then buy a decent crimper, some RJ45 connectors and several feet of network cable and practice. And practice.

Passthrough connectors are much easier but the crimper is more expensive.

Also handy is the outside jacket stripper. It's got a round blade in a hole and your twirl it around a few times.

After your done you need a Fluke network cable analyzer to check the network cable and connections to see if it meets the specs. That's $2000.
