Hi all, I’m trying to run a Ethernet cable to my home office in a house built in the 60s. This connection is unlabeled and I’m not sure what it is. Can I somehow replace it with an Ethernet cable? I’m new to all of this and did some poking around in the sub but I’m not really sure what I’m looking at or what I’m in for. I don’t have any coaxial cables that I can utilize (unless they are hidden behind a wall? Any easy way to find those?). Thank you.

4 hours, is what it is. Possibly more.
25 pair Cat3 wire typically used on business RJ66 blocks for distributing phones. This case it looks like the possible main feed into the room for several lines. I would recommend replacement to a Cat 6 ethernet wire if at all possible. This will not work for internet purposes are any decent speeds.
350 max length of single run, CAT6 non-plenum Use attic space and basement. Buy fish rods/sticks and stud finder
You’ll probably discover only 1 or 2 pairs were ever used too. Telcos were notorious for putting in ludicrously complicated wiring for what was in reality a simple two wire analog circuit or two.
Future proofed for stuff that never happened or was just about making it look more complicated to justify the line rental fees.
Future proofing for when a pair goes bad they can cut over to a good pair.
Well, there was an element of that involved, but they also tended to just throw tons of spare pairs in with an idea that some future tech might use them. At the time PCM based circuit switched data was being developed and envisioned to launch as some point. It would ultimately launch as ISDN in the 1980s.
Local ISDN S-Bus wiring usually ran with two pairs and an additional two pairs for power. It was rarely deployed in homes, other than in a few European countries, but it (or proprietary versions of it) were commonly used for office telephone systems.
Rapid advances in multiplexing in the 90s saw DSL emerge as the most common way of getting fast data into homes and small offices. That only required a single pair and then telcos shifted to fibre to home. So it’s all redundant.
You’ll see plenty of home phone installations that used CAT3 or even CAT5 in the later days of PSTN with tons of spare pairs.
DSL/telephone wiring. It’s “daisy chained”. Blue white are the only ones actually doing anything.
You’re really not going to be able to do anything with this that will help with running new wiring. Very slim chance that is not stapled down somewhere inside the wall. Where are you trying to run the Ethernet to in relation to this jack??
That is a telecommunications artifact. You should put a picture frame around it .
If you do not have a land line phone or a security system you can get rid of it . Just tie a pull string on it when doing the demo work
Looped cat 3. I would just run outdoor rated ethernet on the outside or if you want to get fancy in EMT or liquid tight.
Old landline copper garbage not worth keeping unless you live way out in a rural area. It honestly would be easier just to tear it out and run cat5 or 6.

A damn shame, that’s what you have.
This is sin, many many sins covered with a faceplate.
Pots?
This is unjacketed 6 pair telephone wire. We call this particular type of wire “E Wire”. It’s a type of inside wire used for telephone service in houses and apartments in the 1960s and 70s. It’s probably original to the house. It probably runs through your attic, and dips down to your phone jacks in the walls. Not useful for much except telephone service. Anything more than that will need to be a “home run” from device to device.
I never knew that it had its own name, cool! I just know that I cursed every time I encountered it.
This is correct. Probably daisey chained through the house. If it’s an apt don’t cut it as it may be shared iw. If it’s your house only useful for telephone and dsl.
Just… put it back.
