I just had a look in the basement of our building, and discovered this setup. Any one have any idea what it might do?

Lmao
Someone needed two plugs and had one cable, and no desire to get a switch it seems 😂

@Yamemori Yeah, probably. Doesn't ethernet require at least 4 wires?

Don’t think anyone in the building has a phone in their apartment. Plus I haven’t seen this setup before. I’m pretty sure the loose cables you see were connected at some point

It seems like someone is running 2x 100M lines through one cable

Its 4 voice lines. They didnt have a rj-45 mod plug for the last one so they used\cut old cable and crimped it together! LMAO sometimes you gotta do with what you got

Maybe alarm\phone lines? Its gotta gotta be analog with only one pair@ChainsawBaby

I figured out what that cable hack was. We are part of an experiment to reduce energy consumption from our heating, yet maintain a nice temperature in the apartment

So the company that's doing the experiment has 1 sensor in 4 apartments

And since we're using coax internet, they just plugged the sensors to the ethernet port in the apartment and then put the 4 sensors into one cabled stretched into the boiler room.

Mystery solved.
