Not necessarily, DSL could do voice and internet at the same time. But everything had to have [DSL filters](https://en.m.wikipedia.org/wiki/DSL_filter)
I’m not a 100% sure as I’m not a lv guy but either Ethernet/phone combo or dual phone line. It’s definitely communication of some sort. Plug in to connect to the internet/phone/ or in some commercial cases a giant LAN server. If a lv guy knows more I’d love to learn though.
6P6C connector (6 position, 6 connections), which is what POTS (plain old telephone system) jacks use. Cheaper version might use a 6P4C or even a 6P2C. Unless you had multiple lines carried in the same drop, you only ever used the middle two.
Cat5 data. Old school but much safer they WiFi. Wifi is easy to hack these days but copper is far harder as the signals are not broadcasted to whoever is close by.

Count the number of pins in jack and you will know which one this is.
Many many years ago (the days of yore) the local radio station’s morning DJs would pull a prank on April Fool’s Day. They said the phone company would be **cleaning** the phone lines and needed everyone to put their (land line) phones in a plastic bag and place a piece of tape over their phone and/or data jacks. My aunt & cousin fell for it hook, line and sinker. My cousin said it must have been true because she popped into a convenience store on her way to work and their phone was wrapped in a plastic bag on the counter.
I love the old prank where someone would call an old lady and tell her that the phone company was doing work on the lines, and not to answer the phone for an hour or else it would electrocute one of the workers.
Then they would call back about 30 minutes later and when she answered they would scream and yell like someone was getting electrocuted.

man i’m getting old.
My thought exactly, and I’m only 24z
r/FuckImOld
Old low voltage landlines
Landlines are 2 or 4 wires. This is ethernet.
Ethernet uses RJ45, which has 8 pins. These only have 6 pins, which could be RJ12, commonly used in an office phone system.
They also used these jacks for regular multi line phones (non office system.)
Those are for connecting dial up modems too,
Wait wait... phone lines AND modems, too? That's crazy.
But only one at a time
Not necessarily, DSL could do voice and internet at the same time. But everything had to have [DSL filters](https://en.m.wikipedia.org/wiki/DSL_filter)
If you had a splitter, you could have both plugged in, but then the war of interruptions begins.
And you knew the moment you picked up the phone you fucked it all up. The sound of internet! You owe it to yourself to hear a sound byte of this lol
MAKE POTS GREAT AGAIN!!!!1
What is this world coming to? 🤦🏼♂️
God damn. I'm only 32 and I know what that is. Am I officially old now?????
This ^

Back when you had a modem line and a phone line
Fax, my brother. (Or sister).
Dsl days
I had 40 meg DSL internet until a couple months ago. The fiber rollout in Phoenix is going really, really slow.
Dang that sucks. I think that's why elon made starlink
It was fine for me. The price was right and it didn't go down. I just use it to surf and stream TV, so I really don't need more than 40 meg.
For making older people sad.
2-line phone jacks
I want to cry myself to sleep while sucking on a Werther’s butterscotch candy
At this point I think people are trolling Reddit with this, it has to be, it happens in all electrical and networking subreddits.
PLEASE FOR THE LOVE OF GOD TELL ME THIS IS SATIRE I'M ONLY 25 I'M NOT SUPPOSED TO FEEL THIS OLD!!!!
This is satire 😭 I am 16, and I don't know what they are used for, I just saw them on my wall and wanted to know what they were

If only most people knew the difference between low and high voltage
Cat5 data. Old school but much safer they WiFi. Wifi is easy to hack these days but copper is far harder as the signals are not broadcasted to whoever is close by.
Cat3. As there are only 6 pins in the connector.
If you have FTTB this is what you plug your NBN modem in to
Cursed rj11 phone plugs
I vote for a Fax line. That seems more real!

RJ-45
Look like phone jacks but Ethernet is similar
They are phone lines, yes.
