sharing phone and internet on cat5

My house is wired with cat5
Phone runs across pins 4+5
I'm trying to set up a network using pins 1,2,3+6
with pins 7+8 free

Can't seem to get it to work, any suggestions.
 
So you are running DATA and Voice through the same cable? Unless that is some high quality cable I would bet on interference from the voice...

Also could you post what you have did and what doesn't work about it?
 
LOL

Actually what is going to happen is similar of what would happen to the Heart when you pour too much BaconGrease into the human body. I.e. too much noise, and partial blocking.
 
HEY! What's wrong with bacon grease? If I didn't have my four eggs and half-pound of bacon every morning, I wouldn't want to live anyway.....😉

If the phone is on-hook, it shouldn't cause much / any interference .... but OH MAN! That ring voltage / pulses ... now that'll mess with data sumthin' fierce. Off-hook is not a good thing either. Unless you do it semi-perfect, you're likely to get some crap on the phone line too.

Voice/Data on the same cable is not recommended. It's REALLY, REALLY, REALLY not recommended.

But you'll do it anyway, so good luck to ya.

FWIW

Yeah, good idea but it's not gonna happen without lots of problems. Cat 5 is cheap so just run some more or just run simple phone wire.
 
Definitely try to run another cable for voice. But if that's not an option, make sure you're using wires on the same pair (i.e. orange-white, blue-white, and not mixing them across colored pairs). If that still isn't working, the polarity might not be right. Try switching the wires at either end.
 
Thanks for the replies... oh and there is medication for high colesterol so may as well indulge!

Every room in the house terminates in the attic on a punch down board.
the phone line runs through the blue/blue+white pair of wires on pins 4+5

I tried just plugging in computers in two different rooms but got nothing.
I've since isolated two rooms off of the punch board, separated the wire pairs (left the phone line intact), hooked this up to female rj45 connectors using pins 1-2-3-6 (pins 7-8 free) and then to the cable router on one end and a computer on the other. Still no go.

I'm thinking of disconnecting the phone line in those two rooms to see if the network will work.
 
Even if you have no use for them, you should still terminate 7 & 8 (the brown pair).

Good Luck

I was actually thinking of doing something similar at my house--maybe you guys can help me with this. My house is not that new (20+ years old), so I'm not wired with CAT5. But someone showed me a while ago--and it seems like a pretty good idea--how they used the second (unused) line running through their house to use as a data line (so I would run the voice/data on 2 separate lines). So I guess it would be the equivalent of CAT3 (only 10Mbps), but that should be sufficient for Internet sharing.

So say phone runs on the blue/white pair while the orange/white is free. So ideally, I could get a wall plate that has both a phone jack (RJ-11) and an ethernet jack (RJ-45). I assume the blue/white would go to the RJ-11 the way it's hooked up now. But what about the other pair? (There are 8 wires in the CAT5 cable, but there are only 2 for a phone line so I'm not sure how one would convert this...) And how would I get it so that the connections from each of the rooms ends up into a hub or my Internet router??

Thanks a lot for your help!
 
Granted if you have to work with someone elses wire job and not to thrilled about doing your own experimenting is fine and can turn out to work (even if unrecommended and could cause problems in the future)

But why would you plan to do it the wrong or unsupported way? If you are going to run new cable for any reason why not just run two cables and seperate the two? Data line is for data. Voice line is for voice.

Wouldn't that suck if all of a sudden Gigabit became cheap enough to run to the workstations and you would have to rewire your whole house because you didn't want to spend the extra few dollars to run a second line.

It will take the same amount of time to run but save you time / money / headaches in the future.
