Phone jack mess, please help?


First, I really hope that this is the right place for this, if it's not I'm very sorry. I'm supposed to instal a new internet router tomorrow, one which, apparently, runs through my phone line. That's well and good except I've never had a phone in this apartment before, and the phone jack was removed and hidden behind a mirror because it was bulky and ugly. Now I'm trying to put it back together and am rather boned because it does not seem to match the diagrams I have seen online.

There are two screws with cables attached, but four places for screws to go. The screws with cables are both red and white striped. There is a blue cable, but no screw with a blue cable, etc. I'm a little overwhelmed and was wondering if anyone had any experience with this kind of setup or could point me to a tutorial involving it?

Any and all help is very appreciated.

A single phone line uses two wires. It used to be red and green.
Wire colors have changed as of several years ago.

If your internet SP is doing the hook up the installer will probably need to
Check which are connected to the phone utility box outside.

One of the twisted pairs will be used. Likely the red/white or orange/white.
One color goes to the red screw, the other from the same twisted pair goes to the green screw.
Its difficult to tell from the ball of wires there

Obviously you wont be able to test the line until the util co turns service on for you.

BTW, the internet that goes thru your phone line is DSL.

They will not be doing a hookup, I'm doing it myself, which is why I need help figuring these out. :P I did not expect this mess, so please bear with me while I ask stupid questions. :D

The only "Twisted pair" that I have are two identical pairs, maroon and white striped, each wire pair is wrapped around a screw. If I'm reading your reply correctly (see? Stupid questions) then one of these will go into the red and one into the green, the other two slots are left empty?

Thank you again.

A twisted pair will usually consist of a primarily colored wire with a white stripe and a primarily white wire with a stripe of the same color...ie red with white stripe/white with red stripe.

One of those would go to green, and one would go to red...NORMALLY. I have found with phone wiring, there really is no standard anymore.

So long as only two screws need to be screwed in, not four, I think I have enough information to tackle this beast. Thank you both very much!

the general rule is:

old way -
line 1 - red and green
line 2 - black and yellow

new way - blue is the new red, blue/white stripe is the new green

reversing polarity will cause inconsistent operation

that is a huge mess. not sure what is going on there.

i have done lots of this wiring in my house and hooked up my share of dsl modems. worst case use trial and error. if you can see what is connected at the network interface it would save you huge time

It looks really horrible, but it seems like the only wires that are actually connected to anything are the four maroon and white ones. They have the ends stripped and are wired to screws. All the other wires end in a coating or are in a plastic nib.

Old way vs new way and the reversing polarity comments are very helpful, sounds like I just need to trial and error it. Thanks!

It's very likely that the wires connected with the white crimp connectors will be the phone lines you need to use. Those connectors are used by the telephone company....not the nuts and bolts you see. The Blue wire will terminate with the red wire connectionn of the jack, the white/blue wire will go to the green. No offense, but you need to get some help here.

Normally some of the apartment do have pretty large phone bundled conductors some case I call them 5 pairs or 10 pairs either two is pretty common set for small to med size building.

I betcha that just go to the demark box aka main termation box for the phone system and you will have to look for your pair where it will show up with it.

One serious warning here do not try to interferince other apartment phone system unless you get someone get ticked off ( I have see it happend before so I give them a head up if have major issue )

Normally Telephone tech or internet tech will able sort it out very fast with proper tools and they will know which pairs to hit.

By the way with DSL system you will need minium of two pairs or more on phone line so be aware with that.

The way I look at the photo sound like Brown et White with brown stripes is your set

How many other apartments in this building ??

Merci,
Marc

I wanted to thank you all for your time and advice, the update is that I got it all reassembled on my very first try! The brown/maroons screwed into the red and green sockets and everything went off without a hitch. Figuring out how to get the wall mount to screw in properly turned out to be more of a challenge than the wiring itself! Thank you all again... and frenchelectrican, it's a very old apartment complex with less than 100 units, very good guess!
