Hi all, I've got the incoming black telco wire connected by electrician to a length of solid core cat 6 UTP down to my cabinet where I want to wire it with an RJ12 connector to plug into my router.

The electrician connected the incoming wires to the cat6 in following config...

(Incoming --> Cat6):
Black --> Brown/white
Blue --> Brown
Orange --> Yellow
White --> Yellow/white

Trouble is I can't find any reference to which of the incoming colours should correspond to standard RJ12 colours... i.e.

Yellow, Green, Red, Black.

Anyone familiar with that set of incoming colours?

Thanks heaps.
Jon

The incomeing cable from the chorus network should be 2 pairs: Older cable its 1:yellow/black & 2:White/Brown / Newer type its 1:White/blue & 2:Red/black. Normaly these pairs are connected (in a CAT5e or CAT6 etc) 1:blue/white-blue and if required 2:orange/white-orange. Just the one pr (blue/white-blue) is connected to an RJ45 socket, in which you can plug an RJ45, RJ12 or RJ11 for phone service.

BTW There is no Orange in a normal service cable and there is no Yellow in Cat6 - in saying that even if we substitute Red for Orange (in the service cable) and Orange for Yellow (in the CAT6), your sparky obviously has know idea what he is doing with the combinations he has connected together.

Ha yes he did say networking is not his area! ;) but yes seems what he wrote as incoming orange is red and quite right what he meant as yellow is orange on cat6

So to get my internet working tonight (my main priority) I should just connect the brown cat6 (through which running incoming blue)... into an RJ45 socket then run RJ45-RJ12 cable to the router? Just the one wire?

Was hoping to just connect RJ12 head direct onto the CAT6 cable?

Actually scrap all of that, I decided to get up in the roof to see what he's actually done and it's totally different anyway?!

The incoming cable is the older style pair you mentioned, Yellow/black & White/brown

Thos are connected as follows...
(Incoming --> Cat6):
Yellow --> Orange
Black --> Blue-white
White --> Orange-white
Brown --> Blue

So we just need to figure out which of the incoming colours above should be punched into which slots on the back of an RJ45 patch panel or faceplate.

Orange + White/blue will be the first pair. try that first.

If it was me I would redo that joint properly and put yellow/black on white-blue/blue

absolutly - it will generaly work for voice - not being on a 'twisted pair' in the Cat6 - but will cause problems with DSL being on split legs.
.
I have discribe this situaton to others as like haveing two pairs of jeans and wearing one on one leg and the other on the other leg - yes they may cover your legs but they realy dont cover the rest.

So you have a colourblind electrician who doesnt understand pairs.

What else did he do at the house you should be checking out?

I think there should be a law banning electricians from touching phone or data cabling.

There are rules to stop non people without their electrical ticket from touching power cabling because you "mightn't do things properly" and yet week after week electricians make a shambles of data and phone cabling because they have no idea of what they're doing.

I was working on a brand new apartment building in Wellington last week (it literally opened last week) and it has 2 x BT jackpoints wired in series in the apartment. I thought I'd gone back to 1994.

From my experience they should be banned from TV cabling as well, I have seen some shockers over the the years, wires twisted together i.e. no splitters.

I know enough to be dangerous

Yep, either that or entice them with Beer to training via their local wholesaler, seems to work.

Hey thanks guys for all the replies... so no joy yet, my main mission right now is to get our internet back on but I want to do it correct. I reconnected the incoming black/yellow pair to the cat6 blue/white-blue pair. In my cabinet I've punched down the cat6 blue/white-blue both into the back of an RJ45 connector as shown in photo below. (also tried into back of patch panel with no joy either). From the RJ45 I connected the RJ11/(12?) to the router as also shown below.

I also bought a master filter ( http://dynamix.co.nz/productimages/pdfs/xdslmaster.pdf ) and tried wiring the the incoming cat6 blue/white-blue into what it says should be the incoming line orange-white pair. Connected out using the green-white pair to modem as instructed on filter. Still no activity light on the router and I've been logged into the router polling for activity every 5 seconds and nothing showing for PPPoA. Any suggestions... have I got this all wrong still?

Thinking of calling on the services of coffeebaron instead! :)

surely you should be able to test with a phone to see which pair of the incoming has the dial tone? and then keep extending from there

No need to strip pairs to bare copper. You should just punch it on.

If yellow/black isnt live then try white/brown.

As for the splitter... don't really see the point if your service lead is connected directly to the modem. If you just simply need to filter off POTS then stick it on the end of the Cat 6. Connect blue pair of cat6 to orange pair of splitter. Then punch green pair of splitter on to rj45 for dsl and blue pair is for voice.

Chevrolux, thanks tried exactly that with the splitter but nothing. You're probably right I doubt I need it.

sbiddle / Jase2985 - We've just had a major renovation so no phones/lines connected... literally all we have now is this incoming black cable from the street with it's black, yellow, brown and white lines. I just tried the same config as in photos above with splitter sending blue/white wires into back of RJ45 and plugged a phone in but no tone.

I'm testing with two different RJ11 leads so hoping it's not just two dead leads after all this.
