Topic # 113995 4-Feb-2013 14:45 Send private message

I have sucessfully wired my own home for data/voice distribution using a vdsl splitter and phone/data module which distributes the signals via RJ45 jacks.

I am in the process of helping out a friend who is doing a similar thing but without any phone module.

What I am planning on doing is running direct from the demarc point using one pair of a Cat 6 cable and into a vdsl splitter.

My question is once I go from the splitter I will have two pairs to connect, one for the voice and one for data.

Which colour pair in an RJ45 plug carries which signal?

I am assuming it can only be 1 pair for each as that is all that comes out of the vdsl splitter, but which colours do what?

Once I know I can terminate the connection using gel filled joiners and then run it into the back of an RJ45 socket and onwards from there.

And this one helps if you have different standard wire colours to connect to.

Blue is the center pins of an RJ45 so send the voice down that you anything you plug in will get the phone.

chevrolux: Blue is the center pins of an RJ45 so send the voice down that you anything you plug in will get the phone.

Yup the blue pair carries modem/phone signals on normal RJ45 outlets so, assuming the modem and phones are all at different outlets, you just connect those to the outputs of the splitter. If you do have to put phone and modem on the same outlet (or sharing the same cable) for some reason then you need to borrow one of the other colours to feed the modem, which means the second pair goes to the blue pins of the modem outlet. Better way is to run an extra cable for the modem or just park the modem next to the master filter and feed ethernet to the outlet (100 meg ethernet uses orange/green wires if you have an RJ45 splitter on the outlet).
