House is CAT5 wired with a phone line. How to get networked?

My house is 10 years old and is completely wired with CAT5 wiring. There is a central punch block with all the wires entering. the phone lines work fine. I have a basement where the wireless connection is just horrible and am considering converting a phone jack to a network jack.

I pulled out the RJ-11 phone jack and found the brown and green twisted wires were free and the blue and orange were in the RJ-11 jack. I then placed the wires into an RJ-45 jack with a 568B configuration.

I was hoping to find the corresponsding wires in the punch block on the main floor of the house. I did find the wire, but it seems that there is one cat5 cable running into four different spots witht he blue and orange twisted pairs being used. If I pull these wires out to get the corresponding cables, then I will not have phone service to the other rooms in the basement. The brown and green twisted pairs are free and clear off to the side.

I am not really sure what to do.

Can the phone line and data line run through the same wiring? Will there be a conflict? Do I need all 8 wires or can 4 work for the data?

Right now there is an RJ-45 jack in the wall (the one I replaced) and if I plug an RJ-11 phone male end into it from a phone, there is a dial tone, so at least I have not messed anything up.....yet that is....

Thank you in advance.

Let's keep it simple.

You may use PAIRS to do what you want. If you steal a wire from some other pair you broke a rule.

cat5 wiring from phone to data

I may have figured it out now. There are eleven cat5 wires going into the punch block. The wires are all wrapped together like a big mess.

I just need to disconnect the one that goes to the jack that I have swapped out to be the RJ-45 jack. Once I do that, I can connect an RJ-45 female into the closet and there will not be any phone line and I can use all 4 pairs to connect.

The labeling by the installer was not the best. How can I test phone lines to staighten out the wiring?

Keeping it simple.

Use PAIRS. The test is visual. Is it a PAIR?

I believe I have it

Thank you very much as your advice to keep it simple is good. I believe that I can get all the wiring isolated and just use the two ends of cat5 wire. It has 4 twisted pairs and that will work fine.

Thank you for your help. The deciphering of the writing of the installer will be a challenge but doable.
