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