How can I eliminate alternating dial tone and static in an added-on phone jack?

Question

I had a phone jack added in our house and the electrician who did other wiring for us a couple years ago ran a Cat-5 cable from the attic to the new phone jack The existing phone wiring in the attic is 4-wire and each wire is thicker than the wire in the Cat-5. I was unable to spice the wires together using compression splices because of the difference in wire sizes. So I cut into the existing wire in the attic, installed a phone jack there, and connected the Cat-5 to the phone jack.

When using a phone off the new jack, I hear a dial tone and static alternating every few seconds (tone/static/tone/static), and the same is true when I plug the phone into the jack in the attic. The person on the other end can hear me fine without static, but I can barely hear the other person. The other phone jacks in the house work fine.

We have DSL with a filter that's in the wiring that's plugged into another phone jack.

Any suggestions? Thank you.

Answer 1

did you strip the wires should make sure dialtone is on green/red on the old wire the cat five wire color code is diff.if the cat 5 wire doesnt have green/red in it ,then the color code is as follows use the white/blue for the green and the blue/white for the red the green and red on the jack face is all that needs to be hooked up

the DSL theroy is plausable... if you are not testing this with a DSL filter on your line, then the DSL may have gotten disconnected, and every few seconds you will hear the clicking and DATA of the DSL modem tring to restart or reestablish its link...



you dont need to move the DSL jack.. just test this with the DSL modem OFF... if the trouble goes away, you have a defective filter, or the filter is not connected properly..



using a jack to splice 2 wires together is IMO the best way to bridge 2 or more separate wires... but, if there is any possibility the pins may damage, or become affected by moisture, disconnect the green/red going to the jack pins....



IF the static still exists with the DSL modem off.. but you are only experiencing this at these 2 locations, (i assume the attic is feeding the cat5) then you need to find the other end of the older wire, and test from there... that wire going to the attic may need to be replaced..

the problem may be your DSL. we had problems when we used to have DSL. we ended up with static and a party line. try changing your DSL to another jack. see if that helps. good luck
