Re: Uverse RJ11 Issue

The cable in question comes out of the wall and I'm trying to figure out which wires are the ones that should be in the jack. I m frustrated because I though copying the plug that I replaced would fix the issue. Can I look at the outside box to confirm which twisted pairs are used?

Regarding the quality of the connection, I've crimped it twice trying to get a good connection. Is there a way to test this? Can a voltmeter be used to check which wires are active?

Thanks for the responses.

Absolutely. Head out to the Telco box (aka NID) on the side of your house, typically by your power meter, with a flat head screwdriver. There should be a screw marked "customer access" -- loosen that, then open the door, and see what wires connect to the AT&T service entrance module.

If I had to guess, the wire pair is green/green-white. That is the de facto standard U-Verse techs use for the VDSL2/ADSL2+ (depending on flavor) data feed to the modem

If you need assistance identifying what is what @ the NID, feel free to take a photo & post it. And officially, leave the screws labeled "Telco Access Only" alone...

A little more information on NIDs: »AT&T Southeast Forum FAQ »NID (Network Interface Device)?

Thanks for the response. I posted the pictures a few minutes ago. You are exactly right, the pairs are green and blue. So I think the next step is to properly wire the RJ11. Do you where to find the diagram for the correct order for the pairs?

Thanks for your help.
