I just recently switched from Cable to DSL now there's no dial tones on any phones and it seems the problem is at the NID box outside is there somewhere online I can get a diagram of the proper wiring? The phone company are the ones who messed it up and they want $71.00 to come out and fix it.

I need to install the DSL line and put a filter on the phone so it doesn't cause noise or affect my internet performance

Thanks.
