said by Michieru2:I never heard of such a setup really. All home wiring setups have a individual cable all going to the NID.
Sorry but that is just wrong ("all home wiring setups").
Are you saying each jack in your house has a separate cable that is run back to the NID? If so your NID must be significantly different then mine and must have many more cables going into it. In my house all the jacks are daisy-chained together like a Christmas light set (like in your setup 2 diagram), I assume this is just cheaper for the builder (less wire to run).
said by Michieru2:So if you said you where able to achieve dialtone on all your lines then somehow all these cables are somehow connected.
I can't imagine a phone configuration in which all the phones jacks are not all interconnected at some point. That's the only way it can work, otherwise each jack would have its own separate line.
said by Michieru2:Anyway setup 1 should be from a standard POTS. The idea I am getting of your setup is second one.
Your first diagram looks like you have all the jacks run back to a central place where they are all tied together and that in turn is connected to your NID by a single cable (which is different from every jack being run back to the NID, your earlier statement).
Regardless of how they are tied together (either of your two diagrams will work), if you disconnect all house wiring from the NID and leave all of the jacks interconnected then you can do what I said (connect the ATA to any jack and all jacks will work). If you look at from an electrical perspective this should be obvious.
