Does a master and slave telephone jack matter anymore?
I have never seen a wiring layout like the flats we currently have. A few years back we disconnected all the phone plugs and wired up a pabx system. Now i am wanting to switch it to voip and my question is about telecom telephone wiring.
Basically, can I wire my voip ATA into the back of a slave socket and disconnect the line to the road in the demarc box?
I remember being told that you dont get ringing on slave telephone jacks if you dont have a master in line first, but am wondering if this has something to do with older 3-wire systems where the master acted as more of a converter, and the capacitor circutry took the 3rd wire's voltage and added it into the 2wire system for common 2 wire telephones to use?
I do know that the demarc box on the side of the house has some circutry inside that looks like it is similar to a master socket without a plug- but this circutry is not connected to the auctual wiring.
