Looked inside a friend's Network Interface Device box on the outside of their house last night to see what wires were left connected after this past week. They got rid of their AT&T landline and switched their existing DSL service to a stand-alone / dry loop DSL setup.
In their NID box outside, they're left with the blue-white wires connected to a jack and no other wires are connected.
With this in mind, can anyone tell me what the exact situation should be as far as them connecting their Ooma Telo to a jack inside their home to provide whole-house service to all of the jacks throughout the house? Should it just be a matter of connecting a phone line between the Ooma Telo and a jack? Would they need a DSL filter device between the phone line connection between the Ooma Telo and the phone jack on the wall? Would they need one of those other devices that splits a line between L1 & L2? I'm just making sure I'm clear on all of this and I/we don't damage their equipment by not connecting something correctly.
