Australian NBN Co

It’s still a long way out and a lot can go wrong between here and there, but I thought this might interest a few of you.

NBN Co intends to build a GPON (gigabit passive optical network), providing Layer 1 and Layer 2 of the network, leaving layers 3 and above to service providers. In other words, NBN Co wants to offer very little more than the most basic physical layer - enabling service providers access in such a way that it almost feels like they are using their own network.

Quigley said he would expect the NBN Co's domain to "end at an Optical Network Terminal (ONT)... on the side of the house.",quigley-offers-isps-a-rough-sketch-of-nbn-architecture.aspx

Kind of curious why they think the ONT will need a POTS connection, surely anyone offering POTS can just provide an ethernet enabled ATA as a separate box?
