[LINK] NBN and the last 100 metres

Below is my understanding:
There is plenty of info on the NBN CPE (called an Optical Network
Termination Unit or ONT).
It can live inside, or outside, like a meter box.
It will be installed wherever is sensible for the premises, which will often
be where the main Telstra jack is.
It will present two POTS ports and 4 Ethernet ports, so you will have a
degree of flexibility in how the internal cabling works.

I understand there will be reuse of current ducts where that is possible,
and where trenching is required, it will be carried out by NBN Co
contractors. I believe they are using directional drills to get under
footpaths and driveways to minimise disruption (ditch withes?
