I've just read chapter 6:
Ensuring-ubiquitous-backhaul-availability-NBN-Implementation-Study-report

This discusses various options and there are a number of recommendations 
re backhaul (starting at recommendation 46).

I find it interesting that the implementation study uses the 
NBN_Reference_Architecture_Release1_Jan_2010 which only has one use of 
the word "backhaul".

I really don't understand the relationship between the "National 
Broadband Network Reference Architecture High Level Architecture Options 
for the NBN" and the implementation study. There seems to be a bit 
missing - the selection of options from the architecture paper.

The implementation paper still has an awful lot of options in it and 
there's no clear definition of how the whole system will hang together. 
The emphasis is on the costs of particular parts, not system structure.

I'm still confused.
