To revert to very old terminology, "trunk". Eg: once you have connected 
the homes in Tamworth, you don't want them to be stranded on a purely 
local network. The "backhaul" provides the long-distance connection.

It was decided very early that NBN Co would *not* build backhaul - this 
would compete with Telstra, Optus, AAPT, NextGen and others that own and 
operate backhaul. So NBN Co will rent  backhaul from existing owners.
