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.
