Pedro, my understanding of FTTN and copper the last mile is that the old phone service will continue to coexist with the new service for a period of time (18 mths) after which it is simply switched off . The new service (NBN) then is the sole user of the copper. The copper is not actually removed as it is used by the VDSL modem. Those that have not switch over to NBN by that time will not have any service at all. FTTH is obviously different as there is no sharing of infrastructure between the old service and new (fibre all the way).
