Hi @Meredith That sounds correct, your Fibre To The Node connection will use your existing copper cabling into your premises, if you have'nt already, you should recieve a Modem/Router from TPG that needs to be plugged in and connected according to the diagram that will be packed with it.
You'll know when to plug it in because your existing ADSL and/or fixed phone service will lose connection before the NBN is connected. You should be notified via email and / or SMS when the new service is active.
