For some nbn™ connections there is no need to keep an active telephone service. The nbn™ network uses a number of different delivery methods, and the following list details the nbn™ technology types that use the copper line:
1. FTTN - Fibre to the Node. This is where fibre optics is delivered to your street and then high speed internet is transferred to a copper cable that runs into your home. The node is a box that is constructed in the street that transfer the internet from fibre optics to copper. If you have an existing copper telephone line connected to your property, nbn™ will use this for nbn™. Note that there is no need to continue paying line rental, you can opt to cancel the phone service after your nbn™ service has been connected.
3. FTTB - Fibre to the building. This is where fibre optics is delivered to your building and then copper is used to distribute high speed internet around you building. This is used in apartment blocks or shopping centres. The connection would use any existing copper lines but same with FTTN, you may cancel the phone service after you are connected with nbn™ if you do not wish to keep the phone number.
4. FTTC - Fibre to the Curb. Fibre optics is delivered connecting to a small Distribution Point Unit (DPU), this is usually located inside a pit on the street. From here, the existing copper network is connected to the fibre to form the final nbn™ connection. If you have a phone service prior to switching to nbn™, you would need to keep that until nbn™ is connected but you may cancel if you do not wish to port the number as nbn™ phone.
