The Network Termination Device (NTD), also known as the nbn® connection box, is required to be installed to connect to the nbn® network. NBNCo installs the device inside your home, which then connects to your Occom WiFi modem. The nbn connection box takes the data transmitted from fibre optic cables and converts it to electronic signals that your router can use. In the case of nbn™ Fibre to the Premises (FTTP) networks, one NTD can support more than one active internet service. On the day of connection, contact our support team to assure that your connection box is activated and working.
