Fibre to the Premises and Fixed Wireless ports explained
Last Updated: Sunday 14 Sept 2025
Both Fixed Wireless and Fibre to the Premises have UNI-D ports in their Network Termination Devices (NTDs)/NBN connection box.
Fixed Wireless NTDs and some FTTP NTDs have 4 ports on the underside labelled 1-4. Your internet service is connected to just one of these ports (you can have other internet services connected to another port).

Important information for FTTP services
Your NTD may also have UNI-V ports in addition to UNI-D ports. These are used to connect telephones and can’t be used to connect to the internet.
To access the ports, you may need to open the plastic case covering the NTD. Simply unclip the cover using the clips on the bottom.
While the 4-port FTTP NTD can support multiple services, there are limitations as to the total speed it can support:
Older model 4-port NTDs can only support one 1000Mbps service at a time. That means if there is already a 1000Mbps service on one port, you’ll need to downgrade or cancel it to use 1000Mbps on another port.New model 4-port NTDs can support a maximum download speed of 2200Mbps combined among all the services it has. That means if you have a 2000/200Mbps plan, and wish to have a second service from the NTD, it will need to be 200Mbps or lower.
We will inform you which UNI-D port your Aussie Broadband service connects to during the connection process.
To connect your router to the NTD, run an ethernet cable from the correct UNI-D port to the WAN port in your router.
To configure your router, read our settings guide.
