Network Termination Device (NBN)
A Network Termination Device, network termination, or NTE is a customer-side network interface device used by the Australian National Broadband Network. Network termination devices provide multiple bridges for customers to access the NBN. There are different types of NTDs for the various connection technologies encompassed by NBN. All connection types except FTTN use NTDs on premises. Depending on the kind of link, NTDs typically provide two telephony and four data channels. An external power source is required, and an uninterruptible power supply can be used to maintain connection in power outages. FTTC requires power to be provided from the premises to the kerb.
NTDs provide user–network interface connections for connection of in-premises devices. They typically have multiple RJ45 jacks for the UNI-D connection, and some models have RJ11 jacks for the UNI-V connection. All NTDs are capable of passing VoIP traffic. FTTN requires premises to have a compatible VDSL2 modem. Each UNI-D port can be activated by retail service providers for different NBN services. The NTD cannot be used as a Layer 3 router for in-premises networking.
Most devices used in NBN are produced by Alcatel-Lucent, currently a division of Nokia Corporation. In FTTC networks, the hardware from domestic manufacturers CASA Systems and Adtran are used, and in HFC networks from Arris, currently a division of CommScope. FTTN networks, based on VDSL2 technology, can be accessed with any compatible modem or router that supports VDSL2. NBN itself doesn't sell any VDSL2-compatible hardware and it must be supplied by end-user of the network.
The network termination used in the specific case of an ISDN Basic Rate Interface is called an NT1.
In 2025 a new series of devices was released for the 2gbps upgrades for the FTTP and HFC networks. On the HFC network the new NTD will be an ARRIS CM3500B/AU. There will be at least two FTTP models, one being a Nokia XS-010X-Q with a single service port capable of up to 10gbe symmetrical speeds, and a larger 4 port device from Sercomm capable of sustaining 4 individual services that is intended for business and multi-resident properties.
The NBN have also used the Nokia U-010Y-A for testing and display purposes at the NBN Discovery exhibition area at the NBN Headquarters in Sydney. This device is capable of 25 Gb/s symmetrical speed using 25G PON with two SFP28 ports for the incoming and outgoing connection.
