Incompatible Hardware
The following list shows you which devices you can & can't connect to the NBN Co NTD
This includes connecting directly to the device, or via internal cabling. This list is not exhaustive, but should give you the general idea of what you can & can't connect.
Telephone Handsets
- The telephone handset you use must be compatible with tone dialling only.
- This rules out any old devices like rotary dial telephones.
- Handsets with a pulse/ tone switch, set to tone dialling will also be fine, although we would recommend that you upgrade to a more modern device.
- We provide the telephone service via the UNIV port of the NTD, which means that it is not compatible with VoIP ATAs (& nor do you need one)
- The telephone handset must have a standard RJ11 type connection.
- This rules out PBX type handsets & IP handsets as they normally have an RJ45 connection or a 6 pin plug.
- The maximum number of handsets that can be connected to the NTD via the UNIV port (& internal wiring) is an enquiry we have made & we are waiting for an update on this. As a rule of thumb, until we do receive confirmation lets assume that the maximum number of devices that can be connected via cable to the UNIV port of the NTD is 3.
- Fax machines are suitable, provided they fit the criteria above.
- Alarms are also suitable, provided they fit the criteria above.

Tone dial vs Pulse dial - how can you tell? Regardless of the style of handset you have, if you phone goes "tic tic tic tic tic" when you dial, it is pulse dialling & is not suitable. If your phone goes "beep, boop,bip" when you dial it is tone dialling & is suitable
Modems & Routers
Our Data connection provides you with data over one of the UNID ports of the NTD.
- You do not require a modem at all, in fact you can connect an ethernet cable directly via an RJ45 cable directly between your computer & the NTD & be on-line.
- If you do need to connect multiple devices you can use a Router or a Switch - as long as the device accepts incoming connection (WAN) via RJ45 Ethernet.
- You can also connect up a Wireless Router. Again it must be a Router, not a Modem/ Router - that is, it must accept incoming connection via an (WAN) Ethernet Port.
- Most Modems & Modem/ Routers will not be suitable, because they accept the incoming connection from the outside world, via a telephone connection using an RJ11 port. (sometimes marked as ADSL)
- Some Modem/Routers have two methods of accepting an incoming connection: #1. via the telephone port, & #2. via what is called an EWAN port - which is simply an RJ45 port that can be changed in programming to accept an incoming connection. These are suitable for use.

The Wireless Router to the right is suitable for NBN connection to the NTD. (right) --> The Ethernet cable connects between the specified UNID port on your NTD & the BLUE port on the router. The yellow RJ45 LAN ports are for connection other computers & devices |
