To throw in two cents from my experiences/observations... The ONT box provided (for Hamilton area) by Tuatahi First Fibre (formerly Ultra-Fast Fibre) was a Hauwei EchoLife HG8240H. Probably bulk purchased in their thousands prior to the 5-Eyes anti-Hauwei campaign was launched. As well as a Fibre port it has 4 x Ethernet RJ45 Ports at 1Gb/s each and two RJ11 telephone ports. You have to provide the electrical power to run the ONT box. Some models of ONT box have a port to plug in a battery backup unit to continue to provide you with an internet connection when there is a power outage to your house. As an aside... remember the old days of household telephones and how the phone company provided the 48V DC to make your phone operate. When you had a power outage you could still make phone calls. What an amazing design concept / service provider! On the outside of your house is a External Termination Point (ETP) box. This does not require any electrical power. This is where what appears like one fibre optic cable arrives from a Tuatahi distribution box somewhere in your street. The cable contains two fibre optic strands, but only one is used. I.e. Both transmit and receive is done over the one fibre optic strand. From the ETA box on the outside of your house, to the ONT box inside your house a robust form of dual fibre optics cable is run through your ceiling and inside your walls, etc. Again only one fibre optic strand is used. The ONT box has a web-based set-up and configuration. E.g. See this service manual https://www.manualslib.com/manual/1144404/Huawei-Hg8240.html . Theoretically you should be able to log in and manage the ONT box by entering 192.168.100.1 into your browser and entering the account and password. However the ONT box is always the property of Tuatahi and I suspect you will find that they don't hand out the password. The ONT set-up in NZ is designed for one house to have 4 x bedrooms and 4 x flatmates. Each flatmate uses their own ISP (E.g. Spark, Vodafone, Orcom, Skinny) and has been provided by their ISP with a router/wifi to locate in their bedroom. They run an Ethernet cable from their ISP's router to the Tuatahi ONT box and plug into their allocated port of the 4 x LAN ports on the ONT. I recollect reading that the HG8240H ONT box allows receiving/transmitting data over the fibre at about 3Gb/s. In theory all 4 x Ethernet ports could be transmitting/receiving at 1Gb/s. But then the maths doesn't add up and the fibre is the bottleneck and falls short by 1Gb/s. Thus in a four flatmates scenario they theoretically don't all get 1Gb/s, but with a three flatmate scenario they should all be able to stream simultaneously at 1Gb/s. However, as we move to HyperFibre and 8Gb/s then better performance ONT boxes are a requirement. Hauwei and other ONT manufacturers, don't limit themselves in their ONT designs to just catering for the NZ 4 x flatmates/4 x ISP's market. In another country you might have an ONT box that includes a router providing all the Ethernet and wifi for your home. This avoids the need to waste power and desk space on an ISP provided router, which also doesn't have battery backup. Using such an ONT box in NZ would effectively make Tuatahi the only necessary ISP and the other ISP's would not be required. Oh dear, shock / horror, we couldn't have that! I have seen documentation that shows a single computer set-up directly connected to the allocated Ethernet port on the ONT box. It's just when you need a local LAN with more Ethernet connections and wifi, then you need the ISP provided router. So, I believe your ONT can go directly to a PC provided this link is using PPPoE, and this PC can then provide the routing and wifi for your home, and thus avoid the need for an ISP provided router. E.g. Install OpenWrt (x86/amd64 version) on your PC. See https://openwrt.org/docs/guide-user/installation/openwrt_x86 . Run your PC and the ONT off a battery backup unit and you might actually be able to keep going when the power drops out. cheers, Ian.
