Update:

New civil work has been completed yesterday to replace the original fibre.

And today they have installed a (HUAWEI EchoLife HG8240) for the ONT which has a built in 4 Gigabit port router and two POTS lines.

ONT is not a router, its sort of a fibre modem. you still need to connect a router to the ONT

Look at the stats for HUAWEI EchoLife HG8240.

It's not the router - your ISP will provide you a router to plug into the ONT only 1 port will be live

the other ports are for other internet connections and things like TV

hamish225: the other ports are for other internet connections and things like TV

I'm just thinking here - To me that doesn't make sense.

If there is no internal IP (layer 3) routing, wouldn't the manufacturers have made it with one WAN port (fibre) and one LAN port, (as a bridge between the two networks systems).

What is the difference by pluging one of the other LANs into the ethernet port of the TV or into a computer?, both require an IP.
The ONT has only one WAN port (fibre), How can there be other internet connections?
Why would the manufacturers put in two POTS ports, if there is no internal IP (layer 3) routing?
Why would the manufacturers put in four LAN ports, if there is no internal IP (layer 3) routing?

It looks like DHCP on the ONT is disabled by default, so im guessing that a router from an ISP would have a static IP of (192.168.100.x/24) on the WAN side unless they change it on the ONT when they liven it up.

Although that would explain why people would think that a router is needed, since the ISPs are heavily pushing out routers to people.

An ONT is a pure Layer 2 device. There is no ip or dhcp service or anything. It takes the layer 2 signalling from the RSP handover and pumps it out the port your RSP has purchased on the ONT. So there isn't a built in switch in there as your RSP would need to pay for that.

Basically you need to plug your RSP supplied router into port 1 and then the router is where you get internet service from. Otherwise you would need to do PPPoE or just DHCP depending on the RSP on vlan10 to get things working and be assigned your Internet ip on your own device.

You seem a little confused by this, probably because you don't understand the OSI layer and keep talking about layer 3. A router is needed as the ONT is merely a layer 2 bridge. There is no need for any layer 3 features in the ONT and no requirement for it as Chorus and/or the LFC are only a layer 2 provider. Service for each individual port is delivered on a different VLAN from the RSP to the ONT.

The router from your ISP will have a full layer 2 connection back to your RSP on this VLAN and will use DHCP, PPPoE or a static IP to give you an IP address. The choice of authentication is solely up to the RSP.

Ok, What I meant was, why would the ONT have POTS ports that cant be used?

If its only a layer 2 device why would it have stuff that needs layer 3?

The only way I could see them configure it to make it a only layer 2 device is by bridging the WAN to a LAN port,
which in turn bypasses any extra features that it could offer.

Just an idea here, if its a layer2 device could the ISP not provide a virtual router service with DHCP, NAT etc. from their own equipment? Could be easier to manage?

suppose they could, it might be good for some people but not for those who want to manage all that themselves or have fancy expensive equipment they want to use.

The POTS ATA's can be used. They are delivered on a separate VLAN per ATA and there is a whole lot of fun getting them working. As depending on the LFC you configure them via your fulfil process or need to run a TR-069 as a rsp to configure them. They are not for end customer configuration they are managed by the lfc / rsp.

There is nothing stopping this but it would be a far than ideal setup for most people.

Like EUBA based ADSL2+ and VDSL2 and HSNS an ISP can do whatever they want with a layer 2 connection. This includes multi-site setups that don't necessarily even have a public IP address and can even be a large flat multi site network with a single DHCP server and gateway.

There is no such thing as a LAN or WAN port on an ONT. All ports are known as UNI's and have one (or more) E-AVPL's (VLAN) assigned to it which forms a layer 2 connection back to the RSP.
