How good are the OR ONT? I've never had any half decent equipment for "free". I am wondering if there is any alternative. What happens if it goes faulty? It's different from a master socket, because there's a lot more to go wrong. I suppose it's more like the box I had for ISDN.

They're fine. You haven't any choice regardless. If it goes wrong Openreach fix it or replace it. I've had precisely 1 fail to date in all the installs done, it was replaced the next day.

The ONT is manufactured by Huawei. The service is locked to the serial number of the ONT. It cannot be changed unfortunately.

They also use Nokia (and someone else I've forgotten).

It isn't impossible that in a few years time there could be an equivalent to 'wires-only' for fibre, as has happened for ADSL and FTTC previously, but for now the demarcation point is the ethernet socket on the HG8240/HG8110 NTE.

I hope it never happens. It's better as it stands.

"Wires Only" for VDSL was a mistake. Ethernet as the point of interface is a much better idea.

Adtran

Plus the legacy ECI stuff.

Have they actually rolled out Adtran stuff anywhere yet?

I haven't seen any mention of them anywhere other than the deal being announced.

We are having to use our first application of FTTP (for business), we currently have about 50 DSL connections around the country so have been doing a little research.

We would like to replace the ONT with our own equipment for two reasons;

First. Our sites are remote and require an internet connection to operate, so we have been routinely replacing the modems that come from the ISP with enterprise level equipment for reliability. Our experience with provided kit is that it requires resetting more often than is good. We have failover lines and other mitigation, but it can still be a pain in the neck.

The second reason is related to the first. If something fails on site we need to replace it quickly. Rather than being able to do this ourselves, instead we have to go through the whole faff with Openreach just so someone can turn up and replace a box which we could have done a week earlier. It's not as if it saves a journey as Openreach won't enter an unattended site so we might have to drive from Somerset to Liverpool to wait for an engineer to spend three minutes unplugging and plugging in a piece of equipment and driving the four hours back.

Hopefully this won't be a major issue! We will need to pay for two lines so we can remotely switch between them to maintain connection, which sort of defeats some of the advantages of FTTP.

As an aside, and talking about the ONT provided, the local fibre network would see all the traffic in your area, I am given to understand that if you take your ONT and plug it in next door you will still get your connection. So hopefully the security is good on them.

Scratch the earlier reply. Having properly read your post I see you're in the UK.

Simple answer is that all networks here will wholly provision and support the ONT. You cannot replace the ONT with a device of your own choosing. It simply does not work that way in the domestic FTTP market. Operators in other countries may do it differently, but not here.

Your handover point will be the ethernet interface on the device. Some Altnets, outside of Openreach will provision a combined ONT-router, but this is network specific.

Downstream shared bandwidth on GPON is encrypted. Return traffic is based on managed timeslots, as dictated by the OLT and ONT handshake. Its a fairly robust well established protocol. On-net protocols are well established for rogue ONT attacks and the like.

There was an article earlier this year saying Openreach had deployed Adtran and the first customers were live, that quoted Towcester as the first location.

It would be interesting to know how Openreach are getting on as the Adtran is a very different beast to the other systems they have. Disaggregated software defined platform vs. big old school systems for Nokia and Huawei.

So they have:

Huawei and ECI as legacy/not actively rolling out and
Nokia and Adtran as the go forward plaforms.

I have seen reports saying they are now deploying different vendors ONTs on at least one of the old platforms. Nokia on the Huawei maybe?

So there are four different vendors out there and interoperability is a pain so I can’t see them opening it up to third party ONTs for a while/if at all. The device serial number is locked to your account, they scan it as part of the install process.

Outside of Openreach CityFibre have Calix, so there are at least five G-PON suppliers out there in the U.K.

Yep think it was APTMAN on here that recently had a Nokia ONT installed oh a Huawei headend.

There's several other ONT vendors being used by Altnets here; Altice, Genexis, HALNy, Zyxel even TP-Link combo WiFi router/ONT by Hey! DKT Comega also figure highly in the Point-to-Point FTTP market
