They probably helped lead the local rollout.

No idea why so many people got their knickers in a twist in the other thread recently because someone got an ONT installed prior to ordering.
It isn't that unusual.

The other thread was a whole different story as the OP there wasn't making sense so was unable to explain what had gone on. Lets just drop the point about the other thread.

Oh sorry Dect, we've bought a block of flats of which we are now running and operating (recent new build 2018), and it is fully cabled with Openreach FTTP

Thank you for explaining, if its a block of flats then their must be other ONTs installed on site, are all the others showing the LOS light on? I'm trying to get my head around if its just one ONT or all ONTs

Yes so all other 'occupied' units that have taken up the Openreach service have had no issues as far as i am aware (all units have an ONT and BBU).

I hadn't realised a red LOS light even before a service had been switched on was a bad sign. I'll have to get my building manager to have a look into it, but we'll wait to see what the OR engineer says.

Lights on ONT as per Huawei description

PON-----LOS-----Description
=======================

Off-------On-------The GPON terminal is not connected to optical fibers or does not receive optical signals.

Blinking-Off-------The GPON terminal attempts to set up a connection with its upper-layer device.

On-------Off------- A connection is set up between the GPON terminal and its upper-layer device.

Off-------Off-------The ONT is disabled by the OLT.

Blinking-Blinking-The ONT is prohibited by the upper-layer device or blinks abnormally

In that case it sounds like the developer installed the ONT, but it's clearly not fibred up correctly because the LOS signal is red. This could be a problem locally to the ONT itself (e.g. fibre connector not plugged in properly), or it could be something missing or broken upstream.

I wouldn't worry about it: an engineer is booked, and it's their job to resolve it. At worst, if it turns out to be a major problem then they may not be able to resolve it on the first visit - but since this block of flats was planned and built to have Openreach FTTP then it should be fixable.

Is the developer required to do any more than run the basic cabling, power up and connect the ONT, maybe clean the fibre faces (if you’re lucky!) at the ONT? Doesn’t read like they need to do any more.

The summary is "red means dead" - either no light (or not enough) at the ONT. Call service provider to resolve.

So after a bit of digging after you guys flagged the LOS light being a significant issue, we had a bit of a play with things and found the ONT in this particular unit is not actually connected....to anything!

The fibre cable goes from the connectorised point on the ONT through the ducting behind the wall in the building unit, and just hangs limply inside it..

What do you guys suggest the best course of action to be? Is this one where we need to go to Openreach directly to ask what happened when they installed the fibre to the building or should we go straight to TalkTalk to warn them about our new order?

I'm actually not surprised in the slightest.

I would leave things be; you have an OR engineer visit already lined up as part of making the service active. The engineer ought to be able to resolve this on their visit, as long as they can get access to the appropriate spaces to run any necessary cable and make connections between the ONT and wherever the CBT is located.

I thought you already had an engineer visit booked for about 2 weeks time? Let them sort it. If that's not the case, contact TalkTalk to let them know.

Yes we do - I just wasn't sure if we should flag it in advance if this engineer was just thinking he'd need to turn on the service etc

Relax. It's the engineer's job to sort this, and plugging in the fibre is the easy part of the job. And if they break it, it's not your fault
