Red PON Light?

Evening all,

We've hit a Red PON light with out Nokia ONT, but there is no LOS light on it.

Before i give TTB a call, do you know if theres anything obvious i should do?

Call TTB and report it would be my advice. There is nothing as an an end user you can attempt/do other than perhaps power cycling it.

Spoke to TTB Support - They suggested a power cycle, but not to avail either. They're going to book a fault in with OR, so will see how far we get!

Ah yeah I recall you posted about booking in a new service activation.

When did the service go live? Sounds like they might need to swap out the ONT if it’s faulty. Not quite a fail out the box, but near enough.

Yes that's right - It went live on Tuesday. It was an Openreach bod who came along and commissioned the ONT with the dangling connector that was behind the wall space, only took him about 2.5hrs to get it all up and running which i was impressed about.

We've had a pretty stable connection according to my team who utilise the service, until i went into the office this afternoon to see it not working!

Hopefully we can get them round asap (not sure if we'll get one booked in for tomorrow?)

Lean on your account manager. Saying that I’ve not yet had to test out how responsive TTB are with OR on our account.

A month or two after our service went live in 2019, we were unfortunate to have a bad lightning strike. One of the many damaged things included the ONT (still working but speeds degraded), which I reported to then provider Cerberus late in the afternoon. Had a call around 9pm to confirm that OR would be there first thing in the morning. By 10am we had a new ONT and service back to normal. Couldn’t complain with that!

Pretty good test here!

Got a text at 4:30 am from TTB on the business phone that said the engineer would be coming in later this afternoon.

I get a phone call from one of the team saying an engineer has rocked up at about 7:30am! I head on down to the office to have a look, and have a nosey, and by the time i'd got there he had switched out the old ONT for a new one, played around with his iPad thing and volia we were back up and running.

Very efficient service from both TTB and Openreach this morning.

Great service there by both teams 👍

I'm amazed they have trained their staff to power cycle in this situation. A Red LOS (Loss of Service) is an instant case that needs to be raised with Openreach.

Not that it matters, not now anyhow, but I understood it to be the PON led (OLT registration or upper network issue) rather than LOS led (no or insufficient light). I agree that the latter is pretty much “red means dead”

In any event resolution by 7:30am the next morning with an equipment swap is very good. I’m sure the OP doesn’t begrudge them a power cycle which takes all of 15 seconds 😀
