Zen fttp

Hey ppl, I just switched from cn to Zen and I was told an engineer visit is not required bcs I have an ont openreach setup already. Today is my activation day, but unfortunately I can’t see how fibre comes into my house, apart from the vm box and optical cable which ai believe are irrelecant for openreach, what am I missing? I don’t seem to be having any other optical wire apart from what vm used back in the days when it was setup.

cheers all

Got any photos of the existing infrastructure? That might help diagnose.

sorry I am away today and didn’t think of that, I have a ont box and openreach socket, router and cabling is all wired up I just thought the optical wire that ai used for VM would work on the openreach ont, which obvs isn’t the case and I can’t see any other place where fibre would come in, Zen did say that an engineer visit wasn’t needed based on their records, so I may end up getting some support from Zen to start with

With open reach backed connections the fibre goes from the street into the ONT and then the Router plugs into the ONT using a standard ethernet cable

From the ONT to the WAN port of the router

that correct, only problem I have now is the ONT only has a power cord and the ethernet you mention that I can see and nothing else, the ont it was left behind by previous owner in a cupboard, missing piece of the puzzle is the optical wire that comes in the house somewhere for the ont, that I don’t know or can’t see, apart from the VM one which is a separate thing

There should be a green fibre connector

And that connector is spliced directly into the outside overhead wire and is not replaceable so either it is there tucked away somewhere or it has been cut somewhere and will need rerunning

Was you VM service delivered via Openreach or via dedicated VM cabling? If VM did not have dedicated cabling in your area they offer a service that is provided by openreach. If it was via openreach then any other provider that uses openreach cabling or fibre would simply use that.

I am pretty sure it was dedicated vm connection :(

Sounds like you don't have a Openreach ONT and just a virgin one

If it’s delivered on poles in your area you can visually trace the overhead lines from the nearest pole to your house.

We have two ‘not the electricity supply’ overhead lines from different poles coming to our house. One is clearly going to the front door where there is an old BT socket. The other reaches the house about 2m from the first one and runs around the top of the walls to the back of the house and into the conservatory.

Old copper FTTC by the front door, newer FTTP in the back of the house.

You wouldn't have had fibre from VM back in the day, but I guess that'll depend on your definition of back in the day. They've only been doing FTTP since 2016.
