Multivendor FTTP Confusion

You know it's serious when I find myself asking about things on here.

I'm working on a project, as one does. I'm having an excruciating time trying to get a straight answer out of which variety of OLT serves a couple of postcodes.

WF2 8ZA and 8ZB.

I suspect they have mixed technology PONs with some ECI and some Huawei. Openreach assure that it's all Huawei - they are wrong - BT Wholesale if there's Huawei kit there have no 10G Cablelinks to any of it.

A property on the postcodes most definitely had an ECI ONT. These don't cross technology. However a more newly built one has Huawei ONT so either there are multiple PONs with different technologies or they've taken the hit on telemetry and provisioned Huawei ONTs onto ECI OLTs as a temporary measure.

There are maps showing cabinet mappings to OLTs. Must be something regarding PONs to OLTs somewhere?

Small response to myself - probably irrelevant but all commercial FTTC cabinets on this exchange, Wakefield, are ECI. Subsequent BDUK cabinets are Huawei. There are a pair of ECI OLTs and a pair of Huawei OLTs at the headend there.

There is no G.fast.

The bottom of Broadway, my daughter lives there.

Openreach are accurate in what they have told you!

I wouldn't hold your breath on Wholesale upgrading to 10G CL for this one either, likely in for a wait.

Interesting. There are a bunch of ECI ONTs all over the place in the properties. When did they start mixing them?

I guess following on from this why the reluctance to purchase the 10G Cablelink? Lack of FTTP/G.fast to serve? Anathema as it is to Mike 3.5% Kiely BDUK are doing some FTTP in the area.

Actually never mind on that one. I wouldn't be that surprised if they've done what they did when FTTC was kicking off again. Relied on LAGing rather than upgrading chassis to provide more 10 GbE ports and they're now out of ports in the cards and slots in the chassis to install cards with 10 Gb ports.

Hang on. If Openreach are right as blmcg says, then they can’t be mixing them.

Therefore either Openreach are wrong, or somebody there misunderstood the question.

ECI ONTs may be used with Huawei OLTs. It's not ideal for a bunch of reasons but it's doable.

Oops, sorry . I got mixed up about the topology you had described.
