FTTPoD availability/coverage


[link to this post]
 
Does anyone know whether the cabinet for your address will have to be FTTC enabled to be able to order FTTPoD? I look after a couple of sites where the current lines are fed from non-enabled cabs but I know that other cabs very close by have fttc twins. In one case , if I read it correctly, the plant map I saw suggested that there is ducting directly between our cab and one I know to be enabled less than 150m away.

It is my understanding that the cab the line is fed from would have to be FTTC enabled to allow an FTToD.

The most likely state of affairs will be that BT will allow you to order FTTPoD if their database thinks you can - and it will be nigh-on impossible if the database says otherwise.

The data in the database will dictate things *so* much more than, say, the presence of linking ducting in the ground.

So it depends on how BT populate their database in the first place.

If they go with the current FTTC status of the cabinet (as they have said so far), then you are probably out of luck.

If they go for a system that checks for the distance/accessibility of the nearest aggregation node to the cabinet (which is what your new fibre will actually connect to), they might be a little more flexible.

This way makes sense to me, surely BT have the sense (perhaps not) to quote for all customers, regardless of whether their cabinet is enabled or not, surely it is the presence of an aggregation node that should determine availability.

I guess we'll find out soon enough when it launches.

Yep had that confirmed from two different guys in the hierarchy at Openreach. Even if the aggregation node is outside they won't run FTTPoD from it if you aren't connected to an enabled cabinet.

I guess they don't want to break network segmentation.

I can certainly see why they'd want the new fibre network to be segmented effectively, but that doesn't mean that it has to be a direct 1:1 overlay of the copper segmentation.

Certainly there is no need for the new fibre installation to *have* to go via the cabinet, and there is no need for the network topology to have to look identical.

For example: I don't know what the deployment plan looks like for the chain of aggregation nodes as they snake out from an exchange - but one document I saw from BT suggested that they should add the extra fibre, to change the topology from a tree/branch structure rooted at a single exchange into double-ended chains that ran from exchange to exchange, giving backup routing to the core network.

Either way, there is certainly no need to assume that there is a 1:1 correlation of aggregation node to PCP.

However, I am perfectly prepared to believe that the restriction is in place for ease of administration frown

They've already broken the segmentation by feeding many FTTC cabinets from a different exchange from the PCP. Maybe even in the case of the two users currently asking this question.

As far as I'm aware the fibre cabinets go back to their 'home' exchange, the same one as the PCP, then from there go on existing fibre routes to the handover exchange?

I would welcome correction but that was my understanding.

On thinking about it, that seems highly likely. Dammit! smile

Well I am 100% sure that the fibre feeding DSLAM cabs in Eversley goes straight back to Crowthorne.
