ECI cabinets will support upstream G.INP.

However (even if they did not), that is still not a commercial decision to spend several hundred million replacing all ECI kit.

If they actually start to function like Huawei cabs, offering the same facilities then there is obviously no need to replace them. But when will they?

Their job is to perform a VDSL2 service and they do exactly that.

No one has ever promised you or sold you a service that two different hardware manufacturers will perform identically with the same features.

That expectation is obviously not unrealistic.Why should the features vary by postcode?

which magic mirror did you get that fictional cost from?

Brought at very high bulk e.g. hauwei ma5616 is priced at about 600usd per unit (1000+). ECI units are cheaper.

How many ECI cabinets exist in the UK?

With the figures you have come up with you have claimed the dslams cost more than the fibre itself.

Does the Huawei kit magically make its way into the ECI cabinets?

Around one third of cabinets are ECI and I don't think my numbers would be far off when you consider the equipment, logistics and deployment costs.

When the G.fast node is in operation would it not matter if it was an ECI or Huawei cab as they would be just acting as a pass-through to the node?

Yes that's the one, thanks for the detailed reply although I was aware why it was removed, it actually worked very well on my line which normally has interleaving applied.

It will be interesting to see how my line improves with G.INP and the new lower SNR margins, as it is under performs for the distance from the cab so any improvements will be welcomed.

Here is a question.

What is the business case for replacing these dslams in the early rollout areas? after all g.fast still works right. They are also capable of pumping out 330mbit to 10% of lines connected so there is no marketing justification.

You cannot apply one set of rules to one situation and not to another.

if it would cost BT the best part of a billion pounds to replace ECI dslams they they have some serious inefficiencies in how they work.

Just out of interest did you cost in the controller cards and line cards or are you just talking an empty backplane?
