Has anyone checked if QoS is enabled on any BT Hub used?

With FTTP we are receiving 2.5Gbits/sec regardless of the package speed sold. Elsewhere they limit the speed of data sent to us to match the package bought and this also helps share that 2.5G out amongst the 30 or so properties on the same splitter, so it is an artificial limit under someones control somewhere.

I suspect they are tweaking these hard limits on different packages. It used to be FTTP was 330 down, but now it seems it is sold as 300, hence 314 has dropped around 30M. Guessing here but could they be trying to create a bit more leeway for higher speed packages, by limiting the maximum speeds on the existing ones.

The naming convention might be something to do with average speeds and not over selling it?

Naming conventions are just marketing to include the new Openreach tiers and make it easy for them to market it.

i.e. 100, 250, 500, 1000

That would be pointless as it would show 2.5/1.25Gbps for everyone with a working FTTP connection from Openreach. It either syncs and you get that speed or it does not and you get nothing. You might be able to read the loss in dB for the link (you can on a standard ethernet SFP/SFP+) but it is only of academic interest. Now if you had a line issue you might see some TX/RX errors but I would have thought Openreach would be monitoring that on the OLT anyway and would investigate if it became an issue.

On the otherhand they oversubscribe the service so it may just be you are now competing with other users on the same GPON link and are stuffed.

Could be but I can add that I was expecting something around 315+ download speeds(assumed 330 product) but only get around 290 as well, this is on a recently completed FTTP on Demand order and that is with only me connected currently. Paperwork from Cerberus states 300 as the download speed, I think it used to be 330. So I can't complain and not complaining, but it does suggest speeds have been reduced a touch.

I also don�t believe there is �DLM� on Openreach FTTP products. It is not required.

However, whilst I agree with that from the Openreach side of things, once it gets through the cable link at the exchange it is at the mercy of the BT Wholesale systems ....

For instance, the IP Profile on FTTC is set by BT Wholesale.

It shouldn't be doing anything, but maybe it is. It's a plausible suggestion, nothing more . Do BTW FTTP products have an IP Profile? Has anyone ever gone to Further Diagnostics on the speed test to find out?

Begs the question, are there any ISPs (yet) that take an Openreach FTTC (oops: FTTP) cable link and hence avoid the BTW systems?

Several small providers such as Sky,TalkTalk,Vodafone don't use the BT Wholesale links

Ha, of course. I also typed FTTC when I meant FTTP
