It could be down to many reasons, one being that BT Wholesale have upgraded some of their infra and network at the headend exchange but not completed it yet
The Backhaul Network is the Exchanges/Data Centres and Metranodes across the U.K.
There’s no one specific place, it could be the Data Centre in Derby or the Metranode in London for all I know? 🤷♂️
so what would you advise? wait while my neighbour that i share a fence with is connected to our own local exchange and receives 1gb fttp while i'm in a new build connected to an exchange 25 miles away and can only order 100mb after being told we could receive the full capability? All i'm really looking for is advise or someone to investigate if something can be done, it just seems really strange.
IMHO it’s going to be a records issue , not a physical issue, as already explained there are a very small number of ECI headends ( where location where the fibre service originates ) these can only deliver 330Mb , but if you were connected to one you would have an ECI ONT but you don’t you have a Nokia one , which means you are connected to a Nokia or a Huawei headend , both can provide 1Gb speeds ( sold as 900Mb )
Headends are not at every exchange , they cover relatively large area, ( many individual adjacent exchange areas are served from one headend ) and again as explained the distance the fibre travels before it reaches your location is fairly irrelevant , and the way the fibre cables are routed it would make no sense to have fibre cables from 2 headends in one location.
0800 587 4787 is the number for the BT FTTP customer service number , if you haven’t already you probably should contact them….you actually haven’t posted any speed test results etc , but presumably speed issues are why you have posted on here…..post the results from the BTw speed tester or a reputable alternative, use a device like a laptop that is capable of 1Gb speeds , using an Ethernet connection not WiFi.
