Solved, thank you
============
Hello kids, my absence and silence from the forums since my BT FTTC issues (if you don't know of them already, I won't ruin your day by sharing the pain), has been due to eventually gaining some connection stability. Though were never fully resolved, it was a stress I could no longer keep in my life, so I learned to live with it.
However a new chapter is opening and I'll be moving to a place that will (depending on which home/area I land in) either offer Virgin Cable or FTTC.
My purpose here today is to share some of those FTTC capable locales and have any of you kind individuals help me understand some possible anomalies(?).
Firstly, I based this around the cabinet checker
https://www.homeandwork.openreach.co.uk/when-can-i-get-fibre.aspx and also BT's service checker
http://www.productsandservices.bt.com/products/speed-checker/For the following addresses, I found that there were multiple cabinets involved and the speed over distance was to my understanding, too good to be true.
49 Juniper road, Red Lodge, IP28 8TX connects to cabinet 11 which is roughly 3.59km away. Advertising 56-76mbps, minimum guaranteed 53mbps
32 Thistle Way, Red Lodge, IP28 8FR connects to cabinet 11 which is roughly 3.61km away. Advertising 53-74mbps, minimum guaranteed 49mbps
12 Gorse Close, Red Lodge, IP28 8LH connects to cabinet 3 which is roughly 3.06km away. Advertising 44-62mbps, minimum guaranteed 39mbps
5 Carnation way, Red Lodge, IP28 8TN connects to cabinet 6 which is roughly 2.90km away. Advertising 77-80mbps, minimum guaranteed 71mbps
1. The cabinet location for 11, 3 and 6 are the same, at (approximately) 47 Station Road, New Market, CB8 7QD.
- Are there multiple cabinets at that location? Or is this a misprint?
- If so, how many are there and where are the rest of them? i.e. 1,2, 4-6, 7-11
- Why are homes that are less than .20km away from another home in the same town, achieving only 2/3 of the speed as the other? 44-62 vs 77-80?
There's a lot of properties in Red Lodge, so I expected there to be at least 10 cabinets or more. What I cannot fathom is why they are all clustered together(I have never seen that before) at such long distances? The point of having multiple cabinets is to give the best (closest) coverage to various areas. Sticking in the same spot seems like a lazy way for OpenReach to service them, at the expense of performance to the customers.
From what I can see on the maps, those cabinet locations on Station Road, are closer to Kentford (and to some extent) Moulton to the south. It makes me curious if the cabinet map is accurate.
2. How can any copper connection (even if using VDSL2 or ADLS2+ LLU) achieve the numbers in the examples I gave above in a real world scenario?
- VDSL2 / ADSL2+ LLU can only go so far; 77mbps or higher at 2.90km seems highly unlikely and 56mbps or higher at 3.59km is even more wild
- How does a property in the same neighborhood area (39mbps) lose nearly 15mbps and yet is also half a kilometer closer to the cabinet? I presume it wouldn't, though note that this is the address (Gorse Close) showing a different cabinet number. If the cabinets are really separate and sitting side by side, then that means cabinet 3 has faults or some serious cross talk issues. Otherwise the closer, should technically be better (putting aside any terrible issues with the copper lines themselves, yet this performance result is true of all the addresses in that area).
I understand that no distance is often as the crow flies when it comes to cable run, therefore the above figures are even more impressive. Unfortunately I have no statistics such as noise margin and attenuation, though would imagine that a copper or mixed copper run of nearly 4km would bring you down to old school DSL/ADSL speeds of sub 10mbps.
Any insight is welcome.
