Thanks for the reply.
Sorry that was a typo should have read secondary to the copper wire.
I'm still not sure I understand. Anyway...
According to the openreach engineer the cabinet is at end of the road.the address checker said cabinet 25 in Didsbury so need to check that out exactly where that is. The number checker didnt return anything.
I should have realised - you mentioned Talktalk, so the number won't give a result on that particular checker. What estimates did the address checker give you?
Cab 25 can be found here, on Elm Rd:
https://www.google.co.uk/maps/@53.420414,-2.239032,3a,75y,338.91h,56.43t/data=!3m4!1e1!3m2!1scgpneEGIyNrGRGlAkB8Cig!2e0The FTTC cabinet looks to be around the corner, on the main road. The distance between the 2 cabinets will add 30m onto your line length.
Some Bt customers on my road get 60+ others get 30 for some inexplicable reason.
It ultimately depends on the length, thickness and materials used. The route the cable takes matters - for some, it loops down the road on one side, and back on the other. The quality of the joints also matter.
You shouldn't necessarily expect that everyone is even on the same cabinet. Where I lived last, some houses were wired overhead out the back (ourselves included) and got 80mbps to the cab in that direction. Some others were wired underground out the front, to a different cabinet, and were estimated at 40-50Mbps. The drop-off to further down the street was quite extreme too - I suspect that there was either thinner wire involved, or aluminium, in the latter part of the street.
On average, a speed of 60Mbps is likely to mean a line length of around 500-600m. A speed of 35Mbps is likely to mean a line length of around 1000m. But those are indeed averages.
If it is so close do i have any rights as to minimum line quality.
The USC means you have the right to a voice connection, and a minimum of (IIRC) 28Kbps on dial-up. There are indeed minimum quality requirements for these, but nothing as yet for broadband connections.
Usual story. Verbally was told 50 plus.day before install email estimate saying 32 to 45.
Dont understand as some people on my road get 60. Bit sneaky.
One of the things that affects FTTC broadband is known as crosstalk - which is interference caused by other FTTC subscribers. This extra noise causes speed to reduce, and errors to increase - and things only get worse as take-up increases. And we are not talking of small impacts here, either: up to 50% of the theoretical speeds can be lost in the worst case.
Your cab has been in place since 2010, so has had plenty of time to get high take-up.
There's a double-whammy with this noise too. If the error rate increases above a certain threshold, old-style DLM would intervene to introduce error protection. This would increase latency, and reduce speed even further. Thankfully, this style of intervention is being phased out, as we speak.
Unfortunately, without a lot of line statistics from you, we can't really say anything about what state your line is in; we can just let you know about the things that might be affecting it.
