Accuracy of checker


[link to this post]
 
The BT checker says that my estimated speed is 60mb, even though the cabinet is right outside my bedroom window..

so, is there a chance here that i'm connected to a different cabinet. (would be mad)

or, is the checker just. meh?

But what route does your line take?

It could leave the cabinet in a duct to a pole 100-200 metres away and then return to you from pole to pole to pole to house. There are a couple of houses here like that; directly opposite the cabinet but have 300m long lines.

Moradin you can find your cabinet number here, then just have a walk around until you find it.

I know where my cabinet is - it would be more useful if you replied to the OP.

I know you do, but I gave the link for Moradin to confirm which cabinet he is connected to.

Lots of people just hit any reply button they can find - especially on the bottom post when displayed "flat".

There are plenty of boards that only have flat threads, and a single reply link. People used to that style almost-inevitably hit reply at the bottom.

Why, because of the unusual way these forums work, and you can't expect everybody to know they are not like the majority of other forums.

Edit: Is it possible to get an email when anybody replies to a thread, rather than one of your specific posts?

I have the same 63M down 20M up on the BT wholesale checker, but when I had FTTC installed th engineer used his test kit and that was syncing at 96M/53M. So it looks like the speed quoted is an estimate from previous average data. I bought a 40M/10M service and this syncs at 39992K/9996K.

That's the theoretical maximum sync, not the actual sync. As in
Max: Upstream rate = 14727 Kbps, Downstream rate = 58396 Kbps
Path: 0, Upstream rate = 14641 Kbps, Downstream rate = 57485 Kbps
on a longer line.

Ermm... no, not quite.

Clicking the "Favourite" button will add the thread to the "Favourite Threads" box in My Home, and any new (ie unread) posts in that thread will cause a "New" icon to be displayed next to it.

But it won't send an email, you need to visit tbb to check.

I know that the cabinet outside my window is cab 7.

I know that the pole opposite it SHOULD be connected to that cab.

but, if thats the case, why does the BT checker say 60mb, when it should say 76mb.

I'm speculating that the pole, may be connected to a further distant cab. (which really wouldn't make sense, because the pole is 25 feet from the cab.. but hey, this IS bt we are talking about)

I'm hoping someone else on here, is right next to their cab, and has had the same result from the speed checker.

In reply to a post by iand:
So it looks like the speed quoted is an estimate from previous average data.

One of the biggest limiting factors to VDSL2 speeds is the crosstalk from other subscribers.

BT's estimates have, in practice, been pessimistic compared with the experience of people signing up - who, by the nature of the rollout, are the first takers where there are no other subscribers to cause crosstalk interference.

To me, it suggests that BT's estimates take into account a certain level of future crosstalk, from future subscribers. And that all people in the first batches onto a cabinet will have higher speeds than this... but only until more people join in.

An estimate of 60Mbps suggests that BT think you are 300-400 metres from the cabinet.

Either their database is wrong, or you actually *do* live that far, and aren't connected to the cabinet you think.

I too am not connected to my closest cabinet (if I were, I'd have had fibre about 6 months earlier). We're on an estate built in 1995, and that closest cabinet is also on one of the roads of the estate. However, our line is fed from a cabinet off the estate that certainly pre-dates our construction date.

Possible reasons?

Although you are currently next to the cabinet, perhaps it didn't exist when your house was originally built - and your line goes back via a different cabinet. Perhaps that original cabinet filled up, and the new one was added subsequently.

It was a max 96M/53M as reported on the hand held tester. As always the line was limited to 40/10 as that was all I paid for.
