Small exchange to the wider world

Is there a typical size for the link between a small, rural exchange out to the wider world? 155 Mbit? 1Gbit? 10Gbit? More, less or something in between or is there no hard and fast rule? The exchange I'm thinking about is Goudhurst (NDGOU) so if anybody knows about that exchange in particular even better!

Physical link could be 10 Gbps or 100 Mbps, what is important is how much capacity is given to the tunnel your connection uses over this link.

Depends - you can rarely tell because the exchange could be used to house backhauls from other smaller exchanges in the area.

Your DSLAM will likely have a 155Mbit link to the backhaul because it's still a plain old ADSL Max DSLAM.

Bearing in mind there's no LLU at your exchange and seeing as there are around 1100 lines in total, I'd imagine it has a 155Mbps backhaul which may or may not all be in use.

If it was 21CN enabled (Which it isn't at the moment), I'd have said 1Gbps.

Re: your first question - Very small exchanges which haven't been upgraded to 21CN will mostly have ~30Mbps backhauls to the closest bigger exchange in a town for example like is highlighted on the Kitz website:

Back in the day Tiscali when selling 1 Mbps connections, used to only provision 2 Mbps for 100 customers - hence why at peak times things slowed down.

Thanks for the replies. I'm trying to explain to the SO's teenage son when he throws a hissy fit about Xbox live being slow that Plusnet is actually a decent provider and that there is more to take in to account than just the choice of ISP.

Faster services are now being offered at the exchange by Call Flow Solutions as part of the BDUK project

Am I right in assuming that the SLU will still use the same link from the exchange out to the internet as the BT Wholesale ADSL products?

No not right. Likely callflow have some other backhaul option

We've probably seen your router stats in the past, but any chance of you posting what they are now please?

Also, is the Xbox problem a new game, that Plusnet may not be recognising as such?

This is at the SO's place not mine so I don't have access to them right now but off the top of my head the stats are fine. He's more often than not playing FIFA 14 so I'm sure Plusnet know all about that one!

He's almost certainly running wirelessly. Have you looked how that is performing?

No, he's got an ethernet cable running off a homeplug. Pings and speedtests are the same as when connected by ethernet to the router.
