Small exchange to the wider world


[link to this post]
 
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:

Telewest (2004-2006): 256Kbps -> 512Kbps
University of Portsmouth's Horrible Network (2013 - 2014) - Supposedly 100/100Mbps
BT (2006 - Present): 8128/448 -> 22494/1211 -> 79987/20000Kbps (BT Infinity 2 on Huawei Cab)

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!

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.

SLU will have its own backhaul link from the cabinet , separate to BTW.

If you mean the same physical link then yes, probably. However it could also be that they (Call Flow Solutions) will route the fibre themselves to a bigger exchange which is quite common on smaller exchanges.

That's assuming they own the cabinets themselves and BT Openreach have nothing to do with it (Nothing planned for the exchange I can see on BT Openreaches website).

Even if they use the same link, you wouldn't have to worry because they'll likely have an equivalent of a point-to-point leased line from BTw for backhaul purposes - Other BTw traffic from ADSL kit wouldn't affect it as it would be guaranteed bandwidth - This is if they have their own cabinets.

Call flow are a sub look unbundler -- there is no choice in terms ot CP's and you can only by a solution from Call flow -- its is not FTTC (from Openreach) -- look slike KCC took it out of intervention area --

Aha then the backhaul they use (Likely through BTw as there are no other LLU providers at that exchange - if they use it) will be guaranteed to Call Flow (Much like a leased line).

Could be 1Gbps depending on how many cabinets the exchange serves and whether Call Flow use it as a primary exchange (Where all cabinets in the wider area connect to).
You'll need to ask Call Flow about this.

You may also find your exchange isn't where your cabinet is connected to - It could be connected to a larger exchange in the area where all other cabinets connect to.

Even still it may be a dynamic backhaul - They may upgrade it every once in a while as more users & cabinets are added.

You'll find all of Call Flow's cabinets on an exchange are linked (Usually via 1Gbps interfaces) together inside the exchange with a high-end switch which is where they are all connected to the backhaul. So it's very tricky if not possible to determine the backhaul size.

Anyway, it's probably 1Gbps or multiple thereof as their backbone network will more than likely be Ethernet.

Ask Call Flow Solutions - They may tell you.

No need at all for sub LLU backhaul to go via a telephone exchange at all.

Boils down to CallFlow needing to provide details.

Sub Loop Unbundling (SLU) has been around for a while, but it’s safe to say
that some communications providers have struggled to make it work for them.

That’s definitely not the case with Call Flow Solutions, a Kent based CP, which has
grasped the opportunity offered by SLU after completing a hugely successful pilot.
The company is now in the middle of two more SLU rollouts, with even more on the
horizon.

So what’s the secret of Call Flow’s success?

Sub Loop Unbundling

Sub Loop Unbundling (SLU) provides you with access to a partial local loop. It connects the network termination point at your customer’s premises to a concentration point or a specified intermediate access point in the local network. We’re responsible for the provision, maintenance and repair of the SLU circuit, which comes with Shared Metallic Path facility (SLU SMPF) and Metallic Path facility (SLU MPF) options.

Key benefits:

Offer high speed digital services by placing the necessary equipment near the Primary Cross Connection point (PCP)
Provide both MPF and SMPF services to your customers
Avoid the need to install equipment in BT exchanges

Looks from his deletion and repost of the first strange one that he replied to you by mistake?

The later one to me I think I understand why he posted that smile.

He's got his "End quotes" messed up which doesn't help.
