Hi,
I live in a largish town and 90% of the urban exchanges have an LLU service of some sort, CPW did a mass roll out a few years ago.
Unfortunately mine has been left alone and is a Market 1.
4,400 lines and no LLU at all.
Recently very small exchanges like Bayston Hill have had Sky unbundle them. Broseley has Orange and CPW yet we have nowt!
Is there anyway I can find out why? The exchange is WNHLN.

try to find out proximity to POP's used by these isp's. How far away from the nearest city?

move to Wem
There is no hard or fast rule why they do or dont, some would see a exchange viable some dont. Each LLU provider has there own set of rules etc but soon enough i recon most will be done by TT or SKY.

Wolverhampton is a major hop for most ISP's 15 miles away.
Wellington, Oakengates and Stirchley all have Sky. Wellington the biggest exchange around here, 6 miles away has C&W, CPW, Sky, Tiscali and Orange.
I'm not sure if it's got something to do with the actual size of the exchange. It is on the small side, but it's probably bigger than Broseley!

It's pretty obvious that ISPs aren't going to unbundle cabinet equipment so all they need is to arrange exchange backhaul and use GEA. If WBC can be made to work then they don't even have to worry about backhaul from the exchanges. WBMC might even be good enough to allow them to differentiate service and pricing.
I suggested a couple of years ago that LLU could be facing a form of extinction. So far 21CN hasn't really lived up to the hype but right now if I was an LLUO I'd be suspending further roll-outs.

This isn't the first time I have heard of something like this.
TalkTalk (CPW) have unbundled a 385 line exchange, about 3 miles away from me and have not bothered with the 1336 line exchange I am on. Not sure if it matters but my exchange was first enabled for ADSL in 2003, while the 385 line exchange was first enabled for ADSL in 2004.
Something odd is going on here...

Could be many reasons for it...
Space at the exchange for their equipment
Cost to get a tail to the exchange from another of their access points (there could even be things preventing this such as construction work required, road closures etc).
The respective LLU provider currently has no/few customers on the exchange so converting/enabling would take longer for a ROI compared to other (even smaller) exchanges that may give faster ROI.

That's the exchange, building with the blue roof with the woodland to the north of it.
It's small but i'm pretty sure they could get LLU kit in there.
Would it matter that there is little to no resedential premises around it and that the lines are quite long?
TalkTalk unbundled all exchanges with 6,000 resedential lines + it seems.
I would only leave Xilo for Sky due to price. If CPW came available then I would still use Xilo, just resold Opal. The only reason I want LLU is to get away from BT's horrible DLM and profiling.

Not just those..

That has had Talk Talk and Sky appear in the last 3-4 months and it is a small coastal town... not near any major cities.

Sorry Matt, I meant using the Telford & Wrekin, CPW exchange list on Samknows.
Yep, I've noticed Sky especially are unbundling exchanges with as little as 2,000 resedential lines.
They have recently done Bayston Hill & Harlescott in Shrewsbury which on lines are smaller than Hollinswood.
Bayston Hill actually looks smaller on physical size too.
I don't get it.
