We're doing LLU purely for Ethernet access. We've obviously got the EAD-LA, but we're also doing GEA for FTTC/P and we're using Hatteras/Overture EFM DSLAMs (much like BTW) to do up to 8-pair, 40Mb/s EFM services.
Simon - our problem is that EBD only has a handful of exchanges in each area that you can go to/from. For example, we're looking to unbundle a bunch in Aberdeen, however EBD is only available from the Aberdeen Central OHP (Lochnagar Exchange) to Inverness and Dundee - neither of which we have plans for in the immediate future (well - we do, but that's another story). We're using a mix of Virgin, Openreach and SSE for backhaul around the place depending on suitability; EADs for example inner city between exchanges, Virgin for slightly longer stuff and SSE for the real long hauls. Unfortunately Aberdeen seems to only have SSE, BT and C&W fibre in the ground. We already have our main backhaul from Edinburgh to Aberdeen on an SSE wave, so we're now shopping for a second one for resiliency. C -- Charlie Boisseau Fluency Communications Ltd. e.

If you guys want we could grab a table at lunch in Brum and see what product fits best for what you are doing and what developments might be useful.

In a particular case, I've got 3 exchanges in Bristol. One is the OHP, and the other two are smaller sites, and are ASNs. They're all on the same chain. 1G EADs from ASN1 to OHP, and ASN2 to OHP are about 7.3k pa. 1G EBDs from ASN1 to OHP, and ASN2 to OHP are about 7.4k pa. My capacity requirements to the smaller exchanges are small enough that I could actually run ASN1 - ASN2, then ASN2 - OHP (as they appear in the EBD chain). In my simplistic head, this should be cheaper than running them both back to OHP individually, as I'm not using up two wavelengths on the ASN2-OHP path. However, I also accept that this isn't how EBD has been designed. In my case, it looks like EADs are the way forwards anyway. Smon On Fri Aug 16, 2013 at 06:42:38PM +0000, Neil J.

Although I might be misunderstanding what you need - perhaps you want to break out at each hop? In which case it's access so EAD is the product. It's probably theoretically possible to use the optical solution but process etc won't be setup for it. Out of interest are you folks going into exchanges for xDSL unbundling?

I've just been looking at this too, as $dayjob is starting to unbundle some exchanges. Although EBD is wavelength based, so you have a bit more flexibility what you can run over it, be careful with the pricing. In my case, I found that a bunch of 1G EADs between exchanges was cheaper than running 1G EBD's. And, one frustration with EBD - it's all based around chains between the ASN's (i.e. smaller exchanges) and OHP's (i.e. major exchanges). In my case, I've got two exchanges which are on the same chain back to an OHP where I also have a presence - but I don't seem to be able to take advantage of the "chain" - just buy a wave from each ASN back to the OHP. GEO do have fibre into quite a lot of the BT exchanges - they provide backhaul for one of the major LLU providers - and will sell you wavelengths (albeit on your own dedicated fibres). SSE are starting to dig fibre into a bunch more BT exchanges, and you might find that Aberdeen is on the list as it's their stomping ground. Alternatively, the likes of Enta or Expo-E have presence in a number of BT Exchanges (particularly in cities).
