Sorry, no idea who you think I am but it's not that hard to find me given I'm all over broabdand forums.
Fibre spine is BT-speak for the fibre network they use to feed cabinets, etc.
GEA is, as I said, access agnostic. However the customer connects to the Openreach network the interface is the same so from the operator's point of view whether a 10Gb point to point leased line, a consumer grade FTTP line or FTTC it doesn't matter they all come to the operator through the same cablelink product and layer 2 switch if Openreach choose to provide them.
I said that FTTP and FTTPoD were the same, neither uses a DSLAM, both are GEA products, I didn't say anything about the leased line products which are, naturally, point to point.
A cabinet isn't required for FTTPoD, they use fibre at an aggregation node on the path to the cabinet to build FTTPoD - see
http://www.btplc.com/Sharesandperfo...ts/Newsletter/Issue27/60secondguide/index.htm for build info and
http://www.openreach.co.uk/orpg/hom...sondemand/downloads/FTTPonDemandFactSheet.pdf for other details.
The cabinet just makes it economically viable to run the fibre out there to begin with. Without the cabinet being there there's no business case for performing the civils work to clear duct paths just to put fibre to an inspection cover on the off-chance someone takes it up. In an FTTC install the most expensive part tends to be getting fibre to the thing. The cabinets themselves are pretty cheap in the grand scheme.
The only difference between the FTTP product available to a small area right now and FTTPoD is the network build at the start. Once that's done both are handled exactly the same. It's just about getting consumers to pay up-front towards Openreach's network. Clever move actually.
Either way zero technology is shared between them. Per that BT Group 60-second briefing when FTTPoD is ordered they take a fibre from an aggregation node, plug it into a PON OLT in the exchange, and then build out the PON splitter closer to the customer. When BT blow fibre to cabinets they blow tons of it so that they can re-use it for FTTP at a later date. FTTPoD is someone paying Openreach a shedload of cash to get it earlier.
Hope that helps.
EDIT: Just FYI the part of that document you linked me to was headed 'choices'. There are no exchange-based DSL GEA products available, there is no point to point fibre product available over GEA right now. The GEA-FTTP price list is
here, the GEA-FTTC price list is
here, the 10Gb products are in the fibre-only ethernet section
here.
The document you linked is a consultation document from 2007, well before the portfolio of products had been finalised, hence the header 'NGA Technology Choices' and the presence, along with 10Gb PtP fibre, of exchange-based DSL.
