I believe they are the first in the world to promise bonding to customers. Calix is now shipping AXOS G.fast nodes ready to bond two 500-800 megabit G.fast lines for true speeds over a megabit. Local company Allo in Lincoln has begun building a $100M fiber network, inspiring Windstream to become the first North American to order G.fast. They didn't give a deployment date, but probably want to go as fast as possible. As you can see from the map, Allo is already building. Demand is off the charts. Calix is shipping AXOS for revenue, not just trials.
While a gigabit is theoretically possible from a single line of G.fast, real world performance is more likely 500-800 megabits. Improving G.fast for a real gigabit and longer reach is likely in the next year or two, but some companies can't wait. Three North American cablecos are offering customers a gigabit today; most others will go to a gigabit with DOCSIS 3.1 next year. Also, do not forget to visit the gambling sites online casino ideal

BT has found success in the lab by upping the power, adding more bits/carrier, and modifying the Power Spectral Density. The standard is being revised and the chipmakers are working furiously. Blue and green lines in the chart project the results from a model by Daniel Hincapie and Mathias Leibiger of Fraunhofer, presented in an EE Times article. A map is not the territory and simulations are not working chips, of course.
Their simulation projects an improvement of 150-200 megabits at loops under 100 meters, typical in apartment buildings. Lucky tenants will get a gigabit, a crucial goal for AT&T. They will be selling G.fast as part of their Gigapower offering, so they needed the gig for marketing purposes.
At 300-350 meters, BT's target distance, the newer units may raise speeds 20-40 megabits. Above 400 meters, there is little difference expected.

Kick Deutsche Telekom out of the buildings and everyone gets 100 megabits more. Sharing copper lines became obsolete when vectored noise reduction became practical, first in VDSL and now in G.fast. As processors became fast enough to cancel noise across the lines in the binder, speeds double if one operator is in control. Deutsche Telekom is demanding a monopoly where they upgrade to 30-100 megabit vectored VDSL; City-owned Netcologne is instead offering 500 megabit+ G.fast.
Technical officer Horst Schmitz tells Golem.de they will connect 250,000 homes in 2017 and another 100,000 after that.

World leader British Telecom is praying they'll get 200-300 meg at 400 meters. Update 7/28 Windstream is the first using bonding, which means the numbers are not so crazy. Still unlikely, however. *** Thomas told investors he will get double the reach. Sean Buckley of Fierce reports Windstream will deploy G.fast. Update 8/6 Removed 2017 date. Might be 2016.*** They have a million DSL customers, down 40,000 on the year, scattered in the U.S. South and Midwest. Only 26% of those customers can get 50 megabits, while cable across most of America is at 200 megabits headed to a gigabit. As you can see in the press release below, Windstream, like Frontier, is selling 20-~60 megabit service as "up to 100 megabits."
CEO Tony Thomas is a finance guy who needs to spend more time listening to his engineers. Buckley quotes, "G.fast amendment 2 has a lot of potential and we're working with our vendors to make sure that can go into the products as we look towards 2017," Thomas said. "You'll be able to get 200-300 Mbps speeds at further distances of 2,000 to 3,500 feet from the home." Both theoretical studies and the early chip designs don't expect those speeds to go nearly that far.

Ethernity going for 48 port DSLAMs. You need a heckuva lot of processing power when you are pushing 10-20 gigabits through a DSLAM. The company has been supplying network/flow processors for Ethernet controllers and similar for more than a decade.
Xilink's Zynq combines dual ARM cores for control with programmable gate arrays for the dedicated application. FPGA's can be extremely powerful today. A different "Xilinx 16nm FPGA packs 5.2 billion transistors to support seven programmable cores." Rick Merritt.

These are my estimates, not from BT. I combined Andrew Ferguson's mapping results with cost estimates from several industry sources. Carriers use DSL instead of fiber because it's much cheaper, with likely costs of $100-$300 for the gear and installation. Even so, I was amazed when I calculated the BT cost for 10M homes servable. It's probably less than ~$300M/year for four years.
That's a heckuva of money to you and me, but a very small investment for a company the size of British Telecom. ~$300M is ~1% of revenue and 10% of the capital budget. It's probably less than BT is currently spending on DSL at slower speeds and will not require increased investment. The cost will be less if you make some plausible assumptions.
