Plattville Google 320Platteville, Wis has the largest deployment in the U.S. Curtis Frankenfeld remembers the pain of early ADSL deployments but assures me those problems are not recurring. G.fast produced "No disappointments on performance. The results in the field on real cable approach the lab results." 

"The results using coax were flawless, with slightly better performance than twisted pair. The installers only had to do a small amount of repair, splitter removal and similar." Sckipio and Calix have been enthusiastic about the possibilities of G.fast over coax and now we have confirmation from a customer.

Curtis would like G.fast to support a larger vectoring group than the current 16 ports.

For now, they are only using it for smaller buildings to avoid the binder management challenges in bigger buildings. He doesn't expect higher port counts until Amendment 2/3 chips become available, possibly mid or late next year. He also would welcome a unit for buildings with fewer than 16 ports. 

They are using Calix's SDN and tying it into Century's system. Like the other U.S. telcos, they hope soon to implement  SDN widely. They've also looked at wireless alternatives to G.fast. Verizon is doing 5G highband and calling it "wireless fiber." So far, he sees both positive and negative 

I'm not going to move to Wisconsin but sure would like the 500 megabits, especially the fast upstream.

PLATTEVILLE, Wis.Sept. 12, 2016 /PRNewswire/ -- CenturyLink, Inc. (NYSE: CTL), a leading broadband services provider in the United States, today announced that it has installed G.fast technology in Platteville, Wis., resulting in the largest G.fast deployment inNorth America. Using existing copper and internal coaxial cable infrastructure, CenturyLink installed G.fast technology in 44 multi-dwelling units (MDUs) to provide internet speeds of up to 500 Mbps and higher to nearly 800 apartments in Platteville.

"CenturyLink's commercial G.fast deployment in Platteville, Wisconsin is the largest single G.fast implementation in the U.S. to date, highlighting the company's commitment to delivering ultra-broadband services – including Gigabit access – to its customer base," saidErik M. Keith, principal analyst of broadband networks and multiplay services at Current Analysis. "With the ongoing evolution towards unicast, OTT streaming video services, including 4KTV, demand for ultra-broadband connectivity continues to escalate. To this end, CenturyLink is leveraging extensive fiber network build-outs in conjunction with key endpoint technologies, with G.fast providing de facto FTTH services over existing copper access lines."

In 2015, CenturyLink deployed fiber-to-the-premises technology to the majority of residential and business customers in Platteville to upgrade the CenturyLink Televideo TV service to CenturyLink® Prism® TV service. That fiber network enhancement also enabled most residential and business customers in Platteville access to broadband speeds up to 1 gigabit per second. Many apartment complexes in this area that did not have access to those faster speeds are now able to connect to speeds up to 500 Mbps and higher, and to Prism TV service, through this G.fast deployment.

"We saw a great opportunity to use existing copper assets in our Platteville network to bring ultra-fast internet speeds to customers who live in areas that typically don't have access to these new broadband technologies delivering higher speeds," said Aamir Hussain, CenturyLink executive vice president and chief technology officer. "We take a fiber-first approach when deploying faster broadband speeds but enabling G.fast over copper infrastructure helps us reduce costs, speed time to market and effectively connect our customers to the power of the digital world in areas where fiber deployment is less feasible."   

CenturyLink is evaluating other locations, beyond MDUs, where G.fast technology can be used to give customers access to faster speeds, such as fiber-fed multi-tenant units (MTUs) and neighborhoods where fiber-to-the-curb (FTTC) allows for G.fast to push higher speeds over the short amount of copper into the home. CenturyLink is utilizing other new technologies on its existing network infrastructure to accommodate the growing broadband needs of its customers, including the delivery of internet speeds up to 100 Mbps to nearly 1 million homes and businesses using VDSL2 vectoring.

CenturyLink is utilizing the Calix AXOS G.fast solution for its G.fast deployment in Platteville, with all systems and services managed via the cloud through Calix's Compass Consumer Connect Plus software.

G.fast News
A remarkable 400 people attended the very strong Broadband Forum BASE events in Berlin and Las Vegas. Trevor confirmed BT would pass the million this year. Cioffi projected “Waveguide DSL” could carry 10 gigabits a kilometer as well as a terabit 100 meters. Werner sees a 4X improvement in upstream with cDTA. Much more in next issue.

Deutsche Wants a Gigabit, Finally Realizes 50 Meg Isn't Enough http://bit.ly/2zeZ5oZ
Deutsche Telekom is finally realizing that 50 megabit DSL won't make it against gigabit cable. VP Franz Seiser is blunt. "We must change radically, become disruptive and, above all, throw away things," he proclaims at BBWF. After years of DT insisting 50 megabits is plenty, we now hear "it is about Gigabit products" from DT's Robert Soukup.  
    A lucky building in Frankfurt will receive 500+ megabit service as ultra-conservative Deutsche Telekom experiments with G.fast. Soukup told BBWF, "We're going to have a field test in Frankfurt with G.fast and Fiber To The Building (FTTB.) We will know by the end of the year if this is the right way to go." Hint to Soukup: Yes it is. G.fast is working well at a dozen telcos I;ve talked to.
     The details are surprising. DT is going for CORD, Open Source, Calix, and Radisys. http://bit.ly/2zeZ5oZ

1.6 Gig in Sckipio-Calix Test http://bit.ly/Calix16
A telco tells me they are getting impressive early results from the Calix 48 port DSLAM with the new Sckipio 212 MHz chips. There still is work to do but this is encouraging. 
    Carriers want DSLAMs with more than 16 ports to reduce the deployment costs from the basement or larger field cabinets. Speed matters to the marketing side of the company; AT&T's CEO believes he must offer a true gigabit to match cable. (They've been getting ~750 megabits with first generation chips. http://bit.ly/Calix16

Reverse Power 4 Port DSLAM for Australia http://bit.ly/NetcommRP
Australia is connecting 1M homes to G.fast, some with a Netcomm distribution point mini-DSLAM. It's a small unit designed for pole or pit mounting. It's waterproof, pressure proof, and temperature resistant. Their matching home modem is bittorrent friendly, with two USB ports for a hard drive dedicated to sharing.
     A reverse power unit at the customer, the NDD-0100-01, can save the cost of bringing power to the DSLAM. They don't expect many orders until the second half of 2018, as nbn is waiting for the second generation chips. Netcomm demonstrated RP with BT Openreach in August. http://bit.ly/NetcommRP

Australia Makes it Official: G.fast to Million Plus http://bit.ly/GFAussie
No news here. In September, 2015, I reported Australia's nbn Going G.fast. This June. I reported the million home fiber to the curb (kerb?) was beginning. Unfortunately, they are no closer to figuring out where to find the needed $10B to $20B to cover the cost overruns. Instead, the parties are battling in Parliament about who is to blame. http://bit.ly/GFAussie

2 Bonded 212 Lines = 3 Gigabitshttp://bit.ly/twobonded
Sckipio at BBWF is demonstrating 3 gigabits down, nearly a gigabit up, over two phone lines, bonded. Twice the bandwidth (212 MHz instead of 106 MHz) times two lines is fast. Sckipio does great demos; at CES, they showed G.fast first generation chips delivering almost 1 gig upstream.
    “Sckipio is pushing Gfast to astonishing speeds with production silicon,” CEO David Baum proclaims. Calix is using the SCK23000 chipset in their 48 port gig+ DSLAM at the show. http://bit.ly/twobonded
