adtran 212Demos double frequency G.fast and cDTA with Deutsche Telekom. Adtran only claims "gigabit rates" but the technology is designed for over a gigabit and a half, combined upstream and downstream.  I infer from their comments they are ready to ship. They also claim good performance from DTA, rapidly shifting upstream and downstream ratios based on traffic demands.

Sckipio's supplying the chips for cDTA, according to Richard Chirgwin in The Register. With the DTA now working on ordinary twisted pair. Telcos to claim "effective speeds of 500 upstream, 500 downstream." G.fast from fiber to the basement or wireless to the rooftop now outshines gigabit DOCSIS, especially on the upstream. Few cablecos are likely to improve their upstream significantly before Full Duplex is ready next decade. Verizon is heavily advertising their 50/50 & 100/100 Fios speeds because the higher upstream is winning customers. 

Rami Verbin of Sckipio is one of the most creative chip designers I know. He's been working on continuously varying the upstream/downstream splits in G.fast. His models were very convincing and the chips have been highly anticipated.  

In a joint press release with DT, Adtran says, "ADTRAN demonstrated the new 212MHz G.fast standard, which doubles the usable spectrum. This doubling of the usable spectrum allows service providers to deliver gigabit rates over a single copper pair, enabling robust fibre-like service delivery all the way to the customer premise. In contrast to cable systems, the bandwidth of G.fast is dedicated and available for each customer. The tests, leveraging the first commercially available 212MHz DPU also demonstrated the second phase of DTA. cDTA, like the earlier iDTA feature, improves G.fast upstream performance by four to five times by dynamically balancing upstream and downstream capacity to match residential traffic patterns in real-time. cDTA also expands the applicability of this feature to existing phone wiring, thus covering nearly all residential and commercial premises." 

I've sent a note to Broadcom and Metanoia asking about their progress on 212 GHz. and cDTA, which I'll add to this article if they also have news. 

AT&T is expanding G.fast out of district, although the serious volume is a few quarters away. Century, Frontier and the smaller telcos are natural targets for T and they want to have a counter if VZ comes after them in fixed. "They will get better at it, they will get faster at it, and will be ramping." Modest volume likely until 2018.

Australia's NBN has now confirmed they are going with Adtran for a million lines of fiber to the curb. Officially, that isn't G.fast but it makes no sense to make any other choice. Also likely modest volume until 2018.

Finally, Deutsche Telekom's new management is realizing VDSL may not be enough to compete with cable and fiber. Then CTO Bruno Jacobfeuerborn in 2015 said they would go for G.fast, but the finance side veto'ed the budget. Looks like they are back in the game. G.fast is the right choice for the >5M large buildings in Germany.

Adtran had a superb quarter and these new deployments suggest business will be good at yearend. Wall Street thinks so and the stock jumped 15%. Stanton believes their SDN variant Mosaic is a powerful differentiator and reports most new customers are using it. The new contracts seem to have a large services component, which pulls down margins in the short run. 

Calix and Adtran intend to prove the report of the death of the U.S. telecom industry is premature..

For the record: Adtran will be paying my expenses to their event in Huntsville in August. I'm going to try to bring Jennie and her camera..

 

ADTRAN and Deutsche Telekom Look to Ultra Broadband Evolution to Advance the Gigabit Society

Lab trials proving latest G.fast innovations, 212Mhz and cDTA, will accelerate deployment of ultra-fast and gigabit broadband services

DARMSTADT, Germany--(BUSINESS WIRE)--Jul. 18, 2017-- ADTRAN®, Inc., (NASDAQ: ADTN), a leading provider of next-generation open networking solutions, today announced the start of lab testing of the latest innovations in the G.fast standard, 212MHz and coordinated dynamic time allocation (cDTA) together with Deutsche Telekom (DT). DT is evaluating these ultra-broadband technologies using Fibre-to-the-Building (FTTB) deployment models allowing the use of existing cable infrastructure within the home. This will allow the rapid deployment of ultra-fast and gigabit broadband services with minimal disruption. The low cost per subscriber connection pays directly into achieving European Commission’s Gigabit Society goals.

ADTRAN demonstrated the new 212MHz G.fast standard, which doubles the usable spectrum. This doubling of the usable spectrum allows service providers to deliver gigabit rates over a single copper pair, enabling robust fibre-like service delivery all the way to the customer premise. In contrast to cable systems, the bandwidth of G.fast is dedicated and available for each customer. The tests, leveraging the first commercially available 212MHz DPU also demonstrated the second phase of DTA. cDTA, like the earlier iDTA feature, improves G.fast upstream performance by four to five times by dynamically balancing upstream and downstream capacity to match residential traffic patterns in real-time. cDTA also expands the applicability of this feature to existing phone wiring, thus covering nearly all residential and commercial premises.

“Operators in highly competitive, dense urban or urban environments are challenged to extend gigabit services due to the time and cost that can be associated with pure play FTTH techniques,” said Jay Wilson, senior vice president at ADTRAN. “With G.fast innovation, operators, such as DT, can significantly accelerate Gigabit Society goals by launching gigabit services over their existing infrastructure dramatically reducing subscriber disruption.”

These two most recent G.fast advancements, 212MHz and cDTA, extract even greater overall performance from an operator’s existing assets, and in many scenarios, eliminates the need for full FTTH for years. For the first time, these G.fast innovations enable service providers to more rapidly and cost-effectively extend symmetric gigabit services and expand ultra-fast broadband to the wider market.

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
