Light Green: Incumbent likely:  France, Germany, Italy Leader -- Sckipio Technologies -- Modems can do what ADSL & it's successor VDSL can't: Deliver fast upstream or down, whichever is needed most. Comvergence sells to Australian businesses 300 up, 300 down and finds that is preferred over any flavor of ADSL or VDSL. I wish I had the choice: Jennie does video and we need the upstream. (Did you ever think about how large 4K video masters are?) The people in the next office might have an opposite need.

Comvergence runs fiber to the basement where they have a DSLAM and phone wire from there. Experience is that will support 500-800 megabits, split between upstream and downstream. Most systems are set mostly downstream, but Sckipio demonstrated 750 megabits upstream last year. (below)

The prize in Australia is the big National Broadband Network contract. They are installing 700,000+ lines of "fiber to the distribution point" as well as millions of lines of vectored VDSL and fiber home.

NBN can't buy from Huawei or ZTE for security reasons, reducing the competition for the contract. Alcatel had it all initially but now Adtran also has a share. Calix works with Ericsson, who supplies wireless to NBN. I'm sure they are in there pitching. 

Here in New York, Verizon can't bring me more than 6 megabits and I had to deliver DSL Prime over cable.

World’s first solution to support DTA over multiple vectored lines concurrently

Ramat Gan, Israel – October 11, 2016 – Sckipio Technologies and Calix, Inc. announced a joint implementation of the world’s first collective dynamic time assignment (DTA) technology running on a 16-port vectored distribution point unit (DPU). This will allow broadband subscribers to gain access to the highest possible upstream and downstream capabilities that has to offer.

Earlier in the year, Sckipio announced the invention of DTA (also known as dynamic bandwidth allocation). At that time, DTA was only available on low crosstalk environments such as coax applications or single line scenarios. Now, close coordination between both Calix and Sckipio have resulted in the ability to push further by adding support for the higher density, higher-crosstalk environments that arise when twisted pair bundles are present.

The system is designed to listen for the demands of each consumer and to coordinate the upstream and downstream traffic to optimize the solution for the subscriber based on how he or she really uses broadband. As a highly sophisticated system, it analyzes traffic across all the ports and optimizes the performance for the entire system to ensure the highest overall performance at all times – resulting in the highest customer satisfaction.

“Broadband success is all about technologies that enable anyone to provide modern bandwidths to everyone,” said Greg Whelan, Principal Analyst, Greywale Insights. “Cities and buildings face the same barrier to success– the embedded base of wires. The advances in eliminates this and should fuel broadband success around the globe.”

Comvergence Leverages Calix AXOS Solutions to Rapidly Bring Gigabit Speed Potential to Australia MTUs

SYDNEY, Australia, April 26, 2017 (GLOBE NEWSWIRE) -- Calix, Inc. (CALX), the world leader in Subscriber Driven Intelligent Access, announced that fast-growing Australia service provider Comvergence is successfully rolling out Calix AXOS solutions to businesses throughout Australia’s two largest cities. The first to deploy this groundbreaking technology in both Sydney and Melbourne, Comvergence is leveraging the Calix AXOS E5-16F Node inside multi-tenant unit (MTU) buildings and 801F GigaPoints at each premise to deliver symmetrical broadband speeds over the existing copper infrastructure of up to 300 megabits per second (Mbps), and the capability to deliver a true gigabit experience to each subscriber if required. Comvergence is also utilizing the Calix E7-2 Modular Access System for gigabit Ethernet backhaul over fiber.

Award-winning Calix Elite partner Optical Solutions Australia (OSA) played a key role in helping Comvergence leverage Calix anyPHY™ solutions to provide MTU-based small/medium sized businesses (SMBs), Australia Stock Exchange (ASX) listed companies, and government entities with the fastest broadband speeds over copper in the country – more than 12 times the speeds targeted by NBN Co. In addition, by leveraging SDN-optimized AXOS Activate software for end-to-end service turn-up and provisioning as well as leveraging existing in-building copper infrastructure, Comvergence can stand up new customers in a fraction of the time of its competition.

“Calix AXOS solutions gave us a powerful one-two punch in Australia’s two largest cities – the ability to stand out as the company capable of deploying not only the fastest and most reliable business services over copper in the market, but to do so in the shortest time from order to service delivery,” said Brian Michael, director at Comvergence. “Once live, Calix solutions have continued to allow us to distinguish our service with extraordinary always-on reliability and the ability to easily step-up to the increasing speeds demanded by our business customers. Given our success in Sydney and Melbourne, our next step is to pursue opportunities to extend the powerful Calix solutions in other opportunities nationally.”

Comvergence has already redefined the business market landscape in Australia’s two largest markets with Calix AXOS solutions. Next, this agile service provider stands ready to raise the competitive bar by potentially leveraging recent enhancements to the unrivalled Calix solutions portfolio, including copper bonding technology capable of doubling currently available broadband speeds over, and Calix Collective Dynamic Timing Allocation (cDTA) technology capable of dynamically reallocating both upstream and downstream bandwidth to enable maximum performance upstream and downstream.

“Service providers are constantly looking for innovative new ways to provide differentiated, cost-effective, fastest-to-market, and reliable services to their business customers,” said Joseph Haddad, vice president of international sales at Calix. “Historically, businesses residing in copper-fed MTUs were experiencing a digital divide – left behind as their competitors made the leap to higher speed services and performance. No more, as Calix AXOS innovations have allowed service providers like Comvergence to revolutionize their markets by leveraging existing copper infrastructure and stand apart from their competitors in agility, speed, and service quality.”


Sckipio Demonstrates 750Mbps Upload Speed over Twisted Pair

 Las Vegas, NV, Consumer Electronics Show, January 5, 2016 – Sckipio Technologies, the leader in, today announced it is demonstrating over 750Mbps of ultrafast broadband upload speeds on existing twisted pair copper telephone wires — over 100 times faster than most consumers achieve today.

This breakthrough performance will allow telcos worldwide to dramatically improve consumer experience with the many new consumer services and devices being announced at CES. In October of 2015, Sckipio previously demonstrated overall download and upload speeds of over 1.5Gbps by bonding two phone lines together — a highly attractive solution for operators in North America and Taiwan.

At today’s upload speeds, it’d take the average broadband subscriber over five hours to upload a 30-second full-resolution, GoPro 4K video to YouTube — the same amount of time it would take to fly from Los Angeles to New York City. With the solution from Sckipio, consumers could upload the same video in 2.5 minutes — less time than it would take to brew a cup of coffee.

“Most DSL and cable broadband technologies are unable to provide a higher ratio of upload to download speeds — making it very challenging to deliver next generation consumer services,” said David Baum, CEO of Sckipio Technologies. “Since user-generated content has increasingly become important, having fast upload is critical and this is a big advantage of”

The solution is the world’s fastest implementation of and it helps telcos compete very effectively against cable operators using DOCSIS 3.1.

I’m still working through remarkable presentations from the Broadband Forum events. Michael Weissman, Bernd Hesse and team did a remarkable job choosing the speakers.

Deutsche Telecom: 35b Supervectoring Delayed to 2019
Broadcom is now over 3 years late. DT briefed German reporters after their financial call and revealed 35b was now delayed until 2019. 35b should deliver 200+ meg downloads 500-600 meters, a crucial tool for DT, which is losing share to cable. Cable now covers about 70% of Germany and is expanding. DT now only offers 50-100 megabit DSL while cable is often 400 megabits, going to a gigabit. 

The problem is software; the hardware is shipping and supposedly will work. DT says 35b is not ready to turn on. Broadcom in 2015 said 35b was in "production" in the press release below. Alcatel in early 2016 said to expect complete systems very soon. "35g is very similar to 17a so there should be little delay."

Broadcom's problems are leading major telcos and vendors to have a plan B, using Sckipio DT itself is planning extensive deployments in 2019, mostly in apartment buildings.

Gigabit 100 Meters - Unless the Wires are Lousy
Speeds are fine, "Unless there's a line problem." I've been reporting for three years that ~10% of lines have problems. In the chart by Rami Verbin of Sckipio, he finds goes ~130 meters on good lines. Poor lines have about half the reach. 

His chart roughly matches the reports from Swisscom, Belgacom, and England for both & vectored DSL. The 10% with problems can cause the majority of the line-related complaints to support. The angry customers drive up cost.

Rami's solution to reach the gigabit is bonding, supported on the Sckipio chips. Verbin made some additional points:

  • 4 gigabits is possible by bonding two decent 2 gigabit lines.
  • Even in a service from remote cabinets, ~25% are close enough to get a full gigabit."
  • cDTA and iDTA are practical ways to deliver much higher upstream by switching some bandwidth from downstream to upstream only when needed.
  • 35B will probably be similar but Deutsche Telecom doesn't expect to deploy until 2019.

AT&T Wants Coax 2-5 Gigabit Very Soon.
AT&T faces intense competition from cable, talking about 10 gigabits in both directions. (Cable will only be 1 gig down, ~100 meg up, until ~2021.) AT&T wants something to brag about as well.

AT&T gained millions of lines of coax as part of the DirecTV deal. Alcatel and Huawei are leading the development of G.mgfast. That uses 424 MHz, full duplex, to achieve ~2.5 gigabits in both directions. The reach on telco twisted pair is only about 30 meters. On coax, those speeds can probably extend far enough to service most apartment buildings. Using 848 MHz, speeds can reach 5 gigabits. The ITU standards group has been aiming for 2019-2020 for G.mgfast, too slow for AT&T's marketers. David Titus wants a high-speed standard for coax "early in 2018." He believes that is "doable."
