Telebyte-Gfast-BBWF2016-320-px-wideBroadcom, Metanoia, and Sckipio chips communicate. For more than a decade, the industry has come together at the University of New Hampshire to confirm chips work well together. No standard - even the 300 pages of - covers everything. No company is likely to include everything in those 300 pages. But they have to work well in the field. A gateway with a Metanoia chip needs to connect robustly with a DSLAM with a Broadcom chip. Customers hate to be locked into a single source so demand vendors solve the problems.

Live at the Broadband World Forum, the major vendors connected their gear and a Telebyte tester (pictured.) They've been meeting regularly at the new lab at UNH; all report progress but there's still much work to do. Additional plugfests were scheduled for November and January.

Top Companies Partner with UNH-IOL to Showcase Live
Interoperability Demo at Broadband Forum 2016

DURHAM, N.H.--()--The University of New Hampshire InterOperability Laboratory (UNH-IOL), an independent provider of broad-based testing and standards conformance services for the networking industry, is excited to partner up with six companies to showcase the industry's first cross-chipset interoperability demo at this week’s Broadband World Forum (BBWF) taking place at the ExCeL Convention Centre, Royal Victoria Dock, London at booth (D30). Companies include CalixDigital Lightwave (A Division of VeEX); HuaweiMetanoia Communications, Inc.Technicolor; and Telebyte.


UNH-IOL is hosting a multi-vendor demonstration highlighting the interoperability of products from the previously mentioned companies based on chipsets from three different providers, Metanoia, Broadcom, and Sckipio. There is a massive increase in live deployments of across the world and proving the importance of interoperability with help showcase equipment and solutions from top vendors.

Selected in 2014 as the Broadband Forum’s first and only official test site for the Certification Program, the UNH-IOL has worked with the chipset provides, device manufacturers, and Service providers to create a vibrant ecosystem of manufacturers and support the accelerated adoption of the standard by Service providers. Having hosted several plugfest events over the past year, this interoperability demo is the first public outcome of those events. The upcoming plugfests, scheduled for November and January will continue to the development of interoperable solutions, creating more flexible, harmonious networks which helps save money for Service providers and accelerate time to market.

Executive Comments:

“Being part of this Cross-Chipset Interoperability Demo as a CPE provider is an exciting experience for us. IOP is critical to the market, and Metanoia recognized it from day one and has been very active not only in the Plugfest organized by UNH, but also in working with some major players in this new market.” - Metanoia Communications, Inc., CEO, CT Wu.

“It is very beneficial for the industry to see that interoperability is real,” said Michael Breneisen, President of Telebyte. “Knowing there are test solutions available that are designed specifically for physical layer testing makes it easier for companies to begin or expand their efforts in this area. Telebyte is excited to be leading the industry in providing those solutions.”

“As the technology has moved quickly from pilots and lab trials to real live deployments in 2016 the interoperability work of the UNH-IOL in partnership with the Broadband forum becomes more and more critical. We are proud to be working with them to assure the successful commercial viability of in multi-vendor environments.” - Calix

“With standardization completed, chipsets available, and huge appetite from operators, exciting times lay ahead with sizeable deployments forecasted for as early as 2017.” - Karel Adriaensen, Technicolor Connected Home Product Director.

“An Ethernet/IP traffic generator and analyzer is a critical component of the Broadband Forum’s ID-337 Certification Test Plan,” said Cyrille Morelle, President and CEO of VeEX.“The UNH-IOL Certification lab has adopted our MPA Multi-Protocol Analyzer and Generator as part of their testing service equipment. Digital Lightwave is ready to meet the crucial testing needs of the ecosystem.”

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."
