testtakerintec and Adtran have working parts for testing bonding. 35b uses double the spectrum for double the speed, 200+ megabits at 500 meters. It's not ready for the field yet, but test gear is now available from the German firm intec.  Look for them at the Broadband Forum Interop exhibit.

Jeff Waldhuter of Verizon told me not investing in testing was the biggest mistake they made in the early days of DSL. BBWF will also feature Lincoln Lavoie, who has led the UNH/Broadband Forum testing for years. You can now buy the testing software they use for your own work. UNH uses Telebyte hardware, who will speak at the show. 

Does quality matter? Gordon Moore says Intel lost the battle for memory chips because the Japanese had better quality. Intel was shipping perhaps 1 bad part in 1,000. He says the Japanese were closer to 1 in 1,000,000, possibly exaggerating. From Moore's Law by Arnold Thackray.

Promised for 2016, Deutsche Telekom now says 35b will not be available until the second half of 2018. Since samples are being tested, perhaps they can beat that schedule. 

First VDSL tester for profile 35b bonding: intec presents new ARGUS models at the Broadband World Forum Berlin

Lüdenscheid, Germany, October 2017 – intec Gesellschaft für Informationstechnik mbH, German innovation leader in the field of telecommunications measuring instruments, will present high-grade new ARGUS brand test devices at the Broadband World Forum (BBWF) in Berlin, Europe’s most important industry event for broadband internet and telecommunication.

With over 25 years of experience, intec is one of Europe’s leading vendors of combined telecommunications measurement technology (xDSL, Ethernet, fibre, ISDN and more) designed specifically for use by network operators.

In Berlin, Germany’s market leader will present important new additions to the ARGUS family, including the only tester on the market that combines G.fast, VDSL2 profile 35b bonding, SHDSL and Gigabit Ethernet. The ARGUS family products cover all technologies currently deployed on the market – including, but not limited to ISDN, E1, POTS, ADSL2/2+ and VDSL2 vectoring as well as GPON, LTE and WLAN. 

“The transition to all-IP is in full swing – and presents new challenges for measuring technology. Made in Germany, our ARGUS testers offer solutions for all test scenarios and are unique in their superior performance, flexibility and multifunctional capability,” stated Dr Ralf-Dieter Heil, International Sales Manager at intec. “There’s a reason why major network operators and providers choose to depend on our products.”

Deutsche Telecom: 35b Supervectoring Delayed to 2019 http://bit.ly/35blater
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 G.fast. DT itself is planning extensive G.fast deployments in 2019, mostly in apartment buildings. http://bit.ly/35blater

Gigabit 100 Meters - Unless the Wires are Lousy http://bit.ly/gflousy
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 G.fast 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 G.fast & 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. http://bit.ly/gflousy

AT&T Wants Coax 2-5 Gigabit G.fast. Very Soon. http://bit.ly/ATTCoax
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."http://bit.ly/ATTCoax
