Broadcom is now over 3 years late. DT briefed German reporters after their financial call and revealed 35b was now delayed until 2019. This was confirmed to me by Achim Sawall of Golem.de, a reporter I respect..

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 government is calling for gigabit fiber, but DT has financial limits that make that tough.

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."

Adtran, Huawei, and Nokia-Alcatel are all selling 35b DSLAMs. The common factor is the Broadcom chip.

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.

I've no information about whether Broadcom's large layoffs caused the delay.

 

Broadcom Raises the Bar for Ultrafast Broadband Copper Networks

Industry's First Commercial Silicon Support for New VDSL2 35b and G.fast Bonding Standards

 

LONDON, Oct. 19, 2015 /PRNewswire/ -- Broadband World Forum 2015 – Broadcom Corporation (BRCM), a global innovation leader in semiconductor solutions for wired and wireless communications, today announced VDSL2 35b and G.fast bonding support for two new protocols under development in the International Telecommunication Union (ITU). With support for these new standards, Broadcom is enabling DSL network operators with a long-term roadmap for competitive high-bandwidth services with minimal investment to their physical plants. For more news, visit Broadcom's Newsroom.

For operators with a significant investment in Fiber to the Cabinet (FTTC) architectures, the new 35b protocol is an optimal solution to leverage the benefits of VDSL2 vectoring at higher data rates.  By engineering the tone structure of 35b to remain consistent with the field-proven VDSL2 17a protocol, this new standard increases aggregate DSL performance by up to 100 percent, without disturbing widely-deployed G.Vector crosstalk cancellation technology.  Broadcom is the first commercial silicon supplier to support the new standard with an end-to-end solution in production today, via the previously-released BCM63138 integrated residential gateway and BCM65235 Central Office DSP.

"We are pleased to see the industry responding to operators' requests for a high-bandwidth roadmap for cabinet architectures, "said Greg Fischer, Broadcom Senior Vice President and General Manager, Broadband Carrier Access. "Broadcom's quick introduction of end-to-end technology in support of 35b will have a very meaningful impact in time-to-service for this important new protocol."

For operators working from a multi-dwelling unit (MDU) or distribution point unit (DPU) network architecture, the new G.fast protocol remains a compelling alternative to avoid or defer the expense of installing fiber directly to the home. To maximize the distance over which multi-gigabit copper services may be delivered, the ITU recently developed a multi-line bonding amendment to the G.9701 standard.  By aggregating multiple copper pairs into a single logical link, bonding provides a path to increase rates well beyond 1Gbps, an important objective for many providers in competitive broadband markets.  Broadcom is supporting an end-to-end solution for G.fast bonding utilizing the existing BCM65244 Central Office DSP with the newly-released BCM65249 bonded CPE PHY device.

"As customer appetite for gigabit broadband increases, we are looking at all available tools to economically deliver these service rates," said Mu-Piao Shih, Chunghwa Telecom President. "With Broadcom's strong commitment to the G.fast standard, including the new G.fast bonding standard, we are seeing the potential to deliver a cost-effective, long-term gigabit roadmap for copper networks."

Broadcom's BCM63138, BCM65235, BCM65244, and BCM65249 are all in production.

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
