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."
