Bell Labs HolmdelBT decides to stick with the big guys. Alcatel-Nokia and Huawei have been #1 & #2 in DSL for a decade, both with excellent products. They both jumped in early to G.fast and their gear works well. They've now won the next stage of BT's 10M home servable G.fast offering, another 100,000 homes in the next six months.  BT's Seeley is hopeful they will get production amendment 2/3 chips, but their main supplier Broadcom is not committed to delivering the chips so soon. 

Ray Le Maistre, a first rate British reporter, believes Adtran has a chance to get back in at the next stage of DSLAM procurement. No word yet on which modems will be used. Arris/Pace and Technicolor are hopeful. Nokia and Huawei do not generally build their own modems, I believe, but instead OEM them. BT may be willing to pay the markup for now. There's still plenty of system work to do and they are sensibly cautious.

BT has surprisingly few choices. The vendor community has shrunk drastically. I know only four DSLAM makers and two chip vendor likely to be ready to serve a customer like BT.

 Very few companies have come to market with either chips or DSLAMs; Le Maistre only sees the three above and Calix as viable choices. I've reached out to ZTE and Zyxel, but haven't heard much from them. On the chip side, I haven't heard anything from Realtek, Metanoia, HiSilicon or Triductor; all had been interested in making G.fast chips. If you're a manufacturer ready to deliver G.fast equipment, please get me the information.

AT&T is addressing the problem of fewer vendors by doing more of their own R & D. They have a huge team working on Software Defined Networking and are major contributors to Open Source software. They also built their own DSLAM for SDN testing. BT, especially Trevor Linney, has taken a key role in the design of the standard, backed by essential research.

Telcos worldwide are now paying the price for two decades of cutting back R & D.

Openreach selects Huawei and Nokia to support its ultrafast broadband roll-out

Press Release  •  Sep 22, 2016 14:37 BST

Openreach has chosen two of the world’s leading communications technology companies, Huawei and Nokia, to provide a range of equipment in support of its ultrafast broadband roll out across the UK.

The companies, which have been working with Openreach on the world’s largest trials of ‘G.fast’ technology in Huntingdon, Gosforth and Swansea, will provide cutting edge switches, modems and cabinet ‘side pods’ to help deliver download speeds up to 330Mbps – more than 20 times the current UK average – to 10 million homes and businesses by the end of 2020.

The new kit will be rolled out in parts of Gillingham and Cherry Hinton later this year and will help Openreach deliver its ambition of getting ultrafast broadband of at least 100Mbps to 12 million premises in the same timeframe, and the majority of the UK by the end of 2025.

Clive Selley, Openreach CEO, said: “Openreach is pioneering G.fast technology because we want to get affordable ultrafast speeds to as many people as possible in the fastest possible time.

“We also want to deliver this next generation of broadband services in the most efficient and least disruptive way – so it is a testament to our world leading R&D team that they’ve managed to define and drive new standards with operators and equipment manufacturers around the globe.

“This country already has the best superfast broadband coverage and take-up amongst the big economies in Europe, and we want to repeat that success with ultrafast. We’ll be going flat out to reach 12 million homes by 2020 and we are really leading the way by bringing cutting-edge kit to the UK at a huge scale.”

Jeff Wang, president of Huawei Access network, said: “Huawei has been working with Openreach for many years and we are looking forward to continuing the partner relationship through the G.fast contract. Huawei’s investment and innovation in G.fast will help Openreach to deploy ultrafast broadband from the street cabinet instead of the distribution point, making the business case viable for a large scale rollout and accelerating the rollout speed.”

Cormac Whelan, CEO Nokia UK and Ireland said: “Openreach’s selection of Nokia is a testament to excellent performance in the trials underlined by our world class vectoring capability. We know that G.fast is the key to quickly rolling out ultrafast broadband. We’re excited about our cooperation with Openreach and are confident that our innovation, strength and operational expertise will benefit all broadband subscribers in the UK.”

Today, more than 91% of homes and businesses in the UK have access to superfast speeds of 24Mbps and above, whilst the Openreach fibre network is available to more than 25 million homes and businesses. More than 100 different communications providers (CPs) are offering services over the company’s open wholesale fibre network, and all CPs will have access to these new ultrafast services under the same terms, conditions and pricing.

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
