Zynq 320Ethernity going for 48 port DSLAMs. You need a heckuva lot of processing power when you are pushing 10-20 gigabits through a DSLAM. The company has been supplying network/flow processors for Ethernet controllers and similar for more than a decade. 

Xilink's Zynq combines dual ARM cores for control with programmable gate arrays for the dedicated application. FPGA's can be extremely powerful today. A different "Xilinx 16nm FPGA packs 5.2 billion transistors to support seven programmable cores." Rick Merritt.

They are already working with TSMC for a 7nm chip, which may cost upwards of $100M to design. 

The chip can also be delivered in a lower power, lower cost version. Ethernity has a 2.7W  offering combining switch, traffic manager and CPU subsystem.

Ultralow Power DPU Platform on ENET for G.fast Market

Single Chip G.fast Scalable DPU Architecture by Ethernity Networks Tested for 16, 24 and 48

Port Platforms

14 July 2016, Lod, Israel – Ethernity Networks, the leading provider of Systems-on- Chip, announces successful tests of ENET38xxZ/99 platform for G.fast FTTdp deployments. The company has ported the popular ENET based flow processor SoC into Xilinx Zynq series to form the family of G.fast DPU switch controllers, addressing the needs of emerging broadband access residential applications. This market now requires flexible support of different bandwidth and reverse power feed of remote devices from the customer’s residential gateways, and ENETxxZ/99 was tested for reliable provision of such DPU features.

Ethernity’s ENETxxZ/99 family is scalable, with application ranging from the low-end and very low power FPGA to multiport G.fast chassis. The tests showed extremely low power consumption of 2.7W for SoC combining switch, traffic manager and CPU subsystem.

“Apart from the best price-per- port-per- power, Ethernity’s G.fast platform is ready for next generation software defined networking (SDN), supporting Hierarchical ACL and port virtualization within G.999.1 channelized interfaces, EFM bonding and MEF requirements.

We anticipate emerging challenges for broadband communications and provide our customers with the future proof solution”, – explains Eugene Zetserov, Ethernity’s AVP Business development.

Ethernity’s G.fast platform provides uplink connection to the service provider’s central office in the network from 2.5Gbps to 20Gbps, with 5Gbps to 40Gbps data throughput. 

ENETxxZ/99 family utilizes Xilinx Zynq series, and leverages the scalable architecture of ENET, the core product of Ethernity Networks. ENET supports advanced functionality matching Metro market requirements, microwave backhaul and novel NFV/SDN concepts, where functions can migrate to cloud platforms.

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. http://bit.ly/BBFBASE

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
