ASSIA envisions Terabit DSL

Dr. John Cioffi, Chairman and CEO of ASSIA and Professor Emeritus at Stanford, will present a vision for delivering terabit-class connectivity over twisted pair copper lines in the home.

This fiber-like speed could be enabled by leveraging previously-unexploited waveguide modes of current copper infrastructure coupled with ASSIA's vectored transmission capability.

In a presentation at this week's TNO Ultra-fast Broadband Seminar in The Netherlands, Dr. Cioffi will explore how vectored waveguide-mode use of copper phone lines is similar to 5G wireless's Massive MIMO use of millimeter-wave transmission.  He will also discuss how waveguide modes use frequencies above 100 GHz to enable extraordinary speeds.

When deployed, these extremely high-frequency millimeter and sub-millimeter waves hold the possibility of increasing single-line data rates to terabits/second at 100-meter lengths on ordinary twisted pair phone wire.  Speeds of 100 Gbps could be achieved at distances over 300 meters, and speeds of 10 Gbps could be achieved at distances over 500 meters.

During this presentation, Dr. Cioffi will explain how 5G wireless often runs at 28 GHz and 39 GHz, while commercial microwave gear can run at 70 GHz and 90 GHz.  Wireless transmission above 300 GHz (sub-millimeter wave) is being actively researched.  Cioffi explains, "Early designs suggest link latency of 50-100 microsec is readily achievable, which would easily allow even the most stringent 5G latency specifications of 1ms or less to be achieved with Terabit DSLs."

Today's fastest DSL ( uses only 200 MHz of bandwidth, while wireless uses 25 times as much spectrum. Dr. Cioffi notes, "by working with my ASSIA colleagues Dr. Chan Soo Hwang, Dr. Ken Kerpez, and Dr. Ioannis Kanellakopoulos, we found a solution that uses higher frequencies over wires."

Broadcom Adds Noise Cancellation to DSL Gateways

Broadcom is adding a Reference Noise Cancellation (RNC) technology to its BCM63138 family of devices . Broadcom is the first to offer telecom carriers the benefits of RNC to enhance the performance of DSL customer premise equipment (CPE) without the need to replace or upgrade installed ADSL or VDSL2 infrastructure equipment. For more news, visit Broadcom's Newsroom.

Broadcom's RNC implementation on its BCM63138 family of high-performance DSL SoCs for home gateways works with existing DSL infrastructure equipment, including single-line or bonded ADSL and VDSL. It also complements existing DSL performance techniques such as G.inp, and G.vector, and coexists independent of any other equipment in the network. By filtering out received noise on the subscriber line at the CPE in the residence, this advancement in DSL technology enables carriers to improve the quality of the received signal and deliver higher performing broadband to subscribers.

"Today's announcement builds on Broadcom's unmatched DSL portfolio, enabling operators to deliver high-bandwidth broadband services to meet growing consumer demand," said Greg Fischer, Broadcom Senior Vice President and General Manager, Broadband Carrier Access. "With the addition of RNC technology to Broadcom's BCM63138 SoC family, operators can deploy CPE that provide DSL subscribers with an unmatched performance improvement with no investment or change to existing installed infrastructure equipment."

FCC Updates Broadband Definition to 25 Mbps

The FCC updated its definition for broadband to 25 Mbps down and 3 Mbps up.

The previous benchmark, set in 2010, was 4 Mbps down and 1 Mbps up.

The FCC also released the following stats on broadband adoption:

  • 17 percent of all Americans (55 million people) lack access to 25 Mbps/3 Mbps service. 
  • 53 percent of rural Americans (22 million people) lack access to 25 Mbps/3 Mbps. 
  • By contrast, only 8 percent of urban Americans lack access to 25 Mbps/3 Mbps broadband.
  • Rural America continues to be underserved at all speeds: 20 percent lack access even to service at 4 Mbps/1 Mbps, down only 1 percent from 2011, and 31 percent lack access to 10 Mbps/1 Mbps, down only 4 percent from 2011.
  • 63 percent of Americans living on Tribal lands (2.5 million people) lack access to 25 Mbps/3 Mbps broadband
  • 85 percent living in rural areas of Tribal lands (1.7 million people) lack access.
  • 63 percent of Americans living in U.S. territories (2.6 million people) lack access to 25 Mbps/3 Mbps broadband.
  • 79 percent of those living in rural territorial areas (880,000 people) lack access.
  • Overall, the broadband availability gap closed by only 3 percent last year.
  • Americans living in rural and urban areas adopt broadband at similar rates where 25 Mbps/ 3 Mbps service is available, 28 percent in rural areas and 30 percent in urban areas.
  • Approximately 35 percent of schools lack access to fiber, and thus likely lack access to broadband at the Commission’s shorter term benchmark (adopted in its July 2014 E-rate Modernization Order) of 100 Mbps per 1,000 users, and even fewer have access at the long term goal of 1 Gbps per 1,000 users.

ASSIA Prevails in Patent Case Versus BT

The High Court of Justice in London ruled that two patents on DSL management technologies held by ASSIA are valid and that British Telecom infringes one of the patents. The court determined that BT uses ASSIA’s patented DSL management technology in BT’s Next Generation Access (“NGA”) network.

The two patents in the case, EP (UK) 1,869,790 and EP (UK) 2,259,495, describe inventions fundamental to dynamic monitoring and automatic optimization of DSL networks.

"As a software developer, ASSIA’s principal business is to deliver our award-winning products and services to customers,” ASSIA CTO Marc Goldburg said.   “We attempted for years to work with BT in this spirit.    When it became clear that BT was using ASSIA’s technology without a license and was not willing to license ASSIA’s technology or products, it became necessary to bring this patent infringement claim.”

Tollgrade Launches "Virtual Broadband Technician" CPE

Tollgrade Communications introduced a "Virtual Broadband Technician" (VBT) customer premise device for diagnosing slow broadband connections.

The device can be used to pinpoint problems like intermittent faults, noise on the line and unresolved line speed instability.  The VBT is placed in line with the residential DSL modem.  It then performs a series of 50 tests, and can diagnose the cause of the problem – whether it lies within the customer premises (e.g., electromagnetic interference in the home) or anywhere in the local access network.

Tollgrade said its data from VBT field deployments found that 82 percent of tested customer premises equipment (CPE) would have been returned unnecessarily had it not been for the diagnostic capability of the VBT. By correctly pinpointing problems inside the home that would otherwise have been left undiagnosed, the VBT reduced repeat dispatches by over 50 percent, saving millions and reducing customer churn.

AT&T Expands Coverage of 45 Mbps U-verse Internet Service

AT&T has expanded its U-verse Internet service, offering speeds of up to 45 Mbps downstream and up to 6 Mbps upstream, coverage to 40 new markets across 15 states.

AT&T's expansion of faster U-verse Internet speeds is part of the company's Project Velocity IP (VIP), a three-year investment plan announced last fall to expand and enhance its IP broadband networks. AT&T plans to upgrade top tier U-verse speeds to up to 100 Mbps in the future.

  • On November 7, 2012, AT&T unveiled Project Velocity IP (VIP) -- its plan to invest $14 billion over the next three years to significantly expand and enhance its wireless and wireline IP broadband network. The plan adds $8 billion for wireless initiatives and $6 billion for wireline initiatives.  It also makes a distinction between areas where the company believes are better served wirelessly rather the through a traditional copper network or deploying a fiber infrastructure.
  • Total capital spending is now expected to be approximately $22 billion for each of next three years. The company said a stronger balance sheet has provided it the financial footing to invest. AT&T is also increasing its quarterly dividend 2.3 percent and is predicting EPS will grow by mid-single digits for the next 3 years with opportunity for stronger growth going forward.
  • The Project VIP plan includes an upgrade for U-verse to speeds of up to 75Mbps and for U-verse IPDSLAM to speeds of up to 45Mbps, with a path to deliver even higher speeds in the future.
  • In the 25 percent of AT&T's wireline customer locations where it's currently not economically feasible to build a competitive IP wireline network, the company said it will utilize its expanding 4G LTE wireless network -- as it becomes available -- to offer voice and high-speed IP Internet services. The company's 4G LTE network will cover 99 percent of all in-region customer locations. AT&T's 4G LTE network offers speeds competitive with, if not higher than, what is available on wired broadband networks today.

    Ikanos Demos VDSL at 300 Mbps over 200m

    Ikanos Communications has achieved an aggregate throughput of 300Mbps over a standard single-pair copper cable up to a distance of 200 meters (short-loop) using its existing VDSL chipsets.

    Ikanos described the short-loop demonstration as a significant step towards G.Fast.

    The demonstration follows recent, multiple top-tier OEM and carrier lab trials in which the company’s Velocity-3 central-office (CO) chipset was been given high marks for achieving 150Mbps aggregate throughput (110Mbps downstream and 40Mbps upstream) at a distance of 500 meters in a 192-port reference DSLAM system.

    “Ikanos has a history of challenging the industry by pushing the performance envelope and continuing to raise the bar on our competition,” said Kourosh Amiri, vice president of marketing at Ikanos. “With Velocity-3, in a matter of a few months, we have received widespread recognition of our industry leadership in performance and scalability for high-port-count deployments of 192 lines (scalable up to 384), at distances reaching 500 meters and beyond.  While the G.Fast promise of gigabit performance is still on the horizon, our ability to demonstrate hundreds of megabits for lower-port-count short-loop configurations using our currently shipping CPE and CO silicon establishes Ikanos as the leader in the ‘pre-G.Fast’ era, as we enable telcos to remain competitive against mounting pressure from MSOs and continue to enhance the consumer DSL broadband experience.”
