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 (G.fast) 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."

ASSIA Wins Judgment Against BT on Dynamic Spectrum Mgt

The UK Court of Appeal in London affirmed a 2013 High Court judgment in favor of ASSIA on one important broadband management patent and determined that British Telecom infringes a second, more fundamental patent covering dynamic spectrum management techniques.

ASSIA said the Court of Appeal judgment holds that BT infringes two key ASSIA patents in its management of the rapidly growing “Next Generation Architecture” UK superfast broadband network. ASSIA’s patents at issue in the trial describe sophisticated techniques for rapidly optimizing millions of broadband connections without human intervention.

According to a recent BT announcement, 203,000 new customers subscribed to the operator’s superfast broadband offering between July and September 2014, bringing the total number of BT superfast broadband customers to 3.3 million as of September 30.

“Today’s ruling affirms ASSIA’s role as an innovator in the field of broadband performance optimization,” said ASSIA General Counsel Noah Mesel.  “Two dozen major operators around the world license our products because they recognize the significant value ASSIA’s software uniquely adds to their businesses.  As BT continues to grow the part of their business that infringes ASSIA’s patents, it is time for them to join companies such as AT&T, Verizon, Sky, and Bouygues, and license our software; otherwise BT should pay for infringing our patented technology.”

ASSIA and Lantiq Sign Vectored VDSL Cross-license Deal

Lantiq and ASSIA Inc. announced a collaboration and cross-license agreement for the management of vectored systems.

Lantiq has shipped nearly two million vectored VDSL ports to its DSLAM vendor customers.

ASSIA’s DSL Expresse management software manages approximately 20 percent of all DSLs worldwide.

The companies said the combination of ASSIA's DSL Expresse Smart Vectoring management software with Lantiq vectored VDSL chipsets enables broadband service providers to automatically plan, predict, manage and optimize the performance of their vectored VDSL networks, thereby ensuring the best possible customer experience and maximizing their return on investment.

“By collaborating with ASSIA, we expect to leverage the full benefits of vectored VDSL, regardless of deployment scenario, and to set the highest standards for product performance for our customers,” said Lantiq CEO Dan Artusi. “The agreement also assures substantial IP protection for customer deployments based on Lantiq chipsets and ASSIA software tools.”

“ASSIA is delighted to be working with Lantiq on the products and solutions that make the deployment and management of vectored VDSL networks easier and faster,” said ASSIA CEO and Chairman, Dr. John Cioffi. “As a result of this agreement, service providers worldwide have the opportunity to improve customer experience and economically deliver high-performance broadband services to the digital home.”

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.”

Telefónica Leverages ASSIA's DSL Expresse for Real-time Copper Line Optimization

Telefónica will expand its usage of ASSIA's DSL network management technology to cover more than eight million customer lines globally, and will initially focus on South American countries, including Argentina, Brazil, Chile, Colombia, and Peru. ASSIA is also a portfolio company of Telefónica. An initial contract was signed in 2010.

Telefónica plans to deploy ASSIA's DSL Expresse real-time line optimization module for proactive line repair, and ClearView, a customer-care recommendation engine that presents comprehensive customer line and service information to customer-care professionals through an easy-to-use interface, enabling them to provide the fastest-possible responses and resolutions to customer calls.

“We are pleased to incorporate the latest DSL Expresse features, which reinforce the value of our operations and technical assistance tools in improving service performance and customer care, as well as reducing our maintenance costs,” said Enrique Blanco, global CTO of Telefónica. “The improvements that we have realized with ASSIA for the past three years since we first invested in them clearly justified the expansion of our relationship as we continue to focus on delivering the highest speeds and latest services to our customers.”

Under the deal, ASSIA will provide Telefónica with the following advanced features of DSL Expresse and services for deployment, training, support, assessment and maintenance:

  • ClearView, a state-of-the-art expert system that tracks problems to their exact source and provides clear and concise recommendations to a contact center agent or field technician to resolve a customer DSL issue immediately.
  • Real-time line optimization, which significantly improves customer satisfaction and reduces service calls and repair costs.
  • Support for single-ended loop test (SELT) for enhanced diagnostics, cost savings, and service delivery, such as the ability to pinpoint faults and direct dispatches to the appropriate location.
  • Advanced micro-filter detection, which enables call-center agents to see missing micro filters on customer lines and guide the customer to easily and quickly install them. This can rapidly help solve performance problems, avoiding the need for costly, time-consuming field-technician dispatches.
  • Power management, which reduces power consumption and costs, and can help Telefónica attain its green initiative goals.
  • Advanced ADSL2 diagnostics that enable service personnel to address physical impairments efficiently in the copper plant.
