Ikanos Communications and ASSIA Inc., which specializes in Dynamic Spectrum Management (DSM) technology, announced a partnership to accelerate the deployment of vectored DSL technology.
Under terms of the agreement, Ikanos receives a license to ASSIA’s essential DSM patents and certain technology for the development of vectored DSL products — also known as DSM Level 3 — capable of delivering speeds of 100 Mbps and greater over existing copper loops. In addition, the two companies will co-market each others’ products to the network equipment and service provider industries.
DSM enables service providers to maximize the rate and reach of their DSL services, while minimizing operating costs, through the automatic optimization of DSL networks and advanced, root-cause diagnostics analyses. DSM Level 3 (DSM 3) techniques can enhance and extend very-high-data-rate DSL (VDSL) downstream data rates in excess of 100 Mbps and upstream data rates in excess of 50 Mbps for fiber-fed DSL access multiplexers (DSLAMs) in the neighborhood, at the curb and in the building. DSM technology also enables service providers to further extend the useful life of the copper infrastructure and compete effectively from a performance and economic perspective with more expensive passive optical networking (PON) and hybrid fiber coax (HFC) services.
DSM 3 is one of the three levels of DSM defined in the ATIS DSM Technical Report (ATIS PP-0600007) for managing noise, power and crosstalk in DSL systems of all types — ADSL1, ADSL2/2+ and VDSL — in both single service provider and unbundled, multiple service provider environments. Complementary standardization efforts have been completed in the ITU-T and the Broadband Forum, with ongoing standardization efforts underway for advanced DSM technologies.

- Adaptive Spectrum and Signal Alignment (ASSIA), which is based in Redwood City, California, is headed by Dr. John Cioffi, who served as founder, CTO and Vice President of Engineering at Amati prior to its acquisition by TI in 1997. Dr. Cioffi also held a tenured endowed professorship at Stanford University in the Department of Electrical Engineering from 1985-2009, where he is now an active Professor Emeritus with small research efforts there in broadband access.
