6/15/2004 - Texas Instruments Incorporated (TI) (NYSE: TXN), a world leader in DSL, is unveiling a new high-bandwidth DSL technology that is backwards compatible with operators´ current infrastructure and will make it possible to add competitive video service revenue to their existing data and voice services. TI´s Uni-DSL (UDSL) technology raises the bandwidth of DSL to the level necessary to deliver High Definition Television (HDTV) and other advanced video services, as well as voice and data, throughout the home with limited fiber deployment. The backwards compatibility of UDSL-based equipment will allow operators to affordably deploy a flexible menu of services using ADSL and VDSL standards from a single line card design in the central office or residential gateway in the home. TI plans to take its vision of a universal DSL technology before the various standards organizations around the world to gain support for Uni-DSL technology.
UDSL-based equipment will be targeted at neighborhood service cabinets, sometimes called cross connects or primary connection points that are located four to six kilofeet (Kft) from the user. Operators can then deploy fiber to this connection point and utilize the existing copper to deliver speeds between 50-100Mbps to users. This will eliminate the need to deploy fiber to the home or the curb and still enable operators to deliver the speeds required to provide multiple high definition video streams to consumers. UDSL can also be used in multi-dwelling units (MDUs) and multi-tenant units (MTUs) in shorter loop markets where operators have already deployed fiber to the curb (FFTC) or building (FTTB) networks.
"Video services are the next opportunity for DSL service providers for additional revenue streams. TI's Uni-DSL proposal enables operators to provide video, VoIP and data services with limited fiber investment and maintain backward compatibility to existing ADSL equipment in the field," said Steve Rago, principal analyst, iSuppli.
The UDSL approach and technology will support ultra-high speed rates of 200Mbps aggregate throughput for one line of DSL, which can be used to provide 100Mbps symmetric or an asymmetric service, such as 150Mbps downstream-50Mbps upstream in shorter loops. Additionally, since UDSL is backwards compatible with all DMT standards, (ADSL, ADSL2, ADSL2+ and VDSL, as well as the upcoming VDSL2 standard) operators will be able to support multiple DSL service options using one solution. This compatibility provides capital expenditure savings across their entire network. UDSL also allows operators to keep pace with expanding technologies, delivering today's ADSL standards while providing the option to upgrade to video services once their business models are in place.
"Video is the next big growth opportunity worldwide for the entire DSL market from technology and equipment providers to operators. The UDSL architecture enables operators to deliver triple-play services for voice, video and data to consumers while saving capital expenditures throughout their network since it supports all ADSL and VDSL standards and requires limited fiber investment," said Joseph Crupi, vice president of TI's Broadband Communications Group.
UDSL in Short-Loop and Long Loop Markets
In short-loop markets found in both Asia and Europe, UDSL will provide bandwidths up to 200Mbps aggregate to deliver multiple channels of high definition video like HDTV. As the industry has seen with VDSL, TI expects that short loop markets will also adopt video over DSL and high-bandwidth services more rapidly than in longer-loop markets. This is because shorter loops enable higher bandwidths allowing for VDSL-type delivery with additional infrastructure build-out.
In long-loop markets like in the United States and parts of Europe, the ultra-high speed bandwidths provided by UDSL require additional infrastructure into neighborhoods such as fiber. The benefit of UDSL in longer loop markets near-term is that it provides highly upgradeable technology. Operators can deploy UDSL-based equipment in their infrastructure in places such as the cross connect and support ADSL, ADSL2 and ADSL2+ services and then be able to upgrade to 100Mbps and VDSL2 speeds when their infrastructure is ready. Operators will also be able to take advantage of economies of scale by having large portions of their network based on UDSL to support all of their network environments and customer services.
TI expects to introduce its first UDSL solutions next year. UDSL-based equipment is expected to begin rolling-out in 2006 to deliver ADSL-, VDSL- and ultra-high speed services to consumers.
