Lucent Technologies and 3Com Corporation, today announced a jointly-designed technical specification for interoperable Asymmetrical Digital Subscriber Line (ADSL) products and services based on the International Telecommunication Union`s emerging Discrete Multitone (DMT) standard. The companies are working together to ensure their current and future ADSL products and services work together based on the ANSI T1.413 Issue 2 specification for ADSL and, later this year, on the ITU G.dmt full-rate ADSL standard. Lucent and 3Com expect to incorporate sub-rate ADSL solutions. Both companies support the efforts of the Universal ADSL Working Group (UAWG) and expect to implement the ITU G.lite standard into their respective ADSL products and services. Ultimately, the companies anticipate that the jointly designed specification will lead the ADSL industry to interoperability. "Our customers have clearly said that interoperability is crucial to the deployment of ADSL products and services to the mass market," says Linda Manchester, director of ADSL business management and strategy for Lucent. "Our goal is to lead the industry to interoperability, and to quickly get ADSL products to market." Al Brisard, director of business development for 3Com`s xDSL group, said, "The interoperability work between 3Com and Lucent will move the market closer to completely ensuring end-to-end equipment compatibility. "We`re working closely with Lucent and other players to ensure that interoperability is eliminated as a concern to our mutual customers." 3Com offers a portfolio of consumer and business ADSL CPE products based on a common platform founded on a highly flexible and fully programmable Digital Signal Processor (DSP), explains 3Com SA`s regional director, Buddie Ceronie. "This architecture allows 3Com`s CPE to be readily modified and software upgraded for compliance with emerging standards," he says. "3Com`s approach ensures that customer investment in CPE products is safely retained by providing a migration path to determined industry standards for full-rate and sub-rate ADSL." He points out that 3Com`s commitment to this architectural approach is evident in the new OfficeConnect Remote 811 ADSL Router and single-user ADSL modems recently announced. "These products support full-rate ADSL and will fully support the G.lite standard. Today`s announcement further demonstrates Lucent`s and 3Com`s commitment to achieving interoperability with other major players in the ADSL market." Lucent`s interoperability efforts will cut across the company`s entire ADSL product portfolio, including previously announced partnerships and product development plans. The company`s portfolio will offer service providers ADSL products based on a common architecture for cost-effective, integrated and overlay solutions for communications service providers` central offices, 5ESS.-2000 AnyMedia Switches, SLC.-2000 digital loop carriers, SLC.-Series 5 digital loop carriers and remote offices. Lucent offers service providers flexible platforms that can be deployed within existing infrastructures to deliver full-rate and G.lite ADSL services to mass-market and high-end users on an incremental, on-demand basis without incurring huge equipment upgrade costs. The companies will be holding an interoperability demonstration at SuperComm `98 in Atlanta, taking place from June 9 to June 11. The demonstration will feature 3Com`s new OfficeConnect. Remote 811 ADSL router as well as Lucent`s AnyMedia FAST ADSL Application Pack integrated into Lucent`s 5ESS.-2000 AnyMedia Switch.
