Lucent 56Kbps Chips, 3Com Modems Now Interoperable Newsbytes - March 03, 1998 15:16 ALLENTOWN, PENNSYLVANIA, U.S.A., 1998 MAR 3 (NB) -- Newsbytes. After announcing an initiative last January to make sure their modems would "talk" to each other, Lucent Technologies [NYSE:LU] said its 56 kilobits per second (Kbps) V.90 standards based modem chips will now interoperate with modems from 3Com [NASDAQ:COMS]. In tests conducted by Lucent and 3Com, connections between products from the two companies were achieved at 50 Kbps under a variety of telephone line conditions. Tests between Lucent's and 3Com's products were "exhaustive," a Lucent Microelectronics Group official said, and covered "every phase of modem start-up procedures." When the Lucent/3Com testing plan was first announced, Bob Rango, Lucent general manager of modem integrated circuits for Lucent's Microelectronics Group, said that his company looks at the interoperability testing as "the first step towards creating a marketplace that's based on the (new) standard" (Newsbytes, Jan. 20, 1998). Lucent said it plans to begin shipping V.90-compliant software code this month. Modems that have already been manufactured with Lucent chips are easily upgradable via software to the new standard. New modems equipped with Lucent chip sets will contain both the K56flex proprietary technology the company developed with Rockwell Semiconductors and the V.90 modulation schemes. Having both technologies onboard will allow users to connect to the Internet at data rates up to 53Kbps -- the fastest currently allowed by the US Federal Communications Commission (FCC) -- regardless of whether their Internet service provider (ISP) has deployed V.90 or K56flex equipment. Last February, 3Com and Rockwell Semiconductor Systems -- Lucent's K56flex partner -- announced that they had successfully completed interoperability testing of their respective V.90-based 56Kbps modems (Newsbytes, Feb. 17, 1998). The new V.90 technical specification, approved last month by the International Telecommunications Union (ITU), is described by modem makers as a mix of K56flex and 3Com-developed x2 technologies (Newsbytes, Feb. 5 and 6, 1998). The new spec uses the digital connections found at the ISP end to boost modem speeds coming from the ISP to the consumer to as high as 53Kbps. The "upstream" path, or the speed achieved from the consumer's PC to the ISP, can go as fast as 33.6Kbps. The high-speed 56Kbps analog technology works best with applications that need fast downloading speeds like surfing the Internet, Newsbytes notes. Applications like videoconferencing, which needs a fast dual- directional path, are better suited for technologies like integrated services digital network (ISDN). ITU's next step for the new 56Kbps standard is to formally ratify it at another meeting this September. But the final vote is usually just a formality, experts have said. 3Com also announced it was making available its V.90 upgrades for x2-based modems, which Newsbytes covered earlier Tuesday. Upgrades can be downloaded from 3Com's Web site, at 3com.com . Newsbytes notes that not all 3Com US Robotics modems can be upgraded to V.90 by a simple software download. Factors that can affect upgrades include whether the modem is an internal or external model, whether it includes voice capabilities and when the modem was made.Also, some upgrades are still being developed, one 3Com source told Newsbytes.
