Ubiquitious DSL Deployment Now Possible With Highly Integrated Digital Loop Carriers. February 8, 1999 -- The Digital Subscriber Line (DSL) market just got another boost today by way of Digital Loop Carriers (DLCs). Centillium Technology Corporation announced that Advanced Fibre Communications®, Inc. (AFC) has selected the Centillium CopperLite chipset for the G.Lite ADSL (G.922.2) plug-in card for AFC's flagship product, the UMC 1000 Multi-Service Access Platform. As a leading manufacturer of networking equipment for the "local loop'' between telephone service users and public telephone networks, AFC's adoption of the Centillium CopperLite chipset is expected to enable telecommunications carriers to deploy low-cost, high-performance DSL services to worldwide markets more rapidly and cost-effectively than ever before. DLCs are quickly becoming the prevalent technology for delivering voice and data services over "last mile copper networks'' in every part of the world. In the United States, greater than 20% of local telephone lines terminate in a DLC, including up to 70% of all new line growth. Until now, however, carriers have been unable to cost-effectively deploy DSL line cards in remote cabinet DLCs due to severe power, rack space, and temperature constraints. The UMC 1000 from AFC overcomes these challenges with G.Lite DSL plug-in cards based on the CopperLite chipset. The Centillium chipset supports the industry's highest port density -- up to eight DSL ports per chipset -- enabling AFC to provide more DSL lines using less rack space in a small DLC. The CopperLite chipset also eliminates costly infrastructure upgrades by offering the industry's lowest power consumption (0.65 watts/per port) and ensures software upgradability over time by delivering ample processing power. "Both large and small telephone companies worldwide tell us that speed and profitability are critical to their success in deploying DSL services,'' said Philip Yim, Director, Product Planning, AFC. "To achieve rapid deployment of DSL in the local loop, carriers must be able to upgrade their existing infrastructure instead of building an entirely new one. AFC is committed to providing solutions compliant with the emerging G.Lite standards, which will accelerate and ease deployments of ADSL services. This new solution from Centillium and AFC allows carriers to leverage their installed base of existing equipment simply by adding new G.Lite DSL plug-in cards to their DLCs.'' "The power, temperature, and rack space requirements are far more limiting for a DLC in a remote cabinet than for a DSL Access Multiplexer in a central office,'' said Al Gharakhanian, Director of Marketing for Central Office Products, Centillium Technology. "The highly integrated CopperLite chipset, combined with the innovative and flexible architecture of AFC's UMC1000 platform, has removed one of the last barriers to mass deployment of DSL technology in both DLCs and central offices.'' Centillium CopperLite Delivers DSL in Digital Loop Carriers The two-part CopperLite CO (central office) chipset consists of the CT-L10DC08 Digital chip and CT-L10AC08 Analog chip. Networking equipment manufacturers can use these cost-effective, power-efficient chip sets as the foundation for multi-port line cards in both carrier-class DLCs and DSL Access Multiplexers (DSLAMs). In addition to AFC, several other major manufacturers of telecommunications equipment have standardized on Centillium's CopperLite CO chipset. The CopperLite CO chipset is highly integrated and offers maximum port density, supporting up to eight DSL ports with just two chips. Very low power requirements help keep power dissipation to just 0.65 watts per port. The CopperLite CO chipset is based on Centillium's software-upgradable Communications DSP, which ensures long product life cycles without the need for costly hardware upgrades. The chipset provides end users with high-bandwidth Internet access at speeds of 1536kbps downstream and 512kbps upstream over "Plain Old Telephone Service'' (POTS) regular copper phone lines. That is up to 27 times faster than conventional 56kbps analog modems.
