Analog Devices Announces First T1-On-A-Chip Solution

ADI Builds on Leadership Position in VoIP Processor Market and Achieves 24 Ports on a Single Chip Analog Devices (NYSE: ADI), today announced a chip that enables a new level of communications capacity for networking and remote access equipment. The new ADSP-21mod980 contains 24 ports, the equivalent of a T1 communications line, achieving the highest level of density in the industry with a single integrated circuit. The new high- density Internet access solution enables the convergence of voice and data networks through a unique ability to configure any port for any protocol. Measuring approximately 1.9 square inches, the ADSP-21mod980 consumes the lowest power and space per port and is based on a field-proven architecture that is programmable and flexible. "Analog Devices' goal is to provide future-proof Internet access solutions that support the growing number of Internet subscribers, protocols and connection rates," said Robert Fine, Remote Access Server Product Line Manager. "The ADSP-21mod980 delivers a proven, flexible, and cost-effective approach to support the convergence of both voice and data on the same network." "As the network moves toward voice and data convergence, devices that support multi-service protocols are key to competitive access," said RHK analyst, Claude Romans, Director of Loop Access. "To ensure profitable and cost-efficient access, service providers need network access systems that support multiple protocols from a single-point access infrastructure. Multi- service access devices with high density, as well as low cost and power, will deliver the features required by service providers and corporations to build and expand their network access capabilities." The new network access solution, the ADSP-21mod980, offers industry- leading flexibility, density, power consumption and operational savings for Internet service providers (ISPs). The device enables ISPs to become both a data and Internet telephony service provider (ITSP), expanding access offerings while reducing total cost of operation through reductions in administration, facilities, equipment and WAN services. The ADSP-21mod980 features a universal software package for V.90, K56Flex, V.34, ISDN, Fax (FoIP) and Voice over IP (VoIP) protocols. Service providers are able to make significant cost savings by the flexibility and increased load handling capabilities of ADI's any-protocol-on-any-port device. Each of the 24 ports on the ADSP-21mod980 is able to independently process different standards. For example, the chip can handle a V.90 modem on one port, G.729A VoIP on another, and/or a fax call on a third. In addition, the software architecture enables real- time call statistics and diagnostics tools for improved quality of service levels. The VoIP software package also includes support for voice, fax and data call discrimination, fax over network, speech activity and host software interface. The ADSP21mod980 consumes only 60 mW per port, which, at 3.3 V, represents less than one third the amount of power than the closest competitor. The solution processes 600 million instruction per second (MIPS) and integrates 2 megbits of SRAM, in a 35 x 35 mm 352-lead BGA package. ADI's Internet Gateway Processor Solutions The ADSP-21mod980 is the company's third single-chip Internet Gateway Processor, or digital modem. Since the introduction of the ADSP-21mod870 in 1997, ADI has successfully doubled density every nine months and achieved the goal of providing industry- leading density and support for evolving Internet protocols and data types. ADI's family of Internet Gateway Processors are embedded 16-bit DSPs and software solutions that have enabled the development of new Internet access products including high- density remote access servers and remote access concentrators, in addition to modem test equipment, VoIP systems and multi-service gateways. The ADSP-21mod-Series has currently been adopted and deployed by a number of industry leaders, including Lucent InterNetworking Systems, Brooktrout, Ericsson, Mapletree Networks, Netaccess and Digi International. For additional information see ADI press releases dated March 17, and April 14, 1999 at Pricing & Availability The ADSP-21mod980 is packaged in a 352-lead PBGA (plastic ball grid array) measuring 35 mm x 35 mm and is priced at $265 each in quantities of 1,000 units. This price includes all required hardware and software. Prices may vary depending on software configurations. Samples of the ADSP-21mod980 are available today, with full production slated for the fourth quarter of 1999.
