ANAHEIM, CALIFORNIA -- February 23, 1999 -- Teradyne, Inc. (NYSE:TER) has announcedthe introduction of the Spectrum™ 8950-Series ADSL Manufacturing Test Platform. The Spectrum Asymmetric Digital Subscriber Line test system integrates in-circuit, functional, and system-level tests within a single-stage manufacturing test platform for ADSL-based products serving the telecommunications industry. Announcement of the versatile ADSL manufacturing test platform was made at the electronics manufacturing trade show NEPCON West held here February 23-25, 1999.

Lucent Technologies Places First Order

Orders for the Spectrum 8950-Series have already been placed, including an order from Lucent Technologies. Lucent, the telecommunications and technology giant, plans to use the Spectrum 8951 to test ADSL line cards.

"Lucent bought the Teradyne ADSL test system because of our long-term working relationship, and we knew Teradyne would support the product,"said Sid Hardy, Engineering Manager, Lucent Technologies, Oklahoma City manufacturing facility.

The Spectrum 8950-Series ADSL Manufacturing Test Platform is a single-platform solution for in-circuit, functional, and system-level testing of ADSL modems, line cards, Digital Subscriber Line Access Multiplexer (DSLAM) products, Remote Access Server (RAS) products, and routers.

The VXI-based architecture provides superior test capabilities for ADSL equipment suppliers. Multiple test strategies may be implemented during the ADSL product life cycle including structural test, ADSL conformance test, ADSL performance test, and ADSL transmission testing. The Spectrum 8950-Series Manufacturing Platform delivers test capabilities for full rate ADSL, RADSL and G.LITE ADSL products, as defined in the ANSI T1.41-1998 Issue 2 release.

Testing for Tomorrow's ADSL Technology

As ADSL technology matures, the open architecture and modular design of the Spectrum 8950 provides ADSL test adaptability to grow with this developing technology--and the versatility needed to adjust to unforeseen directions the technology may evolve. Adaptability provides room for growth, and versatility allows test resources to be reconfigured and reused.

A unified Spectrum platform aids in test program migration, system re-configuration, and test strategy redeployment. The Spectrum 8950-Series is designed with industry standards to transition today's test to accommodate tomorrow's ADSL technology.

The Spectrum 8950-Series' open architecture reduces ATE acquisition costs with a modular design that can be easily configured to meet user test requirements without excess software or hardware overhead. The standards-based design consists of VXI plug&play and Window™ NT for easy expansion as test demands change. Spectrum systems can be reconfigured with industry-standard hardware, instrumentation, and software to minimize operating and upgrade expenses.

Standard, general-purpose Spectrum 8800-Series systems may be upgraded to include the ADSL test capabilities. Programs developed on the 8950-Series may be executed on comparably equipped Spectrum 8800-Series test systems, maximizing the available test capacity on installed systems.

Spectrum 8950-Series Availability

The Spectrum 8950-Series ADSL Manufacturing Test Platform will ship early spring 1999.
