Acterna and Teradyne Collaborate to Solve Broadband Deployment Issues.

VENICE, Italy -- Acterna, the largest provider of test and network management solutions to telecommunications network operators, and Teradyne (NYSE:TER), a leader in broadband service assurance solutions, today announced they are working together to provide broadband test solutions for the world's leading telephone companies. The parties have recently shared product information with the goal of developing an integrated product offering to customers. The shared technical specifications relate to Acterna's patented technology in its DSL Test Head (QT-200) and scalable architecture of its Quality Test Management System (QMS Test OS & EMS) and Teradyne's industry leading Loop Diagnostic Unit (LDU 100(TM)). Prototypes will be shown at the upcoming Broadband World Forum Europe 2004, trade show in Venice, Italy (September 20th - 23rd) at both companies' booths.

The Acterna DSL Test Solution covers the end-to-end delivery chain and segments faults from the customer premise equipment into the DSL network (DSLAM, ATM backbone, BAS, Radius Servers) and up to the ISPs. The Acterna QT-200 enables more efficient customer call management and operations and maintenance for network operators. The LDU 100 is Teradyne's core DSP measurement head for the Celerity(R) and 4TEL(TM )test systems and provides a common platform to support voice and DSL. The LDU 100 has been successfully deployed across Teradyne's installed base of some 140 million lines in support of voice and DSL copper loop testing.

"We are working with Teradyne to provide comprehensive DSL service assurance solutions to maximize performance, flexibility and cost-effectiveness," said Helmut Berg, president of Acterna's Telecommunications Division. "The objective of this collaboration is to provide solutions that enable service providers to beat the competition by quickly delivering the advanced new services of the coveted service 'triple play' more cost-effectively in an intensely competitive market."

"The goal of this collaboration is to enable our customers to leverage their extensive installed base of test heads by cost effectively migrating to end-to-end broadband service assurance solutions from Teradyne and Acterna. This is a good example of the commitment by both companies to provide DSL test solutions," according to Bob Copithorne, vice president and general manager of Teradyne's Broadband Test Division.
