Teradyne to Present Celerity Field Data At DSL World Forum; Automated Test System Streamlines Provisioning Process and Identifies 13% More ADSL Customers.

Business/Technology Editors

DEERFIELD, Ill.--(BUSINESS WIRE)--Oct. 15, 2001

Teradyne, Inc. (NYSE: TER) Broadband Test Division announced today that Chris Barton, Product Manager, will speak at a panel entitled Flow-Through Provisioning Challenges at the DSL World Forum being held in London, October 29-31, 2001. Mr. Barton will present field data showing how automated testing of copper loops via the current switch test bus can dramatically improve the DSL provisioning process and identify new lines that were previously disqualified. Test result information can be used to augment length-based records systems. Mr. Barton will show, based on actual results from an extended trial with a major European telco, how this approach was able to identify more customers whose lines were ready to support ADSL services, reduce the occurrence of false greens (lines that were qualified but were not DSL-ready), and reduce manual engineering.

The approach discussed is based on a new product introduced by Teradyne called Celerity. The system represents a breakthrough in testing technology as it uses patented measurement and analysis techniques to determine the insertion loss of a copper pair. The system tests in-service DSL lines, identifying the presence and dispatch location of data affecting faults. LECs can also perform a real time test to gather detailed loop qualification information. Line record systems are augmented to enable accurate pre-qualification of copper loops for DSL services by:

- Testing all lines exposed to DSL by directory number via the narrowband test
bus in existing switches (no external matrix is required).

- Determining the presence of speed impairments including load coils and
bridged taps.

- Determining accurate insertion loss using narrowband testing techniques as
the basis for qualification rather than length. Celerity has been proven
accurate in various switch technologies including the 5ESS via "no test trunk"
access.

- Refreshing information in the line record database weekly or monthly.

- Operating independently of other systems without requiring complex
interfaces.

The system accurately qualifies millions of lines in hours enabling Local Exchange Carriers (LEC) to test every line exposed to DSL every month. In addition, LECs can deploy more DSL sooner by increasing the pool of available DSL-ready lines and increasing the productivity of the provisioning process.

"Celerity is currently testing over 20 million subscriber lines in Europe and North America," says Barton. "The system gives service providers the information they need to market and deploy DSL services. By clearly knowing which lines in the network can support which data rates, service providers can tailor their marketing and support efforts to maximize their business opportunities."

"Celerity is a highly flexible solution with a feature set of modules that can be selected and deployed based on specific service provider needs," says Chris Bohrson, director of sales and marketing of Teradyne's Broadband Test Division. "The ability for a service provider to create a network testing system catered to his particular needs is crucial in today's market. Celerity operates independently of other systems and does not require a complicated interface to be implemented. In addition, LECs can deploy the system as an overlay where existing voice loop test systems are in place."

The presentation will be held at 3:15pm on Tuesday October 30 at the DSL World Forum in London.
