ADC and Hekimian Team To Reduce HiCap Testing Costs.

Business Editors & Technology Writers

MINNEAPOLIS--(BUSINESS WIRE)--May 24, 2000

REACT 2001, Soneplex Remote Test Access Unit Integrated to Deliver

More Efficient, Effective Network Analysis and Diagnosis

ADC (Nasdaq: ADCT; www.adc.com) and Hekimian (www.hekimian.com) announced today that Hekimian's REACT 2001(TM) testing software now offers full interoperability with ADC's Soneplex(R) system. The innovation means carriers now have an alternative to traditional, costly methods for monitoring and testing remote network sites. The software is designed to provide closer, more convenient management of Soneplex delivered HiCap circuits at substantially reduced cost.

Release 2.310 of Hekimian's industry-standard REACT 2001 remote testing operations support system (OSS) now includes support for ADC's Soneplex Remote Test Access Unit (RTAU) which communicates with REACT through ADC's Shelf Controller Unit (SCU) for increased intelligent network management. This capability closes the gap between these two market-leading products, letting carriers use REACT 2001 to access HiCap T1s served from Soneplex and perform test sessions using ADCs Soneplex RTAU.

"Historically, many remote sites have not been adequately monitored and tested because carriers could not justify the high expense of a digital test access unit," said Sylvia Ketch, senior marketing manager for ADC's Broadband Access and Transport Group. "ADC's test access solution with the RTAU is designed to facilitate remote testing and monitoring at a lower cost than using traditional digital test access unit (DTAU) testing practices."

"We're pleased to team with ADC to extend REACT 2001's industry-leading, end-to-end service assurance capability to include Soneplex," said Dave Gellerman, vice president of technology and corporate development for Hekimian. "This latest achievement is yet more proof of our commitment to helping carriers harvest new value from the information and intelligence already present in their networks."

Graphic display of test results speeds diagnosis of network issues

Network operations personnel responsible for testing HiCap circuits can now use REACT 2001 to enter the circuit ID of any T1 HiCap fed from an RTAU-equipped Soneplex shelf and perform intrusive testing using REACT 2001's easy-to-use graphical user interface. This virtually eliminates training time for the tester, while offering the service provider assurance that 100% of its RTAU-equipped Soneplex shelves are accessible for immediate testing from the Network Operations Center Besides dramatically improving the economics of network testing, this graphical display is designed to allow network professionals more rapidly assimilate information about the status of an increasingly complex and geographically dispersed network infrastructure. Shortened time to diagnosis generally reduces latencies and failures, helping to resolve many service problems well before customers can become aware of them.
