Spirent Communications And Samsung Electronics Announce Interoperability Alliance For Broadband DSL Networks

Berlin (OTS) - DSL WORLD FORUM - Spirent Communications, a wholly owned business unit of Spirent plc (NYSE: SPM and LSE: SPT), and Samsung Electronics Co., Ltd., a leading provider of broadband telecommunications equipment, today announced a joint interoperability alliance for their Digital Subscriber Line (DSL) solutions. The agreement is intended to help service providers simplify DSL infrastructure installation and maintenance, as well as speed their time to market for broadband services.

The agreement is aimed at achieving interoperability of key components in Spirent's CenterOp(tm) for DSL solution family -including its REACT(tm) remote test operations support system (OSS) and CopperMax testing probes - with Samsung's Ace-MAP(tm), a multi-service access platform integrating DSL access multiplexer (DSLAM), next-generation digital loop carrier (NGDLC), and Access Gateway functionality. Under this arrangement, Spirent's CopperMax/RT(tm) probes will allow service providers to test their broadband lines using the integrated test access provided by Samsung's Ace-MAP, as well as through Spirent's own access devices. The resulting solution not only offers a single approach for managing service quality across a provider's DSL network, but assures providers using products from either vendor of their capacity to seamlessly interact with each other.

"Spirent is dedicated to working with leading network equipment companies around the world to bring automated network monitoring and analysis to next generation service providers," said Jim Schleckser, president of Spirent Communications' Service Assurance division, which produces the REACT OSS and CopperMax probes. "Partnering with Samsung will also open opportunities for Spirent to assist service provider customers in burgeoning new broadband markets across Asia Pacific."

"Samsung's strong customer base in Korea - with the world's highest DSL penetration rate - and proven DSL access technology around the world has made Samsung the leader in these rapidly developing markets," stated Dr. Young Cheol Oh, VP of Network Systems . "We look forward to working with Spirent to expand our DSL leadership into North America."

Under the first phase of this alliance, interoperability is concentrated on Samsung's Ace-MAP, Spirent's CopperMax/RT, a low-profile, full-featured test probe, and REACT. In subsequent phases, the companies will confirm interoperability between the Ace-MAP, REACT, and Spirent's CopperMax/iCon(tm), designed to provide automated Internet Protocol (IP) validation on DSL installations. Spirent's REACT OSS is widely accepted in the global public switched telecommunications network, with more than 20,000 nodes already in service in a variety of incumbent and competitive local exchange carriers, interexchange carriers, and global providers.
