Market Wire, June, 2008

Turin Networks, Inc., a leading global provider of innovative Wireless Backhaul , Carrier Ethernet and Converged Services solutions for wireline and wireless network operators, today announced that the 10 Gigabit Ethernet switching and transport modules for the company's flagship Traverse® Multiservice Transport Switch have attained essential Carrier Ethernet certifications from the Metro Ethernet Forum (MEF). By successfully achieving MEF 9 and MEF 14 certification for all three service types defined by the MEF, Turin's Traverse is the industry's only platform to support the full array of certified MEF-compliant Carrier Ethernet services with scalability from 1 Mbps to 10 Gigabit Ethernet, in addition to traditional SONET, SDH and PDH transport and switching with scalability from DS1/E1 up to 10Gbps OC-192/STM-64.

"Our service provider customers made it clear that MEF Carrier Ethernet certification was an essential requirement for them," noted Bruce Miller, CTO and VP of Engineering for Turin Networks. "The scalability and versatility that we've built into our Traverse platform enabled us to meet this requirement, and to further enhance our iConnect(TM) for Carrier Ethernet solutions to facilitate the transition from circuit-based to a more packet-optimized infrastructure."

MEF certification is critical as service providers seek to create networks that provide their subscribers with ubiquitous and highly reliable Carrier Ethernet services worldwide. Turin's Traverse platform was tested by Iometrix in accordance with the MEF's "Test Plan for Ethernet Services at the UNI." The Traverse 10 Gigabit Ethernet Switching and Transport Modules received full MEF 9 Service certification for conformance with all three service types defined by the MEF: Ethernet Private Line (E-Line), Ethernet Virtual Private Line (EVPL) and Ethernet LAN (E-LAN), as well as MEF 14 Traffic Management conformance, which is critical for delivering differentiable service offerings with unique service level agreements.
