Calient Networks and EdenTree Technologies Announce Reseller Agreement; EdenTree Will Sell Calient's Automated Fiber Management Solutions Integrated With EdenTree's Lab Management Software.

SAN JOSE, Calif. -- Calient Networks, a leading carrier-class all-optical switching systems and software provider, today announced that it has signed a Reseller Agreement for the North American market with EdenTree Technologies, a leader in lab management and test automation solutions for network equipment manufacturers and service providers. EdenTree will sell Calient's DiamondWave(R) Automated Fiber Management (AFM) product into the rapidly growing test lab automation market.

EdenTree's customers are experiencing operational and capital cost constraints as they develop and deploy new IP-centric network equipment. Together, Calient and EdenTree bring dramatic productivity improvement to interoperability, product test, verification, and customer support labs. Rather than spending hours or days to set up and configure tests, lab personnel are able to instantly create test configurations with a few clicks of a mouse, allowing them to spend their time on value-added activities. Deployments to date have proved that when the combination of Calient's AFM managed by the EdenTree Lab Manager software is introduced into a lab, equipment can be more efficiently used, testing simplified, and even the largest of configurations provisioned in minutes. Test throughput is dramatically improved while costs are reduced.

EdenTree will now sell Calient's DiamondWave(R) Automated Fiber Management product to North American labs operated by equipment manufacturers, service providers, and enterprises, along with their award-winning lab management software.

Jay Oyakawa, CEO & President of EdenTree stated, "Calient's all-optical switching technology is the most cost effective all-optical switch on the market. It has a proven record in commercial networks worldwide. This gives us a high quality base on which to supply a software-controlled lab automation infrastructure designed for today's dynamic and demanding network lab environments. Calient's AFM allows us to offer our customers a scalable solution for automating optical connections in labs of any size."

"As fiber management in optical labs becomes increasingly complex and bandwidth increases to 1 Gbit/s and beyond, the partnership between Calient and EdenTree is a natural for lab applications," said Charles Corbalis, President & CEO of Calient. "EdenTree's user-friendly graphical user interface, combined with Calient's optical switching efficiency, makes lab automation beneficial and easy to implement. EdenTree Lab Manager Software is recognized for its ease of use and for the productivity improvements it delivers in labs and test beds." Managing reconfigurations of the physical connections between equipment in networks and labs, the system allows users to design and apply configurations remotely; to recall, share, and schedule those configurations; and to track the usage of lab resources, all from an intuitive graphical user interface or popular scripting languages.
