"Gigabit to the Classroom" - fastest school network in the world!

Spokane, Washington, November 7, 2002 - Tylite, Inc., a Pacific Northwest company that aims to be the premier system integrator of high-speed Ethernet over Fiber networks, today announced they have completed the world's first implementation of a "Gigabit to the Classroom" network for Central Valley School District #356.

Central Valley awarded the project to Tylite to link two new high schools, one middle school and one elementary school to the school district administration building. The project included labor, materials, equipment, installation and maintenance of the Wide Area Network (WAN) for the school district.

"Our new district network is performing as designed by Tylite, delivering Gigabit bandwidth right to the classroom," said George Amend, Instructional Technology Supervisor. "Our teachers and students have ready access to video, data and video conferencing applications for instructional services."

Amend adds, "Tylite's network design is well-engineered, well-installed and well-supported - their project team has been diligent in ensuring the highest level of performance with all aspects of this installation."

Over 80 rooms in each new high school are connected via fiber to Gigabit Ethernet switches and to the WAN or Educational Metropolitan Area Network (EMAN). The network carries voice, video and data services, enabling teachers, students and faculty to instantaneously access learning and communication resources at 1000 Megabits per second (Mbps). Using Smart Bits network test equipment, Tylite measured network traffic speeds and load conditions to validate that the network met expectations as established by the contract.

Working closely with Foundry Networks, SMC Networks and RAD Data Communications, Tylite provided a next-generation fiber network infrastructure for Central Valley that not only supports their long-term education goals, but also minimizes annual operating costs associated with individual school servers and legacy phone services. RAD's "TDM over IP" technology is used to deliver phone service to the new schools over the Gigabit Ethernet infrastructure.

In addition to the integration services, Tylite provides user training and second tier service and maintenance.

"We were pleased to be chosen to implement this Gigabit network," said Jim Wilson, President and CEO of Tylite. "Central Valley now has the ability to provide instructional content to their students with a "best-in-class" network at a price point which was significantly lower than the other bidders."

Tylite is also continuing development of its unique Future Prooftm Fiber to the Home technology for cities that want to combine school networks with Fiber to the Home networks.
