TrueTime To Supply Network Timing and Synchronization to NetWorld+Interop 2001 Las Vegas InteropNet Labs (iLabs)

SANTA ROSA, Calif. - May 3, 2001 - a leading provider of network time and frequency products, today announced that its innovative NTS-200 Network Time Server will provide precise time and synchronization services to the NetWorld+Interop 2001 Las Vegas InteropNet Labs (iLabs). The iLabs is NetWorld +Interop's live test-bed for the latest networking technologies and will demonstrate and put into practice key elements of the "next generation" Internet. The iLabs features the latest solutions to real engineering challenges in a live, vendor-neutral, open-standards arena. TrueTime's NTS-200 Network Time Server with its 12-channel GPS receiver will synchronize approximately 300 different networked devices in the iLabs. NetWorld+Interop 2001 Las Vegas, the definitive networking, Internet and telecommunications event, takes place May 6-11, 2001 at the Las Vegas Convention Center.

"We're very pleased to provide accurate timing and synchronization to iLabs' networks, workstations and other critical networked devices. Accurate time and synchronization is vital to today's networks and even more important as corporate networks and the Internet continue to grow and evolve," stated Paul Skoog, TrueTime's product marketing manager, network server appliances.
TrueTime's NTS-200 Network Time Server represents a breakthrough in network synchronization technology by combining a high-speed/high-capacity network interface, high-channel-count GPS receiver, web-enabled user interfaces, and a wide range of network protocol support for seamless integration into an existing network.

The high-bandwidth capability of the NTS-200 is important as modern broadband networks grow larger and faster and the need for reliable time becomes more critical. Previously, multiple timeservers were often required to adequately synchronize even a few hundred-network clients. Now, the high availability and throughput of the NTS-200 ensures that it can support thousands of network clients with no degradation in timing accuracy.

The NTS-200 derives accurate time directly from the atomic clocks aboard the GPS satellite system. By using an integrated, 12-channel GPS receiver, every visible satellite can be tracked and used to maintain accurate and reliable time. Using the Network Time Protocol (NTP), servers and workstations on the network automatically synchronize their clocks to the NTS-200. This synchronization process is repeated frequently as computer clocks are notorious for drifting away from the correct time.

Ease of use and remote access are key attributes of the NTS-200 state-of-the-art user interface. Designed with the network administrator in mind, the NTS-200's built in web pages offer current status information and full control of the server. Protocols such as SNMP and FTP are supported for automated monitoring of the server and convenient remote system upgrades. The rack-mounted unit is easily installed and quickly brought online with a few front panel keystrokes. An auto-detect 100BaseT/10BaseT interface easily integrates with existing Ethernet network equipment.

During NetWorld+Interop 2001 Las Vegas in booth #1975, TrueTime will have on display its complete line of innovative Time Servers including the NTS-200. In addition, TrueTime will debut its new NTS-150 Time Server.
