TrueTime To Supply Network Timing to GPRS Networks; Precision Time Servers to Provide Accurate Timing and Synchronization for GPRS Core Networks.

Business Editors/High Tech & Aerospace Writers

SANTA ROSA, Calif.--(BUSINESS WIRE)--March 6, 2001

TrueTime, Inc. (NASDAQ: TRUE), a leading provider of precision time and frequency products, today announced that its powerful NTS-200 Time Servers have been selected to provide precise timing and synchronization to Ericsson's GPRS core networks which are being deployed worldwide. GPRS is the first step towards the evolution to 3G.

GPRS enhances existing GSM and TDMA networks by introducing data packet transmission, enabling "always on" connectivity to the mobile Internet. With GPRS, users can enjoy high-speed delivery of e-mails with large file attachments, web surfing and access to corporate LANs. GPRS is based on packet switched technology and allows service providers the opportunity to charge for the amount of data sent or received rather than connection time. TrueTime's time servers will provide GPRS operators with accurate time stamps of when users send or receive information.

"Being selected by Ericsson is a true testament to the need for very precise timing and synchronization for these sophisticated high-speed communication networks. Our dedication to building the best timing solutions for today's complex networks is evident in our product performance as well as our customer support - two critical factors that we met in Ericsson's qualification process," said Lisa Withers, TrueTime's president and CEO. "The mobile Internet is the next wave in bringing content to people and we're very excited to be a part of this evolutionary technology."

About the NTS-200

The NTS-200 derives accurate time directly from the atomic clocks aboard the Global Positioning System (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 time server. 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.

Why Time and Synchronization is Vital for Today's Growing Networks:

Precise time and synchronization is vital for voice, data, video and e-commerce applications. Converged voice and video applications have timing requirements that demand an ever-increasing reliability and accuracy not realized with conventional computer clock systems. E-commerce applications including electronic fund transfers, stock trading, legal filings, medical record annotations, billing systems and other applications are dependent on accurate time - usually traceable to Universal Time Coordinated, UTC. In addition, the network infrastructure relies on many time dependent processes: fault diagnostics, network security algorithms, file ordering, database integrity, and others.
