Our Network Time Servers

We make Stratum 1 Network Time Servers that use either GPS or CDMA as a time synchronization source. Our engineers have been designing precision GPS-synchronized Time Servers since the mid-1990s. And, we are the ONLY company with a Time Server that uses CDMA cell phone signals. Instead of mounting your GPS antenna on the roof of your building you can mount your CDMA antenna wherever you receive a cell phone signal - even inside windowless data centers.

Risk-Free Guarantee

Network Security Hardened. Extra care has been taken with our network time servers to "harden" them against network attacks. There are only a small number of settings that need to be made in a time server and they typically need to be set only once. Since this is a set-it-and-forget-it box we have eliminated all extraneous protocols/services in order to minimize exposure to security holes. You can also disable risky protocols such as Telnet.

Reliable Performance. The best reliability of any rackmount time server on the market with a demonstrated MTBF of over 25 years (225,000 hours). So reliable, you don't need a costly extended warranty or maintenance contract. All our time servers are provided with a 60-Day Guarantee, a 3-Year Warranty and free technical support for life.

Easy Installation. Installation is easy with an indoor antenna (CDMA or GPS). Our CDMA Time Servers are unsurpassed in ease of installation and we also offer a window-mount antenna kit for use with the GPS Time Servers. The user interface is easy-to-use and you can quickly bring the Time Server online with a few keystrokes or DHCP.

Fast Throughput. With fast NTP packet throughput you don't have to worry about your time server getting bogged down. Our network time servers can handle 200,000 clients while maintaining a timestamp accuracy of <10 microseconds.
