The high-performance NTS-200 Network Time Server is used to synchronize clocks on servers and workstations across entire enterprise networks. Accurately synchronized clocks are critical for network log file accuracy, billing systems, e-commerce and B2B transactions, database integrity, software development, and many more essential applications in today's corporate enterprise. The NTS-200 represents a breakthrough in network synchronization technology by combining a high-speed/high-capacity network interface, high-channel-count GPS receiver, web-enabled user interface, 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 time servers were often required to adequately synchronize even a few hundred network clients. Now, the high availability and throughput of the NTS-200 ensures that typical time stamp accuracy of 1 to 10 milliseconds can be sustained while handling 100 NTP packet requests per second. This translates into the support of tens of thousands of network clients with no degradation in timing accuracy. Equally important is the ability of the NTS-200 to handle peak loading conditions when many NTP requests are received at the same time. If NTP packet traffic increases beyond the 100 requests per second range, time stamp accuracy between 10 and 100 milliseconds is maintained well beyond 200 requests per second with no disruption
of service.

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 via a standard browser interface. Many network protocols are supported including SNMP for automated monitoring of the time server and FTP for convenient remote system upgrades. The rack-mounted unit is easily installed and quickly brought online with a few front panel keystrokes. An autosensing 10/100Base-T Ethernet interface easily integrates with existing network equipment. A GPS antenna and cable is included.

The Stratum 1 level 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. Because the NTS-200 is synchronized to the GPS satellite system, precise network synchronization is available around the globe. NTS-200 units deployed across widely separated local networks maintain synchronization across an organization without requiring time transfer between them. If the GPS reference signal is lost, the NTS-200 can automatically revert to a client mode and retrieve time from other user designated network time servers. This prevents disruption of service to the network and the network administrator is notified immediately via SNMP of the change in time reference status.
