Sonoma N12(GPS)

The Sonoma is a Stratum 1 Time Server that provides an accurate and reliable source of network time inside your firewall.It can serve accurate time to any system running an NTP or SNTP client. With dual gigabit ports and a fast microprocessor for high-capacity packet throughput (7,500 requests/second), the Sonoma can support hundreds of thousands of network clients with an NTP timestamp accuracy of <10 microseconds. The highly-integrated solid-state design is very reliable design is very reliable, and you can easily manage it via one of the network ports or the RS-232 serial port. A Web Interface (HTTPS) is also provided for status monitoring using your internet browser.


Network Security Hardened

Extra care has been taken to "harden" the Sonoma against network attacks. There are only a handful of settings that you need to make and they are typically set only once in the lifetime of the product. Since this is a set-it-and-forget-it box, we have eliminated all extraneous protocols/services in order to minimise exposure to security holes. You can change critical settings via SSH or Telnet and monitor the alarm/status information by using HTTPS, SNMP, SSH or Telnet. Security-conscious users can disable any or all of the risky protocols such as HTTPS, Telnet, Time and Daytime or restrict access to specific hosts.


Best Holdover Performance

The Sonoma will continue to serve Stratum 1 time for a substantial period if the GPS reference signal is ever lost. This is called the holdover period and it is dependent upon the quality of the oscillator and the software control algorithms. The basic Sonoma is provided with a TCXO (drift is 10 milliseconds/day), and it will continue to serve accurate Stratum 1 time for a full 24 hours after signal loss. This is the best holdover performance for any time server on the market with a TCXO. For even better holdover performance you may want to consider and oscillator upgrade.


PTP/IEEE-1588 Grandmaster Clock Option

The Sonoma can be configured as an IEEE-1588-2008 compliant, Precision Time Protocol (PTP) Grandmaster Clock with high capacity and hardware in real-time with daily and weekly charts. The PTP/IEEE-1588 option can be added to one or both of the gigabit ports and delivers the level of performance that is required in high-speed, low-latency systems.


Measurement Statistics and Charting

Real-time charting on NTP, Oscillator and CPU statistics is available via the Web Interface. Measurements are continuously computed and displayed in real-time with daily and weekly charts. The oscillator statistics are good for verification that the unit was locked at a certain time. NTP statistics show the NTP packet rate and the accuracy of the NTP and System Time relative to UTC. The CPU statistics show the free memory, processor load and operating temperature.


High Reliability and Free Technical Support for Life

The Sonoma uses EndRun's power efficient, fanless design that achieves an estimated MTBF of over 25 years (16 years with Rubidium). The system is made in America, backed by a 3-year warranty, and provided with free technical support via phone or email for life.
