NTPSync II™
Model 383 |
| |
The NTPSync II is a
Stratum-1 standalone network time server which provides a
high-accuracy time reference to IP networks via the Network
Time Protocol (NTP). The NTPSync II synchronizes systems that are either NTP or SNTP
compatible and uses a built-in GPS receiver as its reference
time source. The NTPSync II can also be utilized as a precision
1PPS / 10MHz time and frequency reference.
The NTPSync II is composed of a 6-channel GPS C/A-code
receiver, a single-board computer, a high performance oscillator and power supply.
The highly stable and precise
oscillator allows the NTPSync II to continue to provide
accurate time and frequency by bridging a temporary loss of
GPS reception. In
addition to NTP, the NTPSync II supports other network
services like SSH, HTTP(S) and SNMP traps. The system supports both IPv4 and IPv6
network protocols.
Configuration of the NTPSync II
is accomplished via menus on the backlit LCD display and
keypad in the front panel, or remotely using a web browser
or Telnet. RS-232 ports on the front and rear panels provide
additional monitoring and configuration options. Front panel
USB connector allows for easy software updates and
configuration upload / download. Alarms are
available via automatic emails, Windows Pop-up messages,
SNMP traps and an Alarm relay output connector in the rear
panel. |
