NTPSync XLS®
Model 383 |
|
| |
NTPSync XLS® is a stratum-1 standalone time
server which provides a high-accuracy reference time to IP
networks via the Network Time Protocol (NTP). NTPSync XLS is
assembled in a modular case which includes, GPS receiver, a
single board computer, and a power supply unit.
Configurable settings can be
modified via menus on the 2 row x 40-character LCD display
with back light and the four buttons in the front panel. The
single board computer runs a Linux Operating System which is
loaded from flash disk into RAM at power-up. In addition to
NTP, the Linux operating system supports other network
services like SSH, HTTP(S),
SNMP. The system supports IPv4 and IPv6 which allows remote
configuration or monitoring across the network, e.g. using a
common web browser.
Remote access from the network
can also be disabled for security reasons. Changes in the
GPS receiver status, error conditions, and other events
generated error messages
can be logged on either the local Linux system, or on
another syslog server in the network.
Additionally, those messages can be sent to a management
console by SNMP traps, automatic emails, by Windows
Popup-Messages or optional remote NTP displays. If it is
necessary to provide redundancy against hardware failure
then it’s also possible to install several NTPSync XLS
servers in the same network. |
