3 Global Information LANTIME M400/GPS
The
LANTIME
(Local Area Network Time Server) provides a high precision time base to a TCP/IP network
(Stratum-1-Server). The NTP (Network Time Protocol) is used to synchronize all NTP clients with the refer-
ence. The several LANTIME variants differ from each other by the time reference and output configuration. A
GPS or GNSS (GPS, GLONASS, Galileo, BeiDou) receiver, GNS-UC (only GPS and Galileo) , a long wave
receiver (like DCF77, MSF or WWVB) or an IRIG time code receiver can be integrated as an internal reference
as well as a combination of these references (hybrid system). External references are also possible.
The LANTIME system is a set of equipment composed of an integrated GPS receiver, a single-board com-
puter and a power supply, all installed in a metal 19 inch modular chassis and ready to operate. A simplified
LINUX operating system is installed on the single-board computers flash disk. Eight push buttons and a display
can be used to configure and monitor the time server.
After the network connection has been established the time server can also be configured and monitored
remotely from a workstation via TELNET or FTP. An integrated web server enables access to the LANTIME by
using an ordinary web browser.
