4 The Modular System LANTIME
The basic-system M1000-S is a set of equipment, composed of a reference clock (e.g.: GNSS satellite controlled
clock, long wave radio clock or IRIG/AFNOR time code reader), a single-board computer SBC LX800 500 MHz
with integrated network card and a power supply unit, all installed in a metal desktop case and ready to operate.
The implemented NTPD distributes the reference time from the used receiver cyclic in the network. Infor-
mation on the NTPD can be monitored via the network.
The installation of a LANTIME Server is very easy for the system/network administrator. The network ad-
dress, the netmask and the default gateway have to be configured (see chapter "Sarting of Operation"). The
network address or the equivalent name of LANTIME has to be shown to all NTP clients in the TCP/IP network.
As well as NTP the Linux system also supports a number of further network protocols: HTTP(S), FTP, SSH and
Telnet. Because of this remote configuration or status requests can come from any WEB browser. This access
via the network can be deactivated. Changes in the receiver status, errors or other important events are logged
either on the local Linux system or on an external SYSLOG-Server. In addition messages can be sent to a data
center via SNMP traps or automatically generated e-mails where they can be recorded. Furthermore all alarm
messages can be displayed by a large display which is accessed via network connection (e.g. VP100/20/NET).
In order to avoid a service interruption several LANTIME NTP servers can be installed in the same network to
obtain redundancy.
