The Modular System LANTIME

LANTIME is a set of equipment composed of a satellite controlled clock GPS167,
a single-board computer SBC GEODE 266 MHz with integrated network card, and a
power supply unit T60B, all installed in a metal desktop case and ready to operate.
The interfaces provided by LANTIME are accessible via connectors in the rear panel
of the case. Details of the components are described below.

The implemented NTPD distributes the reference time from the GPS receiver cyclic
in the network. Information on the NTPD is monitored on the LC display or can be
inquired via the network.
The installation of LANTIME is very easy for the system/network administrator. The
network address, the netmask and the default gateway have to be configured from the
front panel of LANTIME. 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 the large display VP100/20/NET that is accessed via network
connection. In order to avoid a service interruption several LANTIME NTP servers
can be installed in the same network to obtain redundancy.
