3 IMS-M500 System Description
3.1 Device Design, Functions and Area of Application
The IMS-LANTIME-System is a set of equipment composed of a reference module, a single-board computer
module (LAN-CPU) with integrated network card, and a power supply unit, all installed in a modular chassis
and ready to operate. The input/output signals of the IMS systems are provided on the connection side via I/O
modules.
The implemented NTPD distributes the reference time from the reference module cyclic in the network. Infor-
mation on the NTPD is monitored on the LC-Display (if available) or can be queried via the network.
The installation of an IMS LANTIME is very easy for the system/network administrator. The network ad-
dress, 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.
