LANTIME M600/GPS: High End NTP Time Server with integrated GPS radio
clock
[1]The Meinberg LANTIME time server is used around the world to provide accurate time to networks of any
size. It synchronizes all systems either NTP- or SNTP-compatible and uses a built-in Meinberg GPS radio
clock as its reference time source. A highly stable and precise oscillator is capable of bridging interferences
or a temporary loss of reception. The standard M600 model already offers a broad range of interfaces and
can be customized to meet the special requirements of your application.

Description
The GNU/Linux operating system of the LANTIMEs SBC (Single Board Computer) has been optimized to ensure a high
level of security and reliability.
A large VF display shows the state of the internal GPS receiver and the NTP subsystem. Three LEDs (green/red)
indicate the status of the three main components: Reference Time (GPS), Time Synchronization Service (NTP) and
Network (Link status). A fourth red LED is labelled ALARM and can be configured to signal any event that is covered by
the notification handling routines.
The configuration of the system can be done by using a standard web browser to access the extensive but
straightforward html interface. Alternatively a text based and menu driven setup utility can be started from the shell
prompt after logging into the unit via Telnet or SSH.
The security-related features of LANTIME time servers satisfy highest demands. The time synchronization data can be
reliably signed and secured by symmetric keys (MD5) and the NTP autokey procedures. This protects the clients
against manipulated time and man-in-the-middle attacks and allows them to verify that the NTP packets they received
were send by the LANTIME. Additionally the whole LANTIME configuration can be done by using encrypted channels
(e.g. SSH, HTTPS or SNMPv3). Every unused/unneeded protocol can be disabled in order to reduce possible points of
attack.
In order to support network management systems the LANTIME time servers offer an extensive SNMP interface, which
can be accessed by SNMP V1, V2.c and V3. It allows the monitoring of all relevant system parameters (including
operating system parameters, network interface statistics, detailed GPS and NTP status information as well as the
complete system configuration) and can be used to alter the LANTIME configuration via SNMP set commands, too.
LANTIME time servers are designed to be deployed in IPv6 networks, the NTP time synchronization as well as the
configuration interfaces (Web-based, SSH and SNMP) comes with IPv6 support. You can assign several IPv6
addresses and the system supports automatic configuration by IPv6 autoconf.
The LANTIME M600 GPS is equipped with high precision oscillator "OCXO LQ" (look at oscillator options for details) as
standard. The oscillator determines the holdover characteristics (e.g. when the GPS signal is disturbed or jammed).
Oscillator options like "OCXO MQ", "OCXO HQ", "OCXO DHQ". A Rubidium oscillator is available for our 3U modular
systems (LANTIME M900) to fulfill higher requirements.
