LANTIME M300/MGR: NTP Time Server with integrated mobile GPS radio
clock
The Meinberg LANTIME M300/MGR Time Server uses a fully integrated mobile GPS reference clock as its
time source. A highly stable internal oscillator accurately bridges periods of interference or temporary loss of
reception.
The M300/MGR includes the Meinberg MGR170 timing receiver and is intended for use in mobile
applications onboard vehicles, ships, trains, or airplanes. The MGR170 GPS receiver supports different
dynamic platform models to optimize the navigation engine for the specific mobile environment and allows
more precise data averaging and a more accurate position solution.
The variety of possible output configurations makes this time server the premier choice for a broad range of
mobile time and frequency synchronization applications.

Description
The GNU/Linux operating system of the LANTIME has been optimized to ensure a high level of security and reliability.
A large LC 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 for accessing 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.
Security Features
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.
SNMP Interface
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.
IPv6 Support
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.
High precision Oscillators available
The LANTIME M300/MGR is equipped with a high precision oscillator "TCXO" (look at oscillator options for details) as
standard. The oscillator determines the holdover characteristics (e.g. when the GPS signal is disturbed or jammed). For
applications with higher accuracy requirements there are several oscillator options available.
Modular system architecture
Because of its modular system architecture it is possible to order a LANTIME M300/MGR time server with several
additional frequency-, serial string- and pulse outputs.
