LANTIME M600/MRS
NTP Time Server synchronized by GPS/1PPS/10MHz/IRIG/NTP

Image Zoom
Meinberg LANTIME time servers are used around the world to provide accurate time to networks of any size. The LANTIME M600/MRS synchronizes all systems that are NTP- or SNTP-compatible and uses a built-in Meinberg GPS radio clock and supports a broad range of other reference time sources like 1PPS, 10MHz, IRIG time codes (both DCLS and AM) or upstream NTP servers. A highly stable and precise oscillator is capable of bridging interferences or a temporary loss of reception and can also be used as a stable independent time base when operated in free running mode.

Description
NTP Time Server synchronized by GPS/1PPS/10MHz/IRIG/NTP

As an ultra stable NTP time provider, the LANTIME M600/MRS not only represents a highly accurate source of synchronization for all network devices supporting the Network Time Protocol (NTP) or the Simple Network Time Protocol (SNTP), it also offers a number of legacy time and frequency outputs for keeping non-networked devices in sync.

The Meinberg MRS technology (Multi Reference Sources) enables you to utilize one or more time and frequency references in prioritized order defined by your individual requirements. The Intelligent Reference Switching Algorithm (IRSA) developed by Meinberg engineers ensures that switching from a highly accurate reference source (e.g. GPS) to a less accurate one (e.g. IRIG or NTP) is delayed as long as the internal ultra stable oscillator is capable of maintaining an accuracy level that is better than the one of the next available reference source in the priority list.

In lab environments the MRS technology offers a flexible solution to changing availability of different synchronization sources and for highly critical operative systems. The possibility to use multiple independent sync references allows you to fulfill redundancy requirements of your network synchronization solution.

Another field of applications for MRS technology is the monitoring and measurement of synchronization sources, e.g. determining and logging the accuracy of an IRIG generator or a PPS source.

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 display shows the state of the internal GPS receiver and the NTP subsystem.

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.

Because of its modular system architecture it is possible to equip a LANTIME time server with a number of different reference time sources. Optionally several additional frequency-, serial string- and pulse outputs are available and by combining two (even different) time sources and redundant power supplies, high-availability systems are no problem.

The LANTIME M600/MRS is equipped with high precision oscillator "OCXO HQ" (look at oscillator options for details) as standard. The oscillator determines the holdover characteristics (e.g. when the GPS signal is disturbed or jammed). The oscillator option "OCXO DHQ" is available to fulfill higher requirements.

Please note that the GPS antenna is not included in the standard scope of delivery and has to be ordered separately, if you are planning to use GPS as a synchronization source.
