Meinberg LANTIME M300/MRS
NTP Time Server synchronized by GPS, 1PPS, 10MHz, IRIG or NTP.
Description
Meinberg LANTIME time server are used around the world to provide accurate time to networks of any size. The LANTIME M300/MRS is a very reliable and accurate time source for all systems either NTP- or SNTP-compatible and it uses a built-in ultra-stable oscillator as its primary reference time source.
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 Agorithm (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.
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 MRS version of the LANTIME M300 comes with a high quality OXCO and is designed to act as a reliable time source in applications where no antenna can be installed. The internal OCXO-HQ can be fully disciplined by utilizing one or more remote NTP time servers or the other input sources. In installations where no source of time is available, the LANTIME M300 MRS can be run in a fully independent mode which requires setting the time manually during initial configuration. Such a free running MRS (i.e. without any available external reference like GPS or NTP) develops a maximum time error of less than one second per year.
All outputs of the M300, including PPS, 10MHz and the Sysplex Timer output are fully functional and stable with all possible references (NTP, GPS, 1PPS, 10MHz, IRIG or free running).
The GNU/Linux operating system of the LANTIMEs SBC (Single Board Computer) has been optimized to ensure a high level of security and reliability.
The configuration of the system can be managed 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.
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.
