The Meinberg time servers are worldwide used to provide time accuracy on different types of network. The LANTIME synchronizes your devices on NTP or SNTP protocols. Different kind of source is possible: GPS, IRIG-B, DCF, NTP or PTP. An accurate oscillator is used as a bridge between the source of synchronization and timing problem in interference or temporary loss of source.

-Client Synchronization PTP, NTP ou SNTP
-Web based status and configuration interface (Demo) and console based graphical configuration utility
-Supported networking protocols: IPv4, IPv6, HTTPS, HTTP, SSH, TELNET, SCP, SFTP, FTP, SYSLOG, SNMP

-USB port for performing updates, lock front panel, and backup/restore configuration and log files.
-Antenna connected with up to 300m of standard coaxial cable RG58, 600m with RG213 and more with Fiber optic).
-Several RJ-45 ethernet interfaces 10/100 MBit

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 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.

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 M300 GPS is equipped with a high precision oscillator. The oscillator determines the holdover characteristics. For applications with higher accuracy requirements there are several oscillator options available.

**NTP/PTP time server** :
The lastest from MEINBERG in LANTIME poducts, the **M400**.

This new time server, compact and user-friendly like the others in the M serie, is able to generate (besides NTP and PTP function) a multitude of time frames and synchronisations as 10Mhz, PPS, IRIG, etc... This M400 time server can be synchronized by GPS, IRIG, NTP or all in the same time...

All MEINBERG's time servers can be configured to notify (by trap SNMP, email, relay, etc ...) users to a possible failure.
Supported network protocols are: NTP (v2/3/4), IPv4 et IPv6, DHCP, SSH, HTTPS, HTTP, FTP, STP, Telnet, SNMP.
LCD monitor on the front panel and a GUI are available to drive the equipment locally or remotely.

Because of its modularity and flexibility, a variety of extra features as network ports, programmable pulses, an AC or DC power, ... could be added in option, the M400 will fit your requirement!
