Meinberg

High-Performance NTP Time Server in a Compact Chassis

main product photo

The LANTIME M250 network time server is designed by Meinberg to offer superior NTP server performance in a medium or small-sized network environment. Constructed to order with a selection of signal receivers to enable you to synchronise your time server to the remote timing signal that you trust most. The LANTIME M250 can be built to support timing signals from any of the main satellite navigation systems in operation (GPS, Galileo, BeiDou, GLONASS) or from a long-wave timing signal radio service (e.g MSF or DCF77).

LANTIME OS

Meinberg's custom Linux-based LANTIME OS, a slim and secure operating system developed especially for the needs of a time server, powers the LANTIME M250 under the hood, providing access to all the security, network, and monitoring features that you could ever need from an enterprise-grade synchronisation appliance.

LANTIME Configuration and Monitoring

The powerful Web UI enables you to quickly and easily configure and monitor your LANTIME device, while the CLI provides power users with unparalleled flexibility and efficiency. The comprehensive LANTIME OS REST API provides a complete toolset for your network orchestration and automation needs, and SNMP support allows you to integrate your Meinberg systems into your existing network management system.

Oscillator Option

The LANTIME M250 is shipped as standard with a “TCXO” (temperature-controlled crystal oscillator), which provides excellent holdover performance if your server loses synchronisation with its upstream reference for any reason. The LANTIME M250 may also be shipped on request with a more powerful holdover solution (OCXO LQ/SQ/MQ/HQ). Please speak with a member of APC's specialist time synchronisation team for further information.
