LANTIME M320
NTP Time Server in a 1U Case for Server Rackmounting
The Meinberg LANTIME M320 time server is used to provide highly accurate time to networks of all sizes. They synchronise all systems that are either NTP or SNTP compatible. As a reference time source, this NTP system typically uses a built-in Meinberg reference clock or a compatible external time source (operating in stratum 1 mode). Up to 7 external NTP servers can also be set as time reference (operation as stratum 2 server).
A large display shows the state of the NTP subsystem.
Because of its modular system architecture, it is possible to equip this LANTIME time server with up to six ethernet ports, even fiber optic network ports and one or three Gigabit Ethernet ports are available as an option.
Oscillator Option
The LANTIME M320is 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 M320 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.
MRS – Multi Reference Source capable
In addition, this NTP time server can also be synchronised via other signal sources such as GNSS or NTP. PPS, 10 MHz, IRIG Time Codes are also available for our M320/MRS model.
The MRS version 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 utilising one or more remote NTP time servers. Thus, a LANTIME MRS time server can be run in a fully independent mode in environments where no source of time is available.
Configuration and Monitoring
The configuration of the system can be managed by using a standard web browser for accessing the extensive but straightforward HTML web 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.
