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.

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 Options
The LANTIME M320 comes standard with a "TCXO" (Temperature Controlled Crystal Oscillator) which provides excellent holdover performance in case your time server loses synchronization with its upstream reference for some reason. On request the LANTIME M320 can also be delivered with a more powerful holdover solution (OCXO LQ/SQ/MQ/HQ/DHQ) (see oscillator overview).

MRS - Multi Reference Source capable
In addition, this NTP time server can also be synchronized via other signal sources 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 utilizing one or more remote NTP time servers. Thus, a LANTIME MRS time server can be run in 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.
