    LANTIME/SHS/BGT :: NTP Time Server with Integrated Highly Secure Hybrid Receiver Technology (GPS/DCF77) in 3U housing




Product Description

The LANTIME M900 offers a lot of space for output modules and several power supply options in its 3U rackmount chassis. This allows for a large number of different outputs like 1PPS, 10MHz, IRIG, serial timestrings or up to 7 Ethernet ports to support large network infrastructures. Meinberg will create an individual solution based on your specific requirements, please contact us.

As an alternative to GPS a number of other reference time sources are available for inclusion in the M900 system, for example DCF77 (PZF), IRIG (TCR), MSF or NTP (from an upstream server).

An LC-Display shows the status of the reference time source as well as the time service. Additionally three bi-color (green/red) LEDs clearly indicate the state of the three main components (time source, network time service, network) and a red alarm LED signals major system failures.

The configuration and control of the system can be carried out via a powerful yet easily understandable web user interface, a text-based console setup tool is available for easy access to most configuration options and status information when you logged in via SSH, Telnet or the serial front port.

The M900 platform can be combined with all available Meinberg oscillator options, ranging from the cost effective TCXO up to a Rubidium based oscillator with extremely stable holdover capabilities, ensuring a tighly synchronized network environment in the absence of any external reference, even if this situation lasts for days, weeks or even months.

Please note that the technical specifications for pulse, frequency and serial outputs are based on a sample configuration and can be modified in order to fulfill your individual requirements.
