Product Description

The M900 can be configured with a wide variety of reference clock options, oscillator options (including rubidium), output options and power supply options. Complex systems can easily be configured with redundant receivers, redundant power supplies and multiple output signals.

The M900 can be equipped with up to 8 independent IEEE 1588 ports to synchronize large groups of PTP clients. The modular design offers very good scalability. If your PTP client population grows, you can simply add another PTP module.

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 following 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.
