That system clearly is a rudimentary (simply based on amplitude) failover controller---e.g., a shoestring setup could have an EOL cesium standard (relatively-accurate but -unreliable) that's not on UPS and a UPS-backed OCXO (like this unit) (relatively-inaccurate but -reliable) connected to ``REF IN'' and ``STBY IN'', resp. Honestly this standard appears to be ancient and the high-level build quality appears to be questionable.
