Satel SATELLINE-3AS Epic NMS exhibits a high power (10 W) transmitter and two receivers operated in a Diversity Reception mode. The Diversity Reception improves the reliability of the connection where there is a lot of signal fading caused by reflections. The high output power and the Diversity Reception make it possible to more than double the connection distances in comparison to ordinary SATELLINE-3AS NMS radio modems with 1 W output power.

The remotely manageable SATELLINE-3AS Epic NMS offers
configuration through radio, efficient diagnostics tools and accumulation of
operation statistics data, in addition to ordinary communication functions. The
management and surveillance of a network of 3AS Epic NMS radio modems is
effected through the Master Station connected by a serial interface to a PC with
dedicated Network Management software.
The 3AS Epic NMS radio modems monitor, on a continuous basis, the condition of
the radio connection, in particular the strength of the signal (RSSI) and the
voltage level of the power source as well as the inside temperature of the
modem. The information is transmitted to the SATEL NMS PC, where it is stored
and displayed as logs and trend data.
A SATELLINE-3AS Epic NMS network consists of remotely adjustable radio modems
operated in a polling mode, and controlled through the Master Station by
dedicated SATEL NMS software. The SATEL NMS software provides the user with a
powerful graphical tool for designing a radio network, which ensures that each
NMS radio modem receives and transfers only the messages intended for it, and
that each message is appropriately routed, using repeaters where necessary.
The user data and NMS information are transferred seamlessly together. The
Network Management System is compatible with most user protocols, making the NMS
network suitable for a wide range of applications.
