scope:

This second edition European Telecommunication Standard (ETS) is applicable to two-way (transmit and receive) as well as transmit-only Very Small Aperture Terminal (VSAT) satellite earth stations operating in the framework of a satellite network for digital communication purposes as defined in ETS 300 159 [1] and ETS 300 332 [3]. In these networks there is a set of control and monitoring functions at each VSAT and a separate set of Centralized Control and Monitoring Functions (CCMF). The control and monitoring functions are designed to limit interferences to users of the frequency spectrum due to a fault condition at the VSAT. This ETS is applicable to VSATs operating in any network configuration including star, mesh and point-to-point connections.

This ETS specifies the control and monitoring functions of a VSAT. ETS 300 161 [2] specifies the CCMF.

The VSATs which are the subject of this ETS, are designed for unattended operation and with transmission capability limited to baseband digital signals. Transmission and reception at a VSAT relate to transmission and reception over the satellite.

CCMF constitute a set of functional entities that, at system level, monitor and control the correct operation of all VSATs in a network.

 This ETS does not include any specification or information about the installation of the VSAT.
