scope:

This second edition European Telecommunication Standard (ETS) is applicable to two-way (transmit and receive) as well as transmit only Very Small Aperture Terminals (VSATs) operating in the framework of a satellite network for digital communications purposes. 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 a VSAT.

ETS 300 160 [2] specifies the control and monitoring functions of VSATs, as defined in ETS 300 159 [1] and ETS 300 332 [3]. These CCMF are applicable to VSAT networks operating in any configuration including star, mesh and point-to-point connections.

This ETS specifies the CCMF.

NOTE: The use of the term "centralized" does not imply any particular topology VSAT system. It refers to the fact that functions are implemented at system level.

The CCMF which are the subject of this ETS constitute the set of functional entities that, at system level, monitor and control the correct operation of all VSATs in a network.

The VSATs of such networks 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.
