Foreword
This European Telecommunication Standard (ETS) has been produced by the Satellite Earth Stations
(SES) Technical Committee of the European Telecommunications Standards Institute (ETSI), and, has
undergone the ETSI standards approval procedure in Public Enquiry 20 and Vote 25.
Every ETS approved by ETSI is a voluntary standard. This ETS may contain text concerning type approval
of the equipment to which it relates. This text should be considered as guidance only and does not make
this ETS mandatory.

1 Scope
This European Telecommunication Standard (ETS) is applicable to two-way (transmit and receive) 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]. In these networks there is a set of
control and monitoring functions at each VSAT and a separate set of Centralised 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 defines the requirements for the control and monitoring functions in a VSAT and is only
applicable to the satellite access subsystem of the VSAT. ETS 300 161 [2] contains requirements for the
Centralised Control and Monitoring Functions (CCMF).
This ETS does not include any requirement, recommendation or information about the installation of the
VSAT.
2 Normative references
This ETS incorporates by dated or undated references, provisions from other publications. These
applicable references are cited at the appropriate places in the text and the publications are listed
hereafter. For dated references, subsequent amendments to, or revisions of any of these publications
apply to this ETS only when incorporated in it by amendment or revision. For undated references the latest
edition of the publication referred to applies.
[1] ETS 300 159: "Satellite Earth Stations (SES); Transmit/receive Very Small
Aperture Terminals (VSATs) used for data communications operating in the
Fixed Satellite Service (FSS) 11/12/14 GHz frequency bands".
[2] ETS 300 161: "Satellite Earth Stations (SES); Centralised control and monitoring
functions for VSAT networks".
3 Definitions
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 system.
Control channel(s): a channel or channels by which VSATs receive control information from the CCMF.

5 Requirements
5.1 General
This ETS specifies a minimum set of control and monitoring functions that shall be implemented on two
way VSATs in order to minimise the probability that they may originate transmissions that may interfere
with other systems.
A VSAT shall implement two sets of control and monitoring functions:
a) Monitoring function: this function encompasses all the checks and verifications that the VSAT shall
perform in order to identify any anomalous situation which may cause impairments to other
systems.
The overall result of these checks and verifications are contained in a functional variable which shall be
called Self Monitoring Variable (SMV). The states of this variable are "Pass" and "Fail".
The state of the SMV may change as a result of events. These are:
- Status Monitoring Pass event (SMP);
- Status Monitoring Fail event (SMF).
The circumstances under which these events may take place are specified in subclause 5.3.1 of this ETS.
b) Control function: this function is associated with the ability of the CCMF to inhibit and to permit
transmissions from an individual VSAT as specified in ETS 300 161 [2].
This function is reflected in the state of a functional variable, resident at each VSAT named Control
Variable .
The states of this variable are "enable" and "disable".
The Control Variable may change as a result of events. These are:
- Central Control Disable (CCD);
- Central Control Enable (CCE).
The circumstances associated to the reception of the messages resulting in these events are specified in
subclause 5.3.2 of this ETS.

Besides these two sets of control and monitoring functions, the VSATs are requested to achieve a
controlled non transmitting state following the activation of the terminal (power on).
VSATs that allow local operator intervention may include a terminal reset function which when actuated
results in a Reset Event (RE).
Subclause 5.3.3 specifies the functions associated to the occurrence of the "p
