SIST ETS 300 160 E1:2006
(Main)Satellite Earth Stations and Systems (SES); Control and monitoring functions at a Very Small Aperture Terminal (VSAT)
- Abstract
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.

SIST ETS 300 160 E1:2006 is the Slovenian standard identical to ETS 300 160 Edition 1 from ETSI. It specifies control and monitoring functions for two-way Very Small Aperture Terminal (VSAT) satellite earth stations in digital satellite networks, with the aim of limiting interference caused by faults at the terminal. It is written for VSAT equipment and network systems that need defined local monitoring, central enable/disable control, and transmission validation.
What does SIST ETS 300 160 E1:2006 specify?
SIST ETS 300 160 E1:2006 specifies the control and monitoring functions for the satellite access subsystem of a two-way VSAT. It applies to VSATs used in digital communication networks operating with a separate Centralised Control and Monitoring Functions (CCMF) entity.
The scope covers VSATs in star, mesh, and point-to-point network configurations. The document focuses on operating behavior and interference control, not on installation.
The document is organized into:
- scope
- normative references
- definitions
- abbreviations
- requirements
Figure 1 gives the state transition model used in the requirements.
What are the key requirements of SIST ETS 300 160 E1:2006?
SIST ETS 300 160 E1:2006 sets a minimum behavior model for a VSAT so that a fault does not leave it transmitting when it should not. The requirements center on a monitoring function, a central control function, and defined non-transmitting states.
Monitoring and control model
The VSAT uses a Self Monitoring Variable (SMV) with the states Pass and Fail, and a Control Variable with the states enable and disable. In practice, this means the terminal always has to know whether it is healthy enough to transmit and whether the network currently authorizes transmission.
The combination of SMV and Control Variable defines four states:
- Out of Service
- Checking
- Stand by
- In Service
These states matter because they determine whether the VSAT may transmit or must stay silent.
Self-monitoring functions
Clause 5.3.1 requires self-monitoring of:
- processor operation
- receive subsystem operation
- transmit frequency generation
- reception of the control channel
- VSAT transmission validation
If any monitored condition fails, the SMV changes to Fail and the VSAT must move to a non-transmitting state within a defined time. In practice, the manufacturer has to show by evidence and demonstration that the terminal suppresses transmission when a processor fault, receive fault, or transmit fault occurs.
Clause 5.3.1.4 also requires the VSAT to store, in non-volatile memory, the identity of its authorized control channel or channels and its own identification code. That is what lets the network address the right terminal and keep control traffic on the correct satellite path.
Central control functions
Clause 5.3.2 covers the CCMF messages that authorize or inhibit transmission. A Central Control Enable (CCE) message moves the VSAT toward transmission authorization, and a Central Control Disable (CCD) message forces suppression of transmission.
This matters for operations because the network can stop a terminal from transmitting even if the terminal itself is healthy, for example during maintenance or fault handling.
Power on and reset behavior
Clause 5.3.3 requires the VSAT to enter a controlled non-transmitting state after power on. If the terminal supports a local reset, the reset event also moves it to Out of Service within a defined time. In practice, this prevents a rebooted terminal from radiating before it has checked itself and received authorization.
Transmission validation
Clause 5.3.1.5 gives two ways to confirm that transmitted signals are being received correctly:
- validation by the CCMF
- validation by receiving station(s)
This gives operators a way to confirm end-to-end operation, either through centralized polling/status exchange or through feedback from the receiving side.
State-specific behavior
Clause 5.2 ties the states to transmit permission:
- Checking - no transmission
- Out of Service - no transmission
- Stand by - no transmission
- In Service - transmission allowed
For a terminal with multiple carriers, a separate state machine may be applied to each carrier. That is important where one VSAT supports more than one transmission path.
What terms does SIST ETS 300 160 E1:2006 define?
SIST ETS 300 160 E1:2006 defines the core control words used throughout the requirements.
- VSAT - Very Small Aperture Terminal, the satellite earth station covered by the standard.
- CCMF - Centralised Control and Monitoring Functions, the system-level function that controls and supervises VSATs.
- SMV - Self Monitoring Variable, the local pass/fail status of the VSAT monitoring function.
- SMP - Status Monitoring Pass event, the event that sets or supports a passing monitoring state.
- SMF - Status Monitoring Fail event, the event that reflects a monitoring failure.
- CCE - Central Control Enable, the event created by a control message that permits transmission.
- CCD - Central Control Disable, the event created by a control message that inhibits transmission.
- RE - Reset Event, the event associated with a local reset.
Who uses SIST ETS 300 160 E1:2006?
SIST ETS 300 160 E1:2006 is used by manufacturers designing VSAT terminals, by network operators running VSAT networks, and by test or approval bodies checking whether a terminal behaves safely under fault and control conditions. It is also relevant to system integrators who need the terminal state model to match the CCMF functions defined for the network.
Which standards are used with SIST ETS 300 160 E1:2006?
SIST ETS 300 160 E1:2006 depends on two cited ETS documents:
- ETS 300 159 - defines transmit/receive VSATs used for data communications in the Fixed Satellite Service (FSS) 11/12/14 GHz bands. It provides the network context and the VSAT type to which this standard applies.
- ETS 300 161 - specifies the Centralised Control and Monitoring Functions for VSAT networks. It supplies the CCMF behavior that sends enable/disable control and status polling.
What does the SIST ETS 300 160 E1:2006 document contain?
SIST ETS 300 160 E1:2006 contains the functional model, state definitions, and compliance checks for VSAT control and monitoring. It uses a state transition diagram in Figure 1 to show how the terminal moves between Out of Service, Checking, Stand by, and In Service.
The requirements section also describes what a manufacturer has to verify by documentary evidence and demonstration. That includes processor monitoring, receive and transmit subsystem checks, control channel handling, central enable and disable messages, transmission validation, and power-on or reset behavior.

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).
