3 Definition of terms, symbols and abbreviations
3.1 Terms
For the purposes of the present document, the following terms apply:
class M: specific class of DSC functionality for use by man overboard devices
ETSI

---------------------- Page: 5 ----------------------
6 ETSI TS 101 570-2 V1.2.1 (2020-02)
closed loop: class M individual transmission to own vessel
leap second: second which is occasionally inserted into the atomic scale of reckoning time in order to bring it into line
with solar time
open loop: class M transmitting to all ships (broadcast) 'using All ships call types'
3.2 Symbols
Void.
3.3 Abbreviations
For the purposes of the present document, the abbreviations given in ETSI EN 300 338-1 [i.2] and the following apply:
AIS Automatic Identification System
CF (Test) ConFiguration
EUT Equipment Under Test
GNSS Global Navigation Satellite System
MOB Man OverBoard
NACK Negative ACKnowledgement
QE Qualified Equipment (i.e. DSC standards compliant)
TD Test Description
TP Test Purpose
TSS Test Suite Structure
UTC Universal Time Co-ordinated
4 Test Configurations
This clause defines all test configurations used. Each test description refers to one or multiple test configurations. It is
assumed that the initial state of all the equipment involved in the test configuration is 'standby' for DSC radios or
'deactivated' for MOB devices, i.e. unless stated otherwise the pre-test conditions of each test description assume
standby/idle mode for the equipment.
An arrow connection between devices indicates that these devices are in communication range, i.e. in CF_VHF_6 EUT,
QE1 and QE2 are all in the same communication range. However, QE3 is only in communication range with QE2.
