Technical characteristics and methods of measurement for equipment for generation, transmission and reception of Digital Selective Calling (DSC) in the maritime MF, MF/HF and/or VHF mobile service - Part 6: Class M DSC
The present document states the minimum requirements for devices using Digital Selective Calling (DSC) Class M, for
Man Overboard (MOB). The present document defines the requirements for equipment that uses DSC alerting and
signalling in the maritime mobile bands and particularly the GMDSS distress and safety channels. Such equipment is
not intended to provide any subsequent communications or telephony facilities.
The present document is part 6 of a multi-part deliverable that covers the channel access rules and technical
requirements applicable to these devices.

class M: specific class of DSC functionality for use by man overboard devices
closed loop: individual transmission to own vessel
default: value selected or an action taken by the equipment software in the absence of any operator input
distress alert: name given to the single distress DSC message with the format symbol 112
distress DSC message: DSC message or acknowledgement containing the distress information
distress information: symbols within a DSC message describing a distress situation consisting of the MMSI of the
vessel in distress, the nature of distress, the position of the vessel in distress, the UTC time of that position and the mode
of subsequent communication
factory default: default value that is set by the manufacturer such that the field or behaviour is defined prior to any
operator intervention
information characters: set of symbols in a DSC message that contains the items of interest for the recipient and is
used to compute the ECC symbol that terminates the message
non distress DSC message: DSC messages or acknowledgements that do not have the format specifier or category of
"distress"
open loop: transmitting to all ships (broadcast) 'using All ships call types'
symbol (as part of the DSC sentence): 7 binary bits of a 10 bit DSC word that have the information content
test mode: self-testing mode using an individual test call to own vessel
word (as part of the DSC sentence): 10 binary bits that make up the coded entities of a transmitted DSC message

1 Scope
The present document states the minimum requirements for devices using Digital Selective Calling (DSC) Class M, for
Man Overboard (MOB). The present document defines the requirements for equipment that uses DSC alerting and
signalling in the maritime mobile bands and particularly the GMDSS distress and safety channels. Such equipment is
not intended to provide any subsequent communications or telephony facilities.
The present document is part 6 of a multi-part deliverable that covers the channel access rules and technical
requirements applicable to these devices.

1 Scope
The present document states the minimum requirements for devices using Digital Selective Calling (DSC) Class M, for
Man Overboard (MOB). The present document defines the requirements for equipment that uses DSC alerting and
signalling in the maritime mobile bands and particularly the GMDSS distress and safety channels. Such equipment is
not intended to provide any subsequent communications or telephony facilities.
The present document is part 6 of a multi-part deliverable that covers the channel access rules and technical
requirements applicable to these devices.

3 Definition of terms, symbols and abbreviations
3.1 Terms
For the purposes of the present document, the terms given in ETSI EN 300 338-1 [i.1] and the following apply:
acknowledged: automated procedure which indicates that the objective of the initial DSC message has been achieved
activation: initial triggering of the MoB device i.e. both parts of the two step procedure are performed
active mode: activated mode, transmitting in an emergency situation
class M: specific class of DSC functionality for use by man overboard devices
closed loop: individual transmission to own vessel
default: value selected or an action taken by the equipment software in the absence of any operator input
distress alert: name given to the single distress DSC message with the format symbol 112
distress DSC message: DSC message or acknowledgement containing the distress information
distress information: symbols within a DSC message describing a distress situation consisting of the MMSI of the
vessel in distress, the nature of distress, the position of the vessel in distress, the UTC time of that position and the mode
of subsequent communication
factory default: default value that is set by the manufacturer such that the field or behaviour is defined prior to any
operator intervention
information characters: set of symbols in a DSC message that contains the items of interest for the recipient and is
used to compute the ECC symbol that terminates the message
non distress DSC message: DSC messages or acknowledgements that do not have the format specifier or category of
"distress"
open loop: transmitting to all ships (broadcast) 'using All ships call types'
symbol (as part of the DSC sentence): 7 binary bits of a 10 bit DSC word that have the information content
test mode: self-testing mode using an individual test call to own vessel
word (as part of the DSC sentence): 10 binary bits that make up the coded entities of a transmitted DSC message
NOTE: The 10 bits consist of a 7 bit "symbol" that gives the information content and 3 bit error check that gives
the number of 0 binary bits in the 7 bit symbol.
