1 Scope
The present document states the minimum requirements for equipment to be used for generation, transmission and
reception of Class A or B Digital Selective Calling (DSC) for use on board ships.
DSC is intended to be used in the Medium Frequency (MF), High Frequency (HF) and Very High Frequency (VHF)
bands of the Maritime Mobile Service (MMS), for both distress, safety and general communications.
The present document is part 2 of a multi-part deliverable that covers the requirements to be fulfilled by equipment that
is either integrated with a transmitter and/or a receiver or equipment that is a stand-alone DSC terminal and has the
following class of DSC:
• Class A: includes all the facilities defined in annex 1 of Recommendation ITU-R M.493-14 [3] and complies
with the IMO Global Maritime Distress and Safety System (GMDSS) carriage requirements for MF/HF
installations and/or VHF installations;
• Class B: provides minimum facilities for equipment on ships not required to use class A equipment and
complies with the minimum IMO GMDSS carriage requirements for MF and/or VHF installations. This
equipment should provide for:
- alerting, acknowledgement and relay facilities for distress purposes;
- calling and acknowledgement for general communication purposes; and
- calling in connection with semi-automatic/automatic services, as defined in Recommendation ITU-R
M.493-14 [3], annex 2, clause 3.
These requirements include the relevant provisions of the ITU Radio Regulations [2] and Recommendations ITU-R, the
International Convention for the Safety Of Life At Sea (SOLAS), and the relevant resolutions of the International
Maritime Organization (IMO).

3 Definitions and abbreviations
3.1 Definitions
For the purposes of the present document, the terms and definitions given in ETSI EN 300 338-1 [i.1] and the following
apply:
acknowledged: when the objective of the initial DSC message has been achieved
active: automated procedure which has control of the general receiver and transmitter and is thus able to engage in
subsequent communications and receive DSC messages on both the watch receiver and general receiver
automated procedure: set of actions necessary to complete the objective of an initiating DSC message or non DSC
communication event
NOTE 1: Four DSC automated procedures are designed to process these. They are the receiving of distress DSC
messages, the receiving of non-distress DSC messages, the sending of distress DSC alert attempts and the
sending of non-distress DSC messages. In addition a fifth procedure is designed to handle non DSC
communication events.
NOTE 2: These automated procedures are called:
Received distress automated procedure.
Sending distress automated procedure.
Received non-distress automated procedure.
Sending non-distress automated procedure.
Communications automated procedure.
default: value selected or an action taken by the equipment software in the absence of any operator input
distress DSC message: DSC message or acknowledgement containing the distress information
distress event: unique distress situation identified by two (VHF) or three (MF/HF) parameters of the distress
information; the MMSI of the vessel in distress and the nature of distress and on MF/HF the mode of subsequent
communication
ETSI

engaged: equipment that is busy handling an automated procedure
factory default: default value that is set by the manufacturer such that the field or behaviour is defined prior to any
operator intervention
general receiver: receiver part of the transceiver used for the reception of all subsequent communications and on HF
the reception of DSC acknowledgements on the duplex DSC channels
NOTE: It is important to distinguish this unit from the watch receiver.
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
NOTE: These symbols are repeated in the DX/RX time diversity pattern.
initial DSC message: DSC message that starts an automated procedure
non-distress DSC message: DSC messages or acknowledgments that do not have the format specifier or category of
"distress"
objective: intent of the DSC message either to establish subsequent communications or request information
on hold: automated procedure which does not have access to the transmitter and general receiver and therefore cannot
engage in subsequent communications and is only able to receive DSC messages on the watch receiver
operator options: any choices the operator can make while the automated procedure is engaged
parallel event handling: backgro

1 Scope
The present document states the minimum requirements for equipment to be used for generation, transmission and
reception of Class A or B Digital Selective Calling (DSC) for use on board ships.
DSC is intended to be used in the Medium Frequency (MF), High Frequency (HF) and Very High Frequency (VHF)
bands of the Maritime Mobile Service (MMS), for both distress, safety and general communications.
The present document is part 2 of a multi-part deliverable that covers the requirements to be fulfilled by equipment that
is either integrated with a transmitter and/or a receiver or equipment that is a stand-alone DSC terminal and has the
following class of DSC:
• Class A: includes all the facilities defined in annex 1 of Recommendation ITU-R M.493-14 [3] and complies
with the IMO Global Maritime Distress and Safety System (GMDSS) carriage requirements for MF/HF
installations and/or VHF installations;
• Class B: provides minimum facilities for equipment on ships not required to use class A equipment and
complies with the minimum IMO GMDSS carriage requirements for MF and/or VHF installations. This
equipment should provide for:
- alerting, acknowledgement and relay facilities for distress purposes;
- calling and acknowledgement for general communication purposes; and
- calling in connection with semi-automatic/automatic services, as defined in Recommendation ITU-R
M.493-14 [3], annex 2, clause 3.
These requirements include the relevant provisions of the ITU Radio Regulations [2] and Recommendations ITU-R, the
International Convention for the Safety Of Life At Sea (SOLAS), and the relevant resolutions of the International
Maritime Organization (IMO).

apply:
acknowledged: when the objective of the initial DSC message has been achieved
active: automated procedure which has control of the general receiver and transmitter and is thus able to engage in
subsequent communications and receive DSC messages on both the watch receiver and general receiver
automated procedure: set of actions necessary to complete the objective of an initiating DSC message or non DSC
communication event
NOTE 1: Four DSC automated procedures are designed to process these. They are the receiving of distress DSC
messages, the receiving of non-distress DSC messages, the sending of distress DSC alert attempts and the
sending of non-distress DSC messages. In addition a fifth procedure is designed to handle non DSC
communication events.
NOTE 2: These automated procedures are called:
Received distress automated procedure.
Sending distress automated procedure.
Received non-distress automated procedure.
Sending non-distress automated procedure.
Communications automated procedure.
default: value selected or an action taken by the equipment software in the absence of any operator input
distress DSC message: DSC message or acknowledgement containing the distress information
distress event: unique distress situation identified by two (VHF) or three (MF/HF) parameters of the distress
information; the MMSI of the vessel in distress and the nature of distress and on MF/HF the mode of subsequent
