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. class D: intended to provide minimum facilities for VHF DSC distress, urgency and safety as well as routine calling and reception, not necessarily in full accordance with IMO GMDSS carriage requirements for VHF installations 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 parameters of the distress information; the MMSI of the vessel in distress and the nature of distress engaged: used to indicate that the equipment 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 SIST EN 300 338-3 V1.1.1:2010

1 Scope
The present document states the minimum requirements for general communication for shipborne fixed installations using
DSC - class D.
Class D DSC is intended be used in the Very High Frequency (VHF) band of the Maritime Mobile Service (MMS), for
distress, urgency and safety communication and general communications using telephony for subsequent
communications.
The present document is part 3 of a multipart 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.
These requirements include the relevant provisions and the guidelines of the IMO as detailed in MSC/Circ.803 [i.1] for
non-SOLAS vessels participating in the GMDSS as well as Commission Decision of 4 September 2003 (2004/71/EC [3]).

3 Definitions and abbreviations
3.1 Definitions
For the purposes of the present document, the terms and definitions given in EN 300 338-1 [i.2] and the following
apply:
acknowledged: automated procedure it indicates that 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.
class D: intended to provide minimum facilities for VHF DSC distress, urgency and safety as well as routine calling
and reception, not necessarily in full accordance with IMO GMDSS carriage requirements for VHF installations
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 parameters of the distress information; the MMSI of the
vessel in distress and the nature of distress
engaged: used to indicate that the equipment 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
ETSI
---------------------- Page: 8 ----------------------
9 ETSI EN 300 338-3 V1.1.1 (2010-02)
general receiver: receiver part of the transceiver used for the reception of all subsequent communications
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: when in reference to a DSC message or automated procedure, the goal or intent of the item
NOTE: Usually this goal or intent is to establish subsequent communications or request information.
operator options: any choices the operator can make while the automated procedure is engaged
pertinent to the automated procedure: expression used primarily with reference to DSC messages to indicate that the
message has something to do with the procedure and is therefore 'handled' by the procedure
NOTE: A DSC message is pertinent to an automated procedure if the set of information characters in the DSC
message has the correct values.
pertinent to the station: any DSC message that would start an automated procedure if the transceiver were in standby
self-terminating alarm: short alarm that stops by itself without operator intervention
NOTE: The purpose of this alarm is to inform the operator that a DSC message is received but it does not require
his immediate attention.
symbol (as part of the DSC sentence): 7 binary bits of a 10 bit DSC word that have the information content
top level: means that items, buttons, or functions are present and visible without requiring any action by the operator
(such as scrolling, opening up menus, or removing any obscuring covers, etc.).
two-tone alarm: alarm consisting of a repetition of the 2 200 Hz frequency for 250 ms followed by a 1 300 Hz
frequency for 250 ms
NOTE: This alarm is used for the initiation of the received distress DSC automated procedure.
urgency alarm: alarm consisting of a repetition of the 2 200 Hz frequency for 250 ms followed by 250 ms period of
silence
NOTE: This alarm is used for the initiation of the received non distress DSC automated procedure when the
category of the initiating DSC message is "urgency".
watch receiver: separate receiver in DSC radios that continuously monitors VHF channel 70
word (as part of the DSC sentence): used to describe the 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.

1 Scope
The present document states the minimum requirements for general communication for shipborne fixed installations using
DSC - class D.
Class D DSC may be used in the Very High Frequency (VHF) Maritime Mobile Service (MMS), for distress, urgency
and safety communication and general communications using telephony for subsequent communications.
The present document is part 3 of a multipart standard 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.
These requirements include the relevant provisions and the guidelines of the IMO as detailed in MSC/Circ.803 [i.1] for
non-SOLAS vessels participating in the GMDSS.

3 Definitions and abbreviations
3.1 Definitions
For the purposes of the present document, the following terms and definitions apply:
acknowledged: automated procedure it indicates that 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.
class D: intended to provide minimum facilities for VHF DSC distress, urgency and safety as well as routine calling
and reception, not necessarily in full accordance with IMO GMDSS carriage requirements for VHF installations
critical errors: set of information characters obtained from one or more received DSC messages is considered to have
critical errors if the automated procedure needs information characters from that set in order to proceed or perform any
task, but the required information characters are in error
EXAMPLE: An acknowledgement cannot be composed to an individual DSC message that has errors in the
sender's MMSI.
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

9 Draft ETSI EN 300 338-3 V1.1.1 (2008-12)
distress alert attempt: set of distress alerts sent by a vessel when in distress
NOTE: A distress alert DSC message by itself is never intentionally sent by a vessel in distress. For example, the
single frequency distress alert attempt consists of five consecutive distress alerts with no break in between
each distress alert.
distress DSC message: DSC message or acknowledgement containing the distress information
distress event: unique distress situation identified by two parameters of the distress information; the MMSI of the
vessel in distress and the nature of distress
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
engaged: used to indicate that the equipment 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
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: when in reference to a DSC message or automated procedure, the goal or intent of the item
NOTE: Usually this goal or intent is to establish subsequent communications or request information.
operator options: any choices the operator can make while the automated procedure is engaged
pertinent to the automated procedure: expression used primarily with reference to DSC messages to indicate that the
message has something to do with the procedure and is therefore 'handled' by the procedure
NOTE: A DSC message is pertinent to an automated procedure if the set of information characters in the DSC
message has the correct values.
pertinent to the station: any DSC message that would start an automated procedure if the transceiver were in standby
self-terminating alarm: short alarm that stops by itself without operator intervention
NOTE: The purpose of this alarm is to inform the operator that a DSC message is received but it does not require
his immediate attention.
standby: equipment is not handling an automated procedure, either active or on hold, but is able to receive DSC
messages
symbol (as part of the DSC sentence): 7 binary bits of a 10 bit DSC word that have the information content
top level: means that items, buttons, or functions are present and vis
