REN/ERM-TG26-087-4

Tehnične karakteristike in merilne metode za naprave, ki generirajo, oddajajo in sprejemajo digitalni selektivni klic (DSC) v pomorski mobilni storitvi, ki deluje v območju MF, MF/HF oziroma VHF - 4. del: Digitalni selektivni klic razreda E

V tem dokumentu so navedene minimalne zahteve za splošno komunikacijo z ladijskimi stacionarnimi napravami, ki uporabljajo digitalno selektivno klicanje razreda E.
Digitalno selektivno klicanje razreda E je namenjeno za uporabo v pasovih srednje in/ali visoke frekvence pomorske mobilne storitve (MMS) za zasilno, nujno in varnostno komunikacijo ter splošno komunikacijo z uporabo telefonije za naknadno komunikacijo.
Ta dokument je 4. del večdelnega dokumenta, ki obravnava zahteve, ki jih morajo izpolnjevati naprave, vgrajene v oddajniku in/ali sprejemniku, oziroma samostojne naprave s terminalom za digitalno selektivno klicanje.
Te zahteve vključujejo zadevne določbe in smernice Mednarodne pomorske organizacije, kot je opredeljeno v MSC/Circ.803 [i.1] za plovila, ki niso zajeta z Mednarodno konvencijo o varstvu človeškega življenja na morju ter so del globalnega pomorskega zasilnega in varnostnega sistema, ter odločbe Komisije z dne 4. septembra 2003 (2004/71/ES [i.3]).

1 Scope
The present document states the minimum requirements for general communication for shipborne fixed installations using
DSC - class E.
Class E DSC is intended to be used in the Medium Frequency (MF) and/or High Frequency (HF) bands of the Maritime
Mobile Service (MMS), for distress, urgency and safety communication and general communications and uses
telephony for subsequent communications.
The present document is part 4 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.
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 [i.3]).

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.2] and the following
apply:
acknowledged: automated procedure that indicates 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.
block: inhibit a function by making it inaccessible from the user interface
class E: DSC class intended to provide minimum facilities for MF/HF DSC distress, urgency and safety as well as
routine calling and reception, not necessarily in full accordance with IMO GMDSS carriage requirements for MF
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: 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: transceiver used for the reception of all subsequent communications
NOTE: It is important to distinguish this unit from the watch receiver.
ETSI

9 ETSI EN 300 338-4 V1.2.1 (2017-02)
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
operator options: any choices the operator can make while the automated procedure is engaged
pertinent to the automated procedure: DSC messages that have something to do with the procedure and are 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 radio 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

apply:
acknowledged: automated procedure that indicates 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.
block: inhibit a function by making it inaccessible from the user interface
class E: DSC class intended to provide minimum facilities for MF/HF DSC distress, urgency and safety as well as
routine calling and reception, not necessarily in full accordance with IMO GMDSS carriage requirements for MF
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: 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: transceiver used for the reception of all subsequent communications
NOTE: It is important to distinguish this unit from the watch receiver.
