ETSI ETSI EN 300 338-2 V1.4.1 (2017-02) 7 1 Scope The prese
29、nt 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
30、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-al
31、one 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
32、: 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; - calli
33、ng 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
34、, the International Convention for the Safety Of Life At Sea (SOLAS), and the relevant resolutions of the International Maritime Organization (IMO). 2 References 2.1 Normative references References are either specific (identified by date of publication and/or edition number or version number) or non

43、e 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
44、 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
45、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: square4 Received distress automated procedure. square4 Sending distress automated procedure. square4 Received non-distress automated
46、procedure. square4 Sending non-distress automated procedure. square4 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
47、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 ETSI EN 300 338-2 V1.4.1 (2017-02) 9 engaged: equipment that
48、 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
