25、part deliverable covering Digital Selective Calling (DSC), as identified below: Part 1: “Common requirements“; Part 2: “Class A/B DSC“; Part 3: “Class D DSC“; Part 4: “Class E DSC“. The present document covers the operator interfaces and operating system for Class A/B DSC equipment. National transpo

27、ETSI ETSI EN 300 338-2 V1.3.1 (2010-02) 71 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), H
28、igh 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 tra
29、nsmitter 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 ITU-R Recommendation M.493-12 3 and complies with the IMO Global Maritime Distress and Safety System (GMDSS) carriage requirements
30、 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, acknowled
31、gement 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 ITU-R Recommendation M.493-12 3, annex 2, clause 3. These requirements include the relevant provision
32、s of the ITU Radio Regulations 2 and ITU-R Recommendations, the International Convention for the Safety Of Life At Sea (SOLAS) 1, and the relevant resolutions of the International Maritime Organization (IMO). 2 References References are either specific (identified by date of publication and/or editi

They are the receiving of distress DSC messages, the receiving of non distress DSC message
42、s, 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.
