27、National Standard (dow): 30 November 2011 ETSI ETSI EN 300 338-5 V1.1.1 (2011-02) 71 Scope The present document states the minimum requirements for general communication for handheld VHF radios using the handheld class D DSC for shipborne use. Class D DSC may be used in the Very High Frequency (VHF)
28、 Maritime Mobile Service (MMS), for distress, urgency and safety communication and general communications using telephony for subsequent communications. The present document is part 5 of a multipart standard that covers the requirements to be fulfilled by equipment that is integrated with a handheld
29、 transceiver. 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. 2 References References are either specific (identified by date of publication and/or edition number or version number) or

ETSI ETSI EN 300 338-5 V1.1.1 (2011-02) 83 Definitions and abbreviations 3.1 Definitions For the purposes of the present document, the follow
35、ing 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 receiver and transmitter and is thus able to engage in subsequent communications and receive DSC messag
36、es 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
37、 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: square4 Received distress automated procedure. square4 Sending distress automated pro
38、cedure. square4 Received non-distress automated procedure. square4 Sending non-distress automated procedure. square4 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
39、in full accordance with IMO GMDSS carriage requirements for VHF installations NOTE: For handheld VHF a reduced functionality is permitted compared to a fixed VHF class D. critical errors: set of information characters obtained from one or more received DSC messages is considered to have critical err
40、ors 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 senders MMSI. default: value sele
41、cted 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 distress alert attempt: set of distress alerts sent by a vessel when in distress NOTE: A distress alert DSC message by itsel
42、f 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
43、 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
44、 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 ETSI ETSI EN 300 338-5 V1.1.1 (2011-02) 9factory default: default value that is set by the ma
45、nufacturer such that the field or behaviour is defined prior to any operator intervention 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 i
46、n the DX/RX time diversity pattern. initial DSC message: DSC message that starts an automated procedure non distress DSC message: DSC messages or acknowledgements that do not have the format specifier or category of “distress“ objective: when in reference to a DSC message or automated procedure, the
47、 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
48、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 m
49、essage 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, but
