三、阅读理解
PASSAGE1.Basic description of DSC:DSC is basically a calling system .Each call consists of a “packet” of digitized information of one of four priorities : Distress , Urgency , Safety , Routine :Message can be routed to “all stations”, to an individual station or to a group of stations, using their Maritime Mobile Selective-call Identify code (MMSI):Distress messages are automatically broadcast to “All stations”. In addition to the MMSI of source and destination stations, information can be conveyed in the DSC message:For example, to aid the Rescue Service, the DSC Distress alert message is configured to contain the following: A\Ship’s identify (the nine digit MMSI) B\Time. C\ Nature of distress (in the form of standard code) D\Ship’s position.Where fitted ship’s officers should ensure they are fully conversant with the procedure for entering the necessary information into DSC equipment:At sea, unless provided automatically from a navigation system, ship’s position should be update at least once during each watch period.
