ETSI ETSI EN 300 338-4 V1.2.1 (2017-02) 7 1 Scope The present document states the minimum requirements for general communicati
29、on 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
30、 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
31、 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). 2 References 2.1 Normative references References are either specific (identified by date of publication and/or edition numb
