27、National Standard (dow): 30 November 2010 ETSI ETSI EN 300 338-4 V1.1.1 (2010-02) 71 Scope The present document states the minimum requirements for general communication for shipborne fixed installations using DSC - class E. Class E DSC is intended to be used in the Medium Frequency (MF) and/or High
28、 Frequency (HF) bands of the Maritime Mobile Service (MMS), for distress, urgency and safety communication and general communications and uses telephony for subsequent communications. The present document is part 4 of a multi-part deliverable that covers the requirements to be fulfilled by equipment
29、 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 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 Dec

They are the receiving of distress
