Technical characteristics and methods of measurement for equipment for generation, transmission and reception of Digital Selective Calling (DSC) in the maritime MF, MF/HF and/or VHF mobile service - Part 3: Class D DSC

The present document states the minimum requirements for general communication for shipborne fixed installations using
DSC - class D.
Class D DSC is intended be used in the Very High Frequency (VHF) band of the Maritime Mobile Service (MMS), for
distress, urgency and safety communication and general communications using telephony for subsequent
communications.
The present document is part 3 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 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 12 August 2013
(2013/638/EU) [i.5].

1 Scope

The present document states the minimum requirements for general communication for shipborne fixed installations using

DSC - class D.

Class D DSC is intended be used in the Very High Frequency (VHF) band of the Maritime Mobile Service (MMS), for

distress, urgency and safety communication and general communications using telephony for subsequent

communications.

The present document is part 3 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 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 12 August 2013

(2013/638/EU) [i.5].

3 Definition of terms, symbols and abbreviations
3.1 Terms

For the purposes of the present document, the terms given in ETSI EN 300 338-1 [i.2] and the following apply:

acknowledged: automated procedure which indicates that the objective of the initial DSC message has been achieved

active: automated procedure which has control of the general receiver and transmitter and is thus able to engage in

subsequent communications and receive DSC messages on both the watch receiver and general receiver

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 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:
 received distress automated procedure;
 sending distress automated procedure;
 received non-distress automated procedure;
 sending non-distress automated procedure;
 communications automated procedure.
class D: class of DSC intended to provide

7 Final draft ETSI EN 300 338-3 V1.3.1 (2020-03)
1 Scope

The present document states the minimum requirements for general communication for shipborne fixed installations using

DSC - class D.

Class D DSC is intended be used in the Very High Frequency (VHF) band of the Maritime Mobile Service (MMS), for

distress, urgency and safety communication and general communications using telephony for subsequent

communications.

The present document is part 3 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 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 12 August 2013

(2013/638/EU) [i.5].

3.1 Terms

For the purposes of the present document, the terms given in ETSI EN 300 338-1 [i.2] and the following apply:

acknowledged: automated procedure which indicates that the objective of the initial DSC message has been achieved

active: automated procedure which has control of the general receiver and transmitter and is thus able to engage in

subsequent communications and receive DSC messages on both the watch receiver and general receiver

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 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:
 received distress automated procedure;
 sending distress automated
