SIST EN 300 338-1 V1.6.1:2021

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 1: Common requirements

The present document states the minimum requirements for equipment to be used for generation, transmission and
reception of Digital Selective Calling (DSC) for use on board ships.
DSC is intended to be used in the Medium Frequency (MF), High Frequency (HF) and Very High Frequency (VHF)
bands of the Maritime Mobile Service (MMS), for distress, urgency and safety communication and general
communications.
The present document is part 1 of a multi-part deliverable that covers the requirements to be fulfilled by:
• DSC equipment integrated with a transmitter and/or a receiver;
• DSC equipment not integrated with a transmitter and/or a receiver.
These requirements include the relevant provisions of the ITU Radio Regulations [i.15] and Recommendations ITU-R
M.493-15 [2], M.541-10 [3], M.689-3 [4] and M.1082-1 [5], the International Convention for the Safety Of Life At Sea
(SOLAS) [i.14], and the following resolutions/circulars of the International Maritime Organization (IMO):
A.694(17) [14], A.803(19) [15] amended by MSC.68(68) Annex 1 [17], A.804(19) [16], MSC.68(68) Annex 2 [17],
A.806(19) [18], MSC.68(68) Annex 3 [17], MSC 302(87) [12] and MSC/Circ.862 [19].
Equipment for generation, transmission and reception of DSC designed according to the following equipment classes:
• Class A: includes all the facilities defined in annex 1 of Recommendation ITU-R M.493-15 [2] and complies
Performance Standards A.803(19) for VHF [15], A.804(19) for MF [16] and A.806(19) for MF/HF equipment
capable of voice and DSC [18].
• Class D: provides minimum facilities for VHF DSC distress, urgency and safety as well as routine calling and
reception as recommended by IMO MSC/Circ.803 [i.2] for non-SOLAS vessels participating in the GMDSS
and defined by Recommendation ITU-R M.493-15 [2].
• Class E: provides minimum facilities for MF and/or HF DSC distress, urgency and safety as well as routine
calling and reception as recommended by IMO MSC/Circ.803 [i.2] for non-SOLAS vessels participating in the
GMDSS and Recommendation ITU-R M.493-15 [2].
• Class H: provides minimum facilities for handheld VHF DSC distress, urgency and safety as well as routine
calling and reception as recommended by IMO MSC/Circ.803 [i.2] for non-SOLAS vessels participating in the
GMDSS and Recommendation ITU-R M.493-15 [2].
• Class M: provides minimum facilities for VHF Man Overboard devices as defined in Recommendation
ITU-R M.493-15 [2].
NOTE 1: Class A equipment may support the optional semi-automatic/automatic service in accordance with
Recommendations ITU-R M.689-3 [4], M.1082-1 [5] and M.493-15 [2], tables A1-4.10.1 and A1-4.10.2
and are encouraged to do so.
NOTE 2: Class D and Class E equipment may also support the optional semi-automatic/automatic service.
NOTE 3: Class D, Class E, Class H should provide a defined list of functions as a closed list for these classes of
equipment is the preferable approach to ensure safe and simple operation. Optional functions should be
avoided, with the intention to provide the same functionality of all equipment of one class.
