General

The present document states the minimum requirements for equipment to be used for generation, transmission and 
reception of Class D Digital Selective Calling (DSC) for shipborne fixed installations. 
The present document covers the operator interfaces and operating system for Class D DSC equipment. 
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 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 IMO Circular 
MSC.1/Circ.803 Rev.1 [i.1] for non-SOLAS vessels participating in the GMDSS as well as Commission Decision of 
12 August 2013 (2013/638/EU) [i.5].

The present document states the minimum requirements for general communication for shipborne fixed installations using 
DSC - class E. 
The present document covers the operator interfaces and operating system for Class E DSC equipment. 
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 communications. 
The present document 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 IMO Circular 
MSC.1/Circ.803/Rev.1 [i.1] for non-SOLAS vessels participating in the GMDSS as well as Commission Decision of 
12 August 2013 (2013/638/EU) [i.3].

The present document states the minimum requirements for general communication for handheld VHF radios using the 
handheld class H DSC for shipborne use. 
Class H DSC may be used in the Very High Frequency (VHF) Maritime Mobile Service (MMS), for distress, urgency 
and safety communication and general communications using telephony for subsequent communications. 
The present document covers the requirements to be fulfilled by equipment that is integrated with a handheld 
transceiver. 
These requirements include the relevant provisions and the guidelines of the IMO as detailed in IMO MSC/Circ.803 [i.1] for 
non-SOLAS vessels participating in the GMDSS.

The present document states the minimum requirements for Man Overboard (MOB) devices using Digital Selective 
Calling (DSC) Class M, AMRD Group A as defined in Annex 1 of Recommendation ITU-R M.2135-1 [i.1]. The present 
document also defines the requirements for equipment that uses DSC alerting and signalling in the maritime mobile 
bands and particularly the GMDSS distress and safety channels. Such equipment is not intended to provide any 
subsequent communications or telephony facilities. 
The present document covers the channel access rules and technical requirements applicable to these devices. 

The present document specifies the minimum requirements for GMDSS radiocommunication system using Digital 
Selective Calling (DSC) Class A, with the capability to operate on a SOLAS bridge with the application of SOLAS 
regulation V/15 [i.4] and thus implementing the BAM concept defined by IMO in MSC.302(87) [8]. 

The present document states minimum requirements for GMDSS radiocommunication equipment using Digital Selective 
Calling (DSC) Class A [2], with the capability to fully operate handling of the automated procedures defined in part 2 of this 
multi-part deliverable, see ETSI EN 300 338-2 [2] from a remote position such as a central HMI. 
In addition other proprietary control interfaces may apply to support full remote control of other DSC equipment functions. 
Such proprietary control interfaces (whether based on proprietary IEC 61162-1 [3] sentences or other protocols) are not part 
of the present document, and may co-exist with the requirements in the present document. 

The present document specifies requirements on the content of certificates issued to natural persons. This profile builds 
on IETF RFC 5280 [1] for generic profiling of Recommendation ITU-T X.509 | ISO/IEC 9594-8 [i.3]. 
This profile supports the requirements of EU Qualified Certificates as specified in the Regulation (EU) 
No 910/2014 [i.5] as well as other forms of certificate. The scope of the present document is primary limited to 
facilitate interoperable processing and display of certificate information. This profile therefore excludes support for 
some certificate information content options, which can be perfectly valid in a local context but which are not regarded 
as relevant or suitable for use in widely deployed applications. 
The present document focuses on requirements on certificate content. Requirements on decoding and processing rules 
are limited to aspects required to process certificate content defined in the present document. Further processing 
requirements are only specified for cases where it adds information that is necessary for the sake of interoperability. 
Certain applications or protocols impose specific requirements on certificate content. The present document is based on 
the assumption that these requirements are adequately defined by the respective application or protocol. It is therefore 
outside the scope of the present document to specify such application or protocol specific certificate content.
