General

The present document specifies general policy requirements relating to Trust Service Providers (TSPs) that are 
independent of the type of TSP. It defines policy requirements on the operation and management practices of TSPs. 
Other specifications refine and extend these requirements as applicable to particular forms of TSP. The present 
document does not specify how the requirements identified can be assessed by an independent party, including 
requirements for information to be made available to such independent assessors, or requirements on such assessors. 
The present document aims to support the requirements on NIS2 Directive [i.13] and addresses the general requirements 
for security management and cybersecurity of trust services (qualified and non-qualified). 
NOTE: See ETSI EN 319 403-1 [i.2] for details about requirements for conformity assessment bodies assessing 
Trust Service Providers. 

The present document specifies technical requirements, limits, and test methods for radiodetermination equipment for 
location tracking applications operating in the frequency range 2,4 GHz to 2,4835 GHz. 
Further details of the covered equipment can be found in clause 4.2 of the present document. 
NOTE: The relationship between the present document and essential requirements of article 3.2 of 
Directive 2014/53/EU [i.3] is given in annex A

The present document concerns the assessment of Citizens' Band (CB) radio equipment intended for the transmission of 
speech and associated support equipment with regard to ElectroMagnetic Compatibility (EMC). 
Requirements relating to the antenna port and emissions from the housing port of CB radio equipment are not included 
in the present document. Such requirements can be found in the relevant product standards for the effective use of the 
radio spectrum, see Table 1.

Technology ETSI Standard
Angle-modulated Citizen's Band (CB) radio equipment and associated ancillary 
equipment operating in the frequency range 26 MHz to 28 MHz. ETSI EN 300 433 [i.3] 
Double Side Band (DSB) and/or Single Side Band (SSB) modulated CB radio 
equipment operating in the frequency range 26 MHz to 28 MHz ETSI EN 300 433 [i.3] 

NOTE: The relationship between the present document and the essential requirements of article 3.1(b) of 
Directive 2014/53/EU [i.4] is given in annex A.

I.S. 6:202X specifies respectively complementary requirements to those in I.S. EN 1916:2002 and its
corrigenda in I.S. EN 1916:2002/AC:2008 (“I.S. EN 1916:2002, as corrected”) for unreinforced and
reinforced concrete pipes and fittings with nominal sizes up to and including DN 1 750. Requirements
are also specified for unreinforced and reinforced pipes greater than DN 1 750, up to and including DN
3 000.

The present document describes the high-level System Architecture for the Future Railway Mobile Communications 
System (FRMCS). The interaction between FRMCS domains, high-level procedures, deployment scenarios and IP 
addressing/routing are also outlined. 

The present document specifies the FRMCS Transport Stratum for the Future Railway Mobile Communications System 
(FRMCS). In general, the FRMCS Transport Stratum provides data connectivity and the related services. 
The present document covers: 
• 3GPP terrestrial access. 
• Transport stratum interconnection scenarios in all aspects. 
• 3GPP access sharing, mobility within transport stratum. 
• QoS and policy control. 
• Authentication and authorization for the use of the transport stratum. 
• Transport stratum common features. 

The present document defines the Service Stratum for the Future Railway Mobile Communications System (FRMCS). 
In general, the FRMCS Service Stratum provides communication service and corresponding complementary service 
resulting from 3GPP Mission Critical Services (MCX) and 3GPP multimedia system. 
While FRMCS is defined in various FRMCS ETSI Technical Specifications, the present document determines 
necessary components of the FRMCS Service Stratum, encompassing: 
• Building blocks and corresponding reference points of 3GPP MCX/IMS. 
• Reference points between MC systems/IMS for interconnection and unilateral use by MC organizations 
(MC migration). 
• Reference points between the MC system/IMS and external systems. 
• QoS and priority management. 
• User identification, authentication and authorization for the use of the FRMCS service stratum. 
• Communication security aspects. 
• Complementary and auxiliary service, e.g. alternative user addressing schemes. 

The present document specifies the interfaces of the On-Board FRMCS enabling either interaction with On-Board 
applications or with FRMCS entities outside the train. The present document also specifies the On-Board Multipath 
Function and a set of procedures the On-Board FRMCS will need to conform to.
