The present document specifies accessibility and interoperability characteristics for the following types of products and services when used in emergency communications. They form together a chain of items involved in accessible emergency communications:
• Communication terminals used in electronic communications
• Electronic communication services
• Emergency communications systems including PSAPs
• Assisting services used in electronic communication services (relay services, language translation services, expert services)
The present document addresses technical aspects of interoperability between user equipment, originating services and emergency communications systems, and the interoperability and functionality required to be able to route emergency communications to the most appropriate PSAP and include assisting services when required. It specifies interoperable and accessible emergency communications, which incorporates voice, video, and real-time text.
Focus is on SIP and IMS technologies for user equipment and originating services, and SIP technology for the emergency communications systems. Brief information is provided on how to arrange emergency communications access also for other technologies.
General accessibility requirements on emergency communications as well as everyday communications including media performance aspects, functional details of the accessible media and general user interface requirements for accessibility are specified in EN 301 549.
NOTE: The relationship between the present document and essential requirements of Directive (EU) 2019/882, Annex I and Annex V is given in Annex AA and Annex AB.
