ESSIP OUTLINE DESCRIPTION FOR THE IMPLEMENTATION OF THE VOICE OVER INTERNET PROTOCOL IN ATM DEFINITION & CONTEXT Topic Description Associated supporting material finalised? What is it? What has to be done? Why implement it? Why through ESSIP/LSSIP? Legal basis & SES / SESAR relationships WHAT Within pre-swim evolutions and preparation of SWIM implementation, the purpose of this ESSIP implementation initiative is to ensure that all ECAC States implement Air Traffic Management Voice Over Internet Protocol (ATM- VoIP), which provides the appropriate signalisation required for ATM voice communication. The initiative covers inter centre (encompassing all type of ATM Units) voice communication and the links with the ground radio stations Furthermore, the availability of VoIP for ATM ensures operational continuity for voice communications, considering that telecommunication operators will terminate the leasing of analogue circuits while increasing their lowest digital circuit to 2MB/s in the near future. The ANSPs will have to migrate to VoIP: Intercentre (all type of ATS units) telephony; Voice Communications Systems (VCS) links to the ground radio stations. WHY Inter centres voice communications are currently mainly performed via analogue circuits. In 2003, to implement digital communications, the ATS-QSIG protocol has been chosen to replace part of these communications (cf COM06). At present and in order to follow the evolution of the communication technologies, VoIP has been identified as being the medium term standard for voice G/G communications. Industry has already developed a standard for ATM-VoIP. The standard has still to be validated, but several ANSPs have expressed their wish to migrate quickly to ATS-VoIP for G/G voice communications, including the links to the ground radio stations. Furthermore, a number of Telecommunication Service Providers (TELCO s) are planning to phase out analogue and digital 64k circuits which support current ATM voice services (ATS-R2 and ATS-QSIG) There is a need at European level to coordinate and monitor the implementation of VoIP in ATM. ESSIP/LSSIP is the appropriate tool to do it in the ECAC area. 1) There is no specific EC Interoperability Rule or Community Specification developed yet in relation to the EC Interoperability Regulation 552-2004. 2) The initiative covers ICAO Global Plan Initiative GP-22 and SESAR enablers CTE-C8 Voice for ground telephony and CTE-C9 VoIP for ground segment of Air-Ground voice. 3) The initiative supports the following SESAR Operational Improvements: IS-0702 SWIM - European Ground Communication Infrastructure; CM-0102 Automated Support for Dynamic Sectorisation and Dynamic Constraint Management 4) Further SESAR references: SESAR D6 DLT-0710-432 task CNS-C09 Future Radio System Part / VoIP A/G delay. Strategic Guidance in Support of the European ATM Master Plan (Ed. 1.0 of May 2009), Annex C and D. COMT-43 held in Oct 2008 requested the Agency to prepare an ESSIP outline description focussed on VOIP (COMT action 43-07).

The associated supporting material should be the latest available version of the Project Management Plan (or equivalent common planning document). The scope relates to the types of operations, airspace, ATC units or geographical area within which the future objective is likely to deliver significant benefits. It is stipulated as follows: a) ECAC for all ECAC States; b) EU+ for all EU Member States + all European States having signed the European common aviation area agreement with the EU; c) OTHER when the community for applicability is specific and different from one of the first two. In this case, please specify the geographical area. Indicate stakeholders who will have to perform the implementation actions described. The categories used in this field are derived from the EATM Stakeholder Segmentation Model (Airspace users, Air Navigation Service Providers, Airport operators, National Regulatory Authorities, International organisations, Agency, Aeronautics industry), except that Military Authorities are shown a separate stakeholder category. Documentation such as concept of operations, validation trial and simulation reports, strategy, specification, standard, guidelines, operations or flight manuals, etc, other than those already specified as supporting material to performance benefit and timescale entries, the availability of which is required before concerned stakeholders start implementation. In principle, an implementation initiative is technically mature only once all identified prerequisites to the implementation by the stakeholders have been delivered and approved by the relevant specialist groups. Short statement summarising the discussions on the subject, to progress towards the description of an ESSIP objective. In principle, an implementation initiative is formally mature only once required ESSIP/LSSIP governance levels currently the specialist groups (Teams or PSGs) and the SCG have accepted the description of a draft implementation objective to be submitted to the SCG before endorsement by the PC.

Extract of the Strategic Guidance in Support of the Execution of the European ATM Master Plan - Annex D (ATM Infrastructure) - Ed.1.0 of May 2009 Capability Level 1 (before 2013) Section D3.2.3: En-route and TMA systems / Communications Ground voice communication services which use analogue signalling protocols will progressively evolve towards digital interfaces. This transition is driven by the communications industry where support for the analogue systems is diminishing rapidly. Capability Levels 2 and 3 (2013 2021) Section D3.3.3: En-route and TMA systems / Communications Operational use of VoIP for ground/ground voice communications will be gradually extended replacing the previous protocols (MFCR/2 and ATS QSIG). VoIP will also be implemented for the ground segment of the air ground voice link. Operational use of VOIP for the ground segment of the A/G voice communications will be provided for Capability level 2. Capability Levels 4 and 5 (after 2021) Section D3.4.3: En-route and TMA systems / Communications For ground-ground voice communications, VoIP is used in the whole of ECAC, completely replacing the current protocols (MFCR/2 and ATS QSIG) (with the possible exception of facilities at the ECAC borders).
