EUROCAE ED-137/2C PDF

FOREWORD

This document “Interoperability Standards for VoIP ATM Components – Volume 2: Telephone” was prepared by EUROCAE Working Group 67 and was accepted by the Council of EUROCAE on 23 March 2019.

EUROCAE is an international non-profit making organisation. Membership is open to manufacturers and users in Europe of equipment for aeronautics, trade associations, national civil aviation administrations and non-European organisations. Its work programme is principally directed to the preparation of performance specifications and guidance documents for civil aviation equipment, for adoption and use at European and world-wide levels.

The findings of EUROCAE are resolved after discussion among its members and, where appropriate, in collaboration with RTCA Inc, Washington D.C. USA and/or the Society of Automotive Engineers (SAE), Warrendale, PA, USA through their appropriate committee.

ED-137C Volume 2 consists of the core document and a total of 8 Addenda containing the following information:

• ED-137/2C Add 1: Legacy Telephone Interworking ATS-R2, ATS-No.5 and ATS-QSIG

• ED-137/2C Add 2: FAA Legacy Telephone Interworking

• ED-137/2C Add 3: Instantaneous Access Call (replacing chapter 4.3 of ED- 137B Volume 2)

• ED-137/2C Add 4: Override Call

• ED-137/2C Add 5: Voice Call

• ED-137/2C Add 6: Extended Call Forward

• ED-137/2C Add 7: Hotline Access Call

• ED-137/2C Add 8: Radio Intercom Call

This version of the document represents “the minimum specification required for Manufacturers and Users to assure Interoperability between VoIP ATM Telephone Components”. EUROCAE WG67 has updated the previous version of ED137B and created ED 137 Volume 2 complemented by Addenda replacing ED137B Volume 2, referenced in ICAO document 9896:

• following a series of plug tests, performed by many suppliers in Arlington in May 2011 and in Sophia Antipolis in June 2011, improving ED-137 concerning the understanding of interoperability requirements between the ATM VoIP components,

• following discussions with FAA for taking into account US requirements agreeable within the European context,

• following the introduction of new features: Call/Answer Call, Call Pickup, Connected Identity, Group Member List, Loop Closure Detection, Echo Reduction, Basic Call Forward,Multi Destination Call

This version is taking into account the EUROCONTROL VoIP in ATM Test Case Specification
