MANUAL OF TECHNICAL PROVISIONS FOR THE …

1 Dot 9705AN/956 MANUAL OF TECHNICAL PROVISIONSFOR THE AERONAUTICALTELECOMMUNICATION network (ATN)SECOND EDITION - 1999 Approved by the Secretary Generaland published under his authorityINTERNATIONAL CIVIL AVIATION ORGANIZATION(iii)FOREWORDThe material contained in this document was originally developed as the detailed part of thefirst set of Standards and Recommended Practices (SARPs) for the aeronautical telecommunication network (ATN) which has commonly been referred to as the CNS/ATM-1 Package. It was intended to make thematerial an appendix to the new Chapter 3 of Annex 10, Volume III, Part I, containing broad, general, stableand mostly regulatory-type PROVISIONS (the core part of new ATN SARPs).

2 In December 1997, the Air Navigation Commission (ANC), while conducting the finalreview of draft ATN SARPs, noted that actual implementation and operational experience was yet to begained by the international civil aviation community. In this regard, the ANC agreed that the detailed partof ATN SARPs should be published as an ICAO MANUAL (to be updated annually, if necessary), whileretaining its SARPs-style language. The ANC will review the status of the document, in its entirety or inparts, after sufficient implementation and operational experience has been gained and the requirements forfurther standardization, in the interests of safety, regularity and efficiency of international civil aviation havebeen better document consists of five Sub-Volumes.

8 The aeronautical telecommunication network (ATN) comprises application entities andcommunication services which allow ground, air-to-ground and avionics data subnetworks to interoperateby adopting common interface services and protocols based on the International Organization forStandardization (ISO) open systems interconnection (OSI) reference 2. This document addresses the following ATN TECHNICAL requirements:a)General and system level requirements;b)ATN application entity requirements;1)System application entity requirements;i)Context management (CM) application;2)Air-ground application entity requirements;i)Controller pilot data link communication (CPDLC) application;ii)Automatic dependent surveillance (ADS) application;iii)Flight information service (FIS) applications;3)Ground-ground application entity requirements;i)Air traffic services (ATS) inter-centre communication (ICC)applications.

An overview of this document is depicted in Figure of TECHNICAL PROVISIONS for the aeronautical telecommunication network (ATN)Figure Overview of documentWhen the following terms are used in this document, they have the following meanings:Abstract service interface. The abstract interface between the application entity (AE) and the syntax notation One ( ). Abstract syntax notation One is defined in ISO/IEC 8824-1.

10 Thepurpose of this notation is to enable data types to be defined, and values of those types specified, withoutdetermining their actual representation (encoding) for transfer by protocols. Addressing plan. A plan that provides common address syntax and management of global addresses for theunambiguous identification of all end and intermediate systems in accordance with the rules prescribedin ISO/IEC 7498-3 and ISO/IEC TR domain. A collection of end systems, intermediate systems and subnetworks operated by asingle organization or administrative authority. An administrative domain may be internally divided intoone or more routing The symbol used to designate automatic dependent application.
