4、nces 16 The following standards contain provisions which, through reference in this text, 17 constitute provisions of this International Standard. At the time of publication, 18 the editions indicated were valid. All standards are subject to revision, and parties 19 to agreements based on this Inter
5、national Standard are encouraged to investigate 20 the possibility of applying the most recent editions of the standards indicated 1.1 Scope The interface is oriented towards the needs of gateways and applications that require full access to the features of the protocols. NOTE: There are industry-st
6、andard and proprietary AFIs that can be used by simple applications that only require the main features of the protocols. 21 1) The numbers in curly brackets correspond to those of the normative references in 1.2. 1.2 Normative References 1 22 Iso/IEC 14365:1996(E) OISO/IEC below.
