If these items so marked are supported within a national network and operator's network, then itis proposed that they shall be supported in this manner.Items in the present document marked "not required" are not required to be supported.NOTE:In the case where a national signalling system behaves differently, the international gateway exchange isto support both the concerned national and international network.The present document is compatible with ETS 300 121 [2] (CCITT Recommendation Q.767).Descriptions of interworking with CCITT Blue Book (1988) exchanges are informative only.ReferencesThe following documents contain provisions which, through reference in this text, constitute provisions of the presentdocument.· References are either specific (identified by date of publication, edition number, version number, etc.) ornon-specific.· For a specific reference, subsequent revisions do not apply.· For a non-specific reference, subsequent revisions do apply.· A non-specific reference to an ETS shall also be taken to refer to later versions published as an EN with the samenumber.[1]CCITT Recommendation E.164 (1997): "The international public telecommunication numberingplan; This Recommendation is also included but not published in I series under alias number I.331.Replaces former E.163 numbering plan".[2]ETS 300 121 (1992): "Integrated Services Digital Network (ISDN); Application of the ISDN UserPart (ISUP) of CCITT Signalling System No.7 for international ISDN interconnections (ISUPversion 1)".[3]EN 300 356-2: "Integrated Services Digital Network (ISDN); Signalling System No.7; ISDN UserPart (ISUP) version 3 for the international interface; Part 2: ISDN supplementary services[ITU-T Recommendation Q.730 (1997), modified]".SIST EN 300 356-1 V3.2.2:2003

This applies to the called party number, whether signalled by the en bloc or overlap methods, and all the othernumber types transferred by ISUP, e.g. Calling Party Number, etc.However, within national networks, it is acknowledged that the E.164 number length is too restrictive for someapplications, and specifically various national requirements for the extension of the called party number are known. Thefollowing remarks are made with regard to extension of number lengths for use within national networks:Interoperability problems can be foreseen with peer-to-peer interworking to earlier versions of ISUP, which may onlysupport the parameter lengths indicated in previous versions of ISUP.Gateway exchanges between networks using extended number lengths and the international network have to ensure thatonly E.164 number lengths are passed to the international network.Table 4/Q.763Modify table 4/Q.763 as shown in table 5.Table 5Message typeReference(table)CodeApplication transport22A01000001Pre-release information32A01000010Table 5/Q.763Modify table 5/Q.763 as shown in table 6.Table 6Parameter nameReference(subclause)CodeApplication transport3.8301111000Connection Request (not required)3.1700001101CCNR possible indicator3.82to be allocatedMLPP precedence (not required)3.3400111010Reserved for national use01000001Subclause 3.17Add "(not required)" to the subclause title.SIST EN 300 356-1 V3.2.2:2003
