42、tal Network (ISDN) User Part (ISUP) version 2 (as specified in ETS 300 356-1 i211 and the Signalling Systems No.5 (as specified in CCITT Recommendations 0. 140 to 0. 164 i71), R2 (as specified in CCITT Recommendations 0.400 to 0.490 i811, Telephone User Part (TUP) (as specified in CCITT Recommendati

43、ons 0.721 to 0.725 i171). and TUP+ (as specified in CEPT Recommendation T/S 43-02 E i1 81). ISUP version 2 (as specified in ETS 300 356-1 i211 has been designed to allow peer-to-peer operation to a version 1 exchange (as specified in ETC 300 121 ill) without requiring any knowledge of that situation

44、. This means that different ISUP versions (like version 1 and version 2) cannot be considered as different signalling systems in an exchange. A specific interworking specification is not required, relevant information is contained in ETS 300 356-1 i21. This specification is applicable to internation

45、al transit exchanges, but may be used as a basis for the interworking in international gateway exchanges, because ISUP at the national side may also be based on ISUP version 2. 2 Normative references This ETS incorporates by dated and undated reference, provisions from other publications.
