Foreword
This European Telecommunication Standard (ETS) has been produced by the Signalling Protocols and
Switching (SPS) Technical Committee of the European Telecommunications Standards Institute (ETSI),
as working document T/S 43-03, and was adopted having passed through the ETSI standards approval
procedure.
This ETS is based on CCITT Recommendations Q.711 [1] to Q.714 [4] as recommended in the CCITT
Blue Book, 1988. The requirements of these CCITT Recommendations apply unless modified by the
exception statements contained in Clause 4 of this ETS. In addition, the standard includes the specific
requirements contained in Clause 5 of this ETS.
CCITT Recommendation Q.716 [5] shall also apply.
This ETS is also based on the following assumptions concerning the interconnection of national Signalling
Connection Control Parts (SCCPs):
- the Message Transfer Part (MTP) specified in ETS 300 008 [6] supports the SCCP for international
interconnection;
- at present, no SCCP users (subsystem) have been identified in the international network and,
therefore, no need exists for management messages to be originated or terminated. However,
Unitdata messages containing management information should be carried in the international
network as all other Unitdata messages.
- a global title including the country code, is required for routing in the international network. The
global title format of CCITT Recommendation Q.713 [3], § 3.4.2.3.4, is to be used (Global Title
Indicator = 0100).

1 Scope
The scope of this ETS is the further development of the CCITT Signalling System No. 7 protocols for both
the Integrated Services Digital Network (ISDN) and Public Switched Telephone Network (PSTN) following
the publication of CCITT Recommendations Q.711 [1] to Q.714 [4] and Q.716 [5].
