13、ed to support the International Emergency Preference Scheme (IEPS) service. The stage 1 aspects are detailed in ITU-T Recommendation E.106 1. The present document is an endorsement of an amendment of the ITU-T Recommendation and it also refers to ETS 300 121 which is an endorsement. National transpo

15、orsement notice The elements of ITU-T Recommendation Q.767 Amendment 1 apply with the following modifications. ETSI ETSI EN 300 121 V1.2.1 (2003-07) 4 Global modifications to ITU-T Amendment 1 to Recommendation Q.767 Insert the following two clauses (Scope and References). Scope The present document

16、 specifies the signalling protocol and switching aspects of the International Emergency Preference Scheme (IEPS) service for the pan-European Integrated Services Digital Network (ISDN) as provided by the European public telecommunications operators by means of the Signalling System No.7 (SS7) protoc

17、ol for the ISDN User Part (ISUP). The present document does not specify the additional protocol requirements where the service is provided to the user via a telecommunications network that is not an ISDN. The present document does not specify the additional protocol requirements for the national sig

18、nalling interface. NOTE: If the implementation of a signalling system in a national network conflicts with measures described here the international gateway of the network is expected to provide the interworking between the two. The present document applies only to the international interconnection.

19、 The IEPS service provides the calling party with preferential treatment during call and connection setup. The IEPS service is applicable to all international circuit switched telecommunication services. References The following documents contain provisions which, through reference in this text, con
