Integrated Services Digital Network (ISDN); Signalling System No.7 (SS7); ISDN User Part (ISUP) version 4 for the international interface; Part 22: International Emergency Preference Scheme (IEPS) service [ITU-T Amendments (2002) to Q.761 - Q.764 (1999) modified]

This document defines an enhancement of the ISUP protocol, the latter contained in ETS 300 356. The objective is to allow a prioritized call setup in case of an emergency situation, facilitating the organization of relief action. It focuses on marking the calls of emergency relief personnel in the international signalling network. Thus, the document provides a solution for supporting IEPS according to E.106 on the international connection section. Cooperation with SPAN 14 takes place , where appropriate. Work in ITU-T SG 11 will be observed.

Global modifications to ITU-T Amendments to Q.761 - Q.764 Insert the following two clauses (Scope and References). Scope The present document 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 protocol 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 signalling interface. NOTE 1: 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. Although the present document applies only to the international interconnection, the specification of functions, formats and codes of messages and signals, and actions performed at originating and destination local exchanges are retained. Formats, codes and procedures marked for national use are included for informative purposes for the international interface specification. If these items so marked are supported within a national network and operator's network, then it is proposed that they shall be supported in this manner. NOTE 2: In the case where a national signalling system behaves differently, the international gateway exchange is to support both the concerned national and international network. 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.

Specific modifications to ITU-T Amendments to Q.761 - Q.764 (12/99) Amendment 2 to ITU-T Recommendation Q.761 is endorsed without any modifications. Amendment 1 to ITU-T Recommendation Q.762 is endorsed without any modifications. Amendment 2 to ITU-T Recommendation Q.763 is endorsed without any modifications. Amendment 2 to ITU-T Recommendation Q.764 is endorsed with the following modifications. In all chapters on Actions required at an outgoing, intermediate or incoming international exchange • in the first sentence the phrase "call establishment proceeds with priority" is improved to read "call and connection establishment proceeds with priority"; • in the second paragraph the phrase "the call is queued and shall take precedence over any other normal call attempts" is replaced by "then the call is placed at the top of the call handling queue in the exchange. The priority calls queued shall take priority over any other call handling for the next free trunk from that exchange. For that purpose the exchange continually tries to find a suitable outgoing trunk until call establishment is discontinued. The calls in the queue are handled in the order of "first come, first served". The size of the queue is configurable according to traffic management"; • in the first sentence of the third paragraph the first word "Optionally" is deleted and the words "may be" are replaced by the word "is"; • the first sentence of the third paragraph is continued with the words "indicating that the call request has been put into a waiting queue for priority call setup"; • after the first sent
