EN 300 172 V1.4.1 (1997-09)3ForewordThis European Standard (EN) was produced by ECMA on behalf of its members and those of the EuropeanTelecommunications Standards Institute (ETSI).The protocol defined in the present document is the basis for the QSIG protocol for signalling at the Q reference pointbetween Private Integrated services Network eXchanges (PINX). The QSIG protocol is known as "Private integratedSignalling System No. 1" (PSS1) in International Standards.Whilst this particular EN defines signalling for the support of circuit-mode bearer services, other ETSs specify otheraspects of the QSIG protocol, e.g. generic procedures for the support of supplementary services, and individualsupplementary services.The previous (third) edition of the present document endorsed (with modification) the first edition of ISO/IEC 11572,published in 1994. This edition endorses (with modification) the second edition of ISO/IEC 11572 and two amendmentsto that International Standard.National transposition datesDate of adoption of this EN: 5 September 1997Date of latest announcement of this EN (doa): 31 December 1997Date of latest publication of new National Standardor endorsement of this EN (dop/e): 30 June 1998Date of withdrawal of any conflicting National Standard (dow): 30 June 1998Endorsement noticeThe text of International Standard ISO/IEC 11572 second edition (1996), together with two amendments to that text(Amendment 1 (1996) and Amendment 2 (1996)) was approved by ETSI as an EN with agreed modifications as givenbelow.NOTE: New or modified text is indicated using sidebars. In addition, underlining and/or strike-out are used tohighlight detailed modifications where necessary.SIST EN 300 172 V1.4.1:2005



EN 300 172 V1.4.1 (1997-09)4Clause 1Replace the text of clause 1 by:The present document defines the Layer 3 protocol for signalling for the support of circuit-mode bearer services (usedeither on their own or in support of teleservices) at the Q reference point between Private Integrated services NetworkeXchanges (PINX) connected together within a Private Integrated Services Network (PISN). The Q reference point isdefined in ETS 300 475-1 [16].Service specifications are produced in three stages and according to the method specified in ETS 300 387 [12]. Thedefinition of signalling protocols is stage 3 of the method. Stages 1 and 2 specifications of the basic circuit-mode bearerservices are to be found in ETS 300 171 [9]. The protocol defined in the present document satisfies the requirementsidentified by the stages 1 and 2 specifications in ETS 300 171 [9].Annex ZC is an integral part of the present document.Clause 2After clause 2, add the following new clause:2bis
ConformanceIn order to conform to the present document, a PINX shall satisfy the requirements identified in the ProtocolImplementation Conformance Statement (PICS) proforma in annex A.Clause 3Replace the first paragraph by:The present document incorporates by dated and undated reference, provisions from other publications. These normativereferences are cited at the appropriate places in the text and the publications are listed hereafter. For dated references,subsequent amendments to or revisions of any of these publications apply to the present document only whenincorporated in it by amendment or revision. For undated references the latest edition of the publication referred toapplies.Insert the following normative references at the end of clause 3:[9]
