12、4 All rights reservedForeword ISO (the International Organization for Standardization) and IEC (the International Electrotechnical Commission) form the specialized system for worldwide standardization. National bodies that are members of ISO or IEC participate in the development of International Sta

13、ndards through technical committees established by the respective organization to deal with particular fields of technical activity. ISO and IEC technical committees collaborate in fields of mutual interest. Other international organizations, governmental and non-governmental, in liaison with ISO an

14、d IEC, also take part in the work. In the field of information technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of the joint technical committee

15、 is to prepare International Standards. Draft International Standards adopted by the joint technical committee are circulated to national bodies for voting. Publication as an International Standard requires approval by at least 75 % of the national bodies casting a vote. Attention is drawn to the po

16、ssibility that some of the elements of this document may be the subject of patent rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights. ISO/IEC 20114 was prepared by ECMA (as ECMA-344) and was adopted, under a special “fast-track procedure”, by Joint Techni

17、cal Committee ISO/IEC JTC 1, Information technology, in parallel with its approval by national bodies of ISO and IEC. ISO/IEC 20114:2004(E) ISO/IEC 2004 All rights reserved vIntroduction This International Standard is one of a series defining services and signalling protocols applicable to Private I

18、ntegrated Services Networks (PISNs). The series uses ISDN concepts as developed by ITU-T and conforms to the framework of International Standards for Open Systems Interconnection as defined by ISO/IEC. This International Standard specifies the signalling protocol for use at the Q reference point in

19、support of the Make Call Request supplementary service. The protocol defined in this International Standard forms part of the PSS1 protocol (informally known as QSIG). This International Standard is based upon the practical experience of ECMA member companies and the results of their active and cont

20、inuous participation in the work of ISO/IEC JTC1, ITU-T, ETSI and other international and national standardization bodies. It represents a pragmatic and widely based consensus.

21、d information exchange between systems Private Integrated Services Network (PISN) Inter-exchange signalling protocol Make call request supplementary service 1 Scope This International Standard specifies the signalling protocol for the support of the Make Call Request supplementary service (SS-MCR) a

22、t the Q reference point between Private Integrated services Network eXchanges (PINXs) connected together within a Private Integrated Services Network (PISN). Supplementary service MCR enables a Requesting User to request a Co-operating User to establish a new Requested Call to a Destination User. Th

23、is new Requested Call between the Co-operating and Destination User can be either a Basic call or a Call Independent Signalling Connection. The Q reference point is defined in ISO/IEC 11579-1. Service specifications are produced in three stages and according to the method specified in ETS 300 387. T

24、his International Standard contains the stage 3 specification for the Q reference point and satisfies the requirements identified by the stage 1 and stage 2 specifications in ISO/IEC 20113. The signalling protocol for SS-MCR operates on top of the signalling protocol for basic circuit switched call

25、control, as specified in ISO/IEC 11572, and uses certain aspects of the generic procedures for the control of supplementary services specified in ISO/IEC 11582. This International Standard also specifies additional signalling protocol requirements for the support of interactions at the Q reference p

26、oint between SS-MCR and other supplementary services and ANFs. This International Standard is applicable to PINXs, which can interconnect to form a PISN. 2 Conformance In order to conform to this International Standard, a PINX shall satisfy the requirements identified in the Protocol Implementation

27、Conformance Statement (PICS) proforma in Annex A. Conformance to this International Standard includes conforming to those clauses that specify protocol interactions between SS-MCR and other supplementary services and ANFs for which signalling protocols at the Q reference point are supported in accor
