3、1 22 849.60.01 - URL: http:/www.ecma.ch - Internet: helpdeskecma.ch IW Ecma-251.doc 14-01-02 10,15 . Brief History This Standard is one of a series of ECMA standards defining services and signalling protocols applicable to Private Integrated Services Networks. The series uses ISDN concepts as develo
4、ped by ITU-T and conforms to the framework of standards for Open Systems Interconnection as defined by ISO/IEC. This particular Standard specifies the signalling protocol for use at the Q reference point in support of the Common Information additional network feature. The Standard is based upon the
5、practical experience of ECMA member companies and the results of their active and continuous 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. Compared to the 1st Edition of Standa
6、rd ECMA-251 (published by ECMA in December 1996), the 2nd Edition incorporated changes to achieve complete alignment with International Standard ISO/IEC 15772:1998(E) published by ISO/IEC in November 1998. Compared to the 2nd Edition of Standard ECMA-251 (published by ECMA in December 1998), this 3r
7、d Edition incorporates migration to ASN.1 version 1997. Adopted as 3rd Edition of Standard ECMA-251 by the General Assembly of December 2001. - i - Table of contents 1 Scope 1 2 Conformance 1 3 References (normative) 1 4 Definitions 2 4.1 External definitions 2 5 List of acronyms 2 6 Signalling prot

17、ion additional network feature (ANF-CMN) at the Q reference point between Private Integrated services Network eXchanges (PINX) connected together within a Private Integrated Services Network (PISN). ANF-CMN is an additional network feature which enables the exchange of Common Information between ent
18、ities acting on behalf of the two ends of a connection through a PISN. This Common Information is a collection of miscellaneous information that relates to the user or equipment at one end of a connection and includes one or more of the following: Feature Identifiers, Party Category, Equipment Ident
19、ity. This information, when received by an entity, can be used for any purpose, e.g. as the basis for indications to the local user or to another network or in order to filter feature requests. The Q reference point is defined in ECMA-133. Additional network feature specifications are produced in th
20、ree stages and according to the method described in ETS 300 387. This 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 ECMA-250. The signalling protocol for ANF-CMN operates on top of the sign
21、alling protocol for basic circuit switched call control, as specified in ECMA-143, and uses certain aspects of the generic procedures for the control of supplementary services specified in ECMA-165. This Standard also specifies additional signalling protocol requirements for the support of interacti
22、ons at the Q reference point between ANF-CMN and other supplementary services and ANFs. NOTE 1 Additional interactions that have no impact on the signalling protocol at the Q reference point can be found in the relevant stage 1 specifications. This Standard is applicable to PINXs which can interconn
23、ect to form a PISN. 2 Conformance In order to conform to this Standard, a PINX shall satisfy the requirements identified in the Protocol Implementation Conformance Statement (PICS) proforma in annex A. Conformance to this Standard includes conforming to those clauses that specify protocol interactio
24、ns between ANF-CMN and other supplementary services and ANFs for which signalling protocols at the Q reference point are supported in accordance with the stage 3 standards concerned. 3 References (normative) The following standards contain provisions which, through reference in this text, constitute

37、ds of a connection through a PISN. This Common Information is a collection of miscellaneous information that relates to the user or equipment at one end of a connection and includes one or more of the following: Feature Identifiers, Party Category, Equipment Identity. This information, when received
38、 by an ANF-CMN user, can be used for any purpose, e.g. as the basis for indications to the local user or to another network or in order to filter feature requests. A solicited and an unsolicited service is offered to an ANF-CMN user. The solicited service enables the ANF-CMN user to request the Comm
39、on Information from a remote ANF-CMN user. The unsolicited service supplies the Common Information to an ANF-CMN user. These services may be combined and are not mutually exclusive. The Common Information contains the SS/ANF-identifiers supported by the ANF-CMN user and available for the particular
40、call, the possible options and - if applicable - details of the SS/ANF. Additionally, equipment identity and party category are contained. 6.2 ANF-CMN operational requirements 6.2.1 Requirements on an Originating PINX Call establishment procedures for the outgoing side of an inter-PINX link and call
