Brief History This Standard is one of a series of ECMA Standards defining services and signalling protocols applicable to Private Integrated Services Networks (PI

4、SNs). 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 particular Standard specifies the signalling protocol for use at the Q reference point in support of the Call Identification

5、 and Call Linkage Additional Network Feature. The protocol defined in this Standard forms part of the PSS1 protocol (informally known as QSIG). This Standard is based upon the practical experience of ECMA member companies and the results of their active and continuous participation in the work of IS

6、O/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 Standard ECMA-314 (published by ECMA in September 2000), this 2nd Edition incorporates migration to ASN.1 version 1997 as well as

7、changes in order to achieve complete alignment with International Standard ISO/IEC 13870:2001(E) published by ISO/IEC in 2001. Adopted as 2nd Edition of Standard ECMA-314 by the General Assembly of December 2001. - i - Table of contents 1 Scope 1 2 Conformance 1 3 References (normative) 1 4 Definiti

X.208 / X.209 49 1 Scope This Standard specifies the signalling protocol for the support of the Call Identification and Call Linkage additional network feature (ANF-CIDL) at the Q reference point between Private Integ

18、rated Network services eXchanges (PINXs) connected together within a Private Integrated Services Network (PISN). ANF-CIDL is an additional network feature which allows the assignment of a Global Call Identification (GID) to identify a call end-to-end over the call route (i.e. between the two end PIN

19、Xs). As an option, a Thread Identification (TID) may be assigned to different calls which are logically linked together due to the operation of other supplementary services and/or ANFs. Additionally a Leg Identification (LID) may be assigned, to identify the different legs of a call. NOTE 1 This ANF

20、 has been developed to support the use of CSTA (ECMA-269) in a networked environment, i.e. in a PISN. Use of this ANF for other applications is not precluded. The Q reference point is defined in ECMA-133. Supplementary Service specifications are produced in three stages and according to the method s

21、pecified 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-313. The signalling protocol for ANF-CIDL operates on top of the signalling protocol for basic circuit switc

22、hed 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 interactions at the Q reference point between Ca

23、ll Identification and Call Linkage and other supplementary services and ANFs. This Standard is applicable to PINXs which can be interconnected to form a PISN. 2 Conformance In order to conform to this Standard, a PINX shall satisfy the requirements identified in the Protocol Implementation Conforman

24、ce Statement (PICS) proforma in annex A. Conformance to this Standard includes conforming to those clauses that specify protocol interactions between ANF-CIDL and other supplementary services and ANFs for which signalling protocols at the Q reference point are supported in accordance with the stage

25、3 standards concerned. 3 References (normative) The following standards contain provisions which, through reference in this text, constitute provisions of this Standard.
