26、 1 Introduction This International Standard is one of a series of Standards defining services and signalling protocols applicable to Private Integrated Services Networks (PISNs). The series uses ISDN concepts as developed by CCITT and conforms to the framework of Standards for Open Systems Interconn

27、ection as defined by ISO. This particular International Standard specifies the signalling protocol for use at the Q reference point in support of the Route Restriction Class additional network feature. 1 Scope This International Standard specifies the signalling protocol for the support of the Route

28、 Restriction Class (RRC) additional network feature (ANF-RRC) at the Q reference point between Private Integrated Services Network Exchanges (PINXs) connected together within a Private Integrated Services Network (PISN). ANF-RRC is a feature which applies in the establishment phase of a call, allowi

29、ng that call to access facilities that are within an allowable restriction range. The Q reference point is defined in ISO/IEC11579-1. Service specifications are produced in three stages and according to the method specified in CCITT Recommendation I.130. This International Standard contains the stag

30、e3 specification for the Q reference point and satisfies the requirements identified by the stage1 and stage2 specifications in ISO/IEC13242. The signalling protocol for ANF-RRC operates on top of the signalling protocol for basic circuit switched call control, as specified in ISO/IEC11572, and uses

31、 certain aspects of the generic procedures for the control of supplementary services specified in ISO/IEC11582. This International Standard also specifies additional signalling protocol requirements for the support of interactions at the Q reference point between ANF-RRC and other supplementary serv

32、ices 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 Conformance Statement (PICS) proforma in Annex A.
