3、NX).Brief HistoryThe purpose of a reference configuration (RC) is to define reference points by means of identifying functionalgroupings which interwork at the reference points.Suitable definitions of functional groupings allow the proper definition of the behaviour and/or performance of suchgroupin
4、gs, merely by referring to the corresponding reference points.This applies to aspects such as:G01 delimitation of areas of responsibility, e.g. for management, operation etc.;G01 partitioning and apportioning of performance values;G01 numbering;G01 termination of signalling protocols;G01 etc.This pa
5、rticular Standard defines the RC for a 64 kbit/s-based Private Integrated Services Network (PISN) exchange(PINX), including a description for modelling complete PISNs consisting of more than one PINX. It also forms acomponent for a RC for high-speed-PISNs (HS-PISN), i.e. PISNs which may be based on
6、technologies such asbroad-band ISDN, LAN, etc. The particularities for HS-PISN will be specified in other parts of this Standard.In addition to the user-to-ISDN reference configuration specified in ITU-T Rec. I.411 which allows the exchanges ofa private integrated services network (PISN) to interwor
7、k with a public ISDN in a Concatenation Scenario,ISO/IEC 11579 specifies a reference configuration which allows to specify the functions which apply to the controlof connections and calls between any two exchanges of a given PISN.The concept of this Standard is based on the assumption that such inte
8、r-PISN-exchange connections are routedthrough an intervening network, which can be of any nature from, in the trivial case, a mere physical medium like apiece of wire, up to a switching network, such as the public ISDN, provided it offers the required capabilities forcarrying user and control inform
9、ation between the PISN exchanges. In the case that the IVN is represented by apublic ISDN, the PISN and the public ISDN interwork in an Overlay Scenario.For further information on the Concatenation and the Overlay Scenarios see annex B.In general, inter-PISN-exchange calls require that any two inter
10、connected PISN exchangesG01 can be provided with bearer capabilities between each other, which support and satisfy the requirements asrequested by the users of the PISN; andG01 can interchange control information, which allows mutual control of network layer connections, including thecontrol of supp
11、lementary services, if applicable; andG01 can interchange management information, enabling management actions with regard to, e.g., the use andsupervision of the user information channels.Reference point Q has been defined as a conceptual point (e.g. not as a real interface) where the exchange of co
12、n-nection control information between PISN exchanges shall be specified. Reference point C has been defined as aninterface point where the access parameters and procedures and, if applicable, the control information between thePISN exchanges and the intervening network shall be specified.Annex A sho
