This document is identical to ISO/IEC 11579-l-1994 and the following five paragraphs are the original fore- word as it appeared in that document.) IS0 (the International Organization for Standardization) and IEC (the Intern

19、ational Electrotechnical Commission) form the specialized system for worldwide standardization. National bodies that are members of IS0 or IEC participate in the development of International Standards through technical committees established by the respective organization to deal with particular fie

20、lds of technical activity. IS0 and IEC technical committees collaborate in fields of mutual interest. Other international organizations, governmental and non-governmental, in liaison with IS0 and IEC, also take part in the work. In the field of information technology, IS0 and IEC have established a

21、joint technical committee, ISO/IEC JTC 1. Draft International Standards adopt- ed 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. International Standard IS

22、O/IEC 11579-l was prepared by Joint Technical Committee ISO/IEC JTC 1, Information technology, Subcommittee SC 6, Telecommunications and information exchange between systems.

This part of ISOllEC 11579 defines the RC for a 64 kbit/s-based Private Integrated Services Network (PISN) exchange (PINX), including a description for m

29、odelling complete PlSNs consisting of more than one PINX. It also forms a component for a RC for high-speed-PISNs (HS-PISN), i.e. PlSNs which may be based on technologies such as broad-band ISDN, LAN, etc. The particularities for HS-PISN will be specified in other parts of this standard. In addition

30、 to the user-to-ISDN reference configuration specified in CCITT Rec. 1.411 l which allows the exchanges of a private integrated services network (PISN) to interwork with a public ISDN in a Concatenation Scenario, ISO/IEC 11579 specifies a reference configuration which allows to specify the functions

31、 which apply to the control of connections and calls between any two exchanges of a given PISN The concept of this standard is based on the assumption that such inter-PISN-exchange connections are routed through an intervening network, which can be of any nature from, in the trivial case, a mere phy

32、sical medium like a piece of wire, up to a switching network, such as the public ISDN, provided it offers the required capabilities for carrying user and control information between the PISN exchanges. In the case that the IVN is represented by a public ISDN, the PISN and the public ISDN interwork i

33、n 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 interconnected PISN exchanges - can be provided with bearer capabilities between each other, which support and satisfy the requirement

34、s as requested by the users of the PISN; and - can interchange control information, which allows mutual control of network layer connections, including the control of supplementary services, if applicable; and - can interchange management information, enabling management actions with regard to, e.g.

35、, the use and supervision 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 connection control information between PISN exchanges shall be specified. Reference point C has been defined as an interface point

36、 where the access parameters and procedures and, if applicable, the control information between the PISN exchanges and the intervening network shall be specified. Annex A shows the various information flows terminating at the reference points specified in this part of ISO/IEC 11579. vi Copyright Ame

38、n Exchange Between Systems - Private Integrated Services Network - Part 1: Reference Configuration for PISN Exchanges (PINX) 1 Scope This part of ISO/IEC 11579 specifies a reference configura- tion (RC) for private integrated services network exchanges (PINX) for their interconnection to form privat

39、e integrated services networks (PISN). The configuration is not intended to require any specific implementation of a PINX, but only to provide guidance for the specification of PINX capabilities. This RC is sufficient to support ISDN-like applications. It can be extended to also support non-ISDN-lik

40、e applica- tions. This RC describes a conceptual PINX. By combining mul- tiple PlNXs to a private integrated services network the RC becomes applicable to a PISN. 2 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this pa

41、rt of ISO/IEC 11579. At the time of publication, the editions in- dicated are valid. All standards are subject to revision, and parties to agreements based on this part of ISO/IEC 11579 are encouraged to investigate the possibility of applying the most recent editions of the standards listed below.

45、O/IEC 11579, the follow- ing definitions apply: 4.1 reference configuration : A conceptual configuration showing functional arrangements within a public ISDN, a PISN or between a public ISDN and a PISN. Reference configurations are based on association rules of functional groupings and reference poi

46、nts. A functional arrangement may, but need not, be equivalent to a physical arrange- ments of units of equipment. 4.2 functional grouping : A set of functions needed in functional arrangements. A functional grouping may, but need not, be equivalent to a unit of equipment. Depending on the actual im

47、plementation, some of the functions of a functional grouping may or may not be present. 4.3 reference point (RP) : A conceptual point at the junction of two functional groupings. In a specific functional arrangement, a reference point may, but need not, corre- spond to a physical interface between u

48、nits of equipment. 4.4 private integrated services network (PISN) : A pri- vate network providing services to a specific set of users (different from a public network which provides services to the general public). 1 Copyright American National Standards Institute Provided by IHS under license with
