Information technology — Telecommunications and information exchange between systems — Private integrated services network — Part 1: Reference configuration for PISN Exchanges (PINX)

Specifies PINX reference configuration, reference points, use of the PINX reference configuration. The configuration specified is not intended to require any specific implementation of a PINX, but only to provide guidance for the specification of PINX capabilities. It is sufficient to support ISDN-like applications and can be extended to also support non-ISDN-like application. It describes a conceptual PINX. By combining multiple PINXs to a private integrated services network it becomes applicable to a PISN.

Foreword
ISQ (the International Organization for Standardization) and IEC (the International
Electrotechnical Commission) form the specialized System for worldwide stan-
dardization. National bodies that are members of ISO or IEC participate in the
development of International Standards through technical committees established
by the respective organization to deal with particular fields of technical activity.
ISO and IEC technical committees collaborate in fields of mutual interest. Other
international organizations, governmental and non-governmental, in liaison with
ISO and IEC, also take part in the work.
In the field of information technology, ISO and IEC have established a joint tech-
nical committee, ISO/IEC JTC 1. Draft International Standards adopted ’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 ISO/IEC 115794 was prepared by Joint Technical
Committee lSO/IEC JTC 1, Information technology, Subcommittee SC 6, Tele-
communications and information exchange between Systems.
ISO/IEC 11579 consists of the following Parts, under the general title Information
technology - Telecommunications and information exchange between
Systems - Private integrated Services networ.
- Part 1: ßeference configuration for PISN Exchanges (PINX)
- Parl2: ßeference configuration for High-Speed PISN Exchanges (HS-PINX)

ISOAEC 11579-1 :1994(E)
Introduction
The purpose of a reference config U ration (RC) is to reference Points means of identifying fu nctio nal g roupings which
bY
interwork at the reference Points.
Suitabl e defini tions of functional groupin gs allow the proper definition of the behaviour andlor Performance of such groupings,
merely by refe rring to the corresponding reference Points.
This applies to aspects such as:
- delimitation of areas of responsibility, e.g. for management, Operation etc.;
- partitioning and apportioning of Performance values;
- numbering;
- termination of signalling protocols;
- etc.
ISO/IEC 11579 will consist of several Parts. This patt of ISO/IEC 11579 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. lt also forms a component for a RC for high-Speed-PISNs (HS-PISN), i.e. PISNs 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 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 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 tan be of any nature from, in the trivial case, a mere physical 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 in an Overlay Scenario.
For further information on the Concatenation and the Overlay Seenarios see annex B.
In general, inter-PISN-exchange calls require that any two interconnected PISN exchanges
- tan be provided with bearer capabilities between each other, which support and satisfy the requirements as requested by
the users of the PISN; and
- tan interchange control information, which allows mutual control of network layer connections,
including the control of
supplementary Services, if applicable; and
- tan i nterchange ma .nagement information, enabling management actions
with regard to, e.g., the use and supervision of
the u ser 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
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.
