ISO/IEC 13868:2003

Information technology — Telecommunications and information exchange between systems — Private Integrated Services Network — Inter-exchange signalling protocol — Name identification supplementary services

ISO/IEC 13868:2003 specifies the signalling protocol for the support of name identification supplementary services at the Q reference point between Private Integrated services Network eXchanges (PINXs) connected together within a Private Integrated Services Network (PISN). The name identification supplementary services are Calling Name Identification Presentation (SS-CNIP) and Connected Name Identification Presentation (SS-CONP). Calling Name Identification Presentation (CNIP) is a supplementary service which is offered to the called user and which provides the name of the calling user (calling party name) to the called user. Connected Name Identification Presentation (CONP) is a supplementary service which is offered to the calling user and which provides to the calling user the following: the name of the user who answers the call (connected party name); optionally the name of the alerting user (called party name); optionally the name of the called user who cannot be reached (busy party name). The supplementary service Calling/Connected Name Identification Restriction (CNIR) has no impact on the signalling at Q reference point. Provision of a user's name to the PISN is outside the scope of ISO/IEC 13868:2003. The Q reference point is defined in ISO/IEC 11579-1. Service specifications are produced in three stages according to the method specified in ETS 300 387. ISO/IEC 13868:2003 contains the stage 3 specification for the Q reference point and satisfies the requirements identified by the stage 1 and stage 2 specifications in ISO/IEC 13864.

Foreword
ISO (the International Organization for Standardization) and IEC (the International Electrotechnical Commission) form the
specialized system for worldwide standardization. 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 technical committee, ISO/IEC JTC 1.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of the joint technical committee is to prepare International Standards. 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.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO and
IEC shall not be held responsible for identifying any or all such patent rights.
ISO/IEC 13868 was prepared by ECMA (as ECMA-164) and was adopted, under a special “fast-track procedure”, by Joint
Technical Committee ISO/IEC JTC 1, Information technology, in parallel with its approval by national bodies of ISO and IEC.
This second edition cancels and replaces the first edition (ISO/IEC 13868:1995), which has been technically revised.

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 ITU-T and conforms to the framework
of International Standards for Open Systems Interconnection as defined by ISO/IEC.
This International Standard specifies the signalling protocol for use at the Q reference point in support of the Calling Name
Identification Presentation (CNIP) and Connected Name Identification Presentation (CONP) supplementary services. The
protocol defined in this International Standard forms part of the PSS1 protocol (informally known as QSIG).
This International Standard is based upon the practical experience of ECMA member companies and the results of their active
and continuous participation in the work of ISO/IEC JTC 1, ITU-T, ETSI and other international and national standardization
bodies. It represents a pragmatic and widely based consensus.

INTERNATIONAL STANDARD ISO/IEC 13868:2003(E)

Information technology — Telecommunications and information
exchange between systems — Private Integrated Services Network —
Inter-exchange signalling protocol — Name identification supplementary
services
1Scope
This International Standard specifies the signalling protocol for the support of name identification supplementary services at the
Q reference point between Private Integrated services Network eXchanges (PINXs) connected together within a Private
Integrated Services Network (PISN). The name identification supplementary services are Calling Name Identification
Presentation (SS-CNIP) and Connected Name Identification Presentation (SS-CONP).
Calling Name Identification Presentation (CNIP) is a supplementary service which is offered to the called user and which
provides the name of the calling user (calling party name) to the called user.
Connected Name Identification Presentation (CONP) is a supplementary service which is offered to the calling user and which
provides to the calling user the following:
- the name of the user who answers the call (connected party name);
- optionally the name of the alerting user (called party name);
- optionally the name of the called user who cannot be reached (busy party name).
The supplementary service Calling/Connected Name Identification Restriction (CNIR) has no impact on the signalling at Q
reference point.
Provision of a user's name to the PISN is outside the scope of this International Standard.
The Q reference point is defined in ISO/IEC 11579-1.
Service specifications are produced in three stages according to the method specified in ETS 300 387. This International
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 ISO/IEC 13864.
The signalling protocol for SS-CNIP and SS-CONP operates on top of the signalling protocol for basic circuit switched call
control, as specified in ISO/IEC 11572, and uses certain aspects of the generic procedures for the control of supplementary
services specified in ISO/IEC 11582.
This International Standard also specifies additional signalling protocol requirements for the support of interactions at Q
reference point between name identification supplementary services and other supplementary services and ANFs.
This International Standard is applicable to PINXs which can be interconnected 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.
