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.

ISO/IEC 13868:2003(E)
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.

6.2 Information Elements
The operations defined in 6.1 for the support of SS-CNIP and SS-CONP shall be coded in the Facility information element in
accordance with ISO/IEC 11582.
When conveying the invoke APDU of the operations defined in 6.1, the destinationEntity data element of the NFE shall contain
value endPINX. The Interpretation APDU in the Facility information element shall be included and shall have the value
"discardAnyUnrecognisedInvokeAPDU (0)".
6.3 Messages
Basic call messages ALERTING, CONNECT, DISCONNECT, FACILITY, RELEASE, RELEASE COMPLETE, PROGRESS
and SETUP shall be used for conveying the Facility information element in support of SS-CNIP and SS-CONP as specified in
ISO/IEC 11582.
7 Signalling Protocol for the Support of SS-CNIP
7.1 SS-CNIP Description
Calling Name Identification Presentation (SS-CNIP) is a supplementary service which is offered to the called user and which
provides the name of the calling user to the called user.
The PISN provides the calling user's name and delivers the calling user's name to the called user whenever an incoming call is
presented.
The presentation of the calling user's name may be restricted as specified in SS-CNIR. Some users may have a service profile
which permits the override of calling name identification restriction.
This supplementary service is applicable to all basic services, defined in ISO/IEC 11574.

ISO/IEC 13868:2003(E)
7.2 SS-CNIP Operational Requirements
7.2.1 Requirements on the Originating PINX and the Incoming Gateway PINX
Call establishment procedures, as specified in ISO/IEC 11572, shall apply. Additionally, these PINXs shall be responsible for
obtaining the name information. An Originating PINX may limit, to less than 50, the number of characters that can be
registered against a user.
Generic procedures for the call related control of supplementary services, as specified in ISO/IEC 11582 for a Source PINX,
shall apply.
7.2.2 Requirements on the Terminating PINX and the Outgoing Gateway PINX
Call establishment procedures, as specified in ISO/IEC 11572, shall apply. Additionally, these PINXs shall be responsible for
delivering the name information to the user or to the other network.
Generic procedures for the call related control of supplementary services, as specified in ISO/IEC 11582 for a Destination
PINX, shall apply.

7.2.3 Requirements on a Transit PINX
Call establishment procedures, as specified in ISO/IEC 11572, shall apply.
Generic procedures for the call related control of supplementary services, as specified in ISO/IEC 11582 for a Transit PINX,
shall apply.
7.3 SS-CNIP State Definitions
No specific state definitions are required.
7.4 SS-CNIP Signalling Procedures for Invocation and Operation
7.4.1 Actions at the Originating PINX

7.4.1.1 Normal procedures
If the calling user's name is available and presentation is allowed, the callingName invoke APDU shall be sent in the SETUP
message from the Originating PINX to the Terminating PINX. Within the argument, the NamePresentationAllowed type shall
be chosen for the element of type Name.
If the calling user's name is available and presentation is restricted, the callingName invoke APDU shall also be sent in the
SETUP message from the Originating PINX to the Terminating PINX. Within the argument, the NamePresentationRestricted
type shall be chosen for the element of type Name.
If the calling user's name is not available, the callingName invoke APDU may be sent in the SETUP message from the
Originating PINX to the Terminating PINX. Within the argument, the NameNotAvailable type shall be chosen for the element
of type Name.
7.4.1.2 Exceptional procedures
Not applicable.
7.4.2 Actions at the Terminating PINX
7.4.2.1 Normal procedures
If the callingName invoke APDU has been received with an element of type NamePresentationAllowed in the argument, the
name information including the presentation indicator shall be delivered to the called user if able and authorized to receive the
calling name information
If the callingName invoke APDU has been received with an element of type NamePresentationRestricted in the argument, no
name information other than the presentation indictor shall be delivered to the called user, unless the called user has an override
capability.
If either the callingName invoke APDU has not been received or the callingName invoke APDU has been received with an
element of type NameNotAvailable in the argument, no name information other than the presentation indicator "name not
available" shall be delivered to the called user.
7.4.2.2 Exceptional procedures
Not applicable.

ISO/IEC 13868:2003(E)
7.4.3 Actions at a Transit PINX
No special actions are required in support of SS-CNIP.
7.5 SS-CNIP Impact of Interworking with Public ISDNs or with Non-ISDNs
7.5.1 Actions at the Incoming Gateway PINX
On calls incoming from another network, if the other network provides the calling user's name information, it shall be sent to
the Terminating PINX as specified in 7.4.1 (the Incoming Gateway PINX thereby acting as an Originating PINX). If the other
network does not provide the calling user name, but provide an indication that the calling user name is restricted, the incoming
gateway PINX shall include the callingName invoke APDU in the SETUP message sent to the Terminating PINX. Within the
argument, choice namePresentationRestrictedNull of type NamePresentationRestricted shall be chosen for the element of type
Name.
If the number of characters in the calling party name exceeds 50, the PINX shall truncate the excess characters.
A public network may send delayed calling user’s name information (e.g. in a FACILITY message subsequent to sending the
SETUP message when conforming to ANSI T1.641-1995). In this case, the Incoming Gateway PINX may include the name
information in a callingName invoke APDU in a FACILITY message and send it to the Terminating PINX, after the first
backwards end-to-end message (i.e. ALERTING, PROGRESS or CONNECT) has been received. As defined in 6.2, the
Interpretation APDU shall be included in the Facility information element in that FACILITY message and shall have the value

8 Signalling Protocol for the Support of SS-CONP
8.1 SS-CONP General Description
Connected Name identification Presentation (SS-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 that answers the call;
optionally the name of the alerting user;
optionally the name of the called user that cannot be reached.
The PISN provides the connected user's name and delivers the connected user's name to the calling user whenever an incoming
