Foreword
This European Telecommunication Standard (ETS) has been produced by the European Computer Manufacturers
Association (ECMA) on behalf of its members and those of the European Telecommunications Standards Institute
(ETSI).
This ETS is one of a series of Standards defining supplementary services applicable to Private Telecommunication
Networks (PTNs) incorporating one or more interconnected exchanges. This particular ETS deals with the signalling
protocol for the support of Name Identification supplementary services. The Name Identification supplementary
services are Calling Name Identification Presentation (SS-CNIP) and Connected Name Identification Presentation (SS-
CONP).
This ETS was produced by ECMA using the ECMA guidelines for the production of ETSs and using the ECMA
stylesheet. In order to avoid undue delays in the publication of this ETS, it has been agreed that this ETS will not be
converted to the ETSI stylesheet.

1Scope
This Standard specifies the signalling protocol for the support of Name Identification supplementary services at
the Q reference point between Private Telecommunication Network Exchanges (PTNXs) connected together
within a Private Telecommunication Network (PTN). The Name Identification supplementary services are
Calling Name Identification Presentation (SS-CNIP) and Connected Name Identification Presentation (SS-
CONP).
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.
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 who answers the call,
− optionally the name of the alerting user,
− optionally the name of the called user who cannot be reached.
The supplementary service Calling/Connected Name Identification Restriction (SS-CNIR) has no impact on the
signalling at the Q reference point.
The Q reference point is defined in ENV 41004.
Service specifications are produced in three stages and according to the method specified in ENV 41005. This
Standard contains the stage 3 specification for the Q reference point and satisfies the requirements identified by
the stage 1 and 2 specifications in ETS 300 237.
NOTE 1
Signalling protocols for SS-CNIP and SS-CONP have the ability to convey an indication that presentation of a
name is restricted. The stage 1 and stage 2 specifications in ETS 300 237 for SS-CNIR do not place any
additional requirements on stage 3 at the Q reference point.
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 ETS 300 172, and uses certain aspects of the generic procedures for the
control of supplementary services specified in ETS 300 239.
The impact on the protocol of interactions between the supplementary services specified in this Standard and
other supplementary services is outside the scope of this Standard.
This Standard is applicable to PTNXs which can be interconnected to form a PTN.
2 Conformance
In order to conform to this Standard, a PTNX 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 ETS 300 239.
When conveying the invoke APDU of the operations defined in 6.1, the NFE in the Facility information
element shall be included and coded as defined in case no. 1 of 7.1.2.1 of ETS 300 239. The Interpretation
APDU in the Facility information element shall be included and shall have the value
"discardAnyUnrecognisedInvokePdu (0)".
6.3 Messages
Basic call messages ALERTING, CONNECT, DISCONNECT and SETUP shall be used for conveying the
Facility information element in support of SS-CNIP and SS-CONP as specified in ETS 300 239.
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 PTN 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 telecommunication services.
7.2 SS-CNIP Operational Requirements
7.2.1 Requirements on the Originating PTNX and the Incoming Gateway PTNX
Call establishment procedures, as specified in ETS 300 172, shall apply. Additionally, these PTNXs shall
be responsible for obtaining the name information.
Generic procedures for the call related control of supplementary services, as specified in ETS 300 239 for
a Source PTNX, shall apply.
7.2.2 Requirements on the Terminating PTNX and the Outgoing Gateway PTNX
Call establishment procedures, as specified in ETS 300 172, shall apply. Additionally, these PTNXs 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 ETS 300 239 for
a Destination PTNX, shall apply.
7.2.3 Requirements on a Transit PTNX
Call establishment procedures, as specified in ETS 300 172, shall apply.
Generic procedures for the call related control of supplementary services, as specified in ETS 300 239 for
a Transit PTNX, 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 PTNX
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 PTNX to the Terminating PTNX. 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 PTNX to the Terminating PTNX. 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 PTNX to the Terminating PTNX. 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 PTNX
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 authorised 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.
7.4.3 Actions at a Transit PTNX
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 PTNX
On calls incoming from another network, if the other network provides the calling user's name
information, it shall be sent to the Terminating PTNX as specified in 7.4.1 (the Incoming Gateway PTNX
thereby acting as an Originating PTNX).
7.5.2 Actions at the Outgoing Gateway PTNX
On outgoing calls to another network, the PTN shall deliver the calling user's name information to the
other network as specified in 7.4.2 (the Outgoing Gateway PTNX thereby acting as a Terminating PTNX),
if the other network supports an equivalent supplementary service.
7.6 SS-CNIP Parameter Values
No specific timers are required.
