Intellectual Property Rights
IPRs essential or potentially essential to the present document may have been declared to ETSI. The information
pertaining to these essential IPRs, if any, is publicly available for ETSI members and non-members, and can be found
in SR 000 314: "Intellectual Property Rights (IPRs); Essential, or potentially Essential, IPRs notified to ETSI in respect
of ETSI standards", which is available from the ETSI Secretariat. Latest updates are available on the ETSI Web server
(http://www.etsi.org/ipr).
Pursuant to the ETSI IPR Policy, no investigation, including IPR searches, has been carried out by ETSI. No guarantee
can be given as to the existence of other IPRs not referenced in SR 000 314 (or the updates on the ETSI Web server)
which are, or may be, or may become, essential to the present document.
Foreword
This Technical Report (TR) has been produced by ETSI Technical Committee Services and Protocols for Advanced
Networks (SPAN).
The present document describes the general requirements for presenting calling name information to users connected to
PSTN or ISDN. The ability of the calling party to restrict the presentation of its name is also covered.

1 Scope
The present document gives a set of requirements, observations and areas of further investigations to be used in order to
base further actions in ETSI, regarding services that deal with presenting and restricting calling name information to
users connected to PSTN or ISDN. The following supplementary services are within the scope of the present document:
- Calling Name Identification Presentation (CNIP) is a supplementary service which is offered to the called user
and which provides name information associated with the calling user (calling party name) to the called user;
- Calling Name Identification Restriction (CNIR) is a supplementary service which is offered to the calling user
to prevent presentation of the user's name information to the called user.
The identification of requirements is based on analysing existing or emerging European standards and international
recommendations on calling name information. Furthermore, due to the obvious clear analogy with CLI services,
European standards on CLI management for PSTN and ISDN users have been taken into account.
The CNIP and CNIR services on the PSTN and ISDN are offered in United States of America and Canada, where the
market is more developed especially in terms of residential phone services and business applications. These services are
considered enhanced CLI services. Within Europe some service providers are performing field trials.
The following aspects are excluded from the scope of the present document:
a) Interactions with supplementary services;
b) Quality of service;
c) Charging aspects.

4 Analysis of requirements
4.1 General issues
CNI is name information associated with a specific calling party number. The length, format and character set of the
CNI should be defined in order to meet the different characteristics of European names. A minimum length should be
agreed to facilitate interworking between networks. The provision of a new service that transmits names requires the
development or updating of terminals to be able to display the received characters set. In PSTN protocol over the local
loop (ETS 300 659-1 [1]) a name parameter coded in IA5 is specified.
Observation 1: Further investigation is required into the characteristics of the CNI and the impact on ISDN and
PSTN terminals.
Although one can imagine that most of the regulations applicable to a CLI number may be extended to a name service, it
is clear that a name service may need some more specific regulation. For example, ex-directory subscribers who do not
want the association between their number and their name to be published may request even stronger restrictions
concerning the delivery of their names than of their numbers, or they may agree to have their names transmitted but not
their numbers.
Observation 2: Different regulations are expected for calling name services (e.g. for ex-directory subscribers).
Depending on national regulations, some networks may define categories of subscriber that have the ability to override
the presentation restriction and have the CNI presented (e.g. the police). The ability to have such override category is a
national option.
Observation 3: The ability to have categories of user that have the possibility to override the presentation
restriction of CNI should be taken into account.
Both CNI and CLI may be delivered if the called user is subscribed to both CNIP and CLIP. Likewise, both CNI and
CLI may be treated as "private" or "public" for that particular incoming call taking into account the network stored
values associated with CLI and CNI of the calling user, or regardless the network stored values associated.
Observation 4: Allow the capability to provide both CNI and CLI, and if possible invoke restriction or release of
oneorbothwithasinglecommand.
Observation 5: Evaluate if the override category for CNIR could be related to the override category of CLIP.
