1 Scope
The present document specifies the Human Factors (HF) requirements related to all aspects of a European Telephony
Numbering Space (ETNS). It describes the requirements to be met jointly by the ETNS service provider and the
network operator enabling access to the ETNS service.
The present document applies to any ETNS service provided within an ETNS scheme based upon a European Country
Code (CC) and provided for access from public and private telecommunications networks.
It covers those aspects of ETNS services that would be of importance to the users of those services and to other
telephony users who may be affected by the introduction of an ETNS. Requirements cover:
- the formatting of the written presentation of ETNS numbers to enable users:
- to identify an ETNS service;
- to minimize dialling errors caused by difficulties in memorizing long digit strings;
- rules for migrating from an ETNS Service to a Global Service that will minimize difficulties for users;
- rules that ensure that called users receive appropriate Calling Line Identity (CLI) information when called from a
European Number (EN);
- rules that ensure calling users are still able to determine call charges after a EN has been ported to a new
provider;
- rules that ensure the minimization of user difficulties caused by call delays;
- rules to overcome the potential linguistic difficulties associated with ETNS services.
Mobility aspects of an ETNS are outside the scope of the present document. Only those aspects of an ETNS to which
specific requirements can be attached are covered in the present document. Other Human Factors aspects of an ETNS
are presented in TR 101 056 [1].

3 Definitions and abbreviations
3.1 Definitions
For the purposes of the present document, the following definitions apply:
post-dialling delay: for ISDN calls the post-dialling delay is the post-selection delay (en-bloc sending). For non-ISDN
calls the post-dialling delay is the time interval from the caller pressing the last dialled digit or pressing a key to send all
the digits of the called number until a call disposition message or signal is received by the calling terminal.
Post-Selection Delay (EN-Bloc Sending): the time interval from the instant the first bit of the initial SETUP message
containing all the selection digits is passed by the calling terminal to the access signalling system until the last bit of the
first message indicating call disposition is received by the calling terminal (ALERTING message in case of successful
call) (see ITU-T Recommendation E.721 [2]).
ETNS service: a service that has been assigned a European Service Identity (ESI).
ETNS service provider: an entity that provides one or more ETNS service(s) to its ETNS Subscribers on a contractual
basis.
ETNS subscriber: an entity that requests a European Number from a ETNS Service Provider in order to offer access
from a Calling Party to an ETNS service.

4 Structure of ETNS service numbers
4.1 Numbering scheme
The ETNS numbering scheme upon which the requirements in the present document are based assumes the use of a
specific Country Code (CC) assigned to Europe (CC-388).
Subclauses 4.1.1 to 4.1.3 describe this scheme.
4.1.1 European Number (EN)
To implement the European Country Code (CC) scheme the allocation of a specific CC is required. The European CC is
used to identify a set of ETNS services provided in two or more ETNS countries, instead of designating a specific
country. Figure 1 describes the structure of the ETNS number.
