    EXECUTIVE SUMMARY

    1The ETNS is a numbering space intended for the implementation of pan-

    2European services. The objective is that ITU will allocate a three-digit CC to the

    ETNS to overlay the existing European CCs.

    3Based on the application to ITU signed by 24 European countries, it reserved, in May 1997, the CC 388 for ETNS testing. ITU made this reservation with three

    conditions:

    - the code was to be used only for a field trial during the reservation

    period

    - the reservation would terminate at the closing of the first ITU-T4

    Study Group 2 meeting in 1999

    - the applicant would provide twelve points of information re-

    quested by ITU

    The field trial comprises two phases:

    - phase 1, to prepare a business plan to assess the feasibility of the

    trial and a work plan for the trial, and to identify necessary actions

    and time-schedules needed for the implementation of the trial

    - phase 2, to carry out the necessary actions needed to implement

    the trial

    This work order covers only phase 2. ETO

    5 carried out phase 1 under a separate

    6mandate from the CEC.

    According to the phase 1 conclusions, the European Access Number (EAN) ser-

    vice was implemented in phase 2. This service is generic and can support several

    applications.

    Two pan-European networks (Interoute and Tele2) participated to implement the

    ETNS translation capabilities. Several originating networks participated in the

    trial. Terminating networks can potentially be any network inside or outside

    Europe.

    The following four originating networks implemented ETNS facilities for the trial:

    - Tele Danmark

    - Telecom Eireann

    - Tango

    - Comviq The trial used a simplified charging scheme.

    In principle, the SPs should charge the ETNS subscriber for the ETNS service ac-

    cording to a contractual agreement established during the subscription phase.

    However, during the trial, the subscribers receive no charges for incoming calls.

    During the trial, the participants tested number portability by porting one of the

    numbers allocated to Tele2 (a CEC EAN) to Interoute.

    The originating networks involved enabled potentially several million subscribers

    to make calls towards ETNS numbers during the trial. In addition, Interoute im-

    plemented the routing of ETNS number from its networks in the USA and Canada

    via indirect access.

    ETO acted as Administrator and Registrar for ETNS during the trial. Accordingly,

    ETO implemented some simple facilities in order to be able to manage and allo-

    cate ETNS numbers. It allocated an ESI

    7 for the EAN service and defined a

    simplified procedure for EAN number allocation based on the ETO report for the

    management of ETNS.

    The information collected in the trial enabled ETO to establish the responses to

    the ITU points. ETO produced the contribution a May 1999 on behalf of 24 Euro-

    8pean countries and presented it to ITU after approval from the CEC, ECTRA,

    910and the ENF. The Q1/2 Rapporteur Group discussed the contribution in Geneva

    on 13 May 1999.

    The discussion resulted in these agreements:

    - the assignment of CC 388 for ETNS was not made at the meeting

    - the conditional reservation of 388 was extended to March 2000 for

    use during an ongoing ETNS trial

    - the ITU would afford Europe the opportunity to address the con-

    cerns expressed at the meeting regarding their application and

    presentation

    - there would be no assignment of a regional CC until Project 27

    had completed the “Criteria for the Assignment of Regional Coun-

    try Codes”

    1. PRESENTATION OF THE STUDY

    In reading this document, you should have in mind that it provides a report on the

    status of phase 2 of the ETNS field trial in the third quarter of 1999. The trial will

    continue until at least the first quarter of 2000.

    The CEC and ETO decided to proceed with phase 2 of the trial following the posi-

    tive results from phase 1.

    ETO would take all appropriate steps to secure permanent allocation of CC 388

    for Europe; in particular it would:

    - manage the phase 2 implementation of the trial in order to achieve

    the objectives of the business and work plans generated during

    phase 1

    - continue the work of the Steering Committee and the Working

    Group established in phase 1

    - administer the ETNS, including the allocation of ESIs, in

    accordance with the trial conditions set out by ITU

    - fulfil the functions of the ETNS Registrar for the purposes of the

    trial

    - present the case for permanent allocation of CC 388 to Europe,

    responding, as appropriate, to the points of information requested

    by ITU in its reservation of CC 388

    - promote the concept of the ETNS A draft response to ITU was delivered in February 1999 to the CEC for approval.

    This was then be forwarded to the ECTRA/PT N

    11 meeting in March 1999 for

    12approval and presented at the ITU-T SG2 meeting in May 1999.

    Chapter 2 of this report describes the ETNS implementation undertaken by the

    trial participants in phase 2. It provides a detailed description of the service, the

    network architecture, and the technical and operational options that the partici-

    pants are using in phase 2.

    Chapter 3 reports on the discussion, concerns, and conclusions of the Q1/2 Rap-

    13porteur Group meeting and proposes the necessary future action. Chapter 4 presents the conclusions and proposals from the study.

    The ETNS trial project involved the following parties:

    - The operators and SPs who participated in the trial (Interoute, Eu-

    rofone, Tele2).

    - European local loop operators who acted as originating networks

    such as Telecom Eireann and Tele Danmark. Tele2 Europe repre-

    sented the mobile originating networks.

    - Arcome as project manager and co-ordinator of the implementa-

    tion of the trial.

    - ETO as supervisor of the trial and as Administrator and Registrar

    for the ETNS.

    - The CEC.

    - ECTRA

    - ENF

    The management was organised in the same way as in the first phase: a Working

    Group and a Steering Committee. Arcome chaired the Working Group where the

    field trial participants attended. ETO chaired the Steering Committee, which was

    composed of Arcome, the CEC, the ENF, and ECTRA.

    The CEC gave a clarification in 1998 about the funding policy of TEN-Telecom

    projects. It was clear that the funding procedures for these projects were not com-

    patible with the project period.

    The CEC gave the formal decision to start phase 2 of the ETNS trial at the end of

    1998. However, the Working Group kept working on the project without interrup-

    tion from June to December 1998. The participants achieved the major parts of the

    implementation in the ETNS backbone by December 1998. They introduced the

    other originating networks in early 1999.

    The trial participants have, in addition, started working on the preparation of a

    framework for the commercial phase of ETNS in order to clarify some concepts

    related to ETNS such as charging, billing, and interconnection fees.

    ETO plans the following timetable:

    - this interim report 8/99

    - agreed interim response on Project 27 7/99

    - response on Project 27 to ITU 9/99

    - draft response on SG2 concerns 10/99

    - European preparatory meeting for ITU 1/99

    - revised response on Project 27 2/99

    - response on SG2 concerns to ITU 2/99 The final report, including a report of progress against the business and work

    plans and a report on the perceived viability of the ETNS will be delivered to the

    CEC in fifteen bound copies, one unbound copy and one copy on floppy disk in

    Microsoft Word 97 in April 2000.

    2. PROGRESS REPORT ON PHASE 2 OF THE TRIAL

    14On the basis of phase 1 of the ETNS trial, the CEC and ETO decided to proceed with phase 2 of the trial.

    This chapter describes the system established to implement phase 2 of the ETNS

    field trial.

    The chapter provides a detailed description of the service, the network architec-

    ture, and the technical and operational options that the participants in phase 2 have

    been using.

    2.1 ETNS Service for the Field Trial

    In accordance with the phase 1 conclusions, the European Access Number (EAN)

    service was implemented in phase 2. This service is generic and can support sev-

    eral applications.

    2.1.1 Service Description of the European Access Number

    The EAN service enables subscribers to have an ETNS number allocated to them

    independently of their geographic location. Applications of the EAN service may

    be attractive for the following classes of subscribers:

    - European organisations which can have a range of EANs to enable

    callers to contact them through a harmonised ETNS range of

    numbers. We foresee the CEC

    15, the European Parliament, the

    1617European bank, ETSI, ETO, and similar European organisations

    as strong potential users of this service. At present, these organisa-

    tions are located in different European countries with different

    18CCs. A homogeneous numbering scheme will facilitate access to

    these organisations. This will make it easier for international call-

    ers to reach European organisations.
