    EXPLANATORY MEMORANDUM
I.   INTRODUCTION
    The Telecommunications Council of December 1989 decided that the Community's
    telecommunications policy should combine in a balanced way harmonization and
    liberalisation.
    Consequently, on June 28, 1990 the Council of Ministers for Telecommunications
    adopted      a   Directive       on     the   establishment                of         the     internal    market   for
    telecommunications services through the implementation of open network provision
    (ONP) and the Commission adopted a Directive on competition in the markets for
    telecommunication services.
    The first Directive (known as the ONP framework Directive), considers the area of
    packet switched data services (PSDSs) as a priority. The Directive received broad
    support in the European Parliament and in the Economic and Social Committee. The
    Directive asks for the implementation of harmonized technical interfaces and/or
    service features for PSDSs and in this respect the Commission published in the
    Official JournaP on the 29.12.90 the list of packet switched public data networks
    standards suitable for ONP. The Directive also foresees as a priority the adoption of a
    Council Recommendation on the harmonised provision of a minimum set of Packet
    Switched Data Services in accordance with Open Network Provision (ONP)
    principles.
    It is in this context that the Commission presents this proposal for a Recommendation
    to the Council of Ministers.
II. T H E ROLE OF PACKET SWITCHED PUBLIC DATA NETWORKS IN T H E
     DEVELOPMENT O I : EUROPEAN V A L U E A D D E D SERVICES
    The late 70s saw the introduction of packet switched public data networks in several
     European countries.

   The introduction of these national networks followed different timetables and
   different commercial priorities however, and hence the availability of a fully
   harmonised and up to date international service was held up.
   From an industrial and manufacturing point of view it was only after 1976 that the set
   of packet switched associated standards reached a mature enough stage to allow the
   development and marketing of commercially exploitable packet switching public
   systems, although                           the        first packet switched                  public data                  networks were               not
   commercially available before 1978/1979^.
  Administrations began to plan for, and implement national packet switched services
  against a range of target dates, and some administrations were therefore working with
   more mature CCITT recommendations than those that had launched public services
  earlier.
  By 1984, when the new and revised CCITT recommendations (Red Book) became
  available, most European countries already had their packet switched public data
  networks up and running on the basis of different implementations of the 1980
  versions               of       CCITT                 recommendations,                   and   the         first      international               gateway
  interconnections                       between              networks had been                   established,                 based      on        bilateral
  arrangements without any administrative or management functions, for the provision
  of transborder services at European level.
  All these factors led to national variations of the basic service, which has made full
  international interworking difficult to achieve.
  The market for networks and services has clearly became application driven on an
  European scale, and incompatible products and services, as well as internal skills
  shortages are seen by the users as major constraints on data communications networks
  development over the next years.
  The development and availability of international value added services to support the
  applications required by the users is largely dependent on PSDSs because without
  such an adequate transeuropean transport service, higher layer value added services

     will be difficult to offer to users on a Community wide scale.
     Such services will flourish if, and only if, a high quality, reasonable priced, ubiquitous
     transport service is available.
     Existing packet switched public data networks have developed into a major transport
     media for the operation of value-added-services throughout the Community. Suitably
     expanded and enhanced to adhere to European standards, they offer the most suitable
     mechanism to meet the tight deadlines imposed by the 1992 Single Market goal on the
     availability of value added services necessary to support European wide industry,
     trade and administration.
III. THE CONSULTATIVE PROCESS
     The concept of ONP conditions for open provision of packet switched public data
     networks was introduced by the Commission                       in the Communication on the
     Implementation of the Green PapeA In its Council Resolution of 30 June 1988 the
     Council urged for the "rapid definition" of ONP conditions for public data networks.
     Since the Commission deemed it necessary that the analytical work on public data
     networks was taken up as soon as possible the Commission started to analyse the
     subject in parallel with its work on the ONP framework Directive. Preparatory work
     on the application of ONP principles to public data networks was therefore
     undertaken by the SOG-T (Senior Officials Group - Telecommunications) and its sub-
     group GAP (Groupe d'Analyse et de Prévision) as early as 1989.
     In the spirit of the then pending framework Directive, the SOG-T arranged for the
     participation       of   representatives      of   European      industrial organizations,   trade
     associations, service providers, telecommunications users, and telecommunications in
     general. To that end. public comments on the proposals^ of GAP were invited by
     notice in the Official Journal dated 6 April 1990.UK1 two fora were organized in

    March and October 1989 for public discussion of the proposals.
    Subsequently, a draft of the proposal for a recommendation was discussed with the
    ONP Committee.
    The present proposal for a Council Recommendation takes into account the results of
    a) the GAP analysis report, b) the comments received from interested parties in the
    course of the public comment process, and c) the comments received from the ONP
    Committee. At the same time it takes account of the general principles which have
    been laid down in the Directives on competition in the market of telecommunications
    services and in the ONP framework Directive.
IV. THE APPROACH ADOPTED
    The proposal implements a concept of harmonization in the areas of standards, usage
    conditions, supply conditions and tariff principles.
    The proposed Recommendation refers in its recitals to some of the general principles
    resulting from Community law. The operative part then specifies in detail how a
    minimum set of PSDSs should be provided in a harmonised way in accordance with
    Open Network Provision principles.
    The points of the Recommendation are briefly explained hereunder :
    Provision of a minimum set of PSDSs
    Point 1 defines a minimum harmonised set of PSDSs with harmonised technical
    characteristics which must be made available throughout the Community. The point
    also sets a timetable for the provision of these services, where not available. For this
    minimum set, reference is made to the list of packet switched public data networks
    standards suitable for ONP published in the Official J o u r n a l 0 (see table 1).
    Point 2 provides for the mechanism to update this set which is described in Annex II
    on the basis of changes in market demand and in technology. Changes in Annex II can
    be made by the Commission, in cooperation with the ONP-Ounmittce. Such changes

       may incorporate the removal of or the addition of PSDSs to the list.

                                                                  (90/C 327/12)
Pursuant to Article 5 (1) of Directive 90/387/EEC (') the Commission publishes a list of
standards which constitutes a basis for harmonized access ' and/or service features in the
context of open network -provision.
Given the fact that many of these standards are not yet finally adopted ('), changes may occur.
As a consequence these standards are now being published as an indicative list. Therefore this
list may be amended by further publication in the Official Journal of the European Communities
pursuant to Article 5 (4) of Directive 90/387/EEC.

 Disclosure of information
 Point 3 establishes the format in which the information is to be published in order to
comply with the requirement that ONP conditions must be transparent and published
 in an appropriate manner.
Supply Conditions
The supply conditions for PSDSs are addressed in Point 4. It requires organizations to
use a set of general supply conditions which contains at least a number of parameters
which are of vital importance to users, e.g. the delivery period for a type of PSDS, the
duration of the contractual period and the repair time. It also refers to the refund
policy and the network performance targets.
Common ordering, hilling and maintenance procedures
Point 5 expresses the requirement of users to be able to order PSDSs in a common
fashion, and where requested, to be able to communicate with a single organization
for ordering, billing and maintenance purposes.
Through the implementation of a "green number" arrangement at a Community level
it allows, on the one hand, for the establishment of permanent arrangements for
reverse charging capabilities allowing Community wide service providers to bill their
customers in a global bill. The "kiosk type arrangement" allows, on the other hand, for
the possibility of a combined collection, in a global bill, of the cost of the value-added
service and of the cost of the call, by the organisation supplying PSDSs, thus
facilitating the provision of value-added services across the Community, specially by
small and medium size service providers.
Quality of Service
Points 6 and 7 refer to quality of service and ask for the adoption of common
indicators for     the network performance       aspects of quality of service, and
corresponding measurements methods. Both are indicated in Annex III.
 ---pagebreak---                                          - 8 -
 Tariffing Principles
 Points 8 and 9 refer to the basic principle of application independence which is to be
 applied for tariffs of PSDSs and identifies separate tariff elements which will normally
 be contained in the tariffs.
Notification
Points 10 and 11 deal with the information which the national regulatory authority has
to provide to enable the Commission to monitor the implementation of this
 Recommendation, notably which organizations will conform with the provisions of the
 Recommendation.
User Support
Point 12 refers to a procedure for user support if difficulties are encountered in
relation to the objectives of this Recommendation, in particular in connection with the
provisions on the general supply conditions and quality of service.
Progress of work
Point 13 recommends that the Commission examines the progress of work in
implementing the Recommendations in consultation with the ONP Committee.
CONCLUSIONS
Directive 387/90/l:I : :C calls in its Annex 111.3 for the adoption by the Council by 1
July 1991, acting on a proposal from the Commission, of a recommendation on the
supply of technical interfaces, conditions of usage and tariff principles applying to
provision of packet switched data services complying with open network principles; at
the same time this recommendation would in particular call on Member States to
ensure at least one such service was provided on their territory.
The present Commission proposal for a Council Recommendation on the harmonised
provision of a minimum set of Packet Switched Data Services in accordance with
Open Network Provision (ONP) principles takes account of the. harmonized general
principles laid down in the. ONP Iraniewoik Diiective and specifics which services
 ---pagebreak---                                      -   9 -
should be provided in all Member States in a harmonized way. It is flexible and open
for future adaptation in line with market demand and technology progress. Thus, the
proposal significantly   improves the competitive conditions in the European
telecommunications market.
The Council is therefore requested to adopt the attached proposal for a
Recommendation.

a harmonized packet-switched data service (PSDS);
Whereas in application of the principle of non-discrimination, PSDSs shall be available and
provided on request without discrimination to all users; therefore the terms and conditions
which apply to telecommunication organizations when using PSDSs for the provision of
competitive services must be equivalent to the terms and conditions which apply to other
users;
Whereas in accordance with Directive 90/387/EEC, the conditions of Open Network
Provision may not restrict access to and use of PSDSs except in application of essential
requirements as defined in the said Directive; those restrictions must be objectively
justified, must follow the principle of proportionality and must not be excessive in relation
to the aim pursued;
Whereas in accordance with Article 3(5) of Directive 9 0 / 3 8 7 / E E C the Commission will
determine the rules for uniform application of the essential requirements;

 trade regulations relating to conditions of permanence, availability and quality of service,
 or measures to safeguard the task of general economic interest which they have entrusted
 to a telecommunications organization for the provision of switched data services, if the
 performance of that task is likely to be obstructed by the activities of private service
 providers;

Whereas in accordance with Directive 90/387/EEC, the Commission has published in the
Official Journal'* the list of packet-switched public data networks standards suitable for
ONP; this list may be amended by further publication;
Whereas common ordering procedures, one-stop-ordering and one-stop billing and
maintenance are essential to promote the use of PSDSs throughout the Community; any
cooperation of the organizations in that respect is subject to compliance with Community
Competition law; in particular, such procedures should not result in any price fixing or
market sharing; these procedures are to be promoted through market mechanisms, e.g.
through Memoranda of Understanding between the organisations supplying PSDSs, in
accordance with t h i s Recommendation;
Whereas in order to promote Europe-wide            operation by service providers using PSDSs it
is desirable to allow for a system where the called party pays for the calls on the basis of the
number called, allowing the offering of free-of-charge calls to the subscriber accessing the
service offered by the provider (green number);
Whereas in order to promote the use of PSDSs by small-and medium-size providers of
value-added services it is desirable to establish billing arrangements which facilitate such
operations across the Community; such billing arrangements should allow for a system
where the cost of the value-added service and the cost of the call are combined in a single
bill collected by the organisation supplying PSDSs ("Kiosk type arrangement");
Whereas it is important in this context that appropriate allocation of harmonised

HEREBY RECOMMENDS:
1. That Member States ensure the provision of a minimum set of PSDSs with
   harmonised technical characteristics in accordance with Annex I, taking account of
   market demand.
2. That the Commi.ssion determine the modifications necessary to adapt Annex I to new
   technical developments and to changes in market demand in accordance with Article 9
   of Directive 9 0 / 3 8 7 / E E C .
3. That Member States ensure that information in respect of the PSDSs provided in
   accordance with point 1 on technical characteristics, general supply conditions, usage
   conditions, tariffs and the conditions for the attachment of terminal equipment is
   published in accordance with the presentation given in Annex II.
4. That the general supply conditions referred to in point 3 include at least:
   - the typical delivery periods, which are the periods, counted from the date from
      which the user makes a firm request for the service in question, in which 80 percent
      of the demands for the PSDSs has been put through to the users.
      Each period shallbeestablished on the basis of the actual delivery periods of the
      PSDSs in question during a recent time interval of reasonable duration. The
      calculation must not include cases where late delivery periods were requested bv
      users. For new type's of PSDSs a target deliverv period shall be published instead of
      the typical delivei y pei iod;
   - the contractual pei iods . which include the peiiods which are in general l a i d down
      for the contracts and the minimum contractual periods which the user is obliged to
      accept for the PSDSs;
 ---pagebreak---                                               - 15 -
     the typical repair times , which are the periods, counted from the time when a
     failure message has been given to the responsible unit within the organizations
     supplying PSDSs up to the moment, in which 80 percent of the reported PSDSs
      have been repaired and notified back in operation to the user. For new types of
      PSDSs a target repair time period shall be published instead of the typical repair
     time. Where different classes of quality of repair are offered for the same PSDS,
     the different typical repair times shall be published.
      the refund policy,
     indicators for quality of service established in accordance with point 6.
5. That Member States, taking into account the work of CEPT 5 , note the value and
   promote the establishment, in conformity with the procedural and substantive rules of
   the Treaty and in consultation with users, of harmonised procedures for user access
   the PSDSs, in particular via the establishment of the following procedures:
   - a common ordering procedure, i.e. an ordering procedure for the procurement of
      intra-community PSDSs which ensures that there is commonality across the
      organizations supplying PSDSs in the information that has to be supplied by the
      user and the organization supplying PSDSs, and in the format in which the
      information is presented;
   - a one stop ordering procedure, i.e. a system whereby all transactions involving a
      user, required for the procurement of intra-community PSDSs supplied by more
      than one organization, can be completed between the user and a single organization
      supplying PSDSs;
   - a one-stop-billing procedure, i.e. a system whereby the payment transaction for
      intracommunity PSDSs supplied by more than one organization to a single user can
      be completed at one location between the user and a single: organization supplying
      PSDSs, and

   - a one-stop-maintenance procedure, i.e. a system whereby the reporting of faults for
     intracommunity PSDSs supplied by more than one organization to a single user can
     be done at one location between the user and a single organization supplying
     PSDSs, which will take full responsibility for restoration of service.
   These procedures should include the establishment of Community - wide service
   arrangements allowing for:
   - a capability where the called party pays for the calls (Green Number);
   - a capability where the cost of the value-added service and the cost of the call are
     combined in a single bill collected by the organisation supplying PSDSs (Kiosk type
     arrangements).
   These procedures are to be promoted through market mechanisms, e.g. through a
   Memorandum of Understanding open to all organisations supplying PSDSs in
   accordance with t h i s Recommendation.
6. That common indicators for the network performance aspects of the quality of service
   and common measurement methods be adopted, notably for those indicators in
   Annex III.
7. That the national regulatory authorities ensure the availability of periodic, statistical
   reports showing the performance in relation to the quality of service indicators, in
   accordance with point 6, at least for each calendar year, from 1 January 1993.
8. That tariffs be based on objective criteria and             independent of the type of
   application implemented by the users of the PSDSs, where the same type of facilities
   are used.
 ---pagebreak---                                                              - 17 -
9.   That the tariffs for PSDSs normally contain the following elements :
        -an initial Charge,
        -a periodic Rental Charge,
        -a usage charge, including normally a fixed per call charge based either on a
        minimum time and/or volume charge or a call set-up charge, a volume related
        charge based on the use of an integral number of segments0 , and a duration
        related charge based on an interval of time sufficiently short to avoid discrimination
        against short type transactions.
     Where other tariff elements are applied, these must be transparent and based on
     objective criteria.
10. That the national regulatory authorities notify the Commission before 31 December
     1991 of the organizations which provide PSDSs in accordance with
     this Recommendation, and thereafter of any changes to this information.
11. That the national regulatory authorities ensure the availability of summary reports in
     particular with regard to the availability of PSDSs provided in accordance with point
     1, the implementation of the general supply conditions under points 3 and 4 and the
     reports under point 7 at least for each calendar year and that the summary reports be
     sent to the Commission no later than 3 months after the end of the annual reporting
     period.
 12. That the national regulatory authority ensure the establishment of an ea.sy procedure
     for users of packet-switched data services to invoke with regard to any difficulties
     encountered in relation to the objectives of this Recommendation, in particular in
     connection with points 1 . 3 , 4 , 6 and 0;

 DEFINITION OF A COMMUNITY WIDE MINIMUM SET OF PACKET SWITCHED
 DATA SERVICES WITH HARMONISED TECHNICAL CHARACTERISTICS IN
 ACCORDANCE WITH POINT 1 AND TIMETABLE FOR THEIR AVAILABILITY
A   GENERAL CONSIDERATIONS
   The Recommendation aims at the harmonised provision of a minimum set of PSDSs
    in accordance with Open Network Provision principles to users in order to facilitate
    the development of European wide services.
   These services should:
    i)be made available on an adequately unbundled basis in order to give users maximum
        flexibility.
    ii)be structured in the following way (on a service basis):
                ONP Core Offering
                - access/ feature set(s) which must be offered by all networks;
                - user selects (one) set in order to have the basic service
                - set to be tariffed as a bundle.
                ONP User Options
                - feature offered by all networks on an individual basis:
                - feature which may be selected by user;
                - may in specific cases substitute Core offerings features.
     iii)take into account technological development and the growth in availability of
         features not considered in the proposed service.

         B   STANDARDS TO BE APPLICABLE
             The standards applicable for this minimum set of PSDSs with harmonised technical
             characteristics are in particular those in the indicative list of packet switched public
             data networks standards suitable for ONP published in the Official Journal 1 ,

INDICATORS FOR THE NETWORK PERFORMANCE ASPECTS OF THE QUALITY
OF SERVICE OF PSDSs
   Common indicators for the network performance aspects of the quality of service of
   PSDSs and common measurement methods should be adopted in order to allow for
   the determination of a representative sample of the performance of user's direct
   access to the PSDSs as well as the end-to-end statistical performance achieved by the
   network as a whole.
   Such indicators for the network performance a.spects of the quality of service of
   PSDSs and measurement methods should be based on the ongoing work in CEPT, and
   notably on Recommendations T/CAC 2 3 , T/CAC 3 A , T/CAC 4 5 .
   For each of the above performance criteria, indicators should be chosen which are
   representative of the service:
   Availability                Unsuccessful Network Congestion (NC) calls ratio (UNCR),
                               Service availability,
   Dependability               Mean time between NC disconnections (MTNC),
   Speed of service            Transmitted throughput (TIT),
                               Received throughput (RTP),

Results of network performance measurements should be made publicly available, so
that users of PSDSs can be informed about the achieved levels of performance for
national and European services.These statistics should permit comparison with the
established target values for network performance, to be published under Point 3 of
the Recommendation.
