SUMMARY 
The purpose of this communication is to propose a set of measures concerning the 
development of ISDN as a trans-European network (TEN-ISDN) in order to support the 
availability of an advanced telecommunications infrastructure, so that all participants of the 
internal market, and notably the many small and medium sized enterprises have better 
chances to exploit the benefits of the market without internal frontiers 
Such an advanced infrastructure, once in place, will thus contribute to the functioning of 
the internal market and to the re-inforcement of the competitiveness of Europe. 
ISDN, is a general, multi-purpose network integrating a large variety of voice, data and 
image services via a single network access. Given that ISDN is evolving out of todays 
telephone network, it has a natural vocation as European-wide network. 
Since 1984, ISDN is a key subject of the Community's telecommunications policy, the gist 
of which is to arrive at harmonised introduction of ISDN in all Member States. 
Several Council measures have focussed on the coordinated introduction of ISDN and in 
June 1992, the Council has underlined the importance to develop ISDN as a trans-
European network. 
Based on the provisions of the Treaty and on the preceding Council measures referred to 
above, the Commission is proposing a framework for a Community-action with the 
following elements: 
First, the adoption of a series of guidelines for the development of ISDN as a trans-
European network covering the objectives, priorities, broad line of measures and the 
projects of common interest. 
Secondly, the adoption of a multi-annual Community-action concerning the 
implementation of the projects of common interest and measures in support of 
interoperability. This Community-action will include mainly feasibility studies and 
implementation support in the form of interest rate subsidies and loan guarantees. Only 
measures where the defined objective cannot be attained by an action at the level of the 
Member States are covered. 
Thirdly, the setting up of a high-level coordination group assisting the Commission in the 
execution of the multi-annual action. 
Finally, with a view to the global nature of ISDN, the Commission proposes to begin 
exploratory discussions with non-EC countries, the EFTA in particular, to assess how far 
projects of common interest can be extended to those countries. 
This communication is accompanied by two proposals for Council Decisions, one on the 
overall guidelines, the other on the multi-annual Community-action. 
1. ISDN AS TRANS-EUROPEAN NETWORK : 
THE REASONS FOR A NEW PHASE OF COMMUNITY ACTION 
1. One of the goals of the Community's telecommunications policy is to promote a 
telecommunications infrastructure based on interconnected networks integrating a 
number of harmonised services covering the whole of Europe. 
A recurring feature of the development of networks in European countries in the 
past has been the creation of independent infrastructures developed at national 
leveL This has militated against the introduction of harmonised services throughout 
Europe and has generated a series of technically incompatible systems. 
2. It is clear that to continue such a policy would be at odds with the aims of the single 
market 
The completion of the single market will not only lead to new communications 
requirements between administrations1, the free circulation of goods, services, 
persons and capital will equally generate new communications requirements 
between the economic participants in the single market. 
It is widely recognised, that a tissue of performant SME's2 are of particular 
importance for the development of a competitive market. SME's can often not 
afford dedicated solutions like corporate networks or specific applications. Thus, 
they depend on an adequate public service offering. Given the number of 
approximately 10 million SME's in the Community, it is clearly of advantage, if all 
these SME's have the option to access the same general switched 
telecommunications network. 
3. Since 1984, ISDN3 is a key element of the Community's telecommunications policy. 
ISDN is conceived as the natural evolution of the telephone network, based on its 
existing structure. 
ISDN, due to its advanced technology, developing status and promise of a wide 
range of voice and data services, was seen as a prime vehicle to satisfy the 
telecommunications needs of the single market. Subsequently, the Council adopted 
in December 1986 the Recommendation on the coordinated introduction of ISDN 
in the European Community4, which proposed a timetable for a phased 
introduction of ISDN services according to harmonised standards for interfaces and 
equipment.

4 Council Recommendation of 22 December 1986 on the coordinated introduction of the Integrated Services 
Digital Network (ISDN) in the European Community (86/659/EEC; O J. L382/36) 
ISDN is the subject of "Annual Progress Reports" in the form of Commission 
Communications. These reports have led to two Council Resolutions on ISDN. In 
1989, the Council adopted a Resolution on the strengthening of the coordination 
for the introduction of the ISDN in the European Community up to 1992s and in 
June 1992 a further Resolution which underlines the importance to the develop 
ISDN as a trans-European network6. 
The introduction of ISDN in the less favoured regions received a contribution of 
the STAR programme7. 
ISDN is furthermore one of the priority areas for the application of the ONP8 
principles. 
With regard to ONP it is important to note that the initiatives on ISDN in ONP and 
in TEN are complementary, and in fact constitute a necessary reinforcement of two 
aspects. The first is the regulatory environment, which is designed as to enable an 
open and non-discriminatory access to public networks by value-added services 
providers for the sake of the growth of new services in a competitive market The 
second aspect is the promotion of an infrastructural development which supports 
the functioning of the single market through the instruments foreseen in the TEN 
framework. 
ISDN is a circuit switched network with a basic bitrate of 64kbit/s which 
integrates a wide variety of services for voice, data, text and images accessible to 
the user via one single interface. In comparison to the telephone network ISDN will 
offer better quality and higher throughput. For example, the transmission of one A4 
page per facsimile over the telephone network takes roughly one minute whereas 
with ISDN the same transmission will only take 3-4 seconds and provides much 
better quality (higher resolution). 
Annex A provides more details about the ISDN concept. 
4. The gist of the ISDN policy of the Community since 1984 was the coordinated 
introduction of ISDN in the Member States. Harmonisation of the user/network 
interfaces enabling the development of a mass terminal market and the access to 
standardised connection types which facilitate the provision of (third party 
provided) value added services (VAS) are crucial aspects of that policy. 
5. ISDN has a vocation as general switched network throughout Europe and on a 
world-wide basis. Owing to this nature ISDN is well suited to address many 
communications requirements from the public and private domain throughout the 
Community.

6. ISDN is a commercial reality in six Member States. However, the current 
implementations are technically not yet harmonised to the extent required. 
Furthermore, owing to a variety of reasons set out in detail in the Commission 
Annual Progress Reports on ISDN in the Community, the initial timetable for the 
introduction of harmonised ISDN offerings could not be met. 
In the course of 1993, ISDN, based on harmonised standards elaborated by 
ETSI9 will be introduced. This harmonised form of implementation is referred 
to as: EURO-ISDN. 
Therefore the current situation of ISDN in the Community can be described as a 
situation of transition, from existing national implementations to EURO-ISDN. 
All public network operators of the Community have signed a Memorandum of 
Understanding (MoU on ISDN) in which they commit themselves to implement 
EURO-ISDN. The full scale deployment of EURO-ISDN will extend over a number 
of years. 
It is the introduction of EURO-ISDN conformant facilities and/or upgrading of 
existing ISDN offerings to EURO-ISDN capabilities which are the subject of this 
proposal. 
Annex B provides a definition of the scope of EURO-ISDN. 
7. Only a general availability of this modern type of telecommunications infrastructure 
will allow to cater for the objective of economic cohesion. It is important that the 
peripheral regions will not lag behind with the implementation of EURO-ISDN in 
a way which adds further disadvantage. 
On the other hand, for the economic actors in the developed regions, the full 
potential of this basic infrastructure can only be obtained if they can reach all 
regions of the Community via the same network. 
8. Many efforts have already been undertaken by the public network operators and 
the Member States. However, not all aspects required for a successful Community-
wide introduction of EURO-ISDN are yet in place. Additional efforts at the level of 
the Member States and at the Community level to ensure the general availability 
and the harmonised provision of a number of basic services throughout the 
Community are necessary. 
9. The current transition from existing ISDN offerings to the harmonised EURO-
ISDN in the context of the requirements and opportunities arising from the 
completion of the single market provides the opportunity to embark on a new 
phase of the ISDN policy.

The present Communication sets out a framework for possible Community-action 
which could usefully be added to the efforts already undertaken in the Member 
States. It contains a series of guidelines describing the objectives and priorities 
and contains proposals for broad lines of measures and projects of common 
interest which are suitable to contribute to the achievement of the objectives and 
priorities. 
In conjunction with the present Communication, Part II of the present document 
presents two proposals for Council Decisions. 
A first proposal for a Council Decision presents the series of guidelines (Schéma 
Directeur) for the development of ISDN as trans-European network. 
The second proposal for a Council Decision is intended to institute a multi-annual 
programme for the implementation of TEN-ISDN guidelines. 
The proposed Decisions are based on Article 235 of the Treaty of Rome. 
The latter decision is accompanied by a financial statement. 
The approach for setting up the appropriate framework for the implementation of 
the proposals is described in Sections 3 and 4. It is foreseen to establish a multi-
annual Community TEN-ISDN action. Section 6 explains also in more detail why a 
Community action in favour of ISDN is appropriate. 
The second proposed decision foresees that the Commission will be assisted by an 
advisory Committee (c/f. Section 4.2 of the present Communication). Furthermore, 
in order to allow for a direct dialogue with the principal sector actors concerned by 
the TEN-ISDN measures, a "Coordination Platform" (c/f; Section 43 of the present 
Communication) is proposed. 
Given that ISDN is suitable to respond to many private and public needs, particular 
emphasis is attached to the objective to find out where applications which will be 
the subject of a parallel proposal for trans-European networks for the telematic 
networks between administrations10 (TNA-IDA), may benefit from the availability 
of ISDN. 
Reference is also made to the next generation of switched networks, Integrated 
Broadband Communications (IBC), which technological development was and 
continues to be the subject of Community RDT-action in the context of the 
programme RACE. It is the intention to prepare also for IBC a proposal in the 
context of the trans-European networks. 
Close coordination with these other proposals for trans-European networks in the 
sector of telecommunications (TNA-IDA, TEN-IBC) will be ensured. It is expected 
that synergy effects notably in the area of harmonisation of protocol architectures 
for telematic services can be achieved.

trans-European data communications networks between administrations;

The implementation of the measures presented in this proposal to develop ISDN as 
a trans-European network will have to take into account the evolution of the 
regulatory regime. As foreseen in the first two Community measures adopted in 
1990" concerning the open access to public networks and the competition in 
telecommunications services, the Commission undertook in 1992 a review of the 
situation of telecommunications services in the Community. After thorough 
discussions of the Commission document and in particular its proposals, the 
Commission has adopted a Communication to the Council and the European 
Parliament12 on 28.04.1993 proposing a series of steps to be taken in a phased 
approach up to the year 1998 concerning the regulatory evolution in the fields of 
telecommunications services and the provision of infrastructure. 
Regulatory changes in the course of the said evolution which would concern the 
development of ISDN as presented in this Communication will be fully taken into 
account. To this end, a revision clause is foreseen in Article 8 of the first of the two 
proposed Decisions. 
10. The present proposals have also to be seen in the context of the perspectives of the 
Communication COM(92) 2000 and COM(92) 200113 and in particular in the 
context of the Communication of the Commission to the Council on trans-
European networks14. 
The Council in its Resolution from 7 December 1992 regarding the means to ensure 
the good functioning of the internal market13 has stressed the urgency to reinforce 
the telematics and other communications networks. Hie present proposal to 
develop ISDN as a trans-European network responds to this requirement. 
Owing to its infrastructural nature, ISDN is also considered in the context of the 
growth initiative decided at the Edinburgh Council First discussions with the EIB 
for inclusion of ISDN projects in the temporary lending instruments have been 
held. Following the decision on the Delors II package, also the possibility for co-
financing with other Community instruments, notably with the structural funds are 
being explored.

SERIES OF GUIDELINES FOR ISDN 
11. Following the adoption of the Council Resolution of 5 June 1992, a series of 
guidelines covering the objectives, priorities, broad lines of measures and projects 
of common interest for the definition and implementation of ISDN as a trans-
European network were prepared. 
The graph on the next page provides an overview on this series of guidelines. 
From the outset a close cooperation of the sector actors was established for the 
elaboration of these guidelines. A Working Group (WG TEN-ISDN) with 
participation of the Public Network Operators and the authorities of the Member 
States discussed these guidelines. A framework for the envisaged Community-
action was defined. 
12. Proposals will be made how best to support the introduction of EURO-ISDN so 
that it meets the requirements of all the participants in the single market 
13. The main goal is the harmonised and rapid introduction of EURO-ISDN. The 
points of departure are the current ISDN commercial offerings which differ in 
various regards and the existing roll-out plans for EURO-ISDN of the public 
network operators. 
"Bottle-necks" In the plans for the deployment of the EURO-ISDN infrastructure, 
the range of services and various other aspects will be determined. For the 
infrastructure, a basic target date against which the plans will be evaluated is 
proposed (refer to paragraph 28). It is also proposed to include in the framework 
private ISDN networking, fully conformant to the relevant harmonised standards. 
A framework of measures to remedy those "bottle-necks" will be identified. The 
economic viability and the common interest of any project are key requirements. 
Interoperability and interconnectivity are the guiding technical principles for the 
proposals. 
14. Considerable emphasis is attached in the proposal to the availability of a number of 
compatible basic services (a platform of services) throughout the Community. 
Measures in support of interoperability of services offered over ISDN or accessible 
via ISDN are included. 
Also, a basic target date for the start of the practical availability of such a services 
platform is proposed here. 
2.1 OBJECTIVES 
15. The exploitation of the full potential of ISDN requires harmonised implementation 
throughout the Community. Two objectives can thus be defined for the 
development of ISDN as a truly general switched trans-European network.

POJECTS OF 
;CUMON INTEREST 
-12-
16. The first objective is related to development of a set of EURO-ISDN offerings 
which correspond specifically to the needs arising from the single market: 
Ol Availability of EURO-ISDN conformant facilities, including a basic set of 
harmonised services. 
17. Facilities conformant to EURO-ISDN means the implementation of harmonised 
user/ network interfaces on the basis of the relevant ETSI standards, i.e. the two 
ISDN access types basic rate access (BRA) and primary rate access (PRA). 
Harmonised services implies, that a basic set of services is available in accordance 
with the relevant European standards. 
The basic set of services will include, beside the one's which are defined in the MoU 
on the ISDN in Europe (c/f. Annex B ), those telematic services which correspond 
to the most urgent user needs: simple file transfer, access to electronic mail, 
generalised data bank access (including videotex), videophony and facsimile group 
4. 
Paragraph 32) and 33) contain further explanation of this item. 
18. In order to make sure that EURO-ISDN offerings in line with this objective are 
available to all potential users throughout the Community, a second objective is 
defined as follows: 
02 Full geographical coverage of EURO-ISDN offerings in all Member States. 
19. This objective includes the aspects of the coverage of EURO-ISDN infrastructure 
in the Member States (national connectivity) and international connectivity 
between thé Member States. 
National connectivity means the full scale deployment of the two harmonised 
EURO-ISDN user/ network interfaces types, basic rate access (BRA) and primary 
rate access (PRA). National coverage may be achieved by means of equipping local 
switches with EURO-ISDN capabilities or by other techniques like remote accesses. 
National connectivity also implies the upgrade of the national network signalling 
systems, so that they can support the full range of EURO-ISDN facilities. 
International connectivity implies the introduction of the agreed protocol (i.e. 
ISUP16 Version 1) in the international switching centres (ISC) of the Member 
States. While the current ISDN implementations allow international 
interconnections, different protocols are in use between ISC's which leads to a 
number of limitations, e.g. for service connections. Annex E provides an overview 
on the introduction plans for ISUP Version 1. 
20. The fulfilment of these objectives has to take account of the already existing 
national ISDN offerings and the existing plans to introduce EURO-ISDN.

22 PRIORITIES 
21. The priorities which are derived from the endeavour to develop EURO-ISDN 
rapidly as a trans-European infrastructure and from the objectives defined above 
take account of the date of the completion of the single market and the expected 
development of communication requirements in the Community. 
As stated in paragraph 6, all public network operators in the Community have 
signed the MoU on the introduction of EURO-ISDN. 
The current plans of the public network operators (c/f. Annexes C and D) foresee, 
that the introduction of EURO-ISDN will commence around the middle of 1993. All 
Member States will have launched EURO-ISDN by the end of 1993. 
22. The roll-out of EURO-ISDN will take several years. Some operators have 
confirmed targets for a country-wide coverage. In others, those plans do not yet 
exist and the geographical deployment will depend on demand. 
A strategy for the marketing of EURO-ISDN and the setting of a target date is 
required. 
23. All market analysis' suggest, that the early years of the ISDN roll-out will focus on 
professional users. The crucial role of the SME's for the economy was already 
underlined (c/f. Chapter 1). 
Therefore, the first priority is defined as follows: 
PI Rapid availability of EURO-ISDN offerings for all business users, in particular 
SME's. 
24. A second priority is aimed at the best possible usage of EURO-ISDN in the 
Community. Nowadays, many users of advanced telecommunications services make 
use of dedicated networks and services for their communications requirements. 
With a fully fledged EURO-ISDN it is conceivable, that a good portion of those 
users could find an economically interesting alternative in ISDN. 
P2 Maximisation of the usage of EURO-ISDN in the Community. 
25. A modern universally available harmonised multi-purpose service is a crucial 
prerequisite for the general Community objective of economic cohesion. 
Improvement of the access of the peripheral regions is therefore defined as third 
priority. 
P3 Facilitation of access of the peripheral regions by means of EURO-ISDN. 
-14-
Currently discussions betwëëhthe Member States and the Commission are held to 
revise the provisions governing the structural funds. In view of the infrastructural 
nature of ISDN and in the light of the requirement identified by the Commission17 
that until the year 2000 up to 40BECU will be required to expand and upgrade the 
telecommunications infrastructure in the less favoured regions (LFR's), a combined 
effort involving various financial instruments including the structural funds in 
favour of ISDN may be justified. The initiative for support from the structural funds 
lies with the Member States. 
23 BROAD LINES OF MEASURES 
26. The present section describes the proposed broad lines of measures which are 
devised in a way to best accomplish the objectives and priorities discussed above. 
Given that the objectives and priorities are of general nature, they apply in 
principle to all broad lines of measures discussed below. 
A fuller understanding of these lines may be derived from the projects of common 
interest which are described for each of these lines (c/f. Section 2.4). 
A framework for possible Community action is proposed. This framework enables a 
complementarity between measures in the Member States and an eventual 
Community-action. 
For the implementation of these measures emphasis will be placed on addressing 
the needs of business users and the peripheral regions. 
27. Four broad lines of measures are proposed. 
Given the priority of making EURO-ISDN accesses and basic services available to 
business users, it is necessary to eliminate "bottle-necks" in the existing deployment 
plans. 
LI Elimination of bottle-necks in the roll out of EURO-ISDN. 
Elimination of bottle-necks concerns the roll-out at the level of the Member States 
as well as the interconnection between the countries. 
With regard to the roll-out of EURO-ISDN facilities the existing plans of the 
PNO's show considerable differences for reaching full coverage. While in some 
countries this will be attained already by the end of 1994 or 1995, other operators, 
based on their specific situation have planned full coverage for the years 1996/97 or 
later. 
17 SEC(92) 1048 final from 21.10 1992, Page 32; 
-15-
An elimination of bottle-necks would in principle mean an acceleration of existing 
investment plans. In each case this will have to take account of business related 
arguments as well as a study of the demand in the geographical areas concerned. 
It could also mean an upgrading of existing pre-EURO-ISDN-offerings to conform 
with harmonised standards. 
28. Bearing in mind these considerations and in view of the functioning of the single 
market, a basic target date for the general availability of EURO-ISDN facilities for 
business users by the end of 1994 is set. This target date will serve as a reference 
against which plans are evaluated and will allow to determine measures which are 
suitable to narrow the gap between countries which plan a rather rapid introduction 
and others, in most cases more peripheral regions, where the current planning 
foresees full coverage for a point in time later than the target date. 
29. One of the major success factors of ISDN is the integration of a wide variety of 
services via two harmonised network interfaces. For many users this will do away 
with the necessity to subscribe to more than one telecommunications network. 
Discussions in the European ISDN User Forum (EIUF) have made clear, that in 
addition to telephony there is an urgent requirement for a number of compatible 
basic non-voice telematic services and applications available on a Community-wide 
basis. EURO-ISDN is designed to deliver or enable access to those services. 
In a previous Communication from the Commission, on the trans-European 
telematics networks between administrations (TNA) the crucial role of the 
availability of well defined telematic services for the proper functioning of the single 
market is set out in detail. 
Similarly, for the professional domain a basic telematic platform available 
throughout the Community is required in order to enable the economic participants 
of the single market to exploit the full economies of scale and scope of that market 
without internal frontiers. 
In order to allow all economic actors to have the option to use this telematic 
platform, this platform is only conceivable in connection to the coming generation 
of the general switched telecommunications network, the ISDN and later on the 
IBCNiC 
Indeed, not only the private domain will benefit from such a basic telematic 
infrastructure, many of the needs of the interchange of data between 
administrations (as for example discussed in the TNA-IDA proposal) are of similar 
nature. Consequently the TNA-IDA proposal makes reference to this fact, and a 
proper coordination between these two proposals in order to make sure that 
synergy effects can be realised is implicit to the adopted approach. 
In order to comply with user requirements, it is essential that those services and 
applications are provided in a manner which guarantees interoperability between 
user end systems and to promote measures with the objective to render the 
availability of such interoperable services more visible for the end user. 
18 Integrated Broadband Communications Network

30. So far, this user requirement is only met in part 
Therefore, a second broad line of measures caters for the interoperability of such 
services. 
The proposal takes account of the competitive context which is applicable for the 
provision of services other than voice. 
12 Ensure end-to-end interoperability of telematic services. 
31. Two major subheadings are planned for this action line: 
i) Creation of a common telematic platform and 
ii) Creation of a EURO-Label for interoperable services. 
32. A common telematic platform can be described as a set of telematic protocols 
which are arranged in an orderly manner (protocol stack) following a defined 
overall architectural concept. The term telematic platform implies a consensus on 
such a protocol architecture for the concerned services (see list below), where 
whenever possible certain protocol parts will be used for more than one service (eg. 
usage of the T.9019 protocol for a number of services). 
Five services for which there is particular demand are proposed to be included in 
the telematic platform: 
- simple file transfer; 
- electronic mail; 
- generalised access to data bases (including videotex); 
- videophony and 
- facsimile group 4. 
The final objective related to this proposal is the European-wide available to users 
of this set of services accessible via ISDN. 
33. The accessibility from the ISDN accesses to such services, for example from PC-
based ISDN terminals (eg. via PCI20) and the consideration of the impact of such a 
common protocol architecture for terminal end systems are further aspects. 
ISDN is specifically devised to support (by the appropriate channel and signalling 
resources which can depend on the services requested) such telematic services, 
although it is transparent with regard to the transport it provides for those (and 
other) services. 
In contrast to the direct infrastructure which is in the first place hardware based, 
services are typically software oriented. Software based solutions can easily be 
modified and hence this may lead to incompatibility.

34. The gist of the EURO-Label concept is therefore to support end-to-end 
interoperability on a basis of voluntary conformance to given specifications. 
There is a close relationship between the telematic platform and the EURO-Label 
proposal The range of services covered by the two measures would be principally 
the same. 
35. Given that a successful marketing of EURO-ISDN depends on the availability of a 
sufficient set of basic services, the timely availability of such services in relation to 
the timing of the roll-out of the infrastructure is important. 
It is therefore appropriate to set also for the availability of the above mentioned 
"telematic platform" a basic target date. 
The practical availability of the telematic platform should be by the end of the year 
1994, starting with some of the services (eg. simple file transfer, electronic mail) 
quoted earlier (i.e., the same date as set for the infrastructure). 
36. Today, a lot of customised applications, in the private and public domain are 
supported on dedicated networks. 
Indeed, much of the synergy which is expected from the merging of 
telecommunications and information technology, can be achieved from bringing 
(IT-) applications to the (general switched) telecommunications (network) 
together. 
37. A scrutiny of where it is economically and commerically appropriate to make use of 
the EURO-ISDN as wide area network for such applications is proposed. 
13 Migration of public and private sector applications to EURO-ISDN. 
38. One particular area proposed for the development of trans-European networks in 
the field of telecommunications are the telematic networks between administrations 
(TNA). In this context, a number of applications concerning the interchange of data 
between administrations requiring a wide area network support across the 
Community, will be developed. Migration possibilities of TNA-applications to 
EURO-ISDN will be studied under this broad line of measures. 
39. A further critical element for the successful development of EURO-ISDN is the 
availability of suitable and attractively priced terminal equipment. 
Owing to its current differences of the ISDN access characteristics, the ISDN 
terminal market is rather fragmented, based on national markets. 
Only the development of a truly Community-wide ISDN terminal market, which is 
only feasible with the introduction of the harmonised EURO-ISDN, will allow to 
exploit new economies of scale and thus contribute to the competitiveness of the 
Community market. 
This promotion of EURO-ISDN terminal availablity will take account of the fully 
competitive nature of this terminal market. 
IA Promotion of EURO-ISDN terminal availability. 
, -i8-
40. ISDN is a prime candidate for the development of a Community-wide terminal 
market. Only networks, which offer harmonised accesses, like for example EURO-
ISDN, will lead to the development of terminal equipment which can benefit from 
the "1-Stop TtyPe Approval" system as stipulated in the Council Directive 
91/263/EEC?1, and hence can freely circulate in the internal market without a prior 
need for technical adaptation or the requirement to be re-submitted to the type 
approval procedure for each national market. 
2.4 PROJECTS OF COMMON INTEREST 
41. For each of the broad line of measures established above, a number of projects of 
common interest are identified below. 
Typically, a first step of a project would be the conduct of a feasibility study (FS) 
which will in particular evaluate the economic viability of the projects. In certain 
cases it may well be feasible, to define directly the terms of reference of a project. 
The proposed projects are in line with the objectives and priorities set out earlier. 
2.4.1 PROJECTS RELATED TO LINE 1): "Elimination of bottle-necks in the roll out of 
EURO-ISDN 
42. In relation to this line a project of common interest which concerns the 
identification of bottle-necks and measures which contribute to their elimination is 
proposed. 
11 Identification of "bottle-necks", eg. in the roll-out of EURO-ISDN and measures 
which improve the availability of EURO-ISDN facilities. 
The identification here includes all kinds of bottle-necks, as for example, 
infrastructure, services, terminal availability, tariffs etc. 
43. A second project relates to the possibility to introduce a European-wide packet 
mode bearer services (PMBS) which is required for many data applications. At 
present, the implementation plans across Europe show a number of differences. 
12 Analysis of differences in the existing plans for the introduction of the packet-
mode bearer services and proposals which aim at the harmonisation of these 
implementations, in a manner that at least a Community-wide service can be 
offered. 
21 c/f OJ L128/1,23.05.91 
-19-
A harmonised European-wide PMBS is of crucial importance for many data-
applications, as for example POS^-transactions or PIN2* code verifications in the 
context of credit/ cash card usage. 
44. A final project relates to the specific requirements of the SME's in the single 
market. 
13 Development for transborder applications in particular corresponding to the 
needs of SME'-s. 
In the context of this project, it is envisaged to provide incentives for the definition 
and development of applications, which are at least shared by SME's from two 
Member States. 
Examples for such applications could be in tourism, where actual offers for holidays 
are communicated "on-line" via ISDN, or applications which support'the search of 
partner firms in other countries and which could be organised by International 
Chambers of Commerce. 
2.4.2 PROJECTS RELATED TO LINE 2): To ensure end-to-end interoperability of 
telematic services 
45. Two projects of common interest are put forward in relation to thé broàd line of 
measures No. 2. 
The first project concerns the development of the envisaged common telematic 
platform. It is re-called that five services have been identified as being of particular 
market interest: simple file transfer, electronic mail, generalised access to data 
bases (including videotex), videophony and facsimile group 4. 
More explanation on this issue is found in paragraphs 32) and 33). 
21 Development of a common telematic platform with particular attention to the 
five services listed. 
46. A second project concerns the promotion and visibility of end-to-end 
interoperability of EURO-ISDN services and terminals by the usage of a common 
label. This project will imply the definition of a concept for the EURO-Label, the 
set up of arrangements between the participants and initial support for the 
establishment of a EURO-Label organisation. 
22 Development of a voluntary EURO-LABEL.

2.43 PROJECTS RELATED TO LINE 3): "Migration of public and private sector 
applications to EURO-ISDN" 
47. Related to the line 3) on the migration of other applications to EURO-ISDN three 
projects of similar nature, but for distinct areas are proposed. 
Each of the projects will investigate into the feasibility and economic viability of 
using EURO-ISDN instead of dedicated networks. 
31 Migration of existing or planned TNA applications to EURO-ISDN. 
32 Migration of other applications (applications developed in the context of other 
Community measures, eg. health care networks, network between scientific 
parks, dedicated networks like IXI etc.) to EURO-ISDN. 
33 Migration of public and private sector applications operated on other networks 
to EURO-ISDN. 
2.4.4 PROJECTS RELATED TO LINE 4): Promotion of EURO-ISDN terminal 
availability 
48. Two projects related to the promotion of EURO-ISDN terminal availability are 
proposed. They will focus on cheap voice related terminals and on simple file 
transfer, electronic mail, generalised access to data banks (ind videotex), 
videophony and facsimile group 4. In terms of their technical scope the projects 
(41), (42) and (21) are related, i.e., again, there is a close link with the EURO-
Label and Telematic-platform projects. 
Terminals are in many cases the instruments to physically implement a service. The 
end-to-end compatibility of the terminal (for some basic services) in a multi-vendor 
environment (terminals are in competition) is a key objective. 
41 Analysis of EURO-ISDN terminal requirements in the context of market needs. 
42 Promotion of the availability of EURO-ISDN terminals. 
49. Promotion of the availability of EURO-ISDN terminals may for example include 
concertation with terminal manufactures, analysis' of the methods how to cut down 
the cost for the circuitry required for the construction of such terminals or 
definition of common promotion efforts for terminal availability. 
43 Development of 1-Stop shopping and billing principles for EURO-ISDN. 
-21-
1-Stop shopping and billing principles are recommended by the Council 24 in the 
context of Open Network Provision. 
In a first step, this latter project may start with 1-Stop ordering. 1-Stop ordering 
implies that the request/application for e.g. a service subscription across various 
networks can be made from one point.

3. THE CONTRIBUTION OF THE COMMUNITY: THE MULTI-ANNUAL ACTION 
TEN-ISDN 
3.1 INTRODUCTION 
50. The TEN-ISDN action aims to give a Community support for the execution of the 
projects of common interest identified in the "Series of guidelines" (Schéma 
Directeur), the adoption of which is proposed to the Council by means of the first 
decision submitted in Annex to this communication. These projects of common 
interest are classified according to the four broad lines of measures defined in the 
series of guide lines: 
Elimination of the bottle-necks in the deployment of the EURO-ISDN (action 
at the infrastructure level). 
To ensure end-to-end interoperability of telematic services. 
Migration of public and private applications towards the EURO-ISDN. 
Promotion of the availability of the EURO-ISDN terminals. 
51. Community support for the projects of common interest is carried out by means of 
feasibility studies which can include a validation phase. The execution of the 
projects is the responsibility of the sector actors, but it can be supported, when it is 
necessary, by interest subsidies or loan guarantees granted to the entities which 
carry out these projects. 
Moreover, specific actions aiming to ensure the interconnectivity of the networks 
and the interoperability of services and terminals, in particular in the field of the 
harmonization of standards, could be led in support for the implementation of all 
the projects of common interest. 
The interested actors by these actions are of three categories: 
- Those responsible for the implementation of the infrastructure EURO-ISDN, 
which are the public network operators. 
- Those likely to offer trans-European services on this infrastructure, who 
comprise the same public network operators and private service providers. 
- Those which put on the market telecommunication terminals, Le. the terminals 
manufacturers or importers. 
Given that differing regulatory regimes apply to these different actors, the methods 
and procedures applied for the Community projects will depend on the nature of 
the case. 
Envisaged changes in the regulatory regime (c/f. the Commission proposal to issue 
a Green paper on the infrastructure provision) which occur during the period of the 
execution of this Community-action, will be fully taken into account. 
-23-
3.2 SUPPORT FOR THE; PROJECTS OF COMMON INTÉRESt, 
32.1 THE FEASIBILITY STUDIES 
52. While due account will be taken of their infrastructural nature the projects of 
common interest have first to be the subject of careful definition and evaluation of 
their financial viability. This work will be carried out within the framework of 
feasibility studies, which can if necessary include a validation phase. They will be 
concentrated in the first years of the implementation of the programme. 
These feasibility studies will generally be financed at 100% by the Community, and 
will be carried out by contractors chosen within the framework of calls for tenders. 
322 FINANCIAL INCENTIVES FOR THE EXECUTION OF THE PROJECTS OF 
COMMON INTEREST 
53. The means specifically under consideration in the Community budget to support 
the execution of the projects of common interest are loan guarantees and interest 
subsidies. They can be supplemented by recourse to the temporary lending 
instrument and to the European investment funds decided by the European Council 
at Edinburgh. It is also possible to finance these needs by means of the ordinary 
loans of the BEI and, for the Objective 1 regions, by a contribution from the 
structural funds. Each one of these sources of finance has to be implemented within 
its own framework. 
54. With regard to the infrastructure as such, the implementation of the EURO-ISDN 
involves considerable investments, in the order of several tens of billion ECU. 
These investments in general are already programmed by the public networks 
operators, but the Annexes C and D show that in a number of fields, the calendars 
planned for the deployment of the EURO-ISDN are not in line with the target date 
end of 1994. The means of incentive available will mainly be used in this case to 
expedite the planned deployment. 
The entities eligible for this category of operations will be mainly the public 
network operators who 'are in charge of the implementation of the ISDN 
infrastructure. Given the high amount of investments to be supported, and the 
limited means available, the intervention of the Community will have to be carried 
out by judiciously proportioned recourse to the various sources, taking into account 
priorities and the specific situations of the public network operators. 
55. With regard to the aspects connected with the services (end-to-end interoperability 
and migration of the services towards the EURO-ISDN), the actions are led in a 
liberalized field, the interested entities being the public network operators and the 
private service providers. The projects identified in the feasibility studies will have 
to be carried out within a framework of calls for tender in order to determine the 
attribution of support in compliance with the Community rules. With regard to the 
implementation of migration possibilities of the services concerning the interchange 
of data between administrations, close coordination will have to be carried out with 
the TNA-IDA action. 
-24-
56. Lastly, concerning the terminals, mainly feasibility studies regarding needs of the 
market and promotion of the types of terminals corresponding to the criteria 
defined in the context of the trans-European networks are envisaged: recourse to 
interest subsidies and loan guarantees should not be frequent here. In this field 
where free competition has to be exerted, the measures taken will have to comply 
with the Community competition rules. 
3.23 IMPORTANCE OF TWO OF THE PROJECTS OF COMMON INTEREST: 
TELEMATIC PLATFORM AND EUROLABEL 
57. The projects on "telematic platform" and "EUROLABEL", which are the subject of 
the second broad line of measures and the objective of which is to ensure and 
maintain an essential character of a trans-European network, namely the full 
interoperability of the basic services, have a horizontal aspect which confers them a 
special importance. They will indeed ensure the coherence of the basic services and 
the underlying network. 
The common telematic platform will consist of a coherent architecture and common 
protocols as much as possible harmonized and re-used for a number of applications. 
The platform will be based on the existing results of standardization, supplemented 
by later work if necessary. This project will have to be coordinated with the 
architecture defined in the TNA-IDA action, as well as with those made at a later 
date for the broad-band ISDN. The construction of the telematic platform will 
require several feasibility studies, going from the definition phase to that of 
validation. 
58. The proposal for a EURO-LABEL aims at the promotion of the compatible end 
systems and at improving their visibility for the users. Technically, the EURO-
LABEL will encourage the verification of interoperability in a multi-vendor 
environment, thus contributing to the enhancement of competition. The 
development of the EURO-LABEL involves the collaboration of the public 
network operators, of the private service providers, of the terminal manufacturers, 
the test and user organisations (for example the "European ISDN User Forum"). 
Within the framework of a number of feasibility studies, these sector actors will 
have to define the concept of such a label jointly. It is envisaged that after a support 
effort limited to the launching of the system, it will be maintained of itself. 
33 MEASURES IN SUPPORT OF INTERCONNECnVITY AND 
INTEROPERABILITY 
59. The objective to achieve and maintain full interconnectivity of the networks 
implemented in the Member States and end-to-end compatibility of certain basic 
services will be supported by the Community action. 
60. While the advantages of interoperability are principally clear, it is still difficult to 
explain this concept to users and to market products which are interoperable (in a 
multi-vendor environment). Measures to raise the awareness are required. 
Moreover, in certain areas further standardisation work may be needed. This work 
will be mandated to the recognised standardisation organisations in Europe. 
-25-
61. Interoperability testing is an efficient way to verify whether products from different 
sources can interoperate. Further support in this respect for the basic telematic 
services is envisaged. 
It is noted, that some of the projects of common interest have a double nature, Le., 
they concern also this second level of Community action in support of 
interoperability. 
3.4 FINANCIAL ASPECTS 
62. The methods of the Community financial contribution, financing of the feasibility 
studies and incentives for the execution of the projects of common interest, are 
clarified as in points 3.2.1 and 3.2.2. 
The financial statement accompanying the draft decision gives an overall picture of 
the budgetary implications of this proposal for the 1993-1997 period. 
-26-
4. THE COORDINATION OF THE NATIONAL POLICIES 
4.1 GENERAL ASPECTS 
63. It is inherent to the approach of a policy which aims at coordination and 
harmonisation, to establish a close collaboration with the players involved. 
With the changes which have been introduced to the telecommunications sector in 
the Community, two main types of actors will be involved in the case of ISDN. 
64. Firstly, the Member States, which are responsible for the ISDN policy in their own 
territory and have in particular to ensure the required stability of regulatory 
environment for making available a public service offering on the entire territory, in 
correspondence with market needs. 
However, in view of the objective of European-wide harmonised introduction, a 
coordination of national policies has to be done at a European level 
*i •"' '• • 
The Community has already strongly promoted-the coordination of plans, 
promotion of awareness and support notably of standardisation efforts in its ISDN 
policy since 1984. This coordination has now to be strengthened. 
65. Secondly, the public network operators, which in all but one case are granted 
exclusive rights for the provision of the network infrastructure and today for the 
voice service, are responsible for the planning, financing and implementation of the 
infrastructure in such a framework. Account will be taken of any modification of the 
present regulatory regime. 
The Member States together with the public network operators will in particular 
have to make available all input data required to conduct the feasibility study 
related to infrastructure projects. 
Other sector actors, for example the manufacturing industry will be associated for 
projects related to the availability of EURO-ISDN terminals. 
As discussed in the present document, the specific Community action under the 
TEN framework would intensify and adapt this coordination role to the specific 
needs of the operation of the single market. 
Close cooperation between these actors is required. It is proposed to organize it in 
the framework of two groups: the TEN-ISDN Committee and the EURO-ISDN 
coordination platform. 
-27-
42. THE COMMITTEE TEN-ISDN 
66. A committee which will assist the Commission in the implementation of the 
Community action TEN-ISDN will be established. It will have a number of tasks: 
- It will examine the work programme of Feasibility Studies; 
It will be consulted on the definition of the projects and the allocation of 
support; 
It will assist in the establishment of evaluation criteria; 
It will examine the annual reports on the implementation of the series of 
guidelines and to discuss and propose possible amendments. 
The Committee will be composed of representatives from the Member States and 
the Commission. A representative of the Commission will chair committee 
meetings. 
If an updating of the guidelines appears necessary, the Commission plans to discuss 
this issue with the Member States in the framework of this Committee. The 
Committee may also be involved in the discussion of related matters, e.g. the 
question of the eligibility of actual proposals for projects of common interests. 
43. THE EURO-ISDN COORDINATION PLATFORM 
67. The TEN-ISDN coordination platform will allow to bring together the relevant 
sector actors, network operators, service providers, manufacturers, test houses, etc. 
Representatives of the Member States authorities and from the Commission will 
assist 
Based on the experience of the WG TEN-ISDN, it is proposed that this 
coordination platform assumes the form of an informal series of meetings. The 
Commission will organise these meetings when necessary and will provide 
secretarial support. 
Principal task of this coordination platform is to discuss sector specific aspects of 
horizontal nature relevant to the implementation of the series of guidelines. It will 
form a suitable mechanism for the discussion of projects of common interest which 
may be forwarded on the basis of joint proposals of interested sector actors. The 
meetings will be open to all concerned sector actors. 
68. In order to ensure clear conditions and where required, a commercial framework 
for example for the submission of joint proposals or the definition of common 
architecture, sector actors may develop instruments like for example memoranda of 
understanding or European Economic Interest Groupings (EEIG) in the context of 
this action. 
The coordination platform will take particular account of user positions. Liaison 
with the European ISDN User Forum (EIUF)25 and other relevant user groups will 
be organized. 
25 EIUF is a user forum which was initiated by DG XIII of the CEC and which has the objective to identify 
user requirements related to the further shaping of EURO-ISDN. 
-28-
69. In addition, a relationship will be strengthened or established with other specialised 
organizations: 
• ETSI, which is the recognised standards organization responsible for ISDN 
standardization in Europe, and with which the Community has well established 
links; 
- the group IMIMG26, which involves 26 operators from 20 European countries; 
. ETNO27, with which the mutual interest of establishing a cooperation link will be 
explored.

5. COOPERATION WITH THIRD COUNTRIES. 
70. The nature of telecommunications in general and certainly the nature of ISDN is 
global 
International and regional standardization is a major prerequisite for the 
development of ISDN. 
Thanks to ETSI, Europe has a leading position in ISDN standardization. EURO-
ISDN will be implemented on ETSI standards (which are as far as possible in line 
with world wide standards). 
71. Some coordination for the introduction of EURO-ISDN exists in the form of the 
MoU group discussed in Chapter 1, which involves operators from all Member 
States of the Community, all EFTA countries (except Liechtenstein) and some 
other Western European countries. 
72. A closer cooperation of the Community with the EFTA countries and the other 
Western European countries for all coordination efforts for ISDN in Europe is 
required. 
A separate proposal will be prepared on the method and extension of such a 
coordination effort with third countries. 
-30-
6. THE REASONS OF THE COMMUNITY INTERVENTION IN THE FIELD OF 
THE ISDN 
73. The availability of a general switched network , allowing the offer of advanced 
services in telephony, image and data communication on a trans-European level, is 
an essential prerequisite, so that all economic operators, public or private, and in 
particular the SME's, can benefit to the maximum from the establishment of the 
single market, and the implementation of the four freedoms of movement. As 
shown in Chapter 1, the ISDN has the characteristics making it possible to give the 
type of advanced services necessary now for the actors carrying out an economic 
activity. 
74. The Community has implemented since 1984 a policy in support of the coordinated 
introduction of ISDN. On the basis of a Recommendation adopted by the Council 
in 1986, the Commission has regularly informed the Council and the European 
Parliament on the progress of the introduction of ISDN in the Community by 
annual reports. The communication of these reports gave rise to two Council 
Resolutions on ISDN, one in 1989 which aimed at the further strengthening of the 
coordinated introduction of ISDN in the Community, the other in June 1992 which 
stressed the importance of developing the ISDN as a trans-European network. 
Moreover, the Council adopted also in June 1992 a Recommendation on the 
application of the ONP to ISDN. 
Parallel to the continuation i of "these political developments, the Community 
supported, in particular financially, the work of the ETSI for the production of the 
standards defining a harmonized version of the ISDN (EURO-ISDN), the essential 
base to ensure the interoperability and the interconnectivity of the national ISDN 
implementations with the aim of making ISDN a genuine trans-European network. 
75. Since several years, the network operators of several Member States have started to 
provide ISDN services at a national level. The implementations present 
considerable differences from the point of view of the range of services offered, and 
also regarding the technical characteristics of accesses of those networks. This 
situation does not ensure the required degree of interoperability of the national 
network offerings. Aware of this situation, the public network operators concluded 
a "MoU" within the framework of which they commit themselves to implementing 
the EURO-ISDN: compatibility between the various networks and national services 
can indeed be obtained only if, in their implementation, harmonized standards are 
rigourously applied. 
One can therefore note that the elements for the deployment of a trans-European 
ISDN exist, and that the interest of such a type of development was recognized by 
the Council in 1992. Taking into account the progress of regulation in the 
Community, which prompts the actors of the sector to give new value added 
services, it is nevertheless not very likely that other actors than the public network 
operators, which have already begun large investment programmes, would 
introduce a generalized ISDN in the Community. If the commercial service of 
ISDN in the countries where a substantial offering already exists is not yet 
confirmed, demand develops nevertheless, and should increase when a 
homogeneous offer covering the entire Community, and more largely Europe, is 
available. 
-31-
76. The implementation of a voluntary approach based on the commitment of the 
sector actors as regards trans-European networks, such as it is envisaged in 
particular in the Title XII of the Treaty of the European Union, is necessary so that 
this general deployment is carried out quickly, in order to strengthen the 
competitiveness of the European companies and to provide the internal market 
with the means of effective communication which it needs already today. It arises 
indeed from the observation of the situation and from the discussions with the 
network operators that a number of reasons slow down the introduction of the 
EURO-ISDN: 
- the experience showed in the past that it was insufficient to rely only on the 
efforts carried out at the level of the Member States when wanting to arrive at 
the implementation of a general infrastructure according to a given timetable 
with the stimulant alone of the existence of a harmonized standard; 
- the MoU concluded between the public network operators excludes explicitly 
certain aspects, like the coordination of the introduction of basic services and 
the questions touching the terminals. But the field of the services and that of the 
terminals are particularly susceptible for incompatible developments: 
coordination at European level is necessary to obtain harmonized developments; 
- the field of responsibility of the public network operators covers in general the 
national level No mechanism ensures currently this responsibility across the 
Community, in particular with regard to the offer of basic telematic services. To 
allow the coordination of these lacking aspects - inter alia with the 1-Stop 
Shopping recommended by the Council? in the ONP measure on ISDN -, the 
4 creation of a telematic platform at a Community level is necessary; 
- all the measures have to be based on harmonized standards prepared by 
recognized standardization organizations. But collaboration can not be limited to 
the application of these standards only: practical questions connected with the 
introduction of the services: choices of the options, test conditions, measures 
aiming to ensure the interoperability, have also to be coordinated if one wants to 
introduce successfully a harmonized ISDN; 
- under the current conditions of regulation and vis-à-vis a demand which is not 
yet self-sustaining, the existence of incentives for investments can help to create 
a more rapid take-off of harmonized network and service supply; 
- finally, for the ISDN being a switched network for general use, which should 
allow two users wherever located in the Community to communicate, it is 
essential that this modern infrastructure is available in due time also in the less 
favoured peripheral areas. In the contrary case, this infrastructure would lose of 
the interest, even for the users of the central regions of the Community. The 
STAR programme has already contributed to the digitalization of the 
infrastructures of these regions. It would be appropriate that the measures taken 
in future with the aid of the structural funds take into account the 
implementation of the EURO-ISDN. 
- If the Community would remain inactive, it is believed that the LFR's will 
encounter a further widening of the gap in comparison to the status of advanced 
communications in the central regions. 
C'" '<-, 
-32-
77. The actions aiming to remedy the difficulties evoked above are of nature such as 
they have to be taken at the Community level or, still better, at European level. 
They will have to aim at the following three effects: 
- to accelerate the deployment of the EURO-ISDN and/or the adaption of 
existing offers to become EURO-ISDN conformant; 
• to encourage the coordinated introduction of harmonized basic services; 
- to adapt the offer of the EURO-ISDN to the specific needs resulting from 
operation of the internal market. 
78. The deployment of the ISDN as a trans-European network is justified by the 
contribution that it brings to the economic operators and to the administrations 
allowing to draw a maximum benefit from the establishment of the internal market 
and enabling the implementation of the four freedoms of movement. 
The above section details the reasons of technical nature for which a Community 
intervention is essential in this field. But this intervention is limited on the one hand 
to coordination tasks, on the other hand, when that appears suitable, to a certain 
stimulation of investments by the actors of the sector. 
79. The size of investments necessary for the deployment of a trans-European ISDN by 
implementing the EURO-ISDN is several tens of billion ECU: it is clear that these 
investments fall within the competence of the sector actors, mainly of the public 
network operators which have to finance this infrastructure. The appropriations to 
the Community budget to support this action account for less than 1% of these 
investments, which shows that they can only achieve an effect of coordination and 
of catalytic stimulation. 
It is therefore envisaged to target the use of the Community contribution to arrive 
at the achievement of objectives, the interest of which is recognized, and which 
would otherwise not be realised only by the actors of the sector in the Member 
States. This contribution will take all its effect insofar as it will make it possible to 
accelerate infrastructure investments envisaged in the field of the ISDN, and to 
guarantee the interconnectivity of the networks set up in the Member States. These 
investments, which can in addition enjoy the support of the various financial 
instruments of the Community, will to take part in the growth initiative decided in 
Edinburgh, and contribute to Community cohesion.

CONCLUSIONS 
80. In the past, telecommunications networks and services had often been developed at 
a national level, which had led to many incompatibilities and which has an 
aftermath until today. This endangers the competitiveness of European industry. 
Independent reports suggest that ISDN may be the opportunity for the Community 
to catch up this delay. 
Ideally, a fully fledged ISDN offering should be available with the completion of the 
single market. The current plans of the PNO's foresee, that the EURO-ISDN 
deployment will begin at the middle of the year 1993 and will extend over several 
years. 
81. On the basis of the Community's ISDN policy since 1984, the present 
Communication explains the interest to develop in the Community the ISDN as a 
trans-European network, and proposes a series of guidelines aiming at this 
objective as well as the Community contribution associated with this action. The 
proposal takes full account of the growth initiative decided by the Edinburgh 
Council 
A first decision is submitted for the adoption of these guidelines. It covers the 
objectives, priorities, the broad line of measures and the projects of common 
interest for the implementation of ISDN as a trans-European network. 
The second proposed decision concerns the Community contribution to the 
implementation of this trans-European network. It aims mainly to support this 
implementation by coordination work and, for a limited amount, by stimulation of 
the investments of the sector actors by means of interest subsidies and of loan 
guarantees. 
Moreover, it is requested from the Council to authorise the Commission to 
undertake exploratory discussions with the countries of EFTA and with other 
interested European countries, with a view to establishing if there is a mutual 
interest to cooperation in this field of the introduction of the EURO-ISDN.

Proposal for a 
COUNCIL DECISION 
on a series of guidelines for 
the development of ISDN as a 
trans-European network 
THE COUNCIL OF THE EUROPEAN COMMUNITIES, 
Having regard to the Treaty establishing the European Economic Community, and in 
particular Article 235 thereof; 
Having regard to the proposal from the Commission1; 
Having regard to the opinion of the European Parliament; 
Having regard to the opinion of the Economic and Social Committee; 
Whereas the internal market establishes an area without internal frontiers within which the 
free movement of goods, persons, services and capital must be guaranteed; whereas in 
order to ensure each of these freedoms the Community acts adopted or being adopted 
provide for measures involving substantial interchange of data between individuals, 
economic operators and the competent administrations; whereas such interchange can be 
ensured using trans-European networks; 
Whereas the aim of establishing trans-European networks is to allow of the circulation of 
information, with a view to enable the proper functioning of the internal market for all 
participants, in particular the small and medium sized enterprises in the Community; 
Whereas a trans-European ISDN will form a basic element of trans-European 
telecommunications networks; 
Whereas it is important, for the purpose of the internal market, to facilitate the movement 
of goods, services, persons and capital between the Community and non-Community 
countries, and more specifically the member countries of the European Free Trade 
Association; whereas this will lead to intensified trade relations between the economic 
operators of the countries concerned; whereas in turn this requires cooperation with those 
countries in order to promote European-wide connectivity and interoperability of ISDN; 
3S" 
Whereas appropriate Community action is needed to establish adequate coordination 
between the Member States and those responsible for laying the basic infrastructure, in 
order to ensure a harmonised introduction of ISDN services; whereas failure to adopt a 
Council Decision on the development of ISDN as a trans-European network would be 
liable to result in a lack of interconnection and interoperability between national networks 
and in a limited availability of compatible basic services; 
Whereas the only legal basis provided by the Treaty for adoption of this decision lies in 
Article 235;

telematics and other communications networks; 
Whereas ISDN is conceived as the general switched telecommunications network evolved 
out of the telephone network; 
Whereas the availability of a modern, general telecommunications infrastructure is an 
important factor to enable the economic actors to take full benefit from the market without 
internal frontiers; 
Whereas current implementations of ISDN have an insufficient degree of harmonisation, 
which hinders, for example, the free movement of ISDN terminal equipment; 
Whereas the availability of end-to-end compatible basic service (other than voice) is

European services, so as to reinforce the competitiveness of European industry; 
Whereas cooperation is also appropriate with non-Community countries in order to 
promote projects of common interest and to ensure interconnectiyity and interoperability 
of ISDN implementations; 
Whereas the Community consequently needs to establish a framework for the contribution 
of the Community to the implementation of ISDN as a trans-European network; whereas

Annex 
Definition of the TEN-ISDN Action 
1. The TEN-ISDN Action consists of the implementation of projects of common interest 
eligible under the series of guidelines defined in Council Decision [...] and measures 
ensuring interoperability. 
Three categories of action can be distinguished: 
projects of infrastructural nature; 
projects concerning telematic services and applications of trans-frontier nature; 
projects promoting the ISDN usage including promotion of ISDN terminal 
availability; 
measures concerning the end-to-end compatibility of a limited range of basic 
telematic services and corresponding terminal equipment; 
2. Projects of common interest can be supported by feasibility studies and by support for 
implementation. 
Feasibility studies for projects of common interest normally comprise the following 
phases: 
analysing the requirements (eg. bottle-necks); 
definition of the action; 
specification of technical requirements (in some cases); 
preparation of an action plan including the methods suited for implementation of 
the project; 
validation, on a small scale, of,the essential functions of the solutions adopted (in 
some cases); 
assessment of the results obtained. 
In addition to the feasibility studies there will be regular monitoring of the projects and 
measures undertaken in the context of this action. 
Community support for the implementation of projects of common interest may take 
in particular the form of interest rate subsidies and loan guarantees. 
HH 
3. The measures to ensure interoperability consist in: 
contribution to the development of prototypes and software functions; 
promotion of interoperable solutions specifically by the set up of a EURO-Label; 
interoperability testing; 
standardisation work; 
incorporating relevant R&D results notably from Community programmes; 
and the flanking measures: 
support for awareness for the notion interoperability; 
organisational support for the implementation of the above measures.

4. DESCRIPTION OF OPERATION 
4.1 Specific objectives of operation: 
- To carry out an operation representing the Community's contribution to the 
establishment and development of trans-European networks in the field of 
telecommunications, particularly with regard to the Integrated Services Digital 
Network (ISDN). 
The purpose of the operation is to contribute to the harmonized development of 
the abovementioned networks and to the availability of certain basic services 
throughout the Community in order to enable operators to participate fully in an 
internal market without frontiers. 
A second part of the Community activity is intended to assist the interconnection 
of such networks and interoperability of these basic services which are accessible 
via such networks. It consists in defining, for each area, a master plan of the 
trans-European network (such a plan already exists for ISDN) and then to 
implement the Community's contribution to the establishment of this network, 
while coordinating the activities contributing to this operation in the Member 
States, which will be called upon to provide the bulk of the necessary investment 
to those involved in this operation, consistent with the principle of subsidiarity. 
- The Community contribution will chiefly be in the form of feasibility studies 
leading to a precise definition of projects of joint interest, and subsequently in 
the form of interest rebates and loan guarantees granted to those involved to 
carry out such projects. The Community contribution covers projects of joint 
interest and activities to promote interconnection of networks and 
interoperability of basic services. 
- Given the scale of the investment required for the setting up of a general 
infrastructure and in view of the forms of support being considered, the 
Community contribution can only have a stimulating effect which will 
supplement the efforts being made at national level. 
- Although a relatively small percentage, the Community contribution is 
necessary, since without it there is an obvious danger of insufficient 
harmonization and delay in deployment. 
4.2 Duration: 1993-1997 
4.3 Target population: public network operators, providers of telecommunications 
services, systems and software manufacturers, users. 
5. CLASSIFICATION OF EXPENDITURE OR REVENUE 
5.1 Non-compulsory expenditure 
5.2 Differentiated appropriations 
5.3 Type of revenue involved: not applicable 
6. TYPE OF EXPENDITURE OR REVENUE

implementing the work programme will be wholly financed; the studies will be 
approved according to the standard Commission procedures (invitation to tender, 
CCPC). 
6.2 Subsidy for joint financing with other sources in the public and/or private sector: 
- Generally none 
6.3 Interest subsidy: 
- Interest subsidies may be granted to those involved in the sector taking part in 
the implementation of projects of common interest. 
6.4 Other: 
- Provision has also been made for loan guarantees. 
- Assistance will be sought from other Community financial instruments (i.e. the 
Structural Funds, temporary loan instrument, etc.). 
6.5 Should the operation prove an economic success, is there provision for all or part of 
the Community contribution to be reimbursed?: No. 
6.6 Will the proposed operation cause any change in the level of revenue? No. 
7. FINANCIAL IMPACT 
7.1 Method of calculating the total cost of the operation for the 1994 financial year: 
In 1994 ECU 5 million will be earmarked for feasibility studies, with an average of 
ECU 500 000 per study in the field of ISDN (ECU 5 million). In addition, for 
ISDN, ECU 5 million has to be set aside to finance interest subsidies.

8. WHAT ANTI-FRAUD MEASURES ARE PLANNED IN THE PROPOSAL FOR THE 
OPERATION? 
The relevant Commission departments will verify the proper implementation of the 
feasibility studies prior to payment, taking into account contractual obligations and 
principles of good management. 
In conjunction with the relevant Commission departments suitable audit methods will be 
devised to deal with interest subsidies and loan guarantees. 
9. ELEMENTS OF COST-EFFECTIVENESS ANALYSIS 
9.1 Objectives 
The aim of this operation is to encourage those involved in this sector in their 
efforts to achieve interoperability and interconnection of national ISDN networks. 
The aim of the Community contribution is to stimulate investment in these sectors 
of the order of billions of ecus in the medium term. However, in 1993 and 1994 
the operation will concentrate mainly on carrying out feasibility studies for projects 
of common interest which, when implemented in subsequent years, should generate 
the necessary investment. 
The operation is divided into two parts. The first concerns support activities for 
projects of common interest and its aim is the rapid and harmonized establishment 
of the infrastructure and basic services. The second part relates to horizontal 
activities, including support for interconnection of networks and interoperability of 
basic services. 
9.2 Grounds for the operation 
The purpose of this operation is to endow the Community with the modern means of 
communciation which are essential to its economic development. Availability of 
advanced telecommunications networks in this particular field, involving 
multipurpose networks, is essential if operators are to take advantage of the 
opportunities to expand their activities, the economies of scale provided by the large 
Community market and the free movement of goods, persons, services and capital. 
Small businesses in particular (of which there are some ten million in the 
Community), whose key role in economic growth is acknowledged, are dependent 
on the availability of a universal infrastructure. 
Given that the services market is competitive (except for telephone services at the 
present time), a non-regulatory approach is indicated. 
Experience of recent years has shown that in the absence of any mechanism in this 
area at European level to ensure harmonized development, particularly of certain 
basic services, Community action is necessary. In order to promote such 
coordination at European level, Community financing must also be made available. 
This Community support will be for a limited period and will be provided at the 
early stages to get the mechanism off to a good start. Furthermore, a financial 
contribution for the development of less-favoured regions is consistent with the aims 
of this operation. 
Should these measures not be taken in good time, the development of ISDN in the 
Member States might be less effective because it would not be in general use and 
the basic services would not be compatible. In every case, experience has shown 
that taking action after the event to rectify the lack of harmonization in such a 
development would prove more costly. 
So 
Proper coordination between the Member States, which is intrinsic to Community 
action, is necessary in order to ensure consistency between what is being done at 
national level and Community action. The principle of subsidiarity applies fully in 
this case. 
9.3 Monitoring and evaluation of the operation. 
Each feasibility study must state its exact objectives and define specific projects. 
The effectiveness of the operation will ultimately be judged by the amount of 
investment forthcoming from those involved in the sector. 
All operations will be evaluated on an annual basis (report). The assessment will be 
based on objective criteria which will be drawn up by a committee monitoring the 
implementation of the operation. 
Moreover, the introduction of RNIS in the Member States of the Community is the 
subject of an annual report established by the Commission, based on the Council 
Recommendation of 22 December 1986. 
9.4 Consistency with financial planning 
Provision for this operation has been made in the multiannual financial programme 
under the heading Trans-European Networks. 
10. ADMINISTRATIVE EXPENDITURE (PART A OF THE BUDGET) 
10.1 Will the proposed operation call for additional Commission staff? If so, how many? 
Yes. The first stage will be to launch feasibility studies, at a preparatory level, in 
1993, and then on a full scale in 1994. Assuming that ten or so studies will be 
carried out for ISDN, approximately eight staff (four A, one B and three C) will be 
necessary for management as of 1994. In addition, coordination between Member 
States and financial engineering (setting up of interest subsidy and loan guarantee 
operations) will call for a further three staff (one A, one B and one C). Overall, 
five staff (two A, one B, two C) should be Commission officials, with the 
remainder being employed on a non statutory basis. 
Total: Four A, two B and four C. 
10.2 Indicate the amount of staff and administrative expenditure involved in the proposed 
operation. 
In the light of what has been said under 10.1, six category A staff will have to be 
provided in die form of seconded national officials or experts and three category C 
staff as temporary secretaries. 
Committee meetings: Some five meetings a year of the Consultative Committee, 
plus 40 or so meetings of groups specific to the projects, at a cost of ECU 12 000 
per meeting, will require a meetings budget of ECU 500 000 (A 250/251). 
Missions: ECU 75 000 (A 1300)

NOTE TO THE COMMISSION FROM V.-P. M. BANGEMANN; 
IN ASSOCIATION WITH COMMISSIONER VANNI D'ARCHIRAFI) 
Trans-European Telecommunications networks (TEN) 
1. The introduction of the concept of trans-European networks in Tide XII of the Treaty on 
the European Union has led to the identification of three priorities for the application of 
this concept in the sector of telecommunications: 
TEN-TNA: Telematic Networks between Administrations; the necessity of which is 
directly derived from the needs of the single market; 
TEN-ISDN: Integrated Services Digital Network; evolving out of the current 
telephone network. Since 1986, the year of the first Council Recommendation 
concerning this type of network, the harmonised introduction of ISDN based on 
European standards was promoted at the level of the Community; 
TEN-IBC: Integrated Broadband Communications; for which the Community's RACE 
programme has established the functional specifications and has laid the technology 
base for a European wide introduction. 
In these three priority areas, the methodology of the said Tide XII is used, which foresees 
to define: 
a series of guide-lines (schéma directeur) and 
a possible Community contribution for the implementation of the fixed objectives. 
2. The proposals concerning TEN-TNA1 have already been adopted by the Commission. 
Now, proposals for the two other priority areas are submitted. 
TEN-Intcrchangc of Data between Administrations; adopted on 15.03.1993; COM(93) 69 final; 
S Z-
3. Concerning TEN-ISDN die following documents are introduced: 
a draft Communication to the Council and the EP; 
a proposal for a Council Decision concerning the Schéma Directeur and 
a second proposal for a Council Decision defining the envisaged Community 
contribution to the implementation of the Schéma Directeur 
This latter proposal is accompanied by a Financial Statement. 
Both proposals for Council Decisions are for the time being based on Article 235. 
4. ISDN is a general, multi-purpose network integrating a large variety of voice, data and 
images services via a single network access. 
While in six Member States commercial ISDN offerings exist, in the other half of the 
Member States only pilot implementations are available at current. Moreover, the existing 
commercial ISDN implementations are not yet harmonised to the required extent which 
leads to problems notably with regard to the European-wide provision of basic services 
(apart from telephony, those services are by and large missing or have technical problems) 
and with regard to terminals, which cannot be interchanged freely owing to technical 
differences and hence, the free circulation of ISDN terminals is considerably hindered. 
5. The transition and migration towards the EURO-ISDN which is fully based on harmonised 
European standards, is the main thrust of the proposed Community action. Taking account 
of a Memorandum of Understanding (MoU) in which 26 (western) European public 
network operators have committed themselves to introduce EURO-ISDN, the proposed 
Community action foresees complementary measures aiming: 
to accelerate the roll out of EURO-ISDN; 
to remedy the bottle-necks (eg. the one's mentioned above) and 
thus, contribute to improved interconnectivity of the infrastructure and 
interoperability of the basic services. 
The investments required for a general deployment of EURO-ISDN are estimated at some 
tens of BECU and are to be financed by the public network operators. Over the period 
1993-97 the budget for the proposed Community contribution foresees 90 MECU. The 
eventual financial support of the Community can thus only be of the nature of incentives 
and will use the means indicated in Tide XII. 
7. Integrated Broadband Communications can be described as the next major step of 
technological innovation of the general switched telecommunications infrastructure, after 
ISDN. IBC includes the capabilities for very high speed data transmission, for the 
transmission of high definition images and advanced multimedia applications. 
S3 
While commercial ISDN offerings have started already in the late 80*s and the target date 
for a general availability of EURO-ISDN is agreed for end 1994, a general commercial 
introduction of IBC will start after 1995. Notwithstanding this, increasingly elements of 
IBC technology are being introduced (eg. optical fibre, notably in the backbone of the 
switched network) already now. Other elements (eg. ATM2 technology) are the subject of 
major trials in the course of the coming years. As for ISDN, also for IBC, the 
development of some basic service is crucial. 
Regarding IBC services, the definition, technical development and practical 
experimentation with such services is required in the next years. 
8. The overall time frame for the proposed Community action TEN-IBC is identical to the 
one for ISDN (93 - 97). Given the different status of ISDN on one hand and IBC on the 
other hand Cm terms of the technology and the timing of the introduction) the approach 
and the nature of the proposed Community action TEN-IBC will (partially) differ from 
TEN-ISDN. A full scale introduction of the IBC network may well extend into the next 
millenium . 
Regarding the approach for TEN-IBC, it is proposed to start with a preparatory action, 
which will be carried out during the following 24 months. 
To this end two documents have been elaborated: 
a proposal for a Commission Decision regarding the envisaged preparatory action 
TEN-IBC and 
a draft Communication informing the Council and the EP on this approach. 
9. For the action TEN-IBC, the budget planning for the period 1993-97 foresees an amount 
of 95 MECU. The investment for the network deployment will be in the order of 20 - 40 
BECU over the next ten years. Again as for ISDN, this will come onto the charge of the 
public network operators. The proposed Community financial support will only be a minor 
stimulation. 
10. Both types of networks have the nature of a general infrastructure, which implies that a 
full geographical penetration (this is the defined policy objective) will extend over more 
than a decade. Also in view of the current regulatory regime and the planned further 
liberalisation, the basic problem is the creation of a "critical mass" so that a stage of self-
contained demand is reached. The proposed Community actions aim precisely at the 
support of mis initial phase. 
11. The general availability of a modern telecommunications infrastructure will notably be for 
the benefit of many SME's. While large cooperate users can afford dedicated solutions, 
SME's typically depend on die general infrastructure. 
Asynchronous Transfer Mode, a switching technology used for IBC 
SH 
Moreover, a modern telecommunications infrastructure will also contribute to an improved 
functioning of the single market, given the increasing trans-frontier communications needs 
which will arise for the participants of that market. 
12. Owing to the infrastructural nature of both networks, measures in support of them will 
furthermore have a possible impact in the context of the growth initiative. 
Firstly, it can be expected that the enormous investments will have a direct impact on the 
employment. 
Beyond this direct effect, the availability of a modem communications infrastructure is a 
crucial factor for the competitiveness of the European countries as a location for 
entrepreneurial activities, since the cost of communications presents an increasingly 
important cost factor for enterprises in general. 
13. With respect to social and economic cohesion, the trans-European telecommunications 
networks have a two-pronged role to play: 
the geographical coverage of the peripheral regions of the Community will allow to 
the users and in particular to the SME's to benefit from advanced services which is 
crucial for an efficient operation of their activities; 
they can become an essential factor concerning the cooperation of the central and 
peripheral regions of the Community, thus favouring the development of a truly 
harmonised single market. 
14. Finally, reference to similar efforts in the U.S. (Al Gore initiative) and the law on the 
enhancement of the telecommunications infrastructure in Japan is made. Europe has to 
watch not to fall behind those two regions in yet another key high technology domain. 
CONCLUSIONS 
15. In the field of telecommunications the Commission has worked out clear proposals 
regarding TEN-ISDN and TEN-IBC. Those proposals are based on a close collaboration 
with the main sector actors concerned and are supported by them. 
In view of the importance of these proposals in the context of the growth initiative, for the 
social and economic cohesion and for the competitiveness of Europe, a rapid adoption of 
the proposals would help considerably to achieve the objectives and to realise that the full 
potential benefits can be developed. 
The agreement of the Collège to the proposed documents TEN-ISDN and TEN-IBC is 
requested.

SECTION 1 INTRODUCTION ANNEX A 
ISDN (Integrated Services Digital Network) is an acronym describing the provision of a wide range of existing 
and new telecommunications services over digital networks, making them available to customers through a 
standardised single access point. 
ISDN removes the barriers between speech, data, text and video services, integrating them into a single digital 
telecommunications network. The provision of end-to-end digital connectivity guarantees high-quality network 
performance to customers. 
ISDN provides significant benefits to the customer in terms of availability of services and usage flexibility. Cost 
effectiveness due to more efficient utilisation of telecommunications facilities arc an added benefit from a 
customer's point of view. 
ISDN offers a range of services particularly suitable for emerging new (customer) applications. In particular the 
business worid can benefit from the increased speed of ISDN connectivity and conformity to international 
standards. 
Conformity to international standards will guarantee die use of compatible equipment and terminals and make 
international interconnection possible in an easy and economical matter. 
The introduction of ISDN is carried out in such a way as to ensure that it coexists and interworks with existing 
dedicated networks, and that ISDN terminals will communicate with non-ISDN terminals. 
ISDN can therefore be seen as a most attractive and powerful tool available to the business community worldwide. 
SECTION 2 TERMS AND DEFINITIONS 
This section provides definitions for a number of terms used in section 3. 
ISDN = Integrated Services Digital Network 
PSTN = Public Switched Telephone Network 
PSPDN = Packet Switched Public Data Network 
CHANNELS 
Two types of channel arc defined in the ISDN: 
a) The B-channcl is a communication channel used to support the transmission of voice data or image with a 
capacity of 64 kbil/s. 
b) The D-channel is a signalling channel used for the establishment of B-channel links. The D-channel can also 
be used for the transmission of user data. 
ACCESS TO THE NETWORK 
There are two types of access to the ISDN network: 
a) Basic access with two B-channels and one D-channel of 16 kbit/s. It can support up to eight terminal devices. 
Therefore it is suitable for small business units and the residential market (see Figure 1).

Note: the wiring is not considered in this figure. 
TYPES OF INTERFACE (or REFERENCE POINTS) 
Interfaces are defined us the points at which dissimilar (or similar) equipment or functions are interconnected. 
In ISDN different reference points are defined. For the user, these reference points are the S and T interlaces in 
the case where ISDN terminal equipment is used. This eliminates the need for equipment such a^ modems and key 
^ei controllers. 
TERMS AND DEFINITIONS (continued) 
It is possible to connect non-ISDN terminals to the ISDN network using terminal adapters. In this case the interface 
for the user is the R interface (sec Figure 3). 
Figure 3: Types of user interface

NT 2 s Switdhing Equipmant. ie. ISPBX (OTE) 
R = Interface between a non-ISDN terminal and the terminal adapter. 
S = Interface between an ISDN device and the network termination. 
T = Interface between an ISDN network termination and the network. 
In the case of an ISDN non-swiiching device the S and T interfaces are the same. 
NT = Represents the physical point at which the ISDN configuration on the user's premises connects to the 
network. 
TERMS AND DEFINITIONS (continued) r 
ISDN SERVICES 
ISDN services are divided into two main categories (sec Figure 4). 
a) Bearer services 
These arc transport services where the information delivered by the network is transferred without alteration or 
addition. Issues related to format or presentation of information are not predefined. In other words, the information 
is transported between network terminations (NT) in a transparent mode. 
b) Teleservices 
A teleservice is a service as defined by the terminal equipment functionality. A teleservice always uses a bearer 
service. When a user selects a teleservice the network will provide the appropriate bearer service.

6 TERMS AND DEFINITIONS (continued) 
Supplementary services 
Supplementary services arc additional facilities offered by the ISDN network in conjunction wiih cither bearer or 
tclcscrviccs. Consequently they cannot be offered to a user as stand-alone services. Some supplementary services 
in the ISDN arc suitable for non-voice communication and some only suitable for voice communication. It is up 
to the user to choose the appropriate set of supplementary services to suit the application in question (sec Figure 5).

TERMS AND DEFINITIONS (continued) 3-
Inter/working 
ISDN users can communicate with users of other existing networks, e.g. the Public Switched Telephone Network, 
the Packet Switched Public Data Network, etc. through interworking functions provided by the network. 
Intercommunication 
Non-ISDN terminal equipment can be connected to the ISDN by means of a terminal adapter and may intercommu­
nicate with compatible terminals connected to existing networks. In this case, the user has to select the appropriate 
bearer service, e.g. Telefax Group 3. On the terminal adapter he then selects the 64 kbit/s bearer service usable 
for 3.1 kHz audio information transfer (see Figure 6).

Communication modes 
ISDN offers two communication modes, circuit mode and packet mode. The services offered on the B-channcl are 
in circuit mode (one channel allocated for each communication). Packet services are offered on the D-channel 
(several communications on the some physical circuit). They can also be offered over a B-channcl using packet 
handling interfaces (see Figure 8).

Tabic 1: Scope of EURO-ISDN 
Remarks: 
The notion EURO-ISDN refers to the implementation of ISDN as it is described in a 
memorandum of understanding from April 1989, signed by 26 public network operators from 
20 European countries. 
The implementation of EURO-ISDN will be based on harmonised standards prepared by ETSI 
which are summarised in the ETSI Technical Report No. 10 (ETR 10); ETR 10 can be 
obtained from the ETSI Secretariat.

ANNEX C Summary of Euro ISDN availability 

NOTES ON MAPS AND TABLES: 
1) The % of territorial coverage of EURO-ISDN is defined in this context 
as: areas ( of an administrative region) where BRI. fully conformant with 
ETS 300.153, and PRI fully conformant with ETS 300.156, are available. 
This means that existing national ISDN offerings, where the user network 
interfaces are not fully in line with these ETSs, are no±_considered here. 
2) The definition of "coverage is: The % of an administrative region where 
EURO-ISDN is available, at year end, either by direct connection to a local 
switch which is equipped with EURO-ISDN BRI or PRI, or where a local 
network area has access to EURO-ISDN BRI and PRI by means of remote 
access (if offered on a regular basis). 
3) As each country is organised somewhat differently, and information 
was not always presented in the same manner, for the determination of an 
appropriate scale or granularity the editors have had to scale the 
percentages rather broadly. 
4) As each country provided information in a slightly different manner, 
the shadings are map specific.
