of CEPT, and they must have strong interests in ensuring integration
of the European network infrastructure, interoperability
of services across Europe and commit themselves to support
advanced collaborative research and development activities.
Most of the members belong to the category of “old” public network
operators, however, newcomers like Mercury, UK have
joined.
The European PNOs which are currently members of
EURESCOM are shown in Table 1.
Results achieved
Since EURESCOM was established three work programmes
have been launched resulting in about 50 projects. Although
EURESCOM is still in the initial phase, the majority of these
projects have brought significant results giving the owners valuable
input to their development of European services and networks.
The work programme is grouped into six work areas:
1 Strategic studies
2 Infrastructure and switched networks
3 Intelligent networks
4 Telecommunications Management Networks
5 Telecommunication services
6 Software requirements and practices
In the following we will highlight important results.
In the work area of telecommunication services major
achievements are:
- Specification of a multimedia retrieval service, including the
supporting network capabilities and terminal requirements
- An overview of the authentication methods applied in
telecommunications, analysis of the pros and cons of these,
and a guide for developers of services that need authentication
- Scenarios for the construction and exploitation of a pan-European
directory service based on the X.500 recommendation.
In the area of Intelligent Networks (IN) the following achievements
have been made:
- Specification of a pan-European Virtual Private Network
(VPN) service
- Specification of a pre-Universal Personal Telecommunication
(UPT) service
- Contribution to the definition of pan-European IN services
- Contributions to the development of future IN architectures.
In the Telecommunications Management Network (TMN) work
area:
- TMN organisational model
- Management services definition and evolution
- TMN security requirements
- Contributions to the development of the TMN X-interface for
the management of transmission and signalling systems.
The infrastructures and switched networks work area includes
results as follows:
- Specifications of a pan-European Asynchronous Transfer
Mode (ATM) Virtual Path handling system, intended for use
by the ATM Pilot Group
- Technical recommendations for the METRAN Project, suggested
for application during the METRAN implementation
phase
- Specification of Abstract Test Suites for ISDN end-to-end
testing, to be used not only by EURESCOM shareholder/parties,
but possibly by manufacturers and non-European PNOs
as well
- Exploration of optical network issues and reliability of existing
and future optical networks.
Concerning the area of Software requirements and practices,
two fact finding studies have been carried out:
- Common software practices, which concludes that
EURESCOM must concentrate on areas where the PNOs can
