3. ETSI Technical Specification
Aim:
To provide basic set of principles that should be adhered to in order to maximise potential benefits from publicly available ENUM implementations within Europe
“Efforts at drawing together a a co-ordinated approach should not only result in a firm foundation for ENUM activities within the European environment but should also assist in enhancing the competitive communications environment”
The importance of gaining the support or all relevant parties was recognised as a prime requirement

4. Some emerging principles within Europe from ETSI
E.164 integrity must be maintained
Compliance with Data Protection Directives
Adherence to ITU Recommendations and IETF Specifications
Compliance with National Regulatory requirements
Must facilitate a competitive environment
Must be user ‘Opt in’
Existing network functions must not be compromised e.g. Number Portability, Carrier Selection
All provide good safeguards

5. Major Issues of concern
Provisioning based on false information by users
Authentication and validation requirements
Abuse of data stored
Regulatory requirements
Alternative ENUM implementations

6. What still needs to be done?
Administrations must be encouraged to actively consider national implementation aspects
The ETSI Framework document needs to be completed and formally agreed
Issues surrounding the choice of gTLD must be resolved
All effort must be put into completion of the ITU studies to facilitate the insertion of Country Codes within the DNS
