Taking account of the differences between existing national procedures, Member States shall take the necessary steps to ensure that reference is made to: European standards and European prestandards as described in Article 2 (b); international standards when accepted in the country of the contracting authority; in public procurement orders relating to information technology so that these standards are used as the basis for the exchange of information and data for systems interoperability. 2. In order to provide end-to-end compatibility, Member States shall take the necessary steps to ensure that their telecommunications administrations use functional specifications for the means of access to their public telecommunication networks for those services specifically intended for exchange of information and data between information technology systems which themselves use the standards mentioned in paragraph 1.
