The former filed a complaint with the Commission's Directorate General for competition in April 1995 after several unsucessful attempts to obtain a licence for a broadband telecommunications network based on SDH (Synchronous digital hierarchy) technology, which would allow the transfer of data between 36 different sites of the German public television broadcaster ARD.

Under Directive 92/44/EEC, Member States must ensure that the telecommunications organizations make available certain types of leased lines to all providers of telecommunications services. However, the Directive provides only for such offer of a harmonized set of leased lines up to a certain bandwidth. Companies needing a higher bandwidth to provide services based on new high-speed technologies such as SDH (synchronous digital hierarchy) have complained that the telecommunications organizations concerned are unable to meet their demand whilst it could be met by the optic fibre networks of other potential providers of telecommunications i ...[+++]nfrastructure, in the absence of the current exclusive rights. Consequently, the maintenance of these rights delays the emergence of new advanced telecommunications services and therefore restricts technical progress at the expense of the users contrary to Article 90 (1) of the Treaty, in conjunction with point (b) of the second paragraph of Article 86 of the Treaty.
