Latest news

The ECC Plenary in its meeting in Montpellier 1-5 March 2010 decided to merge the WG NNA and the ECC PT2 TRIS. At the joint meeting of WG NNA and PT TRIS in Vilnius 16 June 2010 it was decided that the name of the new group is Working Group Numbering and Networks (WG NaN).

The objectives of WG NaN PT TRIS are to:

  • Advise the ECC on network technology, especially in relation to identifying where technology developments will effect the regulation of network access, interconnection, and interoperability
  • Identify specific network related problems and advise the ECC on what European harmonisation procedures which may be needed to avoid proliferation of diverse national solutions
  • Discourage market distortion and technical barriers to market entry through appropriate application of harmonised measures
