     Further plans
     - Further introduce eDCO and eROADM
     - Increase fiber resilience in last mile

     -   Multi-domain control plane interworking (DRAC)
     -   Test new technology, e.g. PBB-TE
     -   Further enhance monitoring and reporting
     -   Continue on tools development, e.g. TL1 Toolkit
         and NDL developments
