Annex 1  Example of a connection, path, link, hop
Annex 2   Error performance events for different SDH fixed wireless link configurations
 1     Introduction
 2     Link end-points are path end-points with and without frequency diversity
 3     Link end-points are SDH multiplex section end-points
        3.1     One hop multiplex section without frequency diversity protection
        3.2     One hop multiplex section with frequency diversity protection
 4     Link end-points are SDH regenerator section (RS) end-points
        4.1     One hop RS without frequency diversity protection
        4.2     RS with frequency diversity protection switching
        4.3     Multi-hop RS without frequency diversity protection
 5     Link end-points are combinations from the previous ones
