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
