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
