This Recommendation describes the extended functions for B-PON systems defined in ITU-T Rec. G.983.1 to enable protection functions. It is based on Appendix IV/G.983.1. In particular, it focuses on the protection-configuration types B and C described in that appendix.

This Recommendation discusses a number of protection feature and function choices and provides the necessary specifications in the PON layer to implement these choices. These include guidelines on performance objectives (for example, switching and detection time), application functionality (for example, revertive mode, non-revertive mode, extra traffic support, automatic switching, and forced switching), switching criteria and switching protocols (1+1, 1:1, 1:N, bidirectional and unidirectional mechanisms).

This Recommendation considers protection enhancements for the delivery of highly reliable services for a variety of B-PON network scenarios, including Fibre to the Cabinet (FTTCab) and Fibre to the Office (FTTO).
