Describes flexible access networks using optical fibre technology based on ITU-T Rec. G.983.1. Describes the functions that extend ITU-T Rec. G.983.1 to enable survivability-protection enhancements for the delivery of highly reliable services. Describes B-PON survivability architectures, protection performance criteria, and protection-switching criteria and protocols.
