Summary

This Recommendation describes the optical network terminal management and control interface (OMCI) specifications for broadband passive optical networks (B-PONs). In order to provide support for protected B-PON systems specified in ITU-T  Rec. G.983.5 "A broadband optical access system with enhanced survivability," additional OMCI specifications are required. This Recommendation describes the enhanced OMCI specifications for a B-PON system with protection features. The enhancements described include the addition of protection-related attributes to existing managed entities, managed entity relations diagrams for protected systems, and detailed scenarios for OMCI start-up/tear-down/switch-over and for virtual path (VP) configuration/removal in protected B-PON systems.
