Introduction to Intra-Board 1+1 Protection

The intra-board 1+1 protection utilizes the dual fed and selective receiving function of the OTU, OLP, or DCP board and diverse routing scheme to protect the service.

The intra-board 1+1 protection complies with the following standards or protocols:

ITU-T Recommendation G.798 (Characteristics of optical transport network hierarchy equipment functional blocks)
ITU-T Recommendation G.808.1 (The generic functional models, characteristics and processes associated with various linear protection schemes for connection-oriented layer networks)
