Fiber connection between ports when the client-side 1+1 protection is configured for a DCP board on 1600G devices

4

The TI1 and RO1 ports on the DCP board are interconnected with client-side devices. The TO11 and RI11 ports need to be connected to the client side of the active ELOG board, and the TO12 and RI12 ports need to be connected to the client side of the standby ELOG board.

Whether the intra-board 1+1 protection on the DCP board supports the revertive mode
No, it does not.

Whether two LSX boards are required for configuring client 1+1 protection
Services need to be dually fed, and therefore two LSX boards are required.

Method used to specify the working and protection trails of an intra-board 1+1 protection group on DCP boards
Select ports 1(RI11/TO11) and 2(RI12/TO12) of the DCP boards as the working and protection trails respectively. Alternatively, select ports 3(RI21/TO21) and 4(RI22/TO22) of the DCP boards as the working and protection trails respectively.

OLP/DCP board alarms that can trigger intra-board 1+1 protection switching
OLP or DCP boards support the function of dual feeding and selective receiving. They can work with OTU or line boards that do not support this function to configure intra-board 1+1 protection. An R_LOS or POWER_DIFF_OVER alarm reported by an OLP or DCP board can trigger intra-board 1+1 protection switching.
