Relationship between bit errors of a tributary board and those of an optical board

Relationship between bit errors of a tributary board and those of an optical board:
1. As the tributary board detects signals from a cross-connect board, if bit errors occur on the optical board, they will also occur on the tributary board.
2. If the optical board has no bit errors, bit errors may occur on the tributary board due to faults of the tributary board or cross-connect board.
3. If the tributary board has no bit errors, the optical board is normal and has no bit errors either.
