The OptiX OSN 6800 supports the following two types of electrical cross-connections:
The OptiX OSN 6800 NEs of different versions deal with the electrical cross-connections in different ways.
V100R001 and V100R002: The OptiX OSN 6800 of these two versions preferentially uses centralized cross-connections for electrical cross-connections. (The equipment automatically selects the centralized cross-connections if a logical centralized cross-connect board is available).
V100R003: The OptiX OSN 6800 of this version preferentially uses distributed cross-connections for electrical cross-connections.
After being configured, the centralized and distributed cross-connections cannot be switched over.
This is a specification of the versions. The preference cannot be configured. Understanding the specification helps you to locate a possible fault.
