The OptiX OSN 6800 adopts two inter-board communication modes, that is, Ethernet and RS485. What information is transmitted in these two modes?
1. For a single subrack:
A. RS485: Both the protection switching information about various protection groups and the information about the ASON software are transmitted over the RS485 bus by default.
B. Ethernet: Except the information carried over the RS485 bus, all the other information are carried over the Ethernet, such as information about reported alarms and delivered configuration.
2. For the main-extended subrack (multiple subrack):
All exchanged information between the main subrack and extended subrack is transmitted over Ethernet. This is called inter-subrack information exchange.
