Whether an SC2 board can concurrently process OSC signals and ESC signals


Processing for OSC signals is different from that for ESC signals.
An SC2 board concurrently processes two OSC signals of different directions, transits and exacts the system overhead, and sends the signals to the SCC board. OSC signals occupy a dedicated wavelength for transmitting monitoring and OAM information.
Transmission of ESC signals does not require dedicated monitoring units such as SC2. The ESC signals and service information are carried over the same wavelength, which does not require extra wavelength resources.

The MCA4 board uses a 1 x 4 optical switch, and therefore can monitor the information about one signal, including the wavelength information, optical power, and OSNR.

Signal flow of SC2 boards for OptiX BWS 320G
The optical signals input to the RM1 and RM2 ports of the SC2 board are sent from the RM port of the SCA board. The optical signals output from the TM1 and TM2 ports of the SC2 board are sent to the TM port of the SCA board.

Whether the optical supervisory channel (OSC) mode and the electrical supervisory channel (ESC) mode of OSN 8800 devices can be used together
You are not advised to use the OSC and ESC modes together. You can disable the ESC mode through the GCC0 channel on an optical board.

Whether optical signals of the SC2 board are originated from multiplexed signals or received by the SC2 board
The OSC signals received by the SC2 board are sent from the laser of the peer SC2 board and then are split by the FIU board. They are not multiplexed signals.
