The WDM-side signals of the TN11LSX/TN12LSX board can be regenerated using another TN11LSXR board. The WDM-side signals of the TN13LSX/TN14LSX board can be regenerated using the TN12ND2/TN52ND2/TN53ND2/TN57ND2/TN55NO2/TN55NH2/TN53NQ2/TN54NQ2/TN57NQ2 board.

Whether regeneration is supported on ND2 boards
ND2 boards can regenerate one channel of OTU2/OTU2e signals in both directions.

Functions of the TWC and RWC boards on BWG 320G
The TWC board is applied in DWDM optical terminals and optical regenerator devices, and is located at the transmit end. The RWC board is applied in DWDM optical terminals and optical regenerator devices, and is located at the receive end. The functions of the TWC and RWC boards on BWS 320G are as follows: 1. The TWC boards convert optical signals sent from the SDH devices to the wavelengths required by the WDM system by O/E/O conversions. Different TWC boards convert optical signals of different wavelengths. 2. The RWC board transmits optical signals to the SDH devices. It chooses 1310 nm or 1550 nm based on the SDH wavelengths.

Whether TN53NQ2 can function as the regeneration board for TN11LSX, TN12LSX, and TN13LSX
When TN53NQ2 functions as a regeneration board, its Board Mode needs to be set to Electrical Relay Mode (in an OSN 8800 platform subrack or OSN 8800 UPS subrack) or Optical Relay Mode (in a subrack of another type). TN53NQ2 can be interconnected with TN13LSX. When TN53NQ2 is interconnected with a TN12LSX or TN11LSX board, its FEC Mode must be set to FEC.
