|Backplane capacity||The total bandwidth is 200 Gbit/s.|
|Client-side service type||
When 100GE services are received on the client side and mapped into ODUflex, the client equipment must support flow control response.
|Service mapping mode||100GE service: Supports Bit Transparent Mapping ODU4, MAC Transparent Mapping ODU4, and MAC Transparent Mapping ODUflex.|
|FEC coding||Supports ITU-T G.709-compliant forward error correction (FEC) on the client side when the client-side service type is OTU4.|
|Client 1+1 protection||Supported|
Supports the tributary SNCP protection, only when the client side service type is OTU4.
|L1 Service Encryption||Supported
When receiving OTU4 services on the client side, the board does not support the encryption.
|ALS||Supported on the client side when 100GE services are received.|
|IEEE 1588v2||The board supports the TC, TC+OC, BC, and OC modes when the client-side service type is 100GE(MAC transparent mapping).|
The G402/G404 board supports the BC mode when the client-side service type is 100GE(GFP-F).
The board does not support ITU-T G.8273.2 when the system control board is U2CTU.
|Outband DCN||Supported communication over ESCs on the client side when OTU4 services are received.|
|Test frame||Supported when the client-side service type is 100GE.|
|Channel loopback||Not supported|
