What are the Functions and Features of Huawei 40G Line Board NS3

Huawei NS3 board achieves cross-connection at the electrical layer, and to provide OTN interfaces and ESC. The TN56NS3 board supports hybrid transmission of OTN and SDH services.

The available functional versions of the NS3 board are TN11, TN52, TN54, TN55, and TN56.

• Only the OptiX OSN 8800 supports ODU0/ODU3.
• The relay mode is only supported by the TN54NS3/TN55NS3/TN56NS3.
• For the TN54NS3 board:
  • When the board is equipped with 40 Gbit/s-multirate-2km optical modules, it does not support OTU3e on the WDM side and ODU2e on the backplane side.
  • When the board is equipped with 800ps/nm-C band-tunable-ODB-PIN or 800ps/nm-C band-tunable-DQPSK-PIN optical modules, the preceding restriction does not apply.
• Only the TN56NS3 board supports SDH functions and features, including SDH overhead, physical clock (OCS), Electrical-layer ASON (SDH), SDH protection, and VC-4 channel loopback.
