• Each port on the board supports a mix of OSUflex, ODU0, ODU1, and ODUflex signals.

The board supports the Liquid OTN application only when working with the TNU2CTU/TNU4CTU/TNU5CTU/TNG1CXP/TNG3CXP/TNG4CXP board. For the N220 board, each of the IN1/OUT1–IN10/OUT10 and IN11/OUT11–IN20/OUT20 port groups supports a maximum of 1000 OSUflex channels.

• Supports OTU1/OTU2/OTU2e on the WDM side.
• Supports the OTN frame format and overhead processing defined by ITU-T G.709.
• OTU1/OTU2 layer: supports SM overhead processing.
• OSUflex layer: supports PM and TCM overhead processing, and non-intrusive monitoring of PM and TCM overheads.
• ODUk (k=0, 1, 2, flex) layer: supports PM and TCM overhead processing, and non-intrusive monitoring of PM and TCM overheads.

The board supports PM latency measurement at the OSUflex layer.

• Supports ITU-T G.709-compliant forward error correction (FEC) on the WDM side.
• Supports ITU-T G.975.1-compliant AFEC-2 on the WDM side.

• Monitors BIP8 bytes (Bursty mode) to help locate line failures.
• Monitors parameters such as the bias current, temperature, and optical power of the laser.
• Monitors OTN alarms and performance events.

• Supports OSUflex SNCP.
• Supports ODUk SNCP.
• Supports tributary SNCP protection.
• Supports intra-board 1+1 protection (when working with the OLP/DCP/QCP board).
