Channel loopback

Supports inloops and outloops on channels.

NOTE:

ODU0 channel loopbacks are supported only when the port working mode is the ODU1_ODU0 mode (OTU1->ODU1->ODU0).

Port loopback

• Supports inloops and outloops on the client side.
• Supports ODUk inloops and ODUk outloops on the client side.

NOTE:

• When the board works in ODU1 convergence mode, you must configure intra-board cross-connections before loopbacks. Otherwise, the loopbacks become abnormal.

• Monitors BIP8 bytes (Bursty mode) to help locate line failures.
• Monitors B1 bytes to help locate faults.
• Monitors OTN alarms and performance events.
• Monitors parameters such as the bias current, temperature, and optical power of the laser.
• Supports the remote monitoring (RMON) of Ethernet services.
