Assign consecutive mode

Hi friend!

The service mapping paths are different in the following ODU timeslot configuration modes: Assign consecutive and Assign random.

A. In the Assign consecutive mode, level-by-level service mapping is performed from lower rates to higher rates, for example, ODU0->ODU1->ODU2. In this example, the logical port is represented as 1(IN1/OUT1)-OCH:1-ODU2:1-ODU1:2-ODU0:1, which means the first ODU0 in the second ODU1 of the first ODU2 on optical port 1.

B. In the Assign random mode, cross-level service mapping is performed from a low rate to a high rate, for example, ODU0->ODU2. In this example, the logical port is represented as 1(IN1/OUT1)-OCH:1-ODU2:1-ODU0:1, which means the first ODU0 in the second ODU2 on optical port 1.

Thanks!

Hello!

If the ODU timeslot configuration mode is set to Assign random, the board supports Any->ODU0->ODU2->OTU2. If the ODU timeslot configuration mode is set to Assign consecutive, the board supports Any->ODU0->ODU1->ODU2->OTU2. The difference between the two modes lies in whether the ODU1 chip is involved in mapping processing for intra-board cross-connections.

Best regards!
