Hello, my friends.
Today, I'm going to talk about electronic cross-connections between boards.
Inter-board electrical cross-connections are configured between boards to groom ODUk and GE services inside a subrack. They are configured on the U2000.
Specifically, inter-board electrical cross-connections can be configured either between O****ributary and line boards (include PID boards) or between line boards (include PID boards). The line boards include OTN line boards, universal line boards.
Some OTU boards for the OptiX OSN 3800 and OptiX OSN 6800 support inter-board 10GE and GE cross-connections. For details, see section "Physical and Logical Ports".
Port Type
The source and sink ports must be specified when you configure inter-board cross-connections. On the U2000, the following ports can be configured as the source or sink ports of cross-connections:
· ClientLP-n: the logical client-side port of a board in compatible mode, for example, 201(ClientLP1/ClientLP1)-1, where 201(ClientLP1/ClientLP1)indicates the port number and -1 indicates the channel number.
· ODUkLP-n: the logical ODUk port of a board in compatible mode, for example, 161(ODU0LP1/ODU0LP1)-2, where 161(ODU0LP1/ODU0LP1) indicates the port number and -2 indicates the channel number.
· RX/TX-n: the logical client-side port of a board in standard mode, for example, RX2/TX2-2, where RX2/TX2 indicates the port number and -2indicates the channel number.
· n(INn/OUTn)-OCH:1-ODUk:m-ODUp:q: the ODUk-level logical port of a board in standard mode, from which you can learn the service mapping path. The service mapping paths are different in the following ODU timeslot configuration modes: Assign consecutive and Assign random.
§ 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.
§ 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.
I hope it helps. Thank you！
