This section describes how to configure the 52TOM board in a ring network.
Service Requirement
Refer to Figure 1, the optical NEs (ONEs) A, B, C and D form a ring network, and all the ONEs function as OADM stations.
User1 and User2 communicate with each other. One bidirectional OTU2 service is available between station A and station B. On station A, the TOM board accesses eight Any services (100 Mbit/s to 2.5 Gbit/s) and then converts them into two ODU0 services or one ODU1 service. The two ODU0 services or one ODU1 service is accessed to the NS2 board, and is then converged with other accessed services as one OTU2 service.

NOTE: - The OptiX OSN 8800 T16(NA), OptiX OSN 8800 T32(NA) and OptiX OSN 8800 T64(NA) does not support distributed cross-connection.
- The OptiX OSN 6800A/3800A does not support the ODU0 cross-connection.
- When the board is in the cascading mode, and the port is in the ODU0 tributary mode, the OptiX OSN 8800 T16(NA), OptiX OSN 8800 T32(NA) and OptiX OSN 8800 T64(NA) does not support the grooming in ODU1 granularities.
Board Configuration Information
In this example, a TOM board and an NS2 board should be configured on both station A and station B.
