Figure 2-59 shows project I, which is a ring network consisting of sites A, B. Sites A and B are OADM sites. ODUk SNCP is used to protect client services between sites A and B.

There are the following service requirements:

One OTU-2 service is required between sites A and B and ODUk SNCP needs to be configured to protect the line boards and OCh fibers.

Application

As described previously, end-to-end protection is required for the A-B section. In this example, OTUk signals are received on the client side. According to the ODUk SNCP configuration principles described in Introduction, SNC/I require the least overheads and supports end-to-end signal monitoring. Therefore, SNC/I protection is recommended for this scenario.

Service Planning

The board attributes, protection attributes, service information, and OTN overheads must be planned for each site.

Example Description

Figure 2-60 shows project S, which is a tangent ring network consisting of sites A, B, C.

  • Site B is electrical regeneration sites.

Site A dually feeds a client service to sites B. The service electrically processed by the line boards at sites B and then is transmitted to sites C.

There are the following service requirements: one OTU-2 service is required between sites A and C and ODUk SNCP needs to be configured to protect the line boards and OCh fibers between sites A and B, and sites B and C.
  • ODU2 SNCP on the A<->B section
  • ODU2 SNCP on the B<->C section
NOTE:
Two ODUk SNCP groups with the sub-layer monitoring (SNC/S) and uses the TCM1 overhead are configured at site B between sites A and B to implement selective receiving.
  • In group 1, the N3 board functions as the source working board, the N4 board functions as the source protection board, and the N5 board functions as the sink board.
  • In group 2, the N4 board functions as the source working board, the N3 board functions as the source protection board, and the N6 board functions as the sink board.
