Service direction in ODUk SNCP protection

9

ODUk SNCP uses the dual feeding and selective receiving function of electrical-layer cross-connections to protect services on line boards and OCh fibers.

Principles of ODUk SNCP protection
Generally, ODUk SNCP protection needs to be configured using one tributary board and two line boards to implement dual feeding and selective receiving of ODUk services in the OTN network.

Switching time of ODUk SNCP protection
The switching time of ODUk SNCP protection cannot exceed 50 ms, excluding the detection time.

ODUk SNCP service configuration procedure
ODUk SNCP service creation by trail: (1) Configure TCM overheads of the line board. (2) Set board parameters. (3) Create a client trail. (4) Create ODUk SNCP protection. (5) Check ODUk SNCP protection status. ODUk SNCP service creation by single site: 1. Configure ODUk SNCP protection at the transmit site. (1) Configure OTN overheads of the line board. (2) Set board parameters. (3) Create ODUk SNCP protection. 2. (Optional) Configure an electrical regeneration site. (1) Set board parameters. (2) Create bidirectional electrical cross-connection services. 3. Configure ODUk SNCP protection of the receive site. 4. Check ODUk SNCP protection status.

Procedure for configuring ODUk SNCP services
The procedure for configuring ODUk SNCP services is as follows: 1. Determine the type of the ODUk SNCP to be configured. 2. Configure the OTN overheads for line boards. 3. Create an SNCP service.

ODUk SNCP protection of the SNC/I type
ODUk SNCP (SNC/I) protects services against defects detected at the ODUk link connection (such as server layer trails and server/ODUk adaptation functions). It does not detect defects at the ODUk layer itself. Connections may be indirectly monitored by using the data that is inherently available from the server layer network.
