A common WDM service can be converted into an ODUk SNCP service. However, an ODUk SNCP service will be interrupted when it is converted into a common WDM service.
A common WDM service can be converted into an ODUk SNCP (Subnetwork Connection Protection) service. However, when an ODUk SNCP service is converted back into a common WDM service, the protection is interrupted, causing service disruption. This is because SNCP provides path-level protection with automatic switching, which is lost during conversion back to a simpler WDM configuration. HCIP-Transmission highlights this limitation in protection mechanisms when migrating between service types, important for network planning and service continuity management.
