Descriptions

syncProtectionUnit — ETSI published formal attachments

This object class is specific to synchronisation protection. Instances of this object class are used to represent a relationship between a timing source and the timing generator(or a timing physical termination). All instances of this object class will act in the protecting role (i.e. there will not be a syncProtectionUnit with the protecting attribute set to FALSE), in order to ensure the consistency of the priority list. This object class can be created by the OS or the NE. When it is created by the OS, the OS must provide a value for the attribute unreliableResourcePointer.
