E1_63_E3_3—Port numbers 64, 65, and 66.
2.1.4.5 Auto Discovery
The ONS 15310 MA SDH supports automatic discovery of connected elements. CTM can connect to one
node and retrieve information about all connected nodes. The first time CTM connects to a node, it
retrieves only the IP address of the connected node; CTM does not retrieve the node name. However,
CTM must report this element to the users. Because the IP address is unique, CTM initializes the name
of the newly discovered element with the IP address. An object creation event is generated for this
managed element with the IP address as the name. Later, CTM connects to this element and retrieves all
information, including the actual name, and an AVC event is generated for the managed element name.
The NMS listens to the AVC event for the managed element name and invokes
managedElementManager::ManagedElementManager_I:: getManagedElement.
