Procedure
Step 1 Choose Service > SDH Protection Subnet > Manage SDH Protection Subnet from the Main
Menu.
Step 2 Right-click the protection subnet to be deleted and choose Delete from the NM, Delete from
the NE, or Delete All from the NM from the short-cut menu.
NOTE
The methods of deleting a protection subnet are as follows:
l Delete from the NM: If Delete from the NM is selected, the relations between the protection subnet and
each logical system on the NE side are deleted so that the fibers can be deleted and reloading can be
performed. This command is not delivered to the NE and does not affect the services. The deleted protection
subnet can be located by using the search feature. The U2000 locates it according to the NE layer protection
information.
l Delete from the NE: If Delete from the NE is selected, the protection subnet, logical systems on the NE
side, and all the services on the protection subnet are deleted. The deleted protection subnet cannot be restored
and needs to be created again.
l Delete All from the NM: If Delete All from the NM is selected, the data of the protection subnet except
the fibers at the network layer is deleted. The deleted protection subnet can be located by using the search
feature. It is recommended that you do not select this option, because a large amount of data is deleted.
Step 3 Click Yes in the Operation Prompt dialog box indicating that the operation succeeded. Then,
the Operation Result dialog box is displayed.
NOTE
If Delete from the NE is selected, you need to confirm the operation again.
Step 4 Click Close.
