You can only perform this task when logged into an NOAM.
From the View Tab, all NPA Split information can be displayed. Each field can be used as a filter option when viewing NPA splits.
If you click View while all three fields are empty, the GUI displays all NPA splits found in the PDB database. If the Save Results checkbox is check marked, the results are also saved to a CSV file named NpaSplitReport.guiadmin.<timestamp>.csv. This file can then be viewed and downloaded in the HLR file management area (The Network Element Name field on the page).
If Save Results was check marked, the CSV file is generated.
