CCNDC Mapping Configuration

The MAP-Diameter IWF > Configuration > CCNDC Mapping page is used to configure mapping of a Country Code (CC) plus National Destination Code (NDC) to a Diameter Realm in the MD-IWF application.

CCNDC Mapping is used when translating a MAP Request message to a Diameter Request message, when the MAP message Global Title Address (GTA) digits are in MGT format (for ITU, the SCCP CdPA Numbering Plan is E.214 ).

When a CCNDC Mapping entry matches the CCNDC in the GTA digits, the configured Diameter Realm from the entry is populated into the Destination-Realm AVP of the Diameter Request Message.

The fields are described in CCNDC Mapping Elements.

On the MAP-Diameter IWF > Configuration > CCNDC Mapping page, you can:

Filter the list of entries, to display only the desired entries.
Sort the list entries in ascending or descending order by by clicking the column heading. By default, the list is sorted by CCNDC in ascending ASCII order.
Click the Insert button.

The Diameter Common > Network Identifiers > CCNDC Mapping [Insert] page opens. You can add new CCNDC Mapping entries. If the maximum number of CCNDC Mapping entries (2500) already exists in the system, the Diameter Common > Network Identifiers > CCNDC Mapping [Insert] page will not open, and an error message is displayed.
Select a CCNDC Mapping entry in the list, and click the Edit button.
The Diameter Common > Network Identifiers > CCNDC Mapping [Edit] page opens. The selected CCNDC Mapping entry can be edited.
