Custom Dictionary

The Diameter > AVP Dictionary > Custom Dictionary page displays all proprietary AVPs defined by the operator in the system. Base Dictionary AVPs are not displayed in the Custom Dictionary list.

AVP names that are defined in the dictionary can be used in creating Rule Templates and in provisioning Rule Sets.

The Attribute Name, AVP Code, AVP Flag settings, Vendor ID, Data Type, and Protocol must be specified in the AVP definition.

If the Data Type is Enumerated, then the name of the Enumerated Type is also included.

If the Data Type is Grouped, then the list of Grouped AVPs appears in the dictionary.

The values for AVP definitions are described in Diameter Custom Dictionary elements.

The Diameter > AVP Dictionary > Custom Dictionary page allows the operator to:

• Add new proprietary AVPs and additional standard AVPs familiar to the system
• Overwrite AVP definitions in the Base Dictionary by specifying them in the Custom Dictionary with a different definition. The AVP Code, Vendor ID, and Attribute Name must remain the same in the changed definition.

  If the Attribute Name of an AVP appears in both the Base and Custom Dictionaries, then the Custom Dictionary definition is used when the AVP is selected in Rule Template Actions and Conditions.

• Clone AVPs.

On the Diameter > AVP Dictionary > Custom Dictionary page, you can perform the following actions:

• Filter the list to display only the desired entries. All column headings are supported in the filters except the Flags.

• Sort the list entries, in ascending or descending order in a column (except for Flags), by clicking the column heading. By default, the AVPs are sorted by Attribute Name in alphabetical order.
• Click Insert.

  You can add a new AVP and its values.

  If the maximum number of AVPs (1024) already exist in the system, then the Diameter > AVP Dictionary > Custom Dictionary [Insert] page does not open and an error message displays.

• Select an AVP definition in the list and click Edit.

  The detailed definition for the selected AVP is displayed. You can change the AVP definition except for the AVP Code, Vendor ID, and Attribute Name.

• Select an AVP definition in the list and click Delete to remove the selected AVP definition from the dictionary.

• Select an AVP definition in the list and click Clone AVP to clone the selected AVP definition.
