The figure depicts the PDC TMF 620 API architecture.

Components:

• Enterprise Product Catalog: Initiates the request.

• PDC REST Service Manager (PDC RSM): Receives and processes requests, interacts with PDC/BRM.

• OAUTH: Provides authentication for requests.

• TMF 620 to PDC Mapping: Converts data to PDC compatible format.

• PDC Service: Processes the request within PDC.

• PDC/BRM: Receives data and interacts with Billing and Revenue Management system.

Flow:

1. Enterprise Product Catalog sends TMF620 API request to PDC RSM.
2. PDC RSM authenticates the request via OAUTH.
3. PDC RSM maps request data to PDC format.
4. PDC processes the request within PDC.
5. PDC interacts with PDC/BRM as needed.
6. PDC sends a response back to the Enterprise Product Catalog.

This is a simplified overview. Refer to the documentation for a detailed flow of the REST API.
