- About MATRIXX Diameter Integration
  MATRIXX Diameter Integration provides information about MATRIXX Engine Diameter support and configuration.
- Diameter Gateway
  The following information describes the Diameter Gateway.
  - Diameter Gateway Overview
    Diameter Gateway is a Diameter server that allows communication between MATRIXX Engine and a network entity requesting service through the Diameter protocol.
  - Diameter Gateway Support for 5G Non-Standalone Architecture
    MATRIXX supports 5G Non-Standalone Architecture deployments by including extended fields for 5G RAN in Gx messages to enable the high-bandwidth data flows available in 5G networks.
  - Supported AVPs
    The MATRIXX Diameter Dictionary is defined in the diameter_dictionary.xml file and contains definitions for the Diameter AVPs, functions, and Diameter-to-MDC mappings implemented in MATRIXX Engine.

    - Diameter AVPs for MATRIXX Policy Application
      MATRIXX Engine supports the Sy and Gx interfaces for policy control.
  - Configuring the Diameter Protocol
    You can configure and customize the Diameter Dictionary and the Diameter protocol.
  - Working with the Diameter Protocol
    The Diameter protocol is comprised of two basic parts: the Diameter Base Protocol and Diameter applications.
  - Handling VoLTE Announcements
    MATRIXX Engine can return Voice over Long-Term Evolution (VoLTE) Announcement-Information AVPs for Diameter LTE (Long-Term Evolution) sessions. The AVPs define the list of pre-quota announcements to play to the subscriber using VoLTE technology.
  - Handling Diameter Errors
    Errors with the Diameter protocol fall into two categories: protocol errors and application errors.
- External Diameter Gateway
