The Level 4 Converter is a value-added feature to the Ribbon DSC - SP2000. This converter enables the conversion of SS7 L4 traffic such as Integrated Service Digital Network User Part (ISUP) and Signaling Connection Control Part (SCCP) messages and their parameters between two SS7 variants (referred to as variant in this guide). Despite standards being in place for SS7 networks, there are over 100 different National variants throughout the world. Not only can the variants be distinct, but they can also be dependent on the actual switch implementation. The Level 4 Converter can be configured to address the customization in its deployed networks.

The Level 4 Converter handles conversion between two variants. The supported conversions include:

The Level 4 Converter also can be used for STP migration. For more information about this functionality of the Level 4 Converter, refer to STP Migration with the Level 4 Converter.

Note

If you require any additional conversions, contact Sales for pricing and availability.

For added flexibility, the default conversion rules can be dynamically modified to pass through or discard messages and parameters.

The Process Event feature that appears in the UI, but is not described in this guide, provides an alarm type which ensures that the applications in all slots function as expected. With this feature, each application defines its own concept of functioning as expected, which means that the configuration/database files are synchronized and loaded, inter-peer connections are correctly established, and the peer applications are ready to process traffic.

If the application and its peer processes do not function as expected, an alarm is raised that is visible on the system's alarm panel. For more information about alarms, refer to the appropriate section in the DSC Alarms Guide .
