Consider the following regarding the DSC Platforms terminology.

  • Release 16.1.0 supports the DSC SWe (on KVM, VMware, and OpenStack) and the DSC 8000.

  • The terms Sonus Signaling System and DSC Platform as well as Sonus Signaling Systems and DSC Platforms may be used interchangeably in the 16.1.0 Documentation Library. 

  • The term SS7 Database Application (SDA) may be referred to as SigFlex in the 16.1.0 Documentation Library.

  • The term Signaling Network Activation Manager Interface (SNAMI) may be referred to as Signaling Engineering and Administration System (SEAS) in the 16.1.0 and Documentation Library. 


This platform supports Virtual Machines (VMs). The supported number of VMs on the DSC SWedepends on the licensing configuration and the capacity of the KVM and the VMware hosts. Two of these VMs (required by default) are in virtual slots 1 and 2. These VMs are used for both management and routing purposes and are referred to as

  • Routing and Management VM1 [virtual slot 01 – (RTNG_MGMT_CPU)]

  • Routing and Management VM2 [virtual slot 02 – (RTNG_MGMT_CPU)]

All other VMs are used for routing purposes and are referred to as Routing VMs [Slots 3 to 20 – (RTNG_CPU)].

For more information about the VMs, see the appropriate chapter of the Installation Guides and the Platform Manager User Guide.

DSC 8000

This platform supports Management, Routing, and Application CPUs. Consider the following regarding these CPUs:

  • Management traffic is supported on the Management CPUs.

  • DSC and SIGTRAN traffic are supported on the Routing CPU (can be the same CPU but different subnets).

  • DSC Database (DB) is supported on the Application CPU.

For more information about the DSC 8000 CPUs, see the appropriate chapter in the DSC 8000 Hardware Installation Guide.

To identify the supported applications on a particular CPU

  1. From the Main Menu, click Licensing.

  2. Under the License Features (per CPU) heading, click the CPU on which you want to identify the licensed applications.

  3. Click Update.

References to Routing and Management VMs (Management CPUs) and Routing VMs (Routing CPUs)

The 16.1.0 Documentation Library refers to Routing and Management VMs and Routing VMs where this reference may also apply to Management CPU and Routing CPU, respectively, if you are configuring a DSC 8000 system.

Therefore, in each section of the 16.1.0 Documentation Library that Routing and Management VM or Routing VM is mentioned, as a reminder, the following information is provided (see Naming Conventions). 

Naming Conventions

For simplicity, the 16.1.0 Documentation Library uses the terms Routing and Management CPU (VM) and Routing CPU (VM) in place of the DSC SWe Web UI terms RTNG_MGMT_CPU and RTNG_CPU, respectively. Likewise, the terms Management CPU and Routing CPU are considered synonymous with DSC 8000 Web UI terms MGMT_CPU and RTNG_CPU, respectively. Using the following table, apply these terms as required for your respective system.

All occurrences of VM apply to the applicable CPU if your system is a DSC 8000.

PlatformVM and CPU NameWeb UI Abbreviation
DSC SWeRouting and Management CPU (VM)RTNG_MGMT_CPU
DSC 8000Management CPUMGMT_CPU

For detailed information about terminology for the DSC Platforms, see Terminology.

Limitations for the DSC Platforms

DSC Platform in this Documentation Library refers to the DSC 8000 or the DSC SWe on a KVM or VMware Host. The software for these platforms is similar; any differences will be clearly identified in the documentation as required.

  • Some applications for the DSC Platformssuch as Gateway Screening (GWS), Global Title Translation (GTT), Point Code Emulator (PCE), Diameter Signaling Controller (DSC), and so on are license dependent. If your system is not licensed for an application, the Web-based UI (also referred to as Web UI) side menu bar does not display the associated button to access the application. For a screen capture of the Web UI Main Menu with all applications enabled and running and for a description of each Main Menu button, see the Web UI and Menu UI Guide.

  • The alarm panels in the screen captures that appear in this library may display a number of alarms, because the screen captures are obtained using systems under test.

  • Some file names and Web user interface (UI) references have not yet been updated to reflect the acquisition of PT by Sonus Networks.

For other limitation and exclusions for this release, refer to DSC Platform 16.1.0.R00, 16.1.0.R01, and 16.1.0.R02 Release Notes.
