dsc headerDiameter Signalling Controller

The SVI-DSC provides a carrier grade Diameter signalling product delivering any combination of routing (DRA), inter-working (IWF) and network edge (DEA) functionality.

DSC Functionality

dsc functionality


The SVI_DSC provides any combination of Diameter Routing Agent (DRA), Diameter Edge Agent (DEA) and Interworking Function (IWF) for deployment in todays Diameter network. The SVI_DSC modular software build means it can also be deployed as an integrated product with Squire Techs SS7 STP product (SVI-STP) and Session Border Controller product (SVI-SBC)


DRA Diameter Routing Agent
