The sim TCAP stack emulates most of the behaviour of a real SS7 network. It is embedded in both the unified resource adaptor and the scenario simulator and can be used for testing without the need for a real TCAP stack.
The Scenario Simulator is a new, very powerful and flexible testing tool for simulating traffic in SS7 networks. You use it to build test environments for testing network elements and services.
The scenario editor is a visual tool for building call flow scenarios for use with the scenario simulator.
