The unified CGIN resource adaptor includes a simulated International Telecommunications Union (ITU) standard Transaction Capabilities Application Part (TCAP) stack that can be used for testing without the need for a full TCAP stack environment.

It’s a simulator …
The simulator includes most of the behaviour of a real SS7 network, but it is not necessarily identical. For example, it may only communicate with other instances of the simulated ITU TCAP stack. |
How does it work?
Each ITU TCAP simulator instance (resource adaptor entity or Scenario Simulator) connects to other ITU TCAP simulator instances using a subset of SUA over a proprietory TCP-based protocol.
The simulator is configured with one or more TCP/IP network addresses to connect to, plus an address to listen on. PC/SSN routing is configured automatically using standard SUA dynamic routing configuration.
A single pointcode/subsystem number pair may be routed to more than one simulator instance, allowing for operation within a Rhino cluster. The following diagram shows a simple 2-node Rhino cluster loaded with an ITU TCAP simulator resource adaptor entity connecting to the Scenario Simulator.
