The unified CGIN resource adaptor includes a simulated Transaction Capabilities Application Part (TCAP) stack that can be used for testing with the need for a full TCAP stack environment.
The simulated TCAP stack supports both International Telecommunications Union (ITU) and American National Standards Institute (ANSI) TCAP.

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 TCAP stack. |
How does it work?
Each TCAP simulator instance (resource adaptor entity or Scenario Simulator) connects to other TCAP simulator instances using a subset of SUA over either SCTP or a proprietory TCP-based protocol.
The simulator is configured with one or more 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.
