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.
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.
