• SSP and STP simulation: The STINGA SS7 Simulator can be used to simulate against SSPs and STPs.
• SGP and ASP simulation: The STINGA SS7 Simulator can be used to simulate a SGP or one or more APSs.
• Error Tracking: Comprehensive protocol decoding of all user parts and protocol layers makes it possible to track and search for protocol irregularities. Recorded irregular messages may be regenerated with the protocol simulator. This is a very convenient way of reproducing errors in the network.
• Interconnect Testing: A comprehensive conformance test suite frqmework based on the ITU Q.78x series test specifications is included with the STINGA SS7 Simulator.
• Regression Testing: Building script libraries of scripts enables the user to do automated and fast regression testing.
• Mobile Testing: With support for CAMEL, INAP, MAP and SMS, the STINGA SS7 Simulator may be used for mobile testing against BSCs and MSC/VCRs.
• IN Testing: Using the simulator the user may build IN messages to perform IN script testing.
• Call Generation: The STINGA SS7 Simulator is able to generate about 200 calls per second (dependent of the size of the messages to be sent) for load testing.
• Simultaneous Protocol Simulation and Analysis: Possible to simulate on one side of a test object (i.e. a switch) and monitor on the "other" side.
• Remote Control: The STINGA SS7 instrument can be controlled remotely over LAN/WAN (like a dial-up connection). E.g. it is possible to control two separate remote test instruments from one local computer using two B-channels on one ISDN Basic Access.

The SS7 protocol simulator is designed to be used by both skilled and unskilled users: From easy and quick testing by point-and-click to more advanced and flexible script-based testing.

Simulator Processes
The SS7 Simulator product has two simulator processes that can simulate the same or different user parts simultaneously. These simulators can be connected to the same timeslot on the same E1/T1, and to timeslots on different E1/T1s. E.g. one of the simulators can simulate ISUP on one E1, and the other simulator can simulate SCCP on another E1 simultaneously. Both simulator
processes can be configured as Terminal (slave timing) and Net (master timing).

Automatic MTP2 and SMH
Layer 2 mechanisms are handled automatically. Point codes can be specified manually, or they are automatically picked up from the first incoming message.
SLTM/SLTA handshaking is also automatically handled.

Call & Release Call guides
Call setup and termination are easily done from dialogs which guides the user through the generation of outgoing calls and termination of calls. These guides are combined with a Parameter Builder.

Protocols and User Parts
Simulation of different protocols and user parts like MTP, ISUP, TUP/IUP, SCCP, TCAP, MAP, SMS, IN, MWI and CCBS simulation are supported.

Audio Monitoring and DTMF Generator/Detector
The DTMF Generator makes it possible to send single DTMF tones and to specify a series of digits to be sent as DTMF tones. When DTMF tones are sent/received, message are printed in the one-line decoding window. Received DTMF tones and audio is played in the PC-speakers for the PCMCIA solutions, and in the connected handset for the PCI solutions.

Parameter Builder
A parameter builder simplifies the parameter building. Different dialogs are reflecting the specification of the different parameters required to make outgoing calls. For advanced or out of spec modifications, the user is able to make modifications on hex/bit level.

Call Generation
In call generation mode, one simulator process is only sending messages while the other simulator process is only responding to incoming messages. The Call Generator is able to send about 200 calls per second (dependent of the size of the messages to be sent). Sending with “shared flags” is also supported.

Script Language
A powerful and flexible script language makes it possible to set up a required/desired (protocol/terminal) state, both normal and error states. There are no restrictions on neither format nor content of the protocols transmitted/received. Arbitrary manipulation (down to bit level) of messages, parameters and message sequence on the different protocols are allowed. The test scripts may be started manually or they can be automatically triggered by incoming messages.

Remote Control
The simulator application is constructed to be remotely controlled over a IP connection (like a dial-up connection). The graphical user interface is installed on a local computer, while the simulator “agent” is running on a remote computer connected to the test object through the PIST hardware.

Conformance Test Suite Framework
Repeated use of the simulator to perform similar tests is significantly alleviated if a library structure of test scripts is built. Examples of situations where this is recommended are interconnect testing between network operators as well as functional testing, regression testing and conformance testing of terminal equipment and/or network elements. A library of test scripts is available as a framework for the user for building a dedicated test environment. The library is based on the ITU-T Q.782 (MTP Level 3), Q.784 (Basic Call), Q.785 (Supplementary Services) and Q.788 test specifications.
