ISDN/PRA Protocol Simulator

STINGA Protocol Simulators simulate and generate realistic network traffic. It is an essential tool for network providers in validating new services, versions, or products for Quality of Service (QoS), conformance, and user experience.



STINGA ISDN PRI Simulator is a cost-efficient test tool which performs ISDN PRI protocol simulation over TDM.


The simulator supports conformance, functional, regression, mobile, and load testing, from the prototyping-stage to final product. Testing new services, products, or versions early in the development phase saves time, prevents errors, and ensures interoperability between network elements. When commercially released and distributed, all new network elements are verified to function in a real network environment and to deliver on its premises.

Generate various traffic conditions

STINGA ISDN PRI Simulator can generate both real network conditions and custom traffic towards specific or all parts of a network. It can also regenerate problems or irregularities that have already occurred in a real network environment. This makes error tracking and searching easier, and customer experience can easily be tested to ensure high quality.

A Conformance Test Suite Framework is included with all STINGA Protocol Simulators. The framework contains a large number of test scripts and templates to simulate calls, data traffic etc. towards one or several parts of a network. Test scripts and templates can easily be customized for specific tests in or between network elements.

Expert Support & tailored solutions

To better fit our customers’ needs and requirements, we provide them with custom made and tailored solutions. All STINGA products are adapted to new technological changes and new protocols and versions are added continuously. Other protocols and national protocol variants are implemented on customer request.

Expert support and product demonstrations are offered online via GoToMeeting. Contact us to request and schedule an appointment.
