Features

This page contains an overview of the features of the STINGA ISDN PRI Simulator product. You can also download the product brochure for a detailed overview of the product features.

Testing

  • Supports both black box and white box testing.
  • Use it for component, function, integration, system, acceptance and conformance testing.
  • Easy to develop new test suits based on existing ones.
  • Comprehensive conformance test suite included free of charge.
  • Regression Testing: To build test suites is a breeze and enables the user to perform automated regression testing in a cost-efficient way.

Simulator Processes

The ISDN PRA Simulator product have two simulator processes which can be connected to two different E1/T1/J1s. Both simulator processes can be configured as Terminal (slave timing) and Net (master timing).

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.

Protocols and User Parts

Simulation of different protocols like DSS1 layer 2 & 3, Euro-ISDN layer 2 & 3, National ISDN-2, X.25, Layer 6 and 7, ASN.1 and PPP & IP in B channel are supported.

Audio 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. This function is available both through the user interface and scripts.

Call Generation

In call generation mode, one simulator process is only sending messages while the other simulator process is only responding to incoming messages. A user friendly user dialog provides automatic connection to a microphone and the PC speaker.

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. DTMF scripting is supported including branching dependent on the received DTMF string. This is a very comprehensive feature for testing DTMF dependent services. It is very useful when the simulator sends a setup without the called number and if it is required to send the called number in the user channel and for test of value added services in the active phase of a call.

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 PC, while the simulator “agent” is running on a remote PC connected to the test object through the 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 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.

Cost-efficient Windows-based Test Instruments

All software and hardware components are running on standard notebook and desktop PCs with Windows, providing cost efficient IT service, fast learning curve, easy and cheap access to replacement units.

Same User Interfaces for all Products Reduce Costs

All test instruments from Utel Systems are based on the same windows user interface framework. The user do not have to focus on how to use different applications, meaning full focus on different protocols and network technologies in use. Same decoding format for monitor and simulator results in time efficient testing.

Simultaneously Protocol Simulation & Analysis

Different protocol simulators and analyzers can easily be used together on the same PC simultaneously. It is possible to simulate on one side of a test object (i.e. a switch) and monitor on the “other” side. By installing two PCMCIA cards in one notebook, it is possible to use both cards to monitor two E1/T1/J1 interfaces or to use one card for protocol monitoring and the other for protocol simulation. A combination of SS7, BICC, V5 and ISDN PRA test instruments are supported.

Open script format

Content and order of any message of information element can be changed. The simulator can therefore simulate any regular or irregular/incorrect protocol implementation and be adapted to new protocol elements.
