Features

This page contains an overview of the features of the STINGA V5 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
  • Free conformance test suits included with the system
  • Easy to develop new test suits based on existing ones
  • Regression Testing: To build test suites is a breeze and enables the user to perform automated regression testing in a cost-efficient way.

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 simulation. A combination of SS7, BICC, V5 and ISDN PRA test instruments are supported.

Simulator Processes

The V5 Simulator product has 16 layer 3 simulators (0-7 is used with S0 and 8-16 used with S1). The simulators can simulate both Local exchange (LE) and Access Network (AN).

Simulation Concept

Since there are a lot of protocols involved, it is necessary that these protocols can communicate. A script file contains instruction for one protocol, and is located in one specific folder.

A script can be started in three different ways:

  1. Manually by the user
  2. Automatically triggered by an incoming message
  3. Triggered from another simulator

Call & Release Call guides

Call setup and termination for both PSTN and ISDN 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

Simulation of different protocols like Pr, LinkC, CC, BCC, PSTN, ISDN BA and ISDN PRA simulation 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.

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

Conformance Test Suite

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 for ISDN BRI and PSTN. The library is based on the ITU-T G.964/G.965.
