Message Automation & Protocol Simulation™ (MAPS) for ISDN

GL’s Message Automation & Protocol Simulation™ (MAPS) is a powerful Protocol Test platform-supporting a wide range protocols such as SS7 over TDM (T1/E1), ISDN over TDM, GSM-A interface & GSM-Abis interface over TDM, Megaco, SIP, and MGCP.

GL’s MAPS-ISDN is an advanced protocol simulator/tester for ISDN simulation over TDM (T1E1) and generates high volumes of ISDN traffic. The tester can simulate ISDN signaling as defined by the ITU-T standards. Currently this test tool is used to perform testing using ISDN protocol messages over T1/E1, and offers a complete solution for testing, troubleshooting, and maintenance of devices and networks implementing PRI ISDN. It is useful to test ISDN products designed for either U or S/T interface, including network terminations, Type 1 terminating equipment, and terminal adapters.

MAPS-ISDN also incorporates the flexibility to modify ISDN call parameters & message contents (arbitrary manipulation of messages, information elements and message sequence on the different protocols). This flexibility ensures that the MAPS-ISDN communicates with the system under test. It is even possible to emulate a complete ISDN connection (switch to subscriber) all in the same PC with a dual interface card or dual laptop analyzer. Link status (Lap D) is also configured.

MAPS-ISDN supports powerful utilities like Message Editor and Script Editor which allow new scenarios to be created or existing scenarios to be modified using ISDN messages and parameters.

GL also provides a GUI based ISDN protocol analyzer (optional application – xx100) for on-line capture and decode of the signaling in real-time both during tests and as a stand-alone tracer for live systems.


Protocol Standards

This test tool can be also be used to perform protocol conformance testing as per the following specifications

  • ISDN - ITU-T Recommendation Q.931

MAPS - ISDN Testing Features

  • ISDN simulation over TDM (E1/T1)
  • Multiple T1/E1 line interfaces supported
  • Access to all ISDN Message Parameters such as Setup, Connect, Release messages, and more
  • Switch and Subscriber Emulation
  • Provides various release cause codes such as rejected, no user response, user busy, congested, and so on to troubleshoot the problems in ISDN
  • Supported on Windows® 2000/XP/Vista operating systems

Automatic Simulation Behavior (generates and responds to calls/ messages):

  • Call Generation Configuration: Allows independent outgoing communications. The Call Generation interpretation of establishing call is to invoke the required scripts for call transfer.
    • Editing utilities allow access to Mandatory Parameters and Information Elements using Message Templates, Import, and Export files
    • Change parameters values using an utility Profile Editor
    • Impairments can be applied to messages to simulate error conditions
    • High volume traffic options – DTMF/MF generator/detector, single and Dual Tone, Tx and Rx of Voice files (scripted) and analyzing the received voice files in VQT for Voice Quality Test
    • Retransmission of messages with specific interval
    • Provides protocol trace with full message decoding, custom trace, and graphical ladder diagrams of call flow with time stamp while simulation is running
    • Option to run the test for multiple iterations
    • Quick configurations to create multiple entries
    • Interactive GUI to view status, results, call information, total iterations to be done, and number of completed iterations
    • Provides the associated captured events and error events during call simulation




  • Call Reception Configuration: Allows configuring incoming communications to handle all possible signaling and call Control messages for responding to the call requests.
    • Automatic response to incoming messages - Processes the ISDN messages received based on the script specified in the script configuration window
    • Provide the result of the test with detail protocol decode and ladder diagram



Software Architecture

  • Script based & protocol independent software architecture
  • Quick-testing to complex testing
  • Customization of call flow and messages
  • Generate and respond to calls/ messages
  • Monitor the call flow graphically (ladder diagrams)

Working Principle

The message templates form the backbone of MAPS application. The Message Editor is a powerful utility of MAPS application, which allows users to create any number of message templates with user-selected protocol fields and default values for each protocol field.

The protocol fields in message templates comprises of Mandatory Parameters and Information Elements, and these can be accessed by scripts as variables using import/export files.

The scripts comprises of sequence of commands that performs the required operation using pre-defined message templates. The Script Editor is another powerful utility of MAPS, in which sequences of message templates can be grouped together in an order to create call flow.

Profile consists of values assigned to the variables. Profiles can be created using a utility called Profile Editor where the values can be assigned to the variables. The original value of the variables in the message template is replaced with these assigned values.

MAPS provides the ability to create any number of scripts to simulate a real-time scenario with MAPS-ISDN and DUT.
