GenITC: Quadrus Corporation’s Generic Interface Test Computer

The Quadrus GenITC is the Swiss army knife of Integration and Interface test tools, built from the ground up to modify and/or inject any kind of message into any system’s communication interfaces. The GenITC generates:

  • Valid messages conveying nominal commands and statuses
  • Valid messages conveying off-nominal commands and statuses (including seriously off-nominal messages, such as catastrophic failure)
  • Internally inconsistent messages, e.g. VMF messages that violate conditions
  • Corrupted, unrecognizable messages

GenITC is available with fully functional fixed-layout, JREAP, & VMF message parsers.


GenITC logs, monitors, modifies, delays, injects, and deletes system communications as directed by a controlling scenario, providing a wealth of test and integration possibilities:

  • Modifying individual message fields as they pass through the network—with the ability to recognize specific message content and select specific ones to mangle
  • Injecting message(s) containing any desired content: nominal, off-nominal, or invalid
  • Delaying and deleting messages
  • Duplicating messages, with or without transmission delays
  • “Interface patching” to convert messages from one system into those for another
  • Simple logging

GenITC communicates with your systems using your communication technologies: TCP/IP and UPD, Serial (EIA/TIA 232, 422), Variable Message Format (VMF), JREAP and NTDS.


Whether you need interface emulation, message recording and analysis, simulated message traffic, sim-over-live message injection or real-time on the fly message manipulation in a working system, GenITC can provide that capability. DICE can provide the same capabilities for multiple simultaneous interfaces. Either way, you can drive your system and test it in ways that would otherwise be impossible without extensive coding of drivers and instrumentation of the code under test.

TCP/IP and UPD Testing/Simulation

GenITC with the TCP/IP module is a powerful tool for the development, integration, and interface testing of TCP/IP message based systems.

GenITC/TCP/IP is message set neutral. Since all message sets are defined in a user-configured message database, implementing any or all TCP/IP based message sets is simply a matter of creating the corresponding message definitions in the database. Keeping message definitions up-to-date is a matter of running GenITC’s GUI DataMan component to manually update the message definitions.

The message database makes experimenting with, and evaluating, variations of messages for research and prototyping a simple matter of updating message definitions with DataMan.

Any syntactically valid TCP/IP message can be constructed, without consideration for case or condition. The GenITC can easily generate a message containing data that violates the case requirements for that message. Obviously this provides the means by which invalid messages can be fed into a system to test its ability to recognize and reject such messages.

Any message content can be generated, whether targeted at minimally or fully-populated messages. Any value can be put in any field, whether legal or not—if the values of 12-15 are undefined for a 4-bit field, GenITC can put 12, 13, 14 or 15 into that field.

GenITC can respond appropriately to the messages it receives. GenITC’s core capabilities include modifying the messages that pass through it, creating and sending new messages, killing, duplicating, and delaying messages, and responding conditionally to the contents of messages. Data can be pulled out of any field present in a TCP/IP encoded message, or packed into one. Message data can be retained from one message to another to adapt responses to the actual flow of messages, rather than just always producing a fixed, or limited range of, responses.

GenITC is a leap beyond canned TCP/IP message generators and simulators—configurable in message content and behavior. There is no better tool than GenITC for rigorously and pervasively wringing out a TCP/IP message-based system’s interfaces.

EIA/TIA 232/422 Serial Testing

As of GenITC 4.0, Serial communication via EIA/TIA 232 and 422 compliant serial communications may also be tested. This add-on capability extends all the benefits of TCP/IP and UDP testing to the serial interface. This capability provides full flexibility for all compliant communications at the full range of the serial hardware detected on the test system. GenITC systems can be shipped with the standard serial interface or customized to your needs with specialized 3rd party hardware.

JREAP/TADIL Testing/Simulation

JREAP Processing entails processing TADIL-J messages with a JREAP wrap around. The Joint Range Extension Application Protocol (JREAP) is based upon the Open System Interconnection (OSI) layered structure and focuses on the application layer; however, it recognizes that certain network and transmission layer services provided by JTIDS and MIDS terminals for Link 16 are not provided by all communications media. The JREAP enables tactical data to be transmitted over digital media and networks not originally designed for tactical data exchange.

The JREAP-capability option of GenITC allows GenITC to function as a smart network node (rather than as a JREAP processor, in the strict Mil-Std-3011 sense), passing and processing message traffic, using the TCP/IP or UDP protocols, under the control of a user-generated test scenario.

GenITC/JREAP also provides JREAP Packing and JREAP Validation checkboxes in the interface control area. Checking JREAP Packing enables message decomposition and recomposition, while JREAP Validation allows GenITC to process erroneous and extraneously formed JREAP messages. With JREAP Validation enabled, GenITC will attempt to construct a valid JREAP Application Block from the message components received for missing JREAP Portions, and missing Application Headers. In addition, this capability enables the application to update the Application Block Message Length field, the Number of J-Words, and the Number of Blocks for Free Text (Coded/Uncoded) messages.

VMF Force Multiplier

GenITC with the VMF capability is a powerful tool for the development, integration, and interface testing of VMF message based systems.

All GenITC/VMF message sets are defined in a user-configured message database. Keeping message definitions up-to-date is a matter of running GenITC’s GUI DataMan component to update the message definitions. The message database makes experimenting with, and evaluating, variations of messages for research and prototyping a simple matter of updating message definitions with DataMan.

Any syntactically valid VMF message can be exchanged with the target system. GenITC can interpret the content of received messages and react to them based on a user generated scenario. In addition to valid VMF data, GenITC can be scripted to generate repeatable error conditions, such as invail VMF fields, or message fields out of range. Obviously this provides the means by which invalid messages can be fed into a system to test its ability to recognize and reject such messages.

GenITC can respond appropriately to the messages it receives, again, based on a user generated scenario. GenITC’s core capabilities include modifying the messages that pass through it, creating and sending new messages, killing, duplicating, and delaying messages, and responding conditionally to the contents of messages. Data can be pulled out of any field present in a VMF encoded message, or packed into one. Message data can be retained from one message to another to adapt responses to the actual flow of messages, rather than just always producing a fixed, or limited range of, responses.

GenITC is a leap beyond canned VMF message generators and simulators—configurable in message content and behavior. There is no better tool than GenITC for rigorously and pervasively wringing out a VMF message-based system’s interfaces.

NTDS Testing

As of GenITC 4.0, Navy Tactical Data System (NTDS) communications may also be tested. This add-on capability extends all the benefits of TCP/IP and UDP testing to the NTDS. This capability provides full flexibility for all compliant communications at the full range of the NTDS hardware detected on the test system and has been fully qualified using Serial NTDS E communication. GenITC systems can be shipped with the NTDS hardware that was used for qualification or customized to your needs with specialized 3rd party hardware.
