Centre for Testing and Interoperability

Our Centre for Testing and Interoperability (CTI) provides hands-on support and assistance to our technical committees, the Third Generation Partnership Project (3GPP™) and the oneM2M Partnership Project on the application of testing and validation techniques in standards-making.

The CTI has extensive expertise in:

  • best practices in interoperability, testing and protocol specification
  • validation of standards
  • conformance testing
  • interoperability testing
  • organization of interoperability events (Plugtests™)
  • the use of specialized tools and techniques

Our booklet, ‘Solving the Challenge of Interoperability’, introduces the CTI and its work.

Developing test specifications

The CTI’s main task is the planning and development of conformance and interoperability test specifications. Many of these are used in external certification schemes such as those of the Global Certification Forum (GCF) and the DECT™ Forum.

To ensure the quality of the tests, we validate them in various ways:

  • in-house
  • in collaboration with commercial test laboratories and recognized test tool suppliers
  • among the ETSI membership

Plugtests events

We have been a pioneer among the standardization bodies in recognising the importance of achieving interoperability through testing. The CTI organizes our world renowned Plugtests interoperability events for testing our standards. These events also allow engineers from different companies to come together to test their product implementations against relevant standards to ensure interoperability.

Since the late 1990s, we have organized an average of 12 such events every year, worldwide. We co-operate closely with our members in industry to provide activities that meet market need. Our programme of events covers a wide range of technologies.

We have the experience and resources to provide complete organizational and logistical event management, as well as full technical support (test infrastructure, test plans, reporting tools etc.) – even for technologies that are outside the scope of our standardization activity.

Specialized tools and languages

ETSI is a world leader in the use of specialized techniques (see ETSI Portal) to overcome the inadequacies of natural languages (such as English) in describing complex interactions.

The CTI works closely with our committee on Methods for Testing and Specification (TC MTS) accessible via the ETSI Portal.
