Background on TL 9000

TL 9000 requirements were developed by the QuEST forum (The Quality Excellence for Suppliers of Telecommunications Leadership), comprised of leaders in the telecommunications field. The QuEST forum used ISO 9000 as a baseline and the requirements of existing industry standards and practices in developing the TL 9000 requirements. The development of sector-specific requirements for hardware, software and services quality system and metrics requirements is an essential part of TL 9000. Find out more about QuEST forum at www.questforum.org.

What are the benefits of TL 9000?

  • Establish a common set of quality system requirements and effective performance and cost-based metrics to guide processes.
  • Evaluate results of quality system implementation.
  • Drive continuous improvement.
  • Enhance customer/supplier relationships.
  • Protect the integrity and use of telecommunication products and services.

For whom are these requirements intended?

TL 9000 applies to all suppliers of telecommunications hardware, software and services.


Registration to TL 9000

TL 9000 Quality system requirements will allow for registration to the hardware, software and services quality system requirements, or any combination of the three categories, coupled with the appropriate Metrics. Multiple registration options will allow users to register according to the nature of their business.

The three registration options (or any combination) being offered are as follows:

  • TL 9000 - H (Hardware quality system requirements and metrics)
  • TL 9000 - S (Software quality system requirements and metrics)
  • TL 9000 - V (Services quality system requirements and metrics)

Registrar Accreditation

The QuEST forum has made it very clear that it will only accept third-party registrations from Registrars that meet the requirements defined in Appendix "B" – Code of practice for TL 9000 Registrars. UL meets all these criteria and will be in the first group of Registrars accredited.
