TS 12739

TS 12739 is a service standard for authorised workshops handling corded, cordless and DECT telephones as well as telephone exchange systems. Its focus is the organisational framework of those service providers, including business practices, premises, personnel and technical equipment.

Service organisation and technical responsibility

In general technical terms, a standard of this kind helps define how a competent service should be structured when it maintains, repairs or otherwise supports telephony equipment. A competent service is typically expected to combine the right tools, trained staff and a clear working process so faults can be diagnosed and addressed consistently. Corded telephones, cordless handsets and DECT systems differ in connection method and operating principle, while telephone exchanges add a broader system perspective; despite those differences, competent service work depends on disciplined procedures, suitable test equipment and staff with the necessary know-how.

What the scope means in practice

• The scope covers the operating rules for authorised services together with requirements for premises, personnel and technical equipment.
• Corded, cordless and DECT telephones may involve different fault patterns and service needs, while exchange systems place greater emphasis on system-wide integrity and interconnection.
• The referenced TS standards point to the technical and safety background that supports this service structure.
• The document is about the service organisation around these products, not the products themselves.

This is a service standard and it has been withdrawn; historically, it remains useful as a reference for how competence, organisation and technical resources were framed in the telephony service sector.
