TS 12739

TS 12739 is a service standard that sets out rules for competent service providers working on cord telephones, cordless telephones, DECT telephones and telephone exchangers. It addresses not only repair activity itself, but also the organisational structure of the service business, its physical facilities, technical equipment and staff characteristics as the main elements shaping service quality.

Core elements addressed in a competent service setup

The scope covers the rules for the management arrangement, structural characteristics, technical equipment and personnel profile of organisations providing maintenance and service for these devices. The technical intent is to define the institutional framework that supports consistent, traceable and orderly service delivery. Because telephony equipment is central to user communications, the service organisation is expected to be built with an appropriate level of discipline and readiness.

Technical context for cord, cordless and DECT systems

In general technical terms, cord telephones rely on a direct line connection, cordless telephones use a radio link between the base unit and handset, and DECT telephones are based on digital cordless communication technology. Telephone exchangers manage multiple internal and external lines within a communications system. For that reason, service competence requires the ability to diagnose different connection types and system architectures correctly, use suitable equipment and provide dependable support to users.

This TS edition is a withdrawn standard, so it serves as a historical reference rather than a current normative requirement. Its rules remain useful for understanding how competent services for this class of telephony equipment were organised and equipped.
