TS 12749

TS 12749 sets out the rules for competent services that handle telex, teletex, telefax, modem, router and similar devices. The standard is focused on the service organisation itself rather than the equipment design, aiming to provide a consistent framework for repair, maintenance and technical support activities.

Service organisation and technical infrastructure

Its scope covers operating arrangements, physical characteristics, technical equipment and personnel qualifications. In general technical terms, these elements define how a service provider receives faults, performs diagnosis, manages tools and test resources, and keeps the service process orderly and traceable. Because telecommunications and data-transmission devices require appropriate diagnosis and equipment, the service setup needs to be suited to this type of product family.

Personnel and certification approach

The standard also includes personnel specifications and certification. In practical terms, this is associated with the competence of responsible staff, role definitions and the documented qualification of the service structure. The referenced consumer-protection and after-sales-service framework supports the idea that these services should operate as an auditable service system, not only as a repair point.

• The scope brings together classic communication devices such as telex and teletex, as well as telefax, modem and router products.
• The emphasis is on the authorised service structure, not on the product design of the devices themselves.
• Operating rules, premises, technical equipment, personnel and certification form the core framework of the standard.
• Technical fault diagnosis and service competence are especially relevant because these devices perform communication functions.
