TS 12749

TS 12749 is a service standard for the organisation of competent services that handle telex, teletex, telefax and similar communication equipment. It addresses the operating structure of the service provider together with the service premises, personnel competence and technical equipment needed to support repair and maintenance work.

What this kind of service organisation is expected to cover

The main concern is not just fault fixing, but a service arrangement that is orderly, technically responsible and traceable. In general technical terms, telex-like communication equipment combines mechanical, electronic and line-interface elements, so service quality depends on factors such as suitable spare parts, proper test instruments and trained staff. The standard sets rules for organising these services within that framework.

Boundary of the subject matter

The standard does not cover competent services for modem devices used as computer peripheral cards. That distinction matters because modems integrated into computer or terminal environments may be maintained and used under different conditions from standalone communication equipment. TS 12749 focuses on the service arrangement for telex, teletex, telefax and similar equipment, providing a common technical framework for organisations working in this field.
