General

This Recommendation presents the general principles for employing those maintenance features and capabilities of international transmission systems and equipment which are based on alarm information.

It describes a set of strategies, in addition to the maintenance philosophy in Recommendation M.20, to use these alarm-based features and capabilities in an effective and efficient manner. This Recommendation is also intended to address the interactions between alarms of digital and analogue transmission systems and equipments.

Alarm interactions for mixed analogue/digital transmission systems and equipment are under study.

While this Recommendation discusses the strategy to employ these features and capabilities, the actual arrangements to provide and use them are left to the discretion of the Administrations.
