Abstract: A telecommunications unit (for example a subscriber terminal or a base station) is arranged to communicate over a wireless link with a further telecommunications unit of a telecommunications system in order to allow traffic data to be passed between the telecommunications unit and the further telecommunications unit. The telecommunications unit comprises a management processor operable to handle management data, and inductive loop logic coupled to the management processor and operable to allow management data to be passed between the management processor and a portable management unit via a separate wireless link between the inductive loop logic and external inductive loop logic associated with the portable management unit. This provides a particularly efficient technique for the transmission of management data between the telecommunications unit and the portable management unit, without the need for a physical contact to be provided on the exterior surface of the telecommunications unit.
