The invention relates to a method for the management of a plurality of decentralized customer terminals by means of a bidirectional communications connection between a central unit and customer connection units associated with the customer terminals, wherein the central unit transmits at least one synchronous radio control program to a plurality of customer connection units by means of at least one longwave transmitter via a central radio ripple control channel, wherein each customer connection unit triggers a predefined process at least one associated customer terminal in dependence on the received radio control telegram, and wherein each customer connection unit transmits at least one data telegram which includes information related to the associated customer terminal to the central unit via a decentralized return channel which is separate from the radio ripple control channel; wherein the transmission of the data telegram to the control unit takes place based on time, based on an event and/or in dependence on a previously received radio control telegram. The invention furthermore relates to a management system for a plurality of customer terminals which is operable in accordance with the method in accordance with the invention.
