ABSTRACT:
In a relay station for use in a radio telephone network, which relay station includes a time storage unit composed of a time delay member connected to be switched, in response to recognition of a calling signal by its associated evaluator, from a reset state in which it is inactive to a set state in which it triggers emission of an identification signal after a delay period which is characteristic of the relay station and which differs from that of all other relay stations in the network, a member responsive to detection of such selective calling signal by its associated evaluator subsequent to recognition of a calling signal and prior to emission of a resulting identification signal for returning the time delay member to its reset state and preventing emission of that identification signal, and a member for automatically returning the time delay member to its reset state at the end of a time interval which follows recognition of a calling signal and is longer than the longest delay period characteristic of any relay station in the network.
