Abstract
Briefly, according to the invention, the interface device comprises matching device (20 and 22) for coupling a duplex information signal (21 and 23) to a simplex or a duplex radio (6) which provides a corresponding information signal (27) acknowledged by the half duplex or full duplex radio (6). Additionally, a signal detecting means (24) determines a desired signal strength and controls an interrupt signal (32). A means for sending (26) the interrupt signal (32) to the radio (6) sends the interrupt signal once the signal detecting means detects the desired signal strength. Finally, the interface device of the present invention comprises a means for sending (26) the corresponding information (27) once the interrupt signal is sent.
