Abstract

Programmer for fixed radio channel translator, for a radio mobile system integrated into the public telephone network intended to operate in conjunction with a code converter, characterized in that it comprises: a circuit (α1) which, received by the control unit to send the acoustic call signal to the mobile user, it recognizes the mobile user's response (γ signal) and generates the response criterion (GA) for the control panel; a time circuit (α2) that, if the time interval between sending the acoustic call signal to the mobile user and its response, collected by (α1) (if it is the mobile user who is calling, between sending the central and selection start) exceeds a preset minimum, activates an unlock circuit (α4); another time circuit (α3) which, if the time interval between the end of the radio channel availability signal emission and the start of reception of the mobile user identification exceeds a predetermined minimum, activates the blocking circuit (α4); a circuit (α5) that in case of absence for a time greater than a predetermined minimum of the carrier (end of connection or prolonged fading) activates the unlocking circuit (α4); and because the unlocking circuit (α4) which, sent by circuits (α2), (α3), (α5) and by the error signal (E) generated by the code converter, causes the mobile user to send the unblocking criterion and, successively, starts again the emission of the availability signal in the radio channel.
