Abstract

Circuito per impedire ad un radiotelefono impegnato in una chiamata di essere staccato quando si verifica mancanza di potenza, in cui il radiotelefono è collegato con un telefono a filo mediante una linea telefonica. Quando potenza viene a mancare mentre si è impegnati in una chiamata, la linea telefonica è mantenuta eccitata dalla presenza della tensione di linea, ed è generata una musichetta indicativa del mantenimento. Se potenza on è nuovamente in uno stato di mantenimento, allora dati di cancellazione di esclusione potenza vengono trasmessi ad un dispositivo portatile. Se sono ricevuti dati di risposta dal dispositivo portatile, allora lo stato di mantenimento della linea telefonica viene annullato e la musichetta di mantenimento viene arrestata e viene nuovamente eseguita la chiamata attraverso il radiotelefono. Se potenza non è inserita o in stato on nuovamente, o se non sono ricevuti dati di risposta, viene controllato durante un dato tempo se il telefono a filo è sganciato oppure no.Se il telefono a filo è sganciato oppure se il dato tempo è passato, allora lo stato di mantenimento della linea telefonica è annullato e la musichetta di mantenimento fatta cessare. Perciò, la chiamata telefonica viene continuata anche quando si verifica mancanza di potenza in uno stato impegnato della chiamata.
