PURPOSE:To easily inspect an operating state from a user side, by allocating a status code on every state transition of the call connection sequence of a CE(repeater) and an RTEL(radio telephone set), outputting the status code to the outside at every generation of a status or action. CONSTITUTION:In a case that the CE and the RTEL are constituted in such a way that they are connected to personal computers on the market, a printer is connected to the personal computer to store the history of the call connection sequence. When a call is set by issuing the call from the RTEL, the status code of the state transition from the issuing of the call to the setting of the call is transmitted in order from the CE to the personal computer, and the personal computer prints out the code on the printer. In the RTEL, the status code is stored in a microcomputer, and a stored status code is transmitted to the personal computer by sending the output request of the data from the personal computer, and the personal computer outputs the data. If a failure occurs in a process to the setting of the call, the history of the status code of the CE or the RTEL print-outputted is referred, and the cause of the failure can be decided. |
