At 03, the voice synthesizing circuit 16 is activated, and a voice message indicating that the station line cannot be transmitted due to the restriction dialing is sent to the cordless handset 2 via the wireless unit 11, and then at step 304, the station line disconnection process is performed. To end the control. On the other hand, if the process proceeds to step 305, the control unit 17 gives the dial information sent from the slave unit 2 to the line control circuit 14, and shifts to the station line calling operation.

FIG. 4 is a diagram showing a procedure for transmitting and receiving a signal between the above-mentioned master unit 1 and slave unit 2. First, from cordless handset 2 (1)
When the station line transmission request signal is sent to the master unit 1 at the timing of, the master unit 1 captures the station line, and then at the timing of (2), the master unit 1 transmits a signal indicating that the station line can be transmitted. Return to.
As a result, the slave unit 2 sends the dial information of the destination to the master unit 1 at the timing (3). Therefore, the master unit 1 checks whether this dial information is caught by the restriction dial, and if it is caught (4 ), The dial transmission disable signal is transmitted to the slave unit 2. Subsequent to this, the base unit 1 sends an audio signal notifying that the station line cannot be transmitted due to dial restriction to the handset 2 at the timing (5), and then outputs a voice generation end signal at the time (6). Send to. As a result, the idle signal is transmitted from the handset 2 at the timing (7), and the base unit 1 disconnects the office line communication path formed with the handset 2 at this point.

FIG. 5 is a time chart showing a state transition between the base unit 1 and the handset unit 2 when a station line is transmitted. When the station line button 24 of the cordless handset 2 is pressed, as shown in FIG. 5 (A), a call circuit for connecting to the telephone line 8 is formed between the cordless handset 2 and the parent device 1, and at the same time, the cordless handset is formed. The machine becomes ready for station line transmission at the timing shown in FIG. 5 (B). After that, dial information is generated from the handset 2 at the timing of FIG. However, in this case, since the dial information is a restricted dial, a voice message is sent from the base unit 1 to the handset 2 at the timing of FIG. 5D, and then the call shown in FIG. The circuit is eliminated.

According to the present embodiment, when the dial information input from the slave unit 2 for transmitting the office line is the restriction dial, the master unit 1 returns a voice message notifying the dial information to the slave unit 2. After disconnecting the station line, the cordless handset can surely know the reason why the station line is disconnected and can take appropriate measures. It should be noted that the same effect can be obtained by notifying by a specific signal that the station line cannot be transmitted because the master unit 1 has caught the slave unit 2 on the restriction dial.
