Now, after the incoming call command is transmitted to the base station in step 34, the control means 6 of the base station 2 not only detects reception of the call command from the base station but also monitors the output of the incoming signal detection means 7 in steps 36 and 37. and step 36
When the base station detects that the output indicating the call status is no longer present, the base station transmits an end command to the mobile station, and when the mobile station receives the end command, the control means 20 of the mobile station stops the ring tone sending means 27 and starts the call. Ends sound output. or,
When an output indicating an automatic response is detected in step 37, a termination command is transmitted to the base station in step 38,
In step 39, the A relay is turned on, and in step 40
Then, the response sending means 11 is driven. As a result, the mobile station 3 cancels the ringing tone, closes the line, automatically responds, and outputs a response message to the line via the communication circuit 13, switching contact 81, and line connection terminal 1. Then, a response message is being sent (steps 41, 42, 48).
．． 44) The control means 6 of the base station monitors the output of the control signal detection means 9, the output "call command" of the machine status detection means 8, and the output of the response transmission means 11, and sends a response message from the response transmission means 11. When the output indicating the end is detected (step 44), the message recording means 12 is driven in step 45.As a result, the caller's message is recorded at line connection terminal 1 and switching contact a.
The message is recorded in the message recording means 12 via the 1-call screen 13.

During recording of the message (steps 46, 47, 48, 49), the M control means 6 of the base station monitors the control signal product 8 means 9, the aircraft status detection means 8, the call command, and The end of call detection means 10 is monitored, and the end of call detection means 1 is monitored.

Turn off A relay at . As a result, the recording of the message is completed, the line is released, and the state returns to the state of detecting the presence or absence of a call.

While sending a response message (or recording a message), a certain control signal is sent from the caller, which is a DTMF signal in this embodiment.
(in other embodiments, but not limited to this) is detected by the control signal detection means 9,
The output of the control signal is input to the control means 6 of the base station. When the control means 6 detects the presence of a control signal from the control signal detection means 90 in step 41 (or step 46), it stops the response sending means 11 (or stops the message recording means 12) in step 52, and then proceeds to step 52. A command for outputting a special call melody that is sent only when a control signal is detected in 53 (hereinafter referred to as special call command)
is transmitted from the base station to the mobile station 3, and at the same time, the special call melody sending means 16 of the base station 2 is driven. Then, the control means 20 of the mobile station 3 which has detected the special call command drives the special call melody sending means 28 of the mobile station 3 and turns on the B relay. As a result, the special call melody is sent out to the line via the call circuit 13, the switching contact 81 and the line connection terminal 1, and is output from the base station via the amplifier circuit 17 and the speaker 18, and is further output from the base station via the switching contact b1 amplifier circuit 29

Sending special call melody (steps 54, 55, 56.
57) The control means 6 of the base station monitors the output of the root state detection means 8, the call command, the output of the end of call detection means 10, and a 30-second guard timer. At this time, the base connection terminal 5
When the telephone device connected to the telephone closes the line, this is detected by the root state detection means 8, and an output indicating the root on state is inputted to the control means 6. The control means 6 performs step 5
4, when the base station detects the output indicating the root on state of the root state detection means 8, the base station transmits an end command to the mobile station 3 in step 58, stops the special call melody sending means 16, and in step 51, the A relay is activated. Turn off. The control means 20 of the mobile station 3 which has detected the termination command stops the special call melody sending means 28 of the mobile station and turns off the B relay.

As a result, the line transmission of the special ringing melody and the output from the base station 2 and mobile station 3 are completed, and the device itself returns to the ring detection state again, but the communication between the caller and the telephone device connected to the base connection terminal 5 is terminated. Calls can be made.

Meanwhile, while the special call melody a is being sent, the operation unit 31 of the mobile station 3
If there is a call input (step 55), the control means 20 of the mobile station 3 transmits a call command to the base station 2, stops the special call melody sending means 28, turns off the B relay, The control means 6 of the base station 2 detecting the call command stops the special call melody sending means 28 of the base station. As a result, the transmission of the special paging melody through the line and the output from the base station 2 and mobile station 3 are completed, and a conversation between the calling party and the mobile station of the device becomes possible. Further, if there is an end of the call while the special call melody is being sent (step 56), the end of the call is detected by the call end detection means 10, and an output indicating this is input to the control means 6, so that the special call melody is output. is completed, and the central office line is released. If it is detected in step 57 that 30 seconds have elapsed since the output of the special call melody, the output of the special call melody is stopped in step 59 as in the case of the root on, and a response message is sent again in step 40. .

If the line of the telephone device connected to the root connection terminal 5 is closed (step 42 or 47) while the response message is being sent (or while the message is being recorded), the root state detection means 8 detects this and sends the response message. After stopping (or stopping recording of the business), the central office line is opened, and the caller can talk to the base.
If a call is input from the operation unit 31 of the mobile station, a call can be made between the caller and the mobile station of the device.

As explained above, according to this embodiment, the control signal detecting means 9 detects the control signal sent from the caller, and the means outputs the special call tone 8 based on the output of the control signal detecting means. A certain special call melody sending means 16,28 is provided in both the base station 2 and the mobile station 3, and a root connection terminal 5 for connecting another telephone device in parallel with the base station 2, and a root connection terminal 5 for connecting another telephone device in parallel with the base station 2. By providing a root state detection means 8 which is means for detecting the state of the connected telephone device,
