Abstract

PURPOSE:To bring an automatic answering telephone set to an absence set from a distant place by providing a means for bringing the automatic answering telephone set to an absence set state by a PB signal from a telephone set of a place of going-out. CONSTITUTION:When a ring-back tone is detected, and a PB signal is sent in a state that a trunk line closing switch 6 has been closed, a remote control circuit 9 converts this PB signal to a BNC of 4 bits, and outputs it to a processor 2. The processor 2 compares an output signal from this remote control circuit 9 and a remote control ID code which has been registered in a memory 11 in advance, and when both of them coincide, a remote control back tone oscillating circuit 12 is started and a back tone is sent out, and thereafter, the trunk line closing switch 6 is released and a trunk line is opened, and an absence set switch 1 of an automatic answering telephone set is brought to a set state.

Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to an answering machine that automatically closes a central office line in response to a call from a caller and responds to the caller. It is.

(Prior Art) In order to set a conventional answering machine to an answering state in which it responds to a caller's call, it is necessary to turn on a switch provided on the device. .

(Problems to be Solved by the Invention) Conventional answering machines have a problem in that if you accidentally forget to turn on the switch when you go out, the answering machine does not enter the answering machine state and loses its function as an answering machine. There was a point.

(Means to Solve the Problem) In order to solve the problem, the present invention has a ring tone that detects a call from a caller and outputs a P pulse each time the ring tone rings. a detection circuit, a counter that counts the pulses, a primary set point when setting an answering machine, and a primary setting point when setting an answering machine as the number of rings until the line is closed after a call;
The secondary setting point when the station line is not 1, the PB double signal slow mode control ID code, and the time to open the station line after an arbitrary time after closing the station line based on the secondary setting point. To provide an answering machine which is configured with a timer to manage the answering machine and can set the answering machine from a distance even when the answering machine is not on the answering machine by transmitting a PB double signal while the central office line is closed by the secondary setting point. It is something.

(Function) According to the present invention, even if you accidentally forget to turn on the answering machine when you go out, you can set the answering machine to the answering set state by sending a PB double signal from the telephone you are away from. It can be done.

(Embodiment) An embodiment of the present invention will be described with reference to a block diagram of an answering machine shown in the figure.

When the answering machine 2, which controls the answering machine, detects that the answering machine switch 1 is turned on, the answering machine enters the answering machine state and prepares for an incoming call from the caller. When a ringing signal from a calling party is applied to the central office line connection terminal 3, the ringing tone detection circuit detects the ringing signal and outputs 9 pulses each time the ringing tone rings. The pulse is passed to the counter 5.
counts and outputs the counted number to the processor 2.

The norocessor 2 is configured such that the count number is a first set point;
For example, when it is sensed that the number of times has been reached three times, the central office line closing switch 6 is activated to close the central office line 1~, and the reception circuit 7 is activated to respond to the caller.

Next, when the caller receives a call while the answering switch 1 is not turned on, the ring detection circuit 4 detects the ring signal applied to the central office line connection terminal 1'73, as described above. is detected, the counter 5 counts the number of rings,
Output the count number to the processor 2. When the controller 2 senses that the count has reached a secondary set point (for example, 10 times) that is larger than the primary set point, the controller 2 activates the station line closing switch 6 to close the station line. and at the same time start timer 8. The timer 8 outputs a pulse when a predetermined time has elapsed since it was started.

When the processor 2 senses the pulse output from the timer 8, it restores the office line closing switch 6 to open the office line.

However, when the PB double signal is sent while the central office line is closed,
The remote control circuit 9 detects the PB multiplied signal, converts it into a 4-bit BNC, and outputs it to the processor 2. The processor 2 receives the output from the remote control circuit and the 10 key 1.
0 and the remote control ID code previously registered in the memory 11 via the processor 2. If the two match, the remote control pack tone oscillation circuit 12 is activated to send out a pack tone, and then the central office line is closed. switch 6
The station is restored and the central office line is opened, making it a state where the station is not home. Thereafter, in response to a call from a caller, the central office line is closed at the first set point and the caller is answered.

(Effects of the Invention) According to the present invention, it is possible to set the answering machine to the answering state from a telephone outside the home, which is convenient if you accidentally forget to set the answering machine to the answering state when you go out. Furthermore, since the I+) code is set, there is an effect that no one other than the owner can set the device to the absentee setting state.

Claims (1)

[Claims] By turning on the switch on the main body of the device, it automatically closes the central office line in response to a caller's call, and also has an answering machine state that allows remote control operation using a PB signal while responding. The answering machine detects a call from the caller and the ring tone is set to 1.
a ring detecting circuit that outputs a pulse every time the ring sounds, a counter that counts the pulse, and a first set point and a second set point as the number of times the ring sounds;
Equipped with a remote control circuit based on signals, a remote control ID code, and a timer that outputs a pulse when a given time elapses,
When set to answer, the caller's call is responded to by closing the central office line at the number of times specified by the primary set point, and when not set to answer, the caller's call is responded to. The central office line is closed according to the number of times of the secondary set point, and the central office line is opened after the set time of the timer, but when the remote control ID code is transmitted while the central office line is closed, the central office line is opened. An answering machine characterized in that the telephone automatically enters an answering machine state afterward.
